Seismic risk in eastern Mediterranean higher than previously estimated
The eastern Mediterranean is more seismically active than previously assumed, a new study finds. On a geological time scale, seismic activity around the island of Crete has generated large earthquakes in bursts, potentially increasing the future risk for earthquakes and tsunamis in the region.

New research calls for rethinking of New Zealand’s Alpine Fault
New research could prompt a shift in thinking about New Zealand’s Alpine Fault.

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.

Earthquake faults identified in surge of Oklahoma quakes
New research has revealed the faults associated with more than 3,600 earthquakes that have been recorded in Oklahoma since 2009. The study also finds that recently reactivated ancient faults in the center of the state could generate higher-magnitude and more destructive earthquakes than the region has experienced since earthquake activity picked up there five years ago.

Up close and personal with a volcanic eruption
Thorbjorg Agustsdottir, a Ph.D. student studying seismology at the University of Cambridge, had the rare opportunity to witness a volcanic eruption up close when Iceland’s Bardarbunda volcano erupted while she and fellow researchers were servicing seismometer stations around the volcano.

Seismic gap may be filled by an earthquake near Istanbul
When a segment of a major fault line goes quiet, it can mean one of two things: The “seismic gap” may simply be inactive — the result of two tectonic plates placidly gliding past each other — or the segment may be a source of potential earthquakes, quietly building tension over decades until an inevitable seismic release.
A new study published in Geophysical Research Letters, a journal of the American Geophysical Union, has found evidence for both types of behavior on different segments of the North Anatolian Fault — one of the most energetic earthquake zones in the world.
