via PHIVOLCS Tsunami Information:

A major earthquake occurred in offshore Sarangani on 08 June 2026 at 07:37 AM Philippine Standard Time (PST), located at 05.57°N, 124.98°E with depth of 33 km and a magnitude of 7.8. DOST-PHIVOLCS issued a TSUNAMI WARNING for all coastal communities in the provinces of Sarangani, Basilan, Davao Occidental, South Cotabato Sultan Kudarat, Sulu, Tawi-Tawi, Zamboanga Del Sur, and Zamboanga Sibugay. Immediate evacuation in these areas was recommended. Between 07:45 A.M to 9:30 A.M., the following PHIVOLCS Sea Level Monitoring Stations for tsunami confirmed the occurrence of tsunami with preliminary wave heights:

Location	Tsunami Height (meters)
Kiamba, Sarangani	1.48
Kalamansig, Sultan Kudarat	0.84
Maasim, Sarangani	0.48
City of Zamboanga	0.25
City of Mati, Davao Oriental	0.21
City of Tandag, Surigao del Sur	0.09

After the extended two-hour observation period, minor sea level disturbances continued to be recorded; however, these observed wave heights are too small to cause damage. In view of these observations, DOST-PHIVOLCS has now cancelled the Tsunami Warning issued for this earthquake event. In the event of strongly felt aftershocks, coastal communities should recognize the natural signs of an impending local tsunami. These include “shake,” a strong earthquake, “drop”, the sudden rise or fall of seawater, and “roar,” the sound of incoming waves. If ANY of these signs are observed, immediately evacuate to higher ground for safety. This will be the final tsunami information issued for this event.

The cancellation of the tsunami warning was issued two hours after the Province of Sarangani was hit by a 7.8-magnitude earthquake that damaged a lot of property and left 19 dead with 12 people still missing.
