An earthquake of magnitude 4.5 occurred only 22 minutes ago 95 km southwest of Iloilo City, Philippines, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported.
The quake hit at a moderately shallow depth of 36 km beneath the epicenter near Iloilo City, Iloilo, Western Visayas, Philippines, in the evening on Tuesday, August 29th, 2023, at 9:17 pm 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.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
