About this earthquake

On October 5, 2026 at 10:52 UTC, a magnitude M5.0 earthquake occurred near 187 km ENE of Saipan, Northern Mariana Islands. With a focal depth of about 10 km, this was a shallow earthquake, whose shaking is usually felt more strongly at the surface. Events of this size can cause damage near the epicenter.

The data is provided by USGS and cross-checked across seismological networks.

Why depth matters

Shallow quakes release energy near the surface — shaking is felt more strongly and damage potential is higher.

Official USGS aftershock forecast

Probability of at least one aftershock at or above the specified magnitude during the entire stated time window. This does not predict an individual earthquake.
