This location map and inset maps of the National Seismic Hazard Model (NSHM) show areas of interest for the populated Pacific Territories of the United States. The inset maps highlight Guam and the Commonwealth of the Northern Mariana Islands (GNMI) and American Samoa (AmSam), two large regions assessed for seismic hazards in the NSHM of 2027.

The starting view is from January, 1970, a field photo of Punta Ventana (“Window Point”) at Guayanilla, Puerto Rico (Monroe, 1980). The image fades to the March 5, 2020 color photo of the same location (ten Brink, 2020). The natural arch had collapsed from earthquake shaking on January 6, 2020 during the 2020 Southwest Puerto Rico Earthquake Sequence.

10 Largest Earthquakes Ever Recorded (Updated 2025)
#10. MAGNITUDE 8.6 (1950). Arunachal Pradesh, India - Referred to as the Assam-Tibet earthquake, this quake produced intense shaking, triggered sandblows, ground cracks, and large landslides across the region. All told, 780 people died.

Computer simulation of shaking during the April 14, 2025 M5.2 Julian, CA earthquake. As the waves propagate away from the epicenter they interact with different geologic materials, which can slow down and amplify the shaking.

Ammonia or ammonium? What’s the difference? In water, ammonia (NH3) and ammonium (NH4+) exist together in an equilibrium that depends on pH and temperature. As the temperature or pH rise, ammonia (NH3) becomes more abundant. This is important because ammonia is more toxic than ammonium.

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 Fuca, and North American tectonic plates meet.
