1880 Luzon earthquakes
The earthquakes of July 1880 in Luzon, the largest island of the Philippines, was one of the most destructive tremors on record in the history of the country. The shocks continued, with greater or less interruption, from the 14th to the 25th of the month, highlighted by three violent shaking events, which destroyed churches and other buildings, producing loss of life. Coinciding with the tectonic activity was an increased in volcanic activity in Taal Volcano in southwestern Luzon.The Luzon provinces of Manila, Cavite, Bulacan, Laguna, Pampanga, and Nueva Ecija, were the chief victims from the terrible convulsions with Manila and Laguna receiving the most damages. In many places, buildings were converted into shapeless heaps of ruins, and the materials of their prosperity buried beneath the rubbish.
