“The second one is a separate earthquake, which we call a doublet quake,” Bacolcol told The Associated Press.
Another resident died because of the first quake in the port city of Davao, disaster mitigation officials said without providing other details.
People darted out of houses and buildings as the ground shook and electricity came off,” Jun Saavedra, a disaster-mitigation officer of Governor Generoso town in Davao Oriental, told The AP.
Children evacuated schools in Davao city, which has about 5.4 million people and is the biggest city near the epicenter, about 250 kilometers (155 miles) west of Davao Oriental province.
A tsunami warning that set off evacuations in six coastal provinces near Davao Oriental was later lifted without any major waves being detected, Bacolcol said.
MANILA, Philippines (AP) — On Friday, four hours apart, two strong offshore earthquakes struck the same area in the southern Philippines. The first, a 7.4 magnitude quake, killed at least seven people, caused landslides, and forced the evacuation of nearby coastal areas due to a brief tsunami warning.
A local tsunami warning was issued by authorities in response to the second one, which had a preliminary magnitude of 6point 8. Teresito Bacolcol, the head of the Philippine Institute of Seismology and Volcanology, stated that it was brought on 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.
“The second one is a doublet quake, which is a separate earthquake,” Bacolcol told The Associated Press. Although they both took place in the same location, their epicenters and strengths differed. “.”.
Authorities, including Bacolcol, were concerned that the second nighttime earthquake might further erode or destroy buildings that had already been damaged by the first.
President Ferdinand Marcos Jr. said that rescue teams and relief operations were being prepared and would be deployed when it was safe to do so. He was dealing with his latest natural disaster following a recent deadly earthquake and back-to-back storms.
Quake toll.
According to government seismologists, movement in the Philippine Trench at a depth of 23 kilometers (14 miles) was the cause of the first earthquake, which was centered at sea roughly 43 kilometers (27 miles) east of Manay town.
Ednar Dayanghirang, regional director of the government’s Office of Civil Defense, told The AP that at least seven people were killed, including a resident struck by debris in Mati city, Davao Oriental, and two patients who passed away from heart attacks at a hospital during the first earthquake.
Dayanghirang said that the first earthquake caused a landslide in a remote gold-mining village in Pantukan town in Davao de Oro province near Davao Oriental, killing three villagers and injuring several others who were rescued by army troops and civilian volunteers.
Disaster mitigation officials said that another resident died as a result of the first earthquake in the port city of Davao, but they did not elaborate. They also mentioned that several hundred city dwellers had been hurt.
appraisal of damage.
Several buildings, including an international airport in Davao City, had wall cracks, according to Office of Civil Defense deputy administrator Bernardo Rafaelito Alejandro IV. However, the airport continued to function normally, with no flights being canceled.
“My car started to sway while I was driving, and I noticed power lines swaying erratically.”. As the earth trembled and the electricity went out, people hurried from homes and structures, Jun Saavedra, a disaster-mitigation officer in the Davao Oriental town of Governor Generoso, told The AP.
Schools were closed.
“This was the strongest earthquake we’ve had,” Saavedra said, adding that the strong ground swaying caused cracks in a number of buildings, including a high school where roughly fifty students were taken to a hospital by ambulance after suffering bruises, fainting, or feeling lightheaded due to the initial quake.
Classes at all levels were also suspended in Governor Generoso, a town located roughly 60 miles (100 kilometers) south of Manay.
Schools in Davao City, the largest city close to the epicenter and home to roughly 5.4 million people, which is located roughly 250 kilometers (155 miles) west of Davao Oriental province, had to evacuate their students.
fear of tsunamis.
Before the threat subsided, roughly two hours after the initial earthquake, small waves were seen on the Indonesian and Philippine coasts, according to the Pacific Tsunami Warning Center in Honolulu. It stated that slight sea variations might persist.
Six coastal provinces close to Davao Oriental were evacuated after a tsunami warning was canceled, according to Bacolcol, without any significant waves being spotted.
According to the Indonesian Meteorology, Climatology and Geophysics Agency, Melonguane, Beo, Essang, and Ganalo districts in the Talaud Islands province experienced minor tsunami waves that ranged in height from 3 to 5 centimeters (1 to 6 to 7 inches) in North Sulawesi province.
Earthquake and storm history.
The Philippines has yet to recover from a September attack. A magnitude 6point 9 earthquake that struck the central province of Cebu, specifically in Bogo city and surrounding towns, caused thousands of people to be displaced and at least 74 fatalities.
About 20 typhoons and storms hit the archipelago annually, so government and volunteer organizations have a big job responding to disasters.
Additionally, Friday saw an earthquake off the coast of Papua New Guinea with a preliminary magnitude of 6point 0. The U. A. According to the Geological Survey, its center is in the Bismarck Sea, 414 kilometers (257 miles) northeast of Lae, the second-most populated city in the South Pacific island nation.
According to Lae police official Mary Jane Huafilong, there were no reports of damage.
