were likewise converted into | | |ruins. No better fared the palace of the |
| |Governor-General, the Real Audiencia and | | |up to 150 of the finest
residences which, | | |as one author puts it, "in other cities | | |would
have been considerable palaces." The | | |rest of the private houses were
damaged | | |to so great an extent that the majority | | |had to be
demolished. The number of | | |persons killed exceeded 600 and the
total | | |of killed and injured is stated to have | | |been 3,000. | | | | |
|Outside of Manila there was a general | | |destruction of villas and other
buildings | | |which had been erected on both banks of | | |the Pasig
River. Throughout the | | |neighboring provinces the masonry | |
|structures built by the missionaries | | |suffered the same fate as those in
Manila. | | |From the farthest provinces in the north | | |were reported
great alterations of the | | |surface with almost complete disappearance |
| |of some native villages, changes in the | | |courses of rivers,
subsidences of plains, | | |eruptions of sand, etc. All the writers of | | |the
time qualify this disturbance as the | | |most disastrous earthquake not
only in | | |Luzon, but likewise in Mindoro, | | |Marinduque, and the
other islands south of | | |Luzon. On the other hand, the provinces of | |
|Camarines and Albay appear to have | | |suffered little or nothing. | | |
13 |1645 XII 5 23 -- |VIII |The earthquake of November 30 was
followed | | |by almost daily repetitions and countless | | |aftershocks,
one of which, on December 5, | | |was of such intensity as to finish the |
| |wrecking of many buildings, "leaving [as a | | |chronicler writes] the
city in such | | |condition that it was impossible to walk | | |through it."
Aftershocks of variable force | | |continued to be very frequent
throughout | | |an entire year; that is, until the end of | | |1646. | | |

| | |provinces. | | | 17 |1658 VIII 20 17 -- | IX |Destructive earthquake.
Some historians | | |maintain that it was as severe as that of | | |1645; but
it caused fewer ruins, partly on | | |account of its short duration, partly | |
|because it found buildings of less height | | |and greater power or
resistance than those | | |erected before 1645. Nevertheless it | |
|destroyed the monastery of Santa Clara and | | |did great damage to the
churches and | | |monasteries of the Dominicans and | | |Recollects,
likewise to the archiepiscopal | | |palace, the Jesuit College, and a | |
|considerable number of private buildings. | | |The epicentral region
appears to have | | |included only the southern part of Luzon. | | | 18
|1665 VI 19 -- -- |VIII |Destructive in Manila and adjacent | | |provinces.
In the ruins of numerous houses | | |19 persons perished and many more
were | | |injured. Of public buildings only the | | |Jesuit Church is
mentioned as having | | |suffered to some extent. | | | 19 |1675 II -- -- --
|VIII |Destructive in northern Mindoro and | | |Batangas Province.
Mention is made of | | |extensive landslides, the opening of many | |
|fissures and the subsidence of large | | |tracts on the beach of the
northeast | | |coast of Mindoro. The repetitions were many | | |and severe.
