According to data previously released by the Philippine Volcanoes and Seismological Institute, at 8:43 a.m. on July 27, a 7.3-magnitude earthquake occurred in the northern part of The Philippine Island, with a depth of 25 kilometers, and the capital Metro Manila area was felt. The earthquake is expected to have aftershocks.
According to the Ministry of Natural Resources, the Tsunami Warning Center judged based on preliminary seismic parameters that the earthquake may cause a local tsunami around the source, but will not cause a catastrophic impact on the continental coast.
