The Philippine Institute of Volcanology and Seismology (PHIVOLCS) is a service institute of the Department of Science and Technology (DOST) that is principally mandated to mitigate disasters that may arise from volcanic eruptions, earthquakes, tsunami and other related geotectonic phenomena.
The violent eruption and resulting casualties and damages from Hibok-hibok Volcano in 1951 made the nation realize the necessity to seriously monitor and conduct studies on active volcanoes in the country. As there was no government agency at that time that is in-charge of this task, the Commission on Volcanology (COMVOL) was created in June 20,1952 through Republic Act No. 766, primarily to "safeguard life and property against volcanic eruptions and its dangers." COMVOL was initially placed under the Executive Board of the National Research Council and later under the National Science Development Board (NSDB).
On 17 March, 1982, Executive Order 784 reorganized the NSDB and its agencies into the National Science and Technology Authority (NSTA). COMVOL was restructured and renamed Philippine Institute of Volcanology (PHIVOLC).
On September 17, 1984, seismology or the science that deals with earthquakes, was transferred to the Institute from Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). PHIVOLC was renamed Philippine Institute of Volcanology and Seismology (PHIVOLCS).
On January 30, 1987, by virtue of Executive Order No. 128, the NSTA was structurally and functionally transformed into the Department of Science and Technology was granted its present mandates.
As specified in Executive Order No. 128, PHIVOLCS has been mandated to perform the following functions:
- Predict the occurrence of volcanic eruptions and earthquakes and their geotectonic phenomena;
- Determine how eruptions and earthquakes shall occur and also areas likely to be affected;
- Exploit the positive aspects of volcanoes and volcanic terrain in furtherance of the socio-economic development efforts of the government;
- Generate sufficient data for forecasting volcanic eruptions and earthquakes; and
- Formulate appropriate disaster-preparedness and mitigation plans.
A leading global science and technology institution in helping develop communities safe from and resilient to volcanic eruptions, earthquakes, tsunamis and other related hazards.
We provide timely and quality information and services for warning, disaster preparedness and mitigation. This we do through the development and application of technologies for the monitoring and accurate prediction of and determination of areas prone to volcanic eruptions, earthquakes, tsunamis and other related hazards, and capacity enhancement for comprehensive disaster risk reduction.
The objectives of the institute are:
1. To develop and maintain effective networks of volcanological, seismological and geophysical stations and facilities for monitoring, R&D purposes and disaster mitigation.
2. To develop the capability to repair, upgrade and fabricate instruments used in volcano and seismic monitoring and R&D activities.
3. To conduct research to increase the level of understanding/knowledge about volcanoes, volcanic eruptions and terranes, earthquake zones and mechanism, faulting, along with other related geotectonic phenomena.
4. To adapt and develop technologies for volcanic eruption and earthquake prediction, volcano and seismic monitoring and disaster mitigation.
5. To conduct R&D on the impact of volcanic eruption, earthquake and other related geotectonic phenomena on the physical and socio-economic environment and recommend appropriate measures for the mitigation of impacts and rehabilitation of affected areas.
6. To implement an aggressive S&T information processing and dissemination program to promote public awareness on the significance of volcanic activity, earthquakes and related geotectonic processes and their threats and possible benefits to man.
7. To identify, evaluate and characterize volcanic materials and energy products and generate/adapt technologies for their utilization.
The Institute is composed of four technical divisions: (1) Volcano Monitoring and Eruption Prediction Division (VMEPD), (2) Seismological Observation and Earthquake Prediction Division (SOEPD), (3) Geology and Geophysics Research and Development Division (GGRDD) and (4) Geologic Disaster Awareness and Preparedness Division (GDAPD), and a Finance and Administrative Division (FAD).
