There are tantalizing hints some faults issue warning signals in the days and months before a big earthquake, according to new research.
A study of squeaky glass beads squeezed between powerful pistons offers one explanation for how these earthquake warning signals form. The findings were published online Nov. 4 in the journal Geophysical Research Letters.
WASHINGTON, D.C. - We are excited to be featured at the National Building Museum multimedia exhibition, Designing for Disaster, a call-to-action for citizens from design professionals and local decision makers to homeowners and school children, to prepare for unexpected events. The exhibition opened May 11, 2014 and continues through August 2, 2015. Continue reading
(CNN) – Strict building codes and the preparedness of millions of Chileans who live along an arc of volcanoes and fault lines likely kept the death toll — only six by Wednesday afternoon — low after an 8.2-magnitude earthquake rumbled offshore and prompted a tsunami, observers said.
Officials said four of those whose deaths were blamed on the quake late Tuesday that triggered landslides, power outages, and a tsunami suffered heart attacks, while two others were crushed.
“They’re a seismically active region of the world and they are very good at implementing their building codes similar to California,” John Bellini, a Denver-based geophysicist at the U.S. Geological Survey told CNN on Wednesday. Continue reading
(CNN) – A mighty 8.2-magnitude earthquake struck off the coast of northern Chile late Tuesday, triggering small landslides, cutting power and generating a tsunami.
Four men and one woman died — two who suffered heart attacks and three who were crushed, said Interior Minister Rodrigo Penailillo. Continue reading
Chile’s northern coast has been hit by more than 300 earthquakes in the past week in what seismologists warned Tuesday could be the precursor to a long-overdue disaster. Most of these quakes have been too small to be felt on land, but people living near the city of Iquique have experienced the rumbling of up to a dozen tremors per day.
