Advancing earthquake science worldwide
5 February 2026—The magnitude 6.9 earthquake that took place in 2018 on the south flank of Kīlauea on the Island of Hawaiʻi may have stalled episodes of periodic slow slip along a major fault underlying the volcano, according to a new study by scientists at the U.S. Geological Survey. Since … Continue Reading »
3 February 2026—A swarm of small earthquakes within the Karoo Basin in South Africa has revealed a critically stressed fault that could be perturbed by potential shale gas exploration in the area, according to a new report in Seismological Research Letters. The analysis by Benjamin Whitehead of the University of … Continue Reading »
22 January 2026—For decades, researchers thought that an October 1843 earthquake on the small Greek island of Chalke caused a powerful tsunami and led to the deaths of as many as 600 people. But a new analysis of primary accounts of the event by Ioanna Triantafyllou at Hellenic Mediterranean University … Continue Reading »
2 December 2025—Since 2020, the Barry Landslide in Alaska’s Prince William Sound has been outfitted with instruments monitoring seismic signals from the area, as researchers hope to catch a destructive, tsunami-generating landslide before it starts. A team of scientists studying those signals have identified an unusual class of seismic events, … Continue Reading »
26 November 2025—A satellite deployed to measure ocean surface heights was up to the challenge when a massive earthquake off the Kamchatka Peninsula triggered a Pacific-wide tsunami in late July. The Surface Water Ocean Topography or SWOT satellite captured the first high-resolution spaceborne track of a great subduction zone tsunami, … Continue Reading »
18 November 2025—An array of seismic sensors deployed to capture aftershocks from the 2018 magnitude 7.1 Anchorage earthquake also collected distinctive signals from hundreds of flights crossing over Alaska. In their study published in The Seismic Record, Isabella Seppi and colleagues at the University of Alaska Fairbanks show that these … Continue Reading »
