3-D maps illustrate formation of the Hangai Dome in central Mongolia

Researchers at Rice University, the University of Toronto, and Princeton University generated 3-D maps of the Earth under the Hangai Dome in central Mongolia from seismic data. The 3-D image below shows the earth under the dome. Colored yellow, warm rock rises up from the deep mantle toward the Earth’s surface. The pressure on the rock drops as it rises. When the rock reaches 150 kilometers (93 miles) below the surface, it starts to melt and form magma, illustrated in red. Heat released by the magma modifies the rigid outer layer of the Earth that becomes lighter and rises up, creating the Hangai Dome.

Wake-up call from the Hayward Fault

During a brief visit to California this week, I, along with a metroregionfull of people, was treated to a rattling little temblor from the Hayward Fault. The quick jolt struck conveniently just before everyone’s morning alarms went off, serving as a wakeup call for the day, and as this season’s broader “wakeup call” reminder that there are big active seams in the crust inching along around and below our cities. …

16th century Italian earthquake changed river’s course

In 1570, a 5.8-magnitude earthquake struck the northern Italian city of Ferrara, causing dozens of deaths, major damage to the city and thousands to flee. At the time, Pope Pius V said God sent the earthquake to punish the city’s duke who had given hospitality to Jews and Marranos who had escaped Spain.

Now, a new study finds that the 16th century earthquake and subsequent aftershocks were the last step in a tectonic process that occurred over thousands of years and changed the course of the Po River. The final rerouting of the river left Ferrara dry by the end of the 16th century, an event depicted in a painting that now hangs in the Vatican Museum.

Views of strong shaking in Nepal and what they teach us

When the ground shook throughout Nepal in April, it was neither predicted nor surprising–the paradox of inevitable but chaotic large earthquakes within well known seismic zones. Though warnings of Nepal’s catasrophic earthquake risk have been sounded for years, and though this magnitude 7.8 and its energetic 7.3 aftershock wrought plenty of death, destruction, and tragedy, scientists are finding themselves somewhat surprised at the apparently rather limited degree of overall damage …

It’s 2015. We respond to earthquakes from space.

The seismic waves ringing out from Nepal on April 25 reached sensors around the planet, mobilizing a vast, remote response that’s truly a sign of the times in modern seismic disaster recovery. While Kathmandu and the surrounding towns and villages stood shocked and crippled by the now-named Gorkha earthquake, satellites sweeping by overhead quickly gathered a picture of the scene, transmitting intricate detail of the disaster to the world with …
