Magnitude 4.2 Earthquake Strikes Tahuna, Indonesia at Depth of 476 km

A magnitude 4.2 earthquake struck the Tahuna area in the Sangihe Islands Regency of North Sulawesi, Indonesia on April 23, 2024. The quake occurred at a depth of 476 km, according to seismic data.

No further details were immediately available about the impacts of the earthquake in the region. Tahuna is located in a seismically active area of Indonesia.

North Sulawesi experiences an average of 717 earthquakes per year, with 4 quakes above magnitude 8 recorded since 1900. In the past 30 days alone, the region has seen 21 quakes between 4.0 and 5.0 magnitude.

The strongest recent earthquake in the area was a magnitude 6.5 event that occurred 2 weeks ago in the Northern Molucca Sea. Just 3 hours before the Tahuna quake, a magnitude 2.9 tremor was detected in the Philippine Sea near the coast of North Sulawesi.

Why this matters: Indonesia is located in the seismically active "Ring of Fire" region, where the Indo-Australian Plate is subducting beneath the Eurasian Plate. This tectonic setting makes Indonesia prone to frequent earthquakes, volcanic eruptions, and occasional tsunamis, emphasizing the importance of monitoring seismic activity and having robust emergency preparedness measures in place.

While the depth of 476 km would typically lessen the potential for major damage from a magnitude 4.2 quake, authorities continue to assess the situation in the Tahuna area. "We are collecting damage reports and other information from the field to get a full picture of the earthquake's effects," said a spokesperson for Indonesia's disaster management agency. Residents are advised to stay alert for potential aftershocks in the coming days.
