A 7.4-magnitude earthquake was reported in the Philippines on Friday (October 10), according to the United States Geological Survey.
The earthquake was centered about 20 east of Santiago, at a depth of 58.1 kilometers (about 36 miles). The USGS said it received 11 reports of people having felt the earthquake as part of its preliminary report.
A tsunami warning was issued by the Philippine Institute of Volcanology and Seismology for Mindanao, Philippines, "with life threatening wave heights" expected.
"It is expected to experience wave heights of more than one meter above the normal tides and may be higher on enclosed bays and straits," the alert stated via the Guardian.
The U.S. Tsunami Warning System, however, confirmed that there was "no tsunami danger for the U.S. West Coast, British Columbia or Alaska."
"Based on earthquake information and historic tsunami records, the earthquake is not expected to generate a tsunami," the alert added.
Two aftershocks, a 5.9-magnitude in the Philippines, and a 6.0-magnitude in Papua New Guinea, were reported in the Pacific after the initial 7.4-magnitude earthquake.
The Philippines are among the countries most prone to earthquakes as it's located on the 'Ring of Fire' region where earthquakes commonly occur in the Pacific. The Santiago earthquake was reported hours after 5.5-magnitude earthquake was reported in China on Thursday (October 9), according to the United States Geological Survey. The earthquake was centered in Xinlong, about 130 miles north of Daocheng, at a depth of 10 kilometers (about 6.2 miles)
