DAVAO DEL SUR — The Philippine Institute of Volcanology and Seismology (PHIVOLCS) plans to install 300 additional seismic stations nationwide over five years, starting in 2027, under an announced agency modernization effort. Officials reported that the country’s existing seismic-monitoring network currently includes 130 stations.
The expansion target was disclosed by PHIVOLCS Director Teresito Bacolcol during a DOST project visit ahead of the Regional Science, Technology, and Innovation Week and Handa Pilipinas Mindanao activities in Davao Region, according to a Department of Science and Technology release published October 20, 2026.
Expansion target would add stations to existing network
Bacolcol described a plan to install 300 more stations over the next five years, beginning the following year with PHIVOLCS modernization. The existing 130-station figure and the additional 300-station target are figures reported in the release; they should not be read as 430 stations already in service.
The DOST report does not specify which provinces or sites would receive the new stations, how many would be installed in each year, the modernization program’s total approved budget, contract awards or the milestones required to bring individual installations into operation.
Davao del Sur visit highlights strong-motion measurements
The announcement appeared in DOST’s report on a visit to a strong-motion monitoring station at Davao del Sur State College in Digos City. DOST Secretary Renato Solidum Jr. explained that strong-motion instruments record earthquake waveform data that engineers can use when designing buildings and other structures.
Strong-motion measurements are important for understanding the shaking experienced at a location. That engineering application is distinct from a promise that an expanded station network will predict the occurrence of earthquakes.
Davao del Sur State College officials said the local installation also supports earthquake monitoring, research, education and disaster risk reduction. DOST described it as an existing project supported through collaboration with the college.
What has been announced—and what remains pending
The new nationwide deployment figure is a five-year plan, not an announcement that 300 stations have been procured, delivered, installed or commissioned. Nor does the release establish the equipment mix or prove that earlier PHIVOLCS procurement invitations are components of this specific modernization rollout.
WVF has separately covered GNSS, LiDAR and seismic-reflection equipment bidding and SeisComP earthquake-processing software licensing. Those procurement-stage developments should not be added to the new 300-station plan as confirmed deployments.
Why it matters for earthquake resilience
A wider and properly maintained seismic-monitoring network could strengthen the geographic reach and quality of earthquake observations. Strong-motion records can also inform engineering assessments and the design of safer structures. Those potential benefits will depend on where stations are sited, how they are equipped and how reliably their data are processed and maintained.
