Magnitude 4.9 Earthquake Recorded South-Southwest of Tambolaka, Indonesia

What Happened

A light earthquake with a magnitude of 4.9 mb was recorded on February 15, 2026, at 13:44 UTC. The seismic event was centered approximately 266 km south-southwest of Tambolaka, Indonesia. According to the U.S. Geological Survey (USGS), the earthquake occurred at a shallow depth of 10 kilometers.

Location Details

The earthquake’s epicenter was located at coordinates 11.4831°S and 117.9622°E. The recorded depth of 10 km is considered shallow (less than 20 km). Shallow earthquakes are typically felt more strongly than deeper ones, though the impact of this event is influenced by its distance from the coastline.

Impact Assessment

Based on the available data, there is no tsunami advisory, watch, or warning in effect. No felt reports have been submitted to the USGS regarding this event, and no specific alert level color has been assigned. Due to the magnitude and the offshore location, significant damage to populated areas is unlikely.

What You Should Know

A magnitude 4.9 earthquake is classified as a “light” earthquake. These events are often noticeable and can cause light damage to buildings near the epicenter, but rarely cause significant structural failure. Residents in the region should remain aware of the possibility of aftershocks, which are routine following a seismic event of this size.
