ABSTRACT: At 08:28 PM Philippine Standard Time (PST), 15 January 2023, a shallow moderate earthquake with magnitude (Mw) 4.7 shook the northern part of Leyte Province and its neighboring islands. The hypocenter was located at 11.33°N, 124.54°E – 7 km S 55° E of Leyte, Leyte with a depth of one (1) kilometer. The ground shaking was felt at PHIVOLCS Earthquake Intensity Scale (PEIS) VI (very strong) in areas along the strike of the Philippine Fault – Leyte segment in the municipality of Leyte and the easternmost part of Tabango, Leyte Province and as far as Bogo City, Cebu at PEIS I (scarcely perceptible). Based on the epicentral location, focal mechanism, and actual field observations, the earthquake was generated by the Leyte Segment of the Philippine Fault. The National Disaster Risk Reduction and Management Council (NDRRMC) reported that the earthquake caused 18 injured persons and damaged 434 residential houses and 26 public infrastructures (NDRRMC Progress Report No. 3, 26 January 2023), and the estimated cost of damage to structures is about 27.6 million Philippine pesos or 502 thousand US dollars.
