The USGS, established in 1879, monitors and analyzes Earth’s systems, providing data to protect lives and property. The agency currently lists volcanoes Great Sitkin and Shishaldin as being under an Orange Watch and Yellow Advisory, respectively, as of February 20, 2026. Kilauea volcano is also under an Orange Watch, and Ahyi Seamount is under a Yellow Advisory.

The earthquake in Puerto Rico follows a series of seismic events recorded globally in the preceding weeks. On February 14, 2026, a magnitude 6.4 earthquake was detected 53 kilometers west-northwest of Port-Olry, Vanuatu. A magnitude 6.2 earthquake struck 32 kilometers southwest of Ovalle, Chile, on February 12, 2026. Smaller magnitude earthquakes were also recorded in Alaska and other regions.

The USGS provides real-time earthquake information through its Latest Earthquakes application and an interactive map. The agency also offers the ShakeAlert system, designed to provide seconds of warning before strong shaking begins. The system sends notifications to mobile phones and emergency systems.

According to the USGS, areas with the highest seismic risk in the United States include California, Alaska, Hawaii, Nevada, Texas, New York, New Jersey, and the Washington D.C. Metropolitan area. The agency emphasizes the importance of preparedness, recommending that individuals develop family emergency plans, identify safe zones within their homes, and assemble emergency kits with essential supplies.

The USGS advises individuals during an earthquake to remain calm, drop to the ground, take cover under sturdy furniture, and hold on. Those outdoors should move away from buildings, power lines, and other potential hazards. Following an earthquake, individuals should check for injuries, assess structural damage, and stay informed through official channels.

Currently, there is no technology capable of predicting the exact time or location of an earthquake, but continuous monitoring helps to understand patterns of activity in different regions. Updated reports and information are available on the USGS website, earthquake.usgs.gov.
