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 to Kayapa. 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. An estimated 1,621 people were killed, most of the fatalities located in Central Luzon and the Cordillera region.
