A magnitude 4.8 earthquake near Tahuna, Kabupaten Kepulauan Sangihe, Sulawesi Utara, Indonesia, was reported only 24 minutes ago by the United States Geological Survey, considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a moderately shallow depth of 35. km beneath the epicenter early morning on Monday, April 20th, 2026, at 2:35 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 4.8 as well. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.8, Indonesia's Meteorology, Climatology, and Geophysical Agency at magnitude 4.5, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) at magnitude 4.5, and the citizen-seismograph network of RaspberryShake at magnitude 4.5.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tahuna (pop. 35,300) located 119 km from the epicenter.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
