Near the long-run baseline โ only background factors are mildly elevated.
Activity level 2/3
A vigorous open hydrothermal system raises the chance of steam-driven (phreatic) activity.
Basis: PHIVOLCS hydrothermal monitoring

Low b-value (0.68) suggests high stress accumulation and potential for larger events

No eruptions in the last 10 years.
Volcanic activity clusters in episodes โ recent eruptions raise near-term probability.
Basis: GVP eruption history
No qualifying large earthquakes in range/time window
Large nearby earthquakes can perturb the magma/hydrothermal system (static + dynamic stress).

Elevated shallow, near-field seismicity can indicate magma or fluid movement.
Basis: Volcano-seismic monitoring (PHIVOLCS / USGS)
No coherent migration detected
Insufficient data for depth migration analysis
Basis: Hypocenter migration (Roman & Cashman 2006)
No acceleration detected
Accelerating seismicity can precede failure of the edifice/conduit.

Most eruptions ~VEI 2; capable of large (VEI โฅ 4) events โ largest recorded VEI ~6.
Sparse / largely unknown history โ the rate is dominated by a volcano-type prior, with wide uncertainty.

How this is calculated โFAQ
Mount Talomo has a very low modeled chance of erupting in any given year. Based on Mount Talomo's eruption history, our model estimates roughly a 0.5% chance of an eruption within the next 12 months (about one eruption every 400 years on average). This is a statistical estimate, not a definite prediction โ always follow official PHIVOLCS advisories.
Mount Talomo has no confirmed eruption on record in the Smithsonian Global Volcanism Program database.
Mount Talomo is classified as potentially active. It is a stratovolcano in Davao Region, Philippines, rising to 2,674 m.
About 950,000 people live within 30 km of Mount Talomo. The current modeled hazard level is background. Local hazard zones and typical eruption size are detailed on this page.
Mount Talomo is located in Davao Region, Philippines, at 7.095ยฐ, 125.455ยฐ, with a summit elevation of 2,674 m.
