Alaskans were rattled by a 7.8 magnitude earthquake Tuesday night that sent people fleeing for higher ground in case of a possible tsunami, before the warning was canceled.
<p>The quake struck offshore at 10:12 p.m. local time and was located around 500 miles southwest of Anchorage and around 60 miles southeast of Perryville, Alaska, <a href="https://www.cbsnews.com/news/earthquake-alaska-tsuani-warning-evacuations-kodiak/" target="_blank">CBS News reported</a>.</p>
<p>"This is a very significant earthquake in size," Alaska Earthquake Center seismologist Michael West told the <a href="https://www.adn.com/alaska-news/2020/07/21/strong-earthquake-prompts-tsunami-warning-from-alaska-peninsula-to-western-kenai/" target="_blank">Anchorage Daily News</a>. </p>

<p>The earthquake initially triggered a tsunami warning for South Alaska, the Alaska Peninsula and the Aleutian Islands, CBS News reported.</p>
<p>"Based on the preliminary earthquake parameters... hazardous tsunami waves are possible for coasts located within 300 kilometers of the earthquake epicenter," the Pacific Tsunami Warning Center said, according to CBS News. </p>
<p>The warning prompted evacuations in towns and cities including Kodiak, Sand Point, Unalaska and Homer, the Anchorage Daily News reported. </p>
<p>"We were in a (city) council meeting and started feeling it rocking, and by the time I got home from the council meeting then the warnings were going and had to turn back around," Unalaska City Manager Erin Reinders told the Anchorage Daily News.</p>
<p>Meanwhile, in Kodiak, residents sheltered in Kodiak High School and the local Catholic school while also trying to protect themselves from the coronavirus.</p>
<p>"We've got a high school full of people. I've been passing out masks since the first siren sounded," Kodiak School District superintendent Larry LeDoux told the Anchorage Daily News. "Everything's as calm as can be. We've got probably 300, 400 people all wearing masks."</p>

<p>West told the Anchorage Daily News that Tuesday's earthquake was more or less the same type as the Great Alaska Earthquake of 1964.</p>
<p>That earthquake was the strongest ever recorded in North America, with a magnitude of 9.2, CBS explained. The quake and following tsunami killed more than 250 people.</p><p>"These are the style of earthquakes which can be very tsunami-producing," West told the Anchorage Daily News.</p>
<p> The fact that Tuesday's quake occurred offshore reduced shaking, West said. Officials did not think the shaking caused any damage.</p>
<p>"No reports of any damage," Kodiak Police Sgt.

By Fabian Schmidt
Researchers have discovered an interesting similarity in two of the largest recent earthquakes in Japan and Chile: a strange large-scale ground movement back and forth in the months leading up to the quake.
<p>These earthquakes are among the 10 strongest ever measured: the 2011 Tohoku-oki seaquake off the coast of Japan registered 9.0 on the moment magnitude scale, triggering the devastating tsunami that destroyed the Fukushima Nuclear Power Plant. It was the fourth-strongest quake in the last 100 years. The 2010 seaquake off the coast of the Maule region of Chile, occupies sixth place on the list. </p><p>Researchers from the Geoforschungszentrum Potsdam (GFZ) along with collaborators from Chile and the United States have now discovered astonishing similarities in the months before both quakes: multiple strange reversals of ground motion — an extremely slow "wobbling" of the continental plate, so to speak.</p><p>Lead author, <a href="https://www.gfz-potsdam.de/en/staff/jonathan-bedford/sec41/" target="_blank">geophysicist Jonathan Bedford</a>, along with a team of geodesists, geologists and seismologists, evaluated the movements of ground stations of the Global Navigation Satellite System (GNSS).</p><p>These ground stations continuously track the distances to multiple GNSS satellites that orbit the earth in elliptical orbits. After these distances have been established, and given the estimates of the satellite positions, geodesists are able to define the motion of points on the Earth within a terrestrial reference frame.</p><p>In Japan, there is a very dense network of ground stations. Although the network in Chile was not as dense in 2010, it was sufficient to obtain the data.</p>
Whole Continental Plate 'Wobbles'
<p>Bedford and his colleagues analyzed how the ground stations in Japan and Chile had moved in the five years before the two quakes. They noticed that the motion of the continental plate on which the stations are located had been reversed several times in the last five months before the quake (in the case of Japan) and seven months (in the case of Chile). The researchers published <a href="https://doi.org/10.1038/s41586-020-2212-1" target="_blank">their results</a> in the scientific journal <a href="https://www.nature.com/articles/s41586-020-2212-1" target="_blank">Nature</a>.</p><p>Both plate boundaries are subduction zones. Subduction is the process of one plate diving under another. In both study regions, the oceanic plates are subducting underneath the continental plates and meet at a place called the trench, which for both cases is submerged under the ocean. Normally, the continental plate is pressed by the oceanic plate and thus pushed away from the trench. However, the geophysicists have now discovered that this movement was first reversed in the direction of the trench, then away from the trench, then back towards the trench again.</p>Same Movement Over Thousands of Kilometers
<p>They call this phenomenon "wobbling," due to its appearance in the GNSS time series. The amplitude of this movement is not particularly great — it was only between 4 and 8 millimeters — but Bedford points out that this is significant compared to the relative plate motion that can be a few centimeters per year. Furthermore, the spatial extent of the signal extended thousands of kilometers along the plate boundaries.</p><p>"It is a common assumption that deeper subduction proceeds at a fairly constant speed in between large earthquakes," says Bedford. "Our study shows that this assumption is an oversimplification. In fact, its variability might be a key factor in understanding how the largest earthquakes nucleate." </p><p>With global satellite tracking now becoming better and better, and with accurate data available for the first time in decades, earthquake researchers have an ever-increasing ability to make such observations.</p><p>"We can now trace movements back decades," says Bedford. "In the next stage, we'd like to monitor the changes in near real time."</p>Not Suitable as an Early Warning System
<p>Until now, seismologists have been more able to say <em>where</em> large earthquakes are likely to occur — less able to say <em>when</em>. By simply calculating the magnitude of the last large earthquake in a region and knowing the average relative plate velocity, one can estimate when that fault will be mature enough to sustain a repeat event, although there are great uncertainties in this approach. This is because sometimes a fault will rupture only over a smaller area (e.g. with a "large" magnitude 8 event) and other times it will rupture over many magnitude 8 regions all at once (e.g. in a "mega" magnitude 9 event).</p><p>Could an observed untypical plate movement therefore give us a better warning of an imminent earthquake? Not really. </p><p>"It would not be wise for a geophysicist to issue such a warning," is Bedford's sobering answer. "The observed signals of this study are not necessarily precursory movements of a major quake."</p><p>More research is necessary and as a matter of principle, people in known earthquake areas should not let their guard down. </p><p>"The general public should always be prepared," Bedford warns.</p>

Idaho residents were rattled Tuesday evening by the biggest earthquake to shake the state in almost 40 years.
<p>The 6.5 magnitude quake struck just before 6 p.m. local time 73 miles northeast of Meridian, <a href="https://apnews.com/ee4018c9240bd4768dbea25c40712198" target="_blank">The Associated Press reported</a>. It caused no known damage or injuries, but plenty of surprise. </p>

By Richard Aster
Multiple strong and damaging earthquakes in southern Puerto Rico starting around Dec. 28, 2019 have killed at least one person, caused many serious injuries and collapsed numerous buildings, including a multistory school in the town of Guánica that luckily was empty at the time. These quakes are the most damaging to strike Puerto Rico since 1918, and the island has been under a state of emergency since Jan. 6, 2020.
<p><br>This flurry of quakes includes onshore and offshore events near the town of Indios and along Puerto Rico's southwestern coast. So far it has included 11 <a href="https://www.usgs.gov/faqs/foreshocks-aftershocks-whats-difference?qt-news_science_products=0#qt-news_science_products" target="_blank">foreshocks</a> – smaller earthquakes that preceded the largest event, or mainshock – with magnitudes of 4 and greater. Major quakes occurred on Jan. 6 (magnitude 5.8) and Jan. 7 (magnitude 6.4 mainshock), followed by numerous large aftershocks.</p><p><a href="https://scholar.google.com/citations?user=khkdN24AAAAJ&hl=en" target="_blank">Seismologists like me</a> are constantly working to better understand <a href="http://www.ecowatch.com/tag/earthquakes">earthquakes</a>, including advancing ways to help vulnerable communities before, during and after damaging events. The physics of earthquakes are astoundingly complex, but our abilities to forecast future earthquakes during a strong sequence of events in real time is improving.</p><p>Forecasting earthquakes is not a strict prediction – it's more like a weather forecast, in which scientists estimate the likelihood of future earthquake activity based on quakes that have already occurred, using established statistical laws that govern earthquake behavior.</p>
<h2>An Undersea Fault Zone</h2><p>Puerto Rico spans a complex boundary between the Caribbean and North American <a href="https://pubs.usgs.gov/gip/dynamic/tectonic.html" target="_blank">tectonic plates</a>, which are sliding past each other in this region at a relative speed of about 2 centimeters per year. Over geologic time, this motion has created the Muertos Trough, a <a href="https://seismo.berkeley.edu/blog/2020/01/07/deadly-earthquakes-in-the-muertos-trough.html" target="_blank">15,000-foot depression in the sea floor</a> south of the island.</p><p>This plate boundary is riddled with interconnected fault structures. The present activity is occurring on and near at least three interrelated large faults.</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjUwNzkwMi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxMzM2OTQ1M30.C0LJHoMTL55fyQZTmDiwfJoDGDE7LL05nkvSztuLjvY/img.jpg?width=980" id="9c749" class="rm-shortcode" data-rm-shortcode-id="35f84d58ad0b90d9de549e5688b53c59" data-rm-shortcode-name="rebelmouse-image" />
Multiple faults crisscross the eastern Caribbean. Those outlined in red have a potential to generate a large earthquake. The arrow at top right shows the direction of the North American plate's motion relative to the Caribbean plate. Red stars denote intensity centers for past earthquakes. USGS
<p>Faults are pre-existing weak zones between stronger rocks. In response to surprisingly small force (stress) changes, they rapidly slip to produce earthquakes. The "hair-trigger" nature of fault slip means that predicting the precise timing, location and size of individual quakes is extremely challenging, if not impossible.</p><p>During an earthquake sequence, changing stresses act on nearby fault systems as stress is gradually redistributed within the earth. This process generates thousands of protracted aftershocks.</p><p>Many earthquake sequences simply start with the mainshock. But it is not especially rare for scientists to recognize after the fact that foreshocks were occurring before the main event. Improvements in earthquake instrumentation and analysis are helping scientists detect foreshocks more often, although we have not yet figured out how to recognize them in real time.</p>
<h2>Will One Shock Lead to Another?</h2><p>Researchers have known for over a century that the rate of earthquakes following a mainshock declines in a way that we can characterize statistically. There is also a well-established relationship between the magnitude of earthquakes and their relative number during an earthquake sequence. In most seismically active regions, for a decrease of one magnitude unit – say, from 4.0 to 3.0 – people can expect to experience about 10 times as 3s compared to 4s in a given time period.</p><p>Using such statistical relationships allows us to forecast the probability and sizes of future earthquakes while an earthquake sequence is underway. Put another way, if we are experiencing an aftershock sequence, we can project the future rate of earthquakes and what magnitudes we expect those quakes to have.</p>

The second-most active volcano in the Philippines belched to life on Sunday when it sent a cloud of ash miles into the air that forced thousands to evacuate and shuttered the airport in the capital of Manila.
<p>The eruption of the Taal volcano continued Monday when it began gushing lava, <a href="https://apnews.com/11cacd39a4aa509097d44d090e20c93d" target="_blank">The Associated Press reported</a>.

Mysterious hums that were heard around the world in 2018 have now been identified as the rumblings of a magma-filled reservoir deep under the Indian Ocean, announcing the birth of an underwater volcano, according to a new study, as CNN reported.
<p>Researchers started to detect seismic movement from the birth of the volcano in May and June of 2018, which eventually led to a humming noise that radiated thousands of miles away from where the volcano was born about 22 miles off the coast of Mayotte in the Indian Ocean, one of several in the Comoros archipelago found between Mozambique and Madagascar, as <a href="https://www.cnn.com/2020/01/09/world/seismic-hum-volcano-scn-trnd/index.html" target="_blank">CNN</a> reported.</p><p>For months, the forming volcano produced tiny <a href="http://www.ecowatch.com/tag/earthquakes" target="_self">earthquakes</a> and a slight humming too weak to feel. That changed on Nov. 11, 2018 when the new volcano announced its birth by sending seismic waves all over the world that were felt in Kenya, Chile, Canada and Hawaii, nearly 11,000 miles away. For almost half an hour, the seismic waves produced a humming that got louder and louder, as <a href="https://www.washingtonpost.com/nation/2020/01/09/earthquake-creates-underwater-volcano/" target="_blank">The Washington Post</a> reported.</p><p>Researchers developed new seismological methods to create a year-long timeline to reconstruct what happened during the formation of the new volcano. They published their results this week in the journal <a href="https://www.nature.com/articles/s41561-019-0505-5" target="_blank">Nature Geoscience</a>.</p><p>Geologists around the world were alerted to the bizarre humming on Nov. 11, 2018 when a New Zealand geologist <a href="https://twitter.com/matarikipax/status/1061590953876582402?s=20" target="_blank">tweeted</a>, "This is a most odd and unusual seismic signal. Recorded at Kilima Mbogo, Kenya ..." with a link to data from the U.S. Geological Survey, as as <a href="https://www.washingtonpost.com/nation/2020/01/09/earthquake-creates-underwater-volcano/" target="_blank">The Washington Post</a> reported.</p><p>That led to a worldwide effort by seismologists to pinpoint the source of the low frequency humming. A team of German scientists took on the task of recreating what happened that led to the formation of a brand new volcano.</p>
<p>This is "the first time we've really observed the birth of a volcano on the sea floor," said Simone Cesca, a seismologist at the GFZ German Research Center for Geosciences in Potsdam, Germany and the paper's lead author, to <a href="https://www.washingtonpost.com/nation/2020/01/09/earthquake-creates-underwater-volcano/" target="_blank">The Washington Post</a>.</p><p>The paper explains how magma from a reservoir buried about 20 miles under the <a href="http://www.ecowatch.com/tag/oceans" target="_self">ocean</a> floor migrated upward from the earth's mantle and pushed itself through the earth's crust. Once it breached the ocean floor, the magma could flow through the opening and create a new volcano, as <a href="https://www.cnn.com/2020/01/09/world/seismic-hum-volcano-scn-trnd/index.html" target="_blank">CNN</a> reported.</p><p>"It took only [a] few weeks for the magma to propagate from the upper mantle to the seafloor, where a new submarine volcano was born," said Cesca in an email to <a href="https://www.livescience.com/underwater-volcano-hum.html" target="_blank">Live Science</a>.</p><p>The scientists traced 7,000 tectonic quakes during the study. Tectonic quakes happen when Earth's tectonic plates get stuck as they move alongside one another and pressure builds for them to move, which causes an earthquake, as <a href="https://www.cnn.com/2020/01/09/world/seismic-hum-volcano-scn-trnd/index.html" target="_blank">CNN</a> reported.</p><p>The seismologists also recorded 407 unusual signals coming from the site of the magma chamber near Mayotte. Those unusual signals, called Very Long Period signals, are the low humming that is similar to a double bass or the peel of a large bell, according to <a href="https://www.cnn.com/2020/01/09/world/seismic-hum-volcano-scn-trnd/index.html" target="_blank">CNN</a>. The Very Long Period signals last 20 to 30 minutes and can be detected hundreds of miles away.</p>
<p>Without the Very Long Period signal that hummed so dramatically on Nov. 11, seismologists probably would not have discovered the underwater volcano, said Stephen P. Hicks, who studies earthquake seismology at the Imperial College of London and who is unrelated to the team of Mayotte researchers, to <a href="https://www.washingtonpost.com/nation/2020/01/09/earthquake-creates-underwater-volcano/" target="_blank">The Washington Post</a>.</p><p>A "unique aspect of this study is it shows how quickly the magma can rise and create either a new volcano or an eruption," said Hicks. "This paper gives us a framework to interpret these seismic events. The amount of magma that moved might have been the greatest amount ever observed."</p><p>The new volcano is three miles in diameter and half a mile from the sea floor. During the formation of the underwater volcano, earthquake activity dropped, and the ground of Mayotte lowered seven inches, though it was hardly noticeable on Mayotte, which is home to about 260,000 people, as <a href="https://www.cnn.com/2020/01/09/world/seismic-hum-volcano-scn-trnd/index.html" target="_blank">CNN</a> reported.</p><p>"Since the seabed lies 3 kilometres below the water surface, almost nobody noticed the enormous eruption," said Torsten Dahm, study co-author and professor of geophysics and seismology at the University of Potsdam in Germany, as <a href="https://www.cnn.com/2020/01/09/world/seismic-hum-volcano-scn-trnd/index.html" target="_blank">CNN</a> reported. "However, there are still possible hazards for the island of Mayotte today, as the earth's crust above the deep reservoir could continue to collapse, triggering stronger earthquakes."</p>

A powerful 6.4-magnitude earthquake struck Puerto Rico just before dawn on Tuesday after a week of heavy seismic activity. The early morning quake caused power plants to shut down to protect themselves, leaving the island in a blackout until power is restored later in the day. It also killed at least one person, injured at least eight and collapsed buildings, as the AP reported.
<p>The quake struck at 4:24 a.m. (3:24 a.m. ET), with its epicenter just off Puerto Rico's southern coast, about 6 miles south of Indios town, according to the <a href="https://earthquake.usgs.gov/earthquakes/eventpage/us70006vll" target="_blank">U.S. Geological Survey</a>, as <a href="https://www.cnn.com/2020/01/07/us/puerto-rico-earthquake-tuesday/index.html" target="_blank">CNN</a> reported. The quake triggered three strong aftershocks with preliminary estimates of 5.6, 5.2 and 4.5 magnitude. A bit later a 5.8-magnitude temblor hit closer to Indios at 7:18 a.m., according to the <a href="https://earthquake.usgs.gov/earthquakes/eventpage/us70006vll" target="_blank">U.S. Geological Survey</a>.</p><p>The quake follows a 10-day series of temblors spawned by the grinding of tectonic plates along three faults beneath southern Puerto Rico. Seismologists are unable to predict when the quakes will stop or if they will continue and get stronger, according to the <a href="https://apnews.com/e2ec8e9bd12aea8aff6b240976897389" target="_blank">AP</a>.</p><p>Tuesday's quake was the strongest to hit the island since the temblors began on Dec. 28. It killed Nelson Martínez Guillén, 73, who died after a wall fell on him in the city of Ponce, Mayor Mayita Meléndez said. Another woman had a broken leg after she was pinned under a wall, as <a href="https://www.nytimes.com/2020/01/07/us/puerto-rico-earthquake.html?action=click&module=Latest&pgtype=Homepage" target="_blank">The New York Times</a> reported.</p><p>"The people are scared," Ms. Meléndez said, according to <a href="https://www.nytimes.com/2020/01/07/us/puerto-rico-earthquake.html?action=click&module=Latest&pgtype=Homepage" target="_blank">The New York Times</a>. "There are homes that are totally destroyed."</p><p>She added that the tremors moving through the area have people near the beach living in fear of tsunamis and desperate to flee their homes. However, the United States National Tsunami Warning Center <a href="https://twitter.com/NWS_PTWC/status/1214464205635457024" target="_blank">wrote on Twitter</a> that there was no related tsunami threat.</p><p>"It's not safe," Ms. Melendez said, as <a href="https://www.nytimes.com/2020/01/07/us/puerto-rico-earthquake.html?action=click&module=Latest&pgtype=Homepage" target="_blank">The New York Times</a> reported. "The earth is moving constantly."</p><p>Govenor Wanda Vázquez ordered government offices to remain closed Tuesday except for employees working in an emergency capacity, as the <a href="https://www.miamiherald.com/news/nation-world/world/americas/article239025058.html" target="_blank">Miami Herald</a> reported.</p><p>"It's important for the people of Puerto Rico to remain calm and to secure their lives and property," she said in a statement, according to the <a href="https://www.miamiherald.com/news/nation-world/world/americas/article239025058.html" target="_blank">Miami Herald</a>. "Citizen security is a priority for me, so we are inspecting vulnerable areas and we're taking all the measures necessary to guarantee the safety of Puerto Ricans."</p><p>Local news on Puerto Rico's southern coast reported that several houses collapsed on the coastline and a local highway was shutdown due to rock fall.

Over the past decade, climate-fueled disasters drove over 20 million people a year from their homes, concluded a report released by Oxfam on Monday. The Oxfam study, titled "Forced from Home," was released as two weeks of UN climate negotiations kick-start in Madrid.
<p>It examined the numbers of <a href="http://www.ecowatch.com/tag/climate-refugees">people displaced</a> inside their home countries by climate-fueled disasters between 2008 and 2018, based on government and international agency data, as well as media reports.</p><p>"Today people are seven times more likely to be internally displaced by cyclones, <a href="http://www.ecowatch.com/tag/flooding">floods</a> and <a href="http://www.ecowatch.com/tag/wildfires">wildfires</a> as they are by <a href="http://www.ecowatch.com/tag/earthquakes">earthquakes</a> and volcanic eruptions, and three times more likely than by conflict," the report said.</p><p>While no one is immune, people in <a href="https://www.dw.com/en/building-walls-to-keep-climate-refugees-out/a-48273469" target="_blank">poor countries are most at risk</a>, the NGO said. "People in low and lower-middle income countries such as India, Nigeria and Bolivia are over four times more likely to be displaced by <a href="http://www.ecowatch.com/tag/extreme-weather">extreme weather</a> disasters than people in rich countries such as the United States."</p>
<p>Seven of the top 10 countries with the highest displacement by proportion of their population were <a href="https://www.dw.com/en/climate-change-drives-solomon-islands-people-of-the-sea-ashore/a-40777201" target="_blank">small island developing states, largely in the Pacific</a> and the Caribbean, the report found.</p><p>Asia is the continent most affected, said Oxfam, noting that around 80% of all people displaced over the last decade live there.</p><p>"Our governments are fueling a crisis that is driving millions of women, men and children from their homes and the poorest people in the poorest countries are paying the heaviest price," said Chema Vera, Acting Executive Director of Oxfam International.</p>
<h2>Costs Rising Quickly</h2><p>Overall, the number of <a href="https://www.dw.com/en/coping-with-climate-anxiety-on-a-warming-planet/a-51198686" target="_blank">weather disasters considered extreme</a> grew five-fold over the last decade, researchers said.</p><p>As more people leave their homes as a result of weather disasters, costs — and threats to social stability — are rising quickly for the countries trying to manage that displacement, often with few resources, the report said.</p><p>At the UN climate talks in Madrid, environmental and development groups are pushing to establish a fund to help countries already reeling from climate-enhanced heat waves, droughts, floods and storms made worse by wilder weather and <a href="http://www.ecowatch.com/tag/sea-level-rise" target="_self">rising seas</a>.</p><p>Poor and vulnerable nations are set to receive $100 billion annually from next year to prepare for future impacts, but no concrete provisions exist yet for "loss and damage" already incurred.</p>
