Moderate 4.7 quake hits near Santa Cruz, Zambales, Central Luzon, Philippines
4.7 quake 25 Feb 10:55 am (GMT +8)
According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the quake hit on Thursday 25 February 2021 at 10:55 am local time at a very shallow depth of 4 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 4.7 as well.
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.
Weak shaking might have been felt in Ilioilio (pop. 2,100) located 72 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Santa Cruz (pop. 26,400) located 93 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.
