A powerful 6.4 magnitude earthquake struck in the Philippine Sea on Wednesday, according to the United States Geological Survey.
The earthquake struck at 11:02 a.m. Philippine time, about 17 miles (27 kilometers) east of Santiago, Philippines, agency data showed.
USGS data previously reported the magnitude was 6.7.
As seismologists review the available data, they may revise the reported magnitude of the earthquake. Additional information gathered about the earthquake may also lead USGS scientists to update the earthquake severity map.
