2.2-magnitude earthquake shakes Irving.

GREENFIELD (KCBS) — A earthquake registering a preliminary magnitude of 4.4 struck along the San Andreas Fault near Greenfield in Monterey County on Tuesday, according to the U.S. The quake comes days after hundreds of residents packed Irving City Hall to hear SMU seismologists discuss the more than three dozen earthquakes that have hit in or near Irving since April.OKLAHOMA CITY (AP) – After increasing rapidly over the past three years, the pace of earthquakes in Oklahoma held steady in 2014 at a rate higher than California and far higher than the historic average in Oklahoma. At Thursday’s meeting seismologist Brian Stump said a team has placed 22 seismometers around Irving, which should provide better data on North Texas earthquakes. Deeper quakes are less noticeable while a shallow quake–in the 0 to 40 mile depth range–can feel much stronger than their actual reported magnitude.

The number is up from about 2 percent in 2011 and outpaces California, where about 10 percent of residents have earthquake insurance. “We’re continuing to get more and more inquiries,” Doak said. “Gov. This article will be updated as information warrants, and follow KPIX 5 on Twitter at @CBSSF or KCBS Radio on Twitter at @KCBSNews for updates on breaking news anytime.

Fallin and I have worked together to ensure insurance agents throughout the state now have one hour of continuing education dedicated to earthquake insurance. Now licensed brokers are talking about it, and they’re going back and learning about the policies.” “Earthquake insurance is affordable and accessible, but you need to understand the terms and conditions in the policy,” he said. “Each policy has different factors. Some things are covered and others are not covered.” Part of the problem of seeking to determine a cause of the increased activity is that existing earthquake models are based on naturally occurring earthquakes and do not include induced seismically. Researchers still are trying to determine whether or to what extent man-made activity is contributing to the state’s seismic activity. “There have been occurrences not just in the state, but across the country, where we’ve seen induced seismology,” Teague said. “We’ve seen correlations with injection wells in Ohio and Arkansas, but we haven’t seen that tight correlation in Oklahoma.

That’s absolutely one of the struggles.” Some studies have connected earthquake activity in Oklahoma and other parts of the country to water injection wells used to dispose of water produced along with oil and natural gas.
