1645 Luzon earthquake

The 1645 Luzon earthquake was one of the most destructive earthquakes to hit the Philippines. It occurred on November 30 at about 08:00 PM local time on Luzon Island in the northern part of the country. The island was struck by a 7.5 Ms tremor produced by the San Manuel and Gabaldon Faults (Nueva Ecija) in the central section of the island.[1]

Aftershocks continued a few days, then on December 4 at 11:00 pm, another event (allegedly equal or stronger than November 30) hit the area, causing further death and destruction.[2]

In Manila, damage was entirely severe: it almost "crumbled" ten newly constructed cathedrals in the capital, residential villas and other buildings. An estimated number of 600 Spanish people were killed, and about 3,000 Spanish were injured.[3][4]
