The 1628 Camarines earthquake struck Camarines, in the Philippines in 1628. [2] Fourteen different shocks were recorded. [3] The date is unknown. [4] The United States' National Geophysical Data Center describes the damage as "severe" and the total number of homes damaged as "many". [1]

The Philippine Atmospheric, Geophysical and Astronomical Services Administration is the National Meteorological and Hydrological Services (NMHS) agency of the Philippines mandated to provide protection against natural calamities and to ensure the safety, well-being and economic security of all the people, and for the promotion of national progress by undertaking scientific and technological services in meteorology, hydrology, climatology, astronomy and other geophysical sciences. Created on December 8, 1972, by reorganizing the Weather Bureau, PAGASA now serves as one of the Scientific and Technological Services Institutes of the Department of Science and Technology.
The 1990 Luzon earthquake struck the island of Luzon in the Philippines at 4:26 p.m. on July 16 (PDT) or 3:26 p.m. (PST) with an estimated moment magnitude of 7.7 and a maximum Mercalli intensity of IX (Violent) 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. An estimated 1,621 people were killed, most of the fatalities located in Central Luzon and the Cordillera region.
On August 17, 1983, at 20:17 PST (UTC+08:00), an earthquake struck the island of Luzon in the Philippines. The shock had a surface wave magnitude of 6.5 and a maximum Mercalli intensity of VIII (Severe), killing 16 people and injuring 47. Seven towns were damaged, several buildings collapsed, and electricity was cut off in Laoag. Features like sand volcanoes and cracks formed during the quake.
The 1897 Mindanao earthquakes occurred on September 20, 1897, at 19:06 UTC and September 21, 1897, at 05:12 UTC. The estimated epicentres of the two earthquakes are identical, lying just off the southwestern coast of Mindanao in the Philippines, south of Basilan island. The earthquakes were originally given estimated magnitudes of 8.6 and 8.7 on the surface wave magnitude scale by Charles Richter, but these were revised downwards by Katsuyuki Abe to 7.4 and 7.5 Ms, respectively. Contemporary reports noted that with few exceptions, all the masonry buildings in Zamboanga and Basilan were left in ruins.
The 1918 Celebes Sea earthquake occurred on August 15 at 12:18 UTC near the Moro Gulf coast of Mindanao. It had a magnitude of 8.3 on the moment magnitude scale and a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale.
