A very shallow 4.7 magnitude earthquake was reported early in the morning near the town of Iloilo, Iloilo, in the western Visayas, Philippines.
According to the Euro-Mediterranean Seismological Center (EMSC), the earthquake struck on Monday, September 20, 2021 at 4:49 am local time at a very shallow depth of 1 km. Shallow earthquakes are felt more strongly than deep ones because they are closer to the surface. The exact magnitude, epicenter and depth of the quake could be revised in the coming hours or minutes, as seismologists review the data and refine their calculations, or when other agencies release their report.
Our monitoring service identified a second report from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) which also listed the earthquake at a magnitude of 4.7.
Based on preliminary seismic data, the quake was likely felt by many people in the epicenter area. It should not have caused any significant damage, other than objects falling from shelves, broken glass, etc.
In Bugasong (2,800 inhabitants) located 9 km from the epicenter, the earthquake should have been felt as slight tremors.
Weak tremors could be felt in Iloilo City (pop. 387,700) located 60 km from the epicenter, and Passi (pop. 42,800) at 62 km.
Other towns close to the epicenter where the earthquake could have been felt as very weak tremors include Kalibo town (56,800 residents) 87 km from the epicenter, Bago City (150,300 residents) 95 km , Talisay (65,300 inhabitants) 99 km, Roxas City (102,700 inhabitants) 99 km, Bacolod City (454,900 inhabitants) 100 km and Binonga (84,000 inhabitants) 100 km.
VolcanoDiscovery will automatically update the magnitude and depth if these change and follow up if other significant earthquake news becomes available.
