Philippine seismologists say that a new offshore earthquake with a preliminary 6.8 magnitude hit the same southern region struck earlier by an earthquake with a magnitude of 7.4.
Two powerful offshore earthquakes struck the same region in the southern Philippines hours apart on Friday with the first 7.4 magnitude temblor killing at least seven people, setting off landslides and prompting evacuations of coastal areas nearby because of a brief tsunami scare.
The second one had a preliminary 6.8 magnitude and also sparked a local tsunami warning by authorities. It was caused by movement in the same fault line, the Philippine Trench, at a depth of 37 kilometers (23 miles) off Manay town in Davao Oriental province, Philippine Institute of Seismology and Volcanology chief Teresito Bacolcol said.
“The second one is a separate earthquake, which we call a doublet quake,” Bacolcol told The Associated Press. “Both happened in the same area but have different strengths and epicenters.”
Bacolcol and other authorities expressed fears that the second nighttime earthquake could further weaken or collapse structures already undermined by the first one.
President Ferdinand Marcos Jr., facing his latest natural disaster after a recent deadly quake and back-to-back storms, said the potential damage was being assessed and rescue teams and relief operations were being prepared and would be deployed when it was safe to do so.Quake toll
The first quake was centered at sea about 43 kilometers (27 miles) east of Manay town and was caused by movement in the Philippine Trench at a depth of 23 kilometers (14 miles), government seismologists said.
At least seven people were killed, including two patients who died of heart attacks at a hospital during the first earthquake and a resident who was hit by debris in Mati city in Davao Oriental, Ednar Dayanghirang, regional director of the government’s Office of Civil Defense, told The AP.
