This earthquake is one of the most damaging in terms of structural damages due to earthquake in the 20th century in the Philippines. All kinds of seismic hazards such as intense ground shaking, liquefaction, ground rupture, landslide and tsunami and even secondary hazard such as fire were experienced. This earthquake occurred at 4:26 PM (DST). Epicenter was on land in the province of Nueva Ecija, where ground rupture of as much as 125 km was observed. Liquefaction caused tracts of land to settle by as much as 1-2 meters, most notably in the city of Dagupan, some parts of the shoretowns of La Union such as Agoo and Aringay, including some towns of Tarlac province such as Gerona and Pura. Landslides were observed in the Cordillera Mountains hampering access to towns in these mountainous areas. Despite the fact that the epicenter was on land, two-meter high waves were reported by local residents of Brgy. (reference #10958)
