16 December 2020–Big earthquakes may grab the headlines, but for Takahiko Uchide, the small events are just as interesting. For one thing, studying small earthquakes is a good way to learn about the physical properties of underground faults at a fine scale, he says. “Earthquakes reflect factors including the applied … Continue Reading »
9 December 2020–The summer 2018 eruption of Kīlauea Volcano on the Island of Hawai’i was one of the most significant in the volcano’s history, collapsing a large portion of the summit caldera, erupting massively from its flank and triggering a magnitude 6.9 earthquake in the process. Through it all, scientists … Continue Reading »

1 December 2020–A rupture along the full length of the fast-slipping Alpine Fault on New Zealand’s South Island poses the largest potential seismic threat to the southern and central parts of the country. But new evidence of a 19th century earthquake indicates that in at least one portion of the … Continue Reading »
16 November 2020–Costa Rica is home to about 15,000 earthquakes a year, and its citizens are well-educated when it comes to the science behind all the seismic activity, says Esteban Chaves. “If you ask a Costa Rican where the subduction zone is, they are able to respond. Most of them … Continue Reading »
4 November 2020–An earthquake of magnitude 8.0 or larger will almost always cause strong shaking, but a new study suggests that smaller earthquakes—those around magnitude 5.5 or so–are the cause of most occurrences of strong shaking at a 60-kilometer (37-mile) distance. Small earthquakes are expected to produce relatively weak shaking, … Continue Reading »
