Real-time coverage of earthquake event — 67 km ESE of Pondaguitan, Philippines — Pandita Data.
🌍 OPEN LIVE 3D EARTHQUAKE MAPA magnitude 6.2 earthquake struck 67 km east-southeast of Pondaguitan in Davao Oriental province, Philippines, on June 15, 2026 at 09:18 UTC. The rupture occurred at 111.9 km depth—deep enough to limit severe ground shaking in nearby communities but energetic enough to be felt across the region. The USGS issued a GREEN PAGER alert, indicating low casualties and minimal structural damage expected. No tsunami warning was issued due to the depth and offshore location of the rupture.
The Philippines sits at the convergent boundary where the Philippine Sea Plate subducts beneath the Eurasian Plate at rates of 7–10 cm per year. This region hosts the Philippine Trench—one of the deepest oceanic trenches on Earth—and generates frequent seismic activity along multiple fault systems. Pondaguitan lies in eastern Mindanao, a zone dominated by the Philippine Fault System and subduction-related ruptures. The depth of 111.9 km places this event within the Wadati-Benioff zone, the inclined plane of descending oceanic lithosphere where intermediate-depth earthquakes occur. These deep events release energy through phase transitions in cooling, pressurized rock rather than brittle fracture, making them thermodynamically distinct from shallow crustal earthquakes.
This magnitude 6.2 event released approximately 7.9 × 1016 joules of energy—equivalent to 19 kilotons TNT. At 111.9 km depth, the rupture occurred within the subducting oceanic slab where pressure and temperature are high enough to dehydrate minerals and trigger sudden stress release. Deep-focus earthquakes produce longer-duration seismic waves that attenuate less rapidly through the mantle, allowing them to be felt over larger areas than shallow earthquakes of the same magnitude. However, peak ground acceleration—the most damaging frequency content—decays significantly by the time waves reach the surface, explaining the low PAGER rating despite the substantial energy release.
At 111.9 km, this rupture sits well below the crustal–mantle boundary (~35 km). The attenuating effect of deep focus reduces intensity at the surface by roughly 1–2 magnitude units compared to a shallow rupture of the same seismic moment. Ground shaking intensity in Pondaguitan (67 km away) was likely II–III on the Modified Mercalli scale—felt by alert people indoors, minor rattling of objects. Tsunami generation requires vertical seafloor displacement; deep subduction-zone ruptures displace less water column than shallow events, explaining the absence of a tsunami warning.
Davao Oriental province, home to approximately 1.5 million people, experienced weak to light shaking. Pondaguitan, a coastal municipality with limited high-rise infrastructure, faced minimal immediate risk. The broader region—including Davao City (1.6 million) and surrounding agricultural and mining zones—is accustomed to regular seismic activity and has building codes designed to withstand such events. Historically, the Philippines experiences one magnitude 6+ earthquake every 1–2 years along its subduction zones. This event underscores the continuous geodynamic activity that shapes the archipelago's topography and volcanic landscape.
