Double trouble: Volcanic eruption leads to strong earthquake eight months later


 In January 2002, Nyiragongo Volcano erupted in the Democratic Republic of the Congo, killing more than 100 people. Eight months later and 19 kilometers to the south, a magnitude-6.2 earthquake shook the Lake Kivu region, partially destroying the town of Kalehe. Now, scientists have determined that the two events were linked, and their results highlight a newly observed trigger for strong earthquakes near active volcanoes.

“When you have two events strike the same area within a few months of each other, you have to wonder if they’re linked in some way,” says Christelle Wauthier, a geophysicist at Penn State University and lead author of the new study published in Geochemistry, Geophysics, Geosystems.  More
