The United States Geological Survey (USGC) recorded the depth of focus for the earthquake at 6.5 kilometers (4.0 mi),[5] deeper than what is recorded by PHIVOLCS.
The tremor was caused by the movement of the Leyte Segment of the Philippine Fault. A ground rupture was recorded in Barangay Tongonan in Ormoc which was described by the Department of Science and Technology as the epicenter area of the quake. As of July 9, PHIVOLCS was still assessing the extent of the rupture which could span 20 kilometers (12 mi) across the area.[6]
No tsunami warning was raised by the Pacific Tsunami Warning Center.[7]
Damage
The Department of Public Works and Highways Leyte Fourth Engineering District announced on July 10, 2017 that they estimate that at least ₱271 million of damage was caused by the earthquake. The local agency said that the city of Ormoc, and nearby town Kananga sustained the heaviest damage.[8]
The earthquake caused a building in Kananga to collapse, killing one person. Another person died in the town when a house collapsed in Ormoc.[4] Another person was killed in a landslide in Ormoc while another body was found in the same city.[2]
Authorities temporarily closed Ormoc Airport after its runway was damaged.[9]
Ten schools located in the towns of Kananga, Jaro, Barugo, and San Isidro were destroyed by the earthquake while ten more schools located in Inopacan, Albuera, Mérida, Barugo, and San Miguel were partially damaged.[10]
Leyte, Samar and Bohol experienced power blackouts while power supplies in Panay, Cebu, and Negros were also reportedly affected.[11]
Aftermath
PHIVOLCS recorded 796 aftershocks as of July 11, 2017.[12] Ormoc and Kananga declared a state of calamity.[13][14]
Residents in barangays Lake Danao and Tongonan in Ormoc were ordered to evacuate due to those localities being situated directly on the path of the Philippine Fault line.[10]
On August 23, 2017, an aftershock of magnitude 5.1 occurred.[15] This aftershock damaged 56 structures in Ormoc. Two people died, one after suffering a head injury after falling and another from a heart attack.[16]
