PHIVOLCS has Recorded Approximately 2,400 Aftershocks since the Abra Earthquake

According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), approximately 2,400 aftershocks have been recorded since the magnitude 7 quake that occurred in Abra on July 27.

“Marami na pong nangyaring aftershocks sa Abra at saka paligid na mga probinsya. Mga 2,400 na aftershocks na ang naitala since July 27,” PHIVOLCS chief Renato Solidum Jr. said at a public briefing.

(There have been approximately 2,400 aftershocks recorded in Abra and surrounding provinces since July 27.)

He also stated that the number of daily aftershocks has been decreasing.

The strongest aftershock detected thus far was magnitude 5.1 with an intensity of V, or strong shaking, according to Solidum.

He stated that such aftershocks really wouldn’t cause further damage to infrastructure, but they could cause landslides.

According to Solidum, Intensity VI is hazardous to damaged buildings. He advised impacted residents not to return to their homes or businesses until an investigation and repair were completed.

However, the PHIVOLCS chief clarified that the cracks discovered in the affected areas are not “new fault lines,” but rather the result of landslides, liquefaction, and sand boils.
