Magnitude 5.3 earthquake from Sunda Strait felt early morning, BMKG data shows

An earthquake with a magnitude of 5.3 struck the Sunda Strait early Wednesday, shaking parts of Banten, Indonesia. The Indonesian Meteorology, Climatology, and Geophysics Agency (BMKG) reported the epicenter was located in the sea, approximately 62 kilometers southwest of Sumur in Pandeglang, Banten, at a depth of 43 kilometers.

BMKG's modeling indicated that the earthquake does not pose a tsunami risk. The agency classified the event as a shallow earthquake resulting from subduction activity. This type of seismic activity occurs in subduction zones, where tectonic plates collide, and is known for its potential to generate powerful earthquakes.

The strongest tremors were felt in Sumur, registering at IV on the Modified Mercalli Intensity (MMI) scale. At this intensity, the earthquake was noticeable by many indoors, causing rattling of dishes, windows, and doors, and audible sounds from walls. BMKG advised residents to remain calm and to avoid damaged buildings. As of early Wednesday morning, no aftershocks had been detected.
