The 1990 Luzon earthquake occurred on July 16 at 4:26 p.m. (PDT) or 3:26 p.m. (PST) on the densely populated island of Luzon in the Philippines. The shock had a surface-wave magnitude of 7.8 and produced a 125 km-long ground rupture that stretched from Dingalan, Aurora to Kayapa, Nueva Vizcaya. The event was a result of strike-slip movements along the Philippine Fault and the Digdig Fault within the Philippine fault system. The earthquake's epicenter was near the town of Rizal, Nueva Ecija, northeast of Cabanatuan.[6] An estimated 1,621 people were killed,[7][8] most of the fatalities located in Central Luzon and the Cordillera region.
