菲律宾被认为是东南亚地震活动性最高的地区之一。这是由于其复杂的地质构造，也归因于它位于地震活动性集中的环太平洋火山带。菲律宾的地震活动性主要与板块消减有关菲律宾平均每天发生５次有感和无感地震，棉兰老东部、莱特和萨马却年平均有感地震１６次。因而这些地区被认为比其他地区更易发生地震。１６世纪以来，菲律宾发生了许多次有文字记载的破坏性地震。近年来发生的最强烈的破坏性地震是１９７６年８月１６日的莫罗湾地震（ＭＳ＝７．９），这次地震引起了海啸，造成了许多人死亡和财产损失；１９９０年７月１６日吕宋地震（ＭＳ＝７．８）引起了沿菲律宾断裂带北部地段的运动；１９９４年１１月１４日民都洛岛地震（ＭＳ＝７．１）则引起了Ａｇｌｕｂａｎｇ河断层的运动，并引发了小海啸。菲律宾地震记录早在殖民地时期就已开始。但是，直至１９４８年菲律宾大气地球物理气象服务管理局（ＰＡＧ－ＡＳＡ）安装了它自己的地震仪器后，才开始采用仪器观测。１９８６年，上述机构的地震学任务移交给菲律宾火山与地震研究所（ＰＨＩＶＯＬＣＳ）承担。目前，该研究所有２９个人工管理的地震观测台和３个遥测地震台网。每个人工管理的台站都配备有短周期地震仪，且每天２４小时运转。地震数据通?
The Philippines is considered as one of the most seismically active areas in Southeast Asia. This is due to its complex geological structure, also due to its location in the Pacific Rim volcano with concentrated seismicity. Earthquakes in the Philippines are mainly related to the subsidence of the plateau. On average, the Philippines have felt and felt no earthquakes five times a day. However, the eastern Mindanao, Wright and Samar averaged 16 earthquakes a year on average. These areas are therefore considered more prone to earthquakes than other areas. Since the 16th century, there have been many devastating earthquakes recorded in the Philippines. The most devastating earthquake that struck in recent years was the Morro Bay earthquake (MS = 7.9) on August 16, 1976, which caused a tsunami that caused many deaths and property damage; July 1990 On the 16th, the Luzon earthquake (MS = 7.8) caused a movement along the northern segment of the Philippine fault zone. On November 14, 1994, the Mindoro Island earthquake (MS = 7.1) caused the movement of the fault of the Aglubang River, And triggered a small tsunami. Seismological records in the Philippines began as early as the colonial era. However, instrument observation was not started until the PGA-ASA installed its own seismometer in 1948. In 1986, the agency’s seismological mission was handed over to the Philippine Institute of Volcanoes and Earthquakes (PHIVOLCS). Currently, there are 29 artificially managed seismic stations and three telemetered seismic stations in this research institute. Each manually managed station is equipped with a short-period seismograph and operates 24 hours a day. Earthquake data pass?
