PHIVOLCS Observatory at Mount Hibok-Hibok.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS, Tagalog: [ˈfivolks]; Tagalog: Surian ng Pilipinas sa Bulkanolohiya at Sismolohiya[2]) 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.

PHIVOLCS monitors volcano, earthquake, and tsunami activity, and issues warnings as necessary. It is mandated to mitigate disasters that may arise from such volcanic eruptions, earthquakes, tsunamis, and other related geotectonic phenomena.[3]

History

This government organization was formed after a historical merging of official functions of government institutions.

One of its first predecessors is the Philippine Weather Bureau created in 1901[4] when meteorological, seismological and terrestrial magnetic services of the Manila Observatory were transferred from the Roman Catholic Church to the American Colonial Government. It performed earthquake monitoring in the country and has inherited and maintained the early earthquake catalogue at that time. By 1972, the Philippine Weather Bureau was reorganized under Presidential Decree No. 78[5] into the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA). A United Nations Development Programme-funded project for PAGASA established a twelve-station earthquake monitoring network in the country.

In February 1951, Dr. Jose M. Feliciano, Chair of the Division of Physical and Mathematical Sciences of the National Research Council of the Philippines (NRCP) presented a proposal for the creation of a Commission on Volcanology. The eruption of Mount Hibok-Hibok in December 1951 and the consequent destruction and loss of lives led to the closer cooperation by the Geology, Seismology, and Volcanology Section, committee on Volcanology of the Department of Agriculture and Natural Resources, to study volcanoes in the Philippines.[6] This collaboration let to the enactment of Republic Act No. 766[7] on June 20, 1952 that created the Commission of Volcanology (COMVOL). This Commission was placed under NRCP and its office was initially set up in the College of Liberal Arts in UP Diliman.[6] Under Executive Order No. 784 of March 17, 1982, the umbrella department of COMVOL, the National Science Development Board (NSDB) was reorganized into the National Science and Technology Authority (NSTA), and COMVOL was restructured to become the Philippine Institute of Volcanology or PHIVOLC.[8]

The seismological arm of PAGASA was officially transferred to PHIVOLC[9] on September 17, 1984 through Executive Order No. 984, renaming the institute as the Philippines Institute of Volcanology and Seismology or PHIVOLCS.[10] The NSTA, the umbrella department for PHIVOLCS and PAGASA, became the Department of Science and Technology (DOST) in 1987. The technical staff and the 12-station earthquake monitoring network was fully integrated to PHIVOLCS in 1988.

PHILVOCS and the United States Geological Survey collaborated during the 1991 eruption of Mount Pinatubo. Their forecast provided the timely evacuation of military personnel and residents that were affected by the eruption.[11]

PHIVOLCS was headed by Raymundo Punongbayan from 1982 to 2002,[12] and it is currently headed by Renato U. Solidum Jr. from 2003 to the 2023.

Dr. Teresito C. Bacolcol was appointed as the new Director and took his oath on January 23, 2023, with Science and Technology Secretary Dr. Renato U. Solidum, Jr. in Quezon City.[13]

Classification of volcanoes in the Philippines

In 1984, pyroclastic flows descend the south-eastern flank of Mayon Volcano, the most active volcano in the Philippines

PHIVOLCS classifies volcanoes as active, potentially active, or inactive:[14]
