Taal Volcano. Violent in | | |Manila and the Provinces of Rizal, Laguna, | | |Cavite, and Batangas. Connected with an | | |eruption of the volcano. At each spasm of | | |the latter the earth shook so violently | | |that many buildings in Manila and the | | |provinces mentioned suffered much harm, | | |especially those in the vicinity of Lake | | |Bombon, within which is situated the said | | |volcano. | | | 24 |1728 XI 28 -- -- | IX |Remarkable on account of its having been | | |very perceptible throughout the entire | | |Archipelago. Caused considerable damage in | | |Manila and towns in southern Luzon. | | | 25 |1730 -- -- -- -- | IX |Destructive in the Provinces of Tayabas | | |and Laguna; ruined the church and the | | |church and convento at Mauban and other | | |buildings in this and other towns of the | | |two provinces. | | | 26 |1743 -- -- -- -- | IX |Destructive in Tayabas Province, wrecking | | |masonry structures in the town of Tayabas | | |and others. | | | ----+--------------------+-----+------------------------------------------ No. | Date. |Intensity. | | | Epicenter and effects. ----+--------------------+-----+------------------------------------------ | Y. M. d. h. m. | | 27 |1749 VIII 12 9 -- | IX |A violent eruption of Taal Volcano, which | | |caused great havoc in all the towns on the | | |shores of Lake Bombon. The shocks which | | |accompanied each of the intermittent | | |outbursts of the volcano were so severe | | |that they left hardly any building | | |undamaged throughout the provinces in the | | |neighborhood of Manila--Rizal, Laguna, | | |Cavite, Batangas, Tayabas, and in northern | | |Mindoro. The convulsions of the ground | | |were very remarkable; displacement | | |occurred and fissures, both wide and deep, | | |opened in the entire Province of Batangas | | |and likewise in Cavite Province, up to | | |Lake Bay. As the shocks occurred during | | |many days, the majority of Manila's | | |inhabitants abandoned the Walled City and | | |lived under tents or in structures of | | |bamboo and nipa. The greatest force of | | |the earthquakes and, consequently, the | | |greatest upheavals seem to have occurred | | |in the region stretching from Taal Volcano | | |toward Talim Island (Lake Bay) and the | | |Antipolo Mountain Range. | | | | | |Repetitions and aftershocks were frequent | | |during nearly a year. | | | 28 |1754 V 15 21 -- | X |Another eruption of Taal Volcano, the most | | |terrible in the history of the Islands. | | |All the towns which surrounded Lake Bombon | | |were destroyed completely. When rebuilt, | | |they were placed at a distance from the | | |lake. There occurred most violent | | |earthquakes which produced disasters in | | |the neighboring provinces equal too, if | | |not exceeding those of 1749. The spasms, | | |separated by intervals of greater or less | | |duration, lasted 7 months, the principal | | |outbursts being always accompanied by very | | |intense earthquakes which made themselves | | |felt throughout a large part of Luzon, on | | |Mindoro Island, and northern Panay. | | | 29 |1766 XII 7 10 45 | VII |A violent earthquake, but did very slight | | |damage in Manila. During the month many | | |more earthquakes of less intensity were | | |felt; in fact they had been frequent ever | | |since the preceding August. There exist no | | |data concerning the provinces around | | |Manila. | | | 30 |1767 II 8 1 5 | VII |Manila and neighboring provinces. Violent | | |earthquake, preceded and followed by | | |numerous shocks of smaller intensity. | | | 31 |1767 XI 13 15 25 | VII |Very violent. In Manila a few walls fell | | |and tile roofs sagged. Slight repetitions | | |marked the succeeding days. Nothing is | | |known of the happenings in the near-by | | |provinces. | | | 32 |1770 XII -- 23 -- |VIII |Destructive earthquake. Mr. Sonnerat | | |states that it wrecked many houses in | | |Manila. This traveler was at the time on | | |board a ship in the very Bay of Manila; | | |hence it is very strange that he does not | | |give the day of the month on which the | | |disaster took place. | | | 33 |1771 II 1 -- -- |VIII |Very severe earthquake which laid in ruins |
