Moderate M 5.3 Earthquake Strikes Pagan Region, Northern Mariana Islands

What Happened

A moderate earthquake with a magnitude of 5.3 (mb) was recorded in the Pagan region of the Northern Mariana Islands. The seismic event occurred on March 2, 2026, at 14:38:22 UTC. The event has been reviewed by seismologists at the USGS.

Location Details

The earthquake was centered at coordinates 18.8779°N and 145.6537°E. It originated at a depth of 191.3 km. This is classified as a deep earthquake, as it occurred significantly below the 70 km threshold. Deep earthquakes typically result in less intense shaking at the surface compared to shallow events of the same magnitude.

Impact Assessment

According to the USGS data, there was no tsunami advisory, watch, or threat issued in connection with this event. There are currently no felt reports submitted by the public, and no specific alert level color has been assigned. Due to the depth and location, the immediate impact is expected to be minimal.

What You Should Know

A magnitude 5.3 event is categorized as a moderate earthquake. While earthquakes of this size can cause damage to poorly constructed buildings when they occur at shallow depths, the 191.3 km depth of this event likely mitigated surface effects. Residents in the region should always be prepared for the possibility of aftershocks, which are routine following seismic activity of this magnitude.
