A new Trump administration protocol requires U.S. Geological Survey (USGS) scientists to run interview requests with the Department of the Interior, its parent agency, before speaking to journalists, the Los Angeles Times reported.
The move is a departure from past media practices that allowed government scientists to quickly respond to journalists' inquiries, according to unnamed USGS employees interviewed by the Times.
After decades of bitter struggle, the Arctic National Wildlife Refuge (ANWR) seems on the verge of being opened to the oil industry. The consensus tax bill Republicans are trying to pass retains this measure, which was added to gain the key vote of Alaska Sen. Lisa Murkowski.

A magnitude 5.0 earthquake struck Oklahoma Sunday night, damaging buildings in the heart of the oil hub town of Cushing. Schools are closed and parts of the downtown area are cordoned off, as the latest in a string of 19 quakes were recorded in Oklahoma last week, an area where such events were virtually unknown prior to the fracking boom.

Bricks and concrete crashed down as windows shattered and residents were rattled at 7:44 p.m. local time. At least one senior living complex was evacuated. Cushing city officials have told people to stay out of the downtown area.
Bloomberg reported this morning that some gas leaks have occurred, but they have been contained. As a precaution, All companies that run intra-state pipelines that fall under the jurisdiction of the Oklahoma Corporation Commission have shut down operations.
The quake was felt as far as Illinois, Kansas, Missouri, Arkansas and Texas.
Oklahoma has become the world capital of earthquakes. In neighboring Kansas, injection of wastewater from fracking was determined as the cause of the state's largest-ever earthquake in 2014. A study published in Science determined a link between wastewater injection and earthquakes in Texas. And earlier this year, a study confirmed a causal relationship not only between wastewater injection and fracking, but to the process of hydraulic fracturing itself.

Cushing, a town of 7,900 that calls itself the Pipeline Crossroads of the World, is home to one of the largest oil storage terminals on the planet, and reported 58.4 million barrels of oil in its tanks as of last month. As of this morning, no damage has been reported to either pipelines or the oil storage facility.
But damaged pipelines as a result of earthquakes have happened. In December 2013, an earthquake ruptured a gas pipeline in the Russian city of Sochi, site of the 2014 Winter Olympic games. The 1971 San Fernando earthquake in California damaged water, gas and sewage pipelines. Other earthquakes have caused failures in pipelines in China, Japan and the U.S.
In a paper by Teoman Ariman of the University of Tulsa, Oklahoma, he wrote, "The type of severity of pipeline damage in earthquakes are directly related to the patterns of ground movements which can be due to faulting, soil liquefaction, landslides and compaction." Ariman also noted that "steel pipelines withstood ground shaking but were unable to resist the large permanent ground deformations generated by faulting and ground failures."
As daylight broke, the full extent of the damage in Cushing was being evaluated.

Is the San Andreas Fault about to unleash The Big One? Southern Californians were on heightened alert this week after a swarm of small quakes in the Salton Sea near the fault triggered officials to issue an earthquake alert for residents in the area.

The swarm began just after 4 a.m. on Sept. 26, starting earthquakes three to seven miles deep underneath the Salton Sea, The Los Angeles Times reported. The biggest earthquakes hit later that morning—a 4.3—and then a pair later at night, another 4.3 followed by a 4.1. There was another burst of activity the following night. The U.S. Geological Survey (USGS) said 96 earthquakes above magnitude 2 were reported by Sept. 30.
This is only the third time this area has seen a swarm like this since earthquake sensors were installed in 1932, and it had more earthquakes in it than swarms in 2001 and 2009, LiveScience said.

Based on this activity, on Sept. 27, the USGS said the risk of an earthquake of magnitude 7.0 or greater in Southern California increased to between 1 in 3,000 and 1 in 100 over the the next seven days. However, as of Friday, Sept. 30, the likelihood was decreasing.
"Preliminary calculations indicate that … there is 0.006% to 0.2% chance (less than 1 in 10,000 to 1 in 500) of a magnitude 7 or greater earthquake being triggered on the southern San Andreas Fault within the next seven days through Oct. 7," the updated warning said. "These revised probabilities are lower than those made earlier this week, due to decreasing swarm activity."
The average chance for such an earthquake striking on any given week is 1 in 6,000.

The risk assessment from USGS prompted California Gov. Jerry Brown to sign legislation Sept. 29 ordering the development of a statewide warning system that would inform Californians of impending earthquakes through their cellphones, radios and other devices, the Associated Press reported.
San Bernardino, which is on the San Andreas Fault, even closed down city hall through today over concerns about how the structure would fare in a big quake. A 2007 report revealed how the building, constructed in 1971, was not built to withstand a major earthquake and would cost about $20 million to get retrofitted for such an event.
"We haven't had an alert like this," Mark Scott, San Bernardino's city manager, told the Los Angeles Times. "We're not trying to suggest that the alert is an impending catastrophe. We're just trying to use an abundance of caution. We care about the safety of the public and our employees."
The city already has plans to vacate the building within the next few months.
Scientists estimate that the last time the San Andreas Fault's southernmost stretch ruptured was in 1680—more than 330 years ago. A big earthquake happens on average in this area once every 150 or 200 years, making the region long overdue for a major quake. The largest historical earthquakes that occurred along the fault were those in 1857 and 1906.

The area where this recent swarm occurred was near a set of north-northeast trending cross-faults beneath the Salton Sea, some which are oriented as such that they would add stress to the San Andreas Fault and the San Jacinto Fault system, according to USGS. However, the agency said swarm-like activity in this region has occurred in the past, so this week's activity, in and of itself, is not necessarily cause for alarm.
While this news is somewhat reassuring, residents in Southern California shouldn't breathe too big a sigh of relief, Morgan Page, a research geophysicist with the USGS in Pasadena, told LiveScience.
"We live in earthquake country and we should be prepared for an earthquake at any time," Page said. "Events like this can change the probabilities from week to week but it never goes to zero."
