The USArray project was a “think big” moment for seismology
Between 2004 and 2021, seismometers were deployed in more than 2,000 locations as part of the USArray.
Seismic imaging detects changes beneath volcano outside Taipei
The Tatun Volcano Group rises near the Taipei metropolitan area — home to more than 7 million people. Though no record exists of eruptions in human history, recent seismicity indicates that these volcanoes might be growing restive.
Seismic data show what’s driving an Ethiopian geothermal field
The Aluto volcanic complex is Ethiopia’s only geothermal site. Microseismicity reveals volcanic structure and seasonality of earthquakes.
What’s inside the Moon? Seismology can show us
A series of Apollo missions put seismometers on the Moon, allowing us to learn a lot about our neighbor’s interior.
Quite accomplished for a 22-year-old: celebrating the Network of the Americas
It’s been 22 years since the NSF first funded an ambitious project to build a large-scale geodetic network we now know as the Network of the Americas. As the NSF GAGE facility award reaches its end, it’s worth looking back at how we got here.
As Arctic sea ice declines, seismometers hear waves beating on unprotected shores
Seismic noise can serve as an indicator of wave action and sea ice coverage offshore.
An unusual tsunami in Japan looks to have been caused by a submarine caldera
In the first week of October in 2023, earthquakes struck in a cluster near submarine volcanoes off Japan, producing a tsunami.
Golden Triangle temblors reveal thickness of earthquake-prone crust
A recent study of the hidden seismic hazards within the Golden Triangle region of Laos, Thailand and Myanmar found new faults and interesting patterns in the depths of the fault motion.
Radar reveals a Greenland glacier’s daily balancing act
Terrestrial Radar Interferometry can help detect how rising sea levels put pressure on Greenland’s Helheim Glacier.
Ghosts and swarms put spotlight on seismicity in South Carolina
Could a set of local railroad ghost stories be related to small, understudied earthquakes?
