V-shaped topographic basins radiating from central Antarctica could be remnants of of the continent's deep geologic history.

Is the Pioneer Fragment really stuck to the Pacific plate beneath a part of North America that’s extremely seismically active?

Seismic data show how Alaska's Columbia Glacier launches icebergs into the sea.

Seismic imaging below the San Francisco Volcanic Field in Northern Arizona provides clues about the history of eruptions there.

Knowing how much the ground will shake requires a good model of seismic velocity.

Comparing seismic data and drone imagery near a churning lava lake shows the signal of bursting bubbles.

Model catalogs quarry blasts, heavy machinery noise, and other anthropogenic signals that can muddy seismic data.

No single map of sediment thickness across the conterminous U.S. existed that used a consistent method — until this new one based on Transportable Array seismic data.

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.

In the first week of October in 2023, earthquakes struck in a cluster near submarine volcanoes off Japan, producing a tsunami.

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.

Could a set of local railroad ghost stories be related to small, understudied earthquakes?

Seismic imaging can map out hidden weaknesses around salt caverns used to store oil and gas.

Distinguishing between intermittent unrest and an eruption’s prologue poses a major challenge to volcanologists responsible for forecasting earthquake activity. A recent eruption of Mauna Loa, Hawai’i provided scientists a unique opportunity to tackle this problem.

A set of studies explores questions pertaining to the rotation of the inner core relative to Earth’s mantle.

In East Greenland, a mysterious tsunami hit a military base on a remote island tucked into the fjords. At the same time, seismologists noticed a weird signal on seismic stations located around the world.

When seismic sensors aren't detecting earthquakes, they’re picking up other vibrations—even shakes too subtle for people to feel. This ambient seismic noise might be able to tell scientists what’s happening at Mount St. Helens during times of activity and purported respite.

Yale scientists discuss how to incorporate a low-cost, education-ready seismic sensor with coursework and outreach.

Different forces are tearing the western U.S. apart. Which ones are most important?

In Western Antarctica, the Pine Island Glacier ice shelf cracks and calves. One of these rifting events was observed via seismic sensors, demonstrating that while the tear was slower than expected, it’s still the fastest through-cutting fracture in a floating ice shelf ever recorded.
