Earthquake Early Warning: Vital for City Transit

Although no one can reliably predict earthquakes, today’s technology is advanced enough to rapidly detect seismic waves as an earthquake begins, calculate the maximum expected shaking, and send alerts to surrounding areas before damage can occur. This technology is known as “earthquake early warning” (EEW).

Fewer Large Earthquakes in 2014

While the number of large earthquakes fell to 12 in 2014, from 19 in 2013, several moderate temblors hit areas relatively new to seismicity, including Oklahoma and Kansas, according to the U.S. Geological Survey. Worldwide, 11 earthquakes reached magnitude 7.0-7.9 and one registered magnitude 8.2, in Iquique, Chile, on April 1.

New Sensor Network to Detail Virginia Earthquakes

Scientists from the U.S. Geological Survey and Virginia Tech will install a 20-station seismic network in the central Virginia area beginning Jan. 8. The new sensors – each about the size of a soda can – will provide information to help the researchers study the background seismicity in the area and any continuing aftershocks of the Aug. 23, 2011 earthquake near Louisa and Mineral, Va.
