Volcanoes tend to have seismicity that waxes and wanes over time. That’s considered normal and not necessarily a cause for concern. Let’s check on Mount Adams to see what USGS scientists are doing to learn more about its recent earthquake activity and what it could mean for this Cascade Range volcano.

Explained: The December 5th, 2024 Earthquake (AD)
USGS Scientist, Bob deGroot, briefly explains what happened during the magnitude 7.0 earthquake that occurred offshore of Mendocino, CA, on December 5, 2024.
The event occurred in an area called the Triple Junction, where the Pacific, Juan de Fruca, and North American tectonic plates meet.

Hydrothermal Explosions — more common than you think! (Yellowstone Monthly Update - Dec 2024)
The hydrothermal explosion in Biscuit Basin stole all the headlines. But did you know there was a smaller hydrothermal explosion in Norris Geyser Basin on April 15, 2024? That explosion was detected by a new infrasound sensor installed this past September. Watch to learn more.

(Some) Assembly Required: HT Sign up for Great ShakeOut
Did you feel that?
The annual Great ShakeOut Earthquake Drill is coming on Thursday, Oct. 17, 2024, at 10:17 a.m. (local time, wherever you are). We never know where or when an earthquake may happen, but preparing is easier than assembling a piece of Scandinavian furniture.
Don’t believe us? Take a look at this step-by-step guide.

Nuvuk video camera 2 dark image
Two video cameras are installed atop a utility pole near the northernmost point of land in the United States at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes.
