Taal Volcano is a large caldera filled by Taal Lake in the Philippines. Located in the province of Batangas about 50 kilometers (31 mi) south of Manila, the volcano is the second most active volcano in the country with 38 recorded historical eruptions, all of which were concentrated on Volcano Island, near the middle of Taal Lake. The caldera was formed by prehistoric eruptions between 140,000 and 5,380 BP.
Dr. Raymundo Santiago Punongbayan was the former director of the Philippine Institute of Volcanology and Seismology (PHIVOLCS) from 1983 to 2002. Punongbayan became popular after handling two well-known calamities, the 1990 Luzon earthquake and the 1991 Pinatubo eruption. PHIVOLCS is the government agency in charge of conducting volcanic and earthquake monitoring in order to generate data that could be used to predict volcanic eruptions and earthquake occurrences.
The Department of Science and Technology, is the executive department of the Philippine government responsible for the coordination of science and technology-related projects in the Philippines and to formulate policies and projects in the fields of science and technology in support of national development.
Kanlaon, also known as Mount Kanlaon and Kanlaon Volcano, is an active stratovolcano and the highest mountain on the island of Negros in the Philippines, as well as the highest point in the Visayas, with an elevation of 2,465 m (8,087 ft) above sea level. Mount Kanlaon ranks as the 42nd-highest peak of an island in the world.
Mount Leonard Kniaseff, or simply Leonard Kniaseff, is a stratovolcano between the municipalities of Mabini and Maco in the province of Davao de Oro, island of Mindanao, Philippines.
The Philippine Institute of Volcanology and Seismology is a Philippine national institution dedicated to provide information on the activities of volcanoes, earthquakes, and tsunamis, as well as other specialized information and services primarily for the protection of life and property and in support of economic, productivity, and sustainable development. It is one of the service agencies of the Department of Science and Technology.
The 1976 Moro Gulf earthquake and tsunami occurred on near the islands of Mindanao and Sulu, in the Philippines. It measured 8.0 on the moment magnitude scale occurring at a depth of 20 km (12 mi). The earthquake was accompanied by a destructive tsunami that resulted in a majority of the estimated 5,000 to 8,000 fatalities. It was the deadliest and strongest earthquake in the Philippines in 58 years since the 1918 Celebes Sea earthquake.
The Marikina Valley Fault System, also known as the Valley Fault System (VFS), is a dominantly right-lateral strike-slip fault system in Luzon, Philippines. It extends from Doña Remedios Trinidad, Bulacan in the north and runs through the provinces of Rizal, and the Metro Manila cities of Quezon, Marikina, Pasig, Taguig and Muntinlupa, and the provinces of Cavite and Laguna that ends in Canlubang.
The 2012 Negros earthquake occurred on February 6 at , with a body wave magnitude of 6.7 and a maximum intensity of VII (Destructive) off the coast of Negros Oriental, Philippines. The epicenter of the thrust fault earthquake was approximately 72 kilometres (45 mi) north of Negros Oriental's provincial capital, Dumaguete.
The order of precedence in the Philippines is the protocol used in ranking government officials and other personages in the Philippines. Purely ceremonial in nature, it has no legal standing, and does not reflect the presidential line of succession nor the equal status of the three branches of government established in the 1987 Constitution.
The secretary of science and technology is the head of the Department of Science and Technology and is a member of the president's Cabinet.
The 2017 Surigao earthquake occurred on February 10, 2017, at 10:03 PM (PST), with a surface wave magnitude of 6.7 off the coast of Surigao del Norte in the Philippines. According to the PHIVOLCS Earthquake Intensity Scale the earthquake was an Intensity VII (Destructive) earthquake at maximum. In the past Surigao province has been hit by a magnitude 7.2 tremor in both 1879 and 1893.
The PHIVOLCS Earthquake Intensity Scale is a seismic scale used and developed by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) to measure the intensity of earthquakes.
On July 6, 2017, a 6.5 magnitude earthquake hit Leyte, causing at least 4 deaths and 100 injuries. The quake also caused power interruptions in the whole of Eastern Visayas and nearby Bohol.
On December 12, 1999, a 7.3 earthquake struck the northern coast of Zambales in the Philippines. It was felt in various provinces on the island of Luzon including as far north as Ilocos Norte and as far south as Quezon. This is the second earthquake with a magnitude of 7 to hit the area in 10 years with a 7.7 earthquake having occurred in 1990 which killed more than 2,000 people.
The 2019 Cotabato earthquakes were an earthquake swarm which struck the province of Cotabato on the island of Mindanao in the Philippines in October 2019. Three of these earthquakes were above 6.0 on the moment magnitude scale with a Mercalli intensity of VIII. More than 40 people have been reported dead or missing and nearly 800 were injured as a result of these events.
Taal Volcano in Batangas, Philippines began to erupt on January 12, 2020, when a phreatomagmatic eruption from its main crater spewed ashes over Calabarzon, Metro Manila, and some parts of Central Luzon and Ilocos Region, resulting in the suspension of school classes, work schedules, and flights in the area. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) subsequently issued an Alert Level 4, indicating "that a hazardous explosive eruption is possible within hours to days." Volcanic activity continued into 2021, when smaller eruptions occurred in July 2021. On 26 March 2022, a short-lived phreatomagmatic eruption was recorded by PHIVOLCS raising the status from Alert level 2 to Alert level 3 as well as surrounding towns.
On July 27, 2022, at 8:43:24 a.m. (PHT), an earthquake struck the island of Luzon in the Philippines. The earthquake had a magnitude of 7.0 Mw , with an epicenter in Abra province. Eleven people were reported dead and 615 were injured. At least 35,798 homes, schools and other buildings were damaged or destroyed, resulting in ₱1.88 billion (US$34 million) worth of damage.
