ZAMBOANGA CITY – No casualties and damages were reported in this city from the magnitude-7.8 earthquake that struck off the coast of Sarangani on Monday morning.
But Mayor Khymer Olaso suspended classes on all levels and ordered half-day work at local government offices following the earthquake and tsunami alert.
Olaso said safety is non-negotiable in his decision to suspend classes on the first day of school. He advised residents to stay calm and vigilant, avoid panic and follow government advisories.
The City Disaster Risk Reduction Management Office was placed on full alert to respond to any emergencies.
The local government is assessing possible damages and casualties from the tremor.
Tsunami warning
The Philippine Institute of Volcanology and Seismology (Phivolcs) issued a tsunami warning for several coastal provinces in Mindanao.
The quake caused temporary alarm among residents but two tremors were experienced by this city, said Engr. Allan Labayog, chief of the Philippine Institute for Volcanology and Seismology Zamboanga City Station – Intensity 4 at 7:38 a.m. and Intensity 3 at 7:48 a.m.
Other areas in Zamboanga Peninsula experienced quakes with different magnitudes.
The Office of Civil Defense 9 has warned residents of coastal areas in Zamboanga Peninsula to evacuate to higher ground to protect themselves from a possible tidal wave or tsunami from the magnitude-seven earthquake.
Areas included in the advisory were Sarangani, Davao Occidental, Tawi-Tawi, Sulu, Basilan, Zamboanga del Sur, Zamboanga Sibugay, Sultan Kudarat, and South Cotabato.
The first tsunami waves, assessed to exceed one meter above normal tide levels, were forecast to arrive between 7:37 a.m. and 9:37 a.m. and may continue for several hours.
People in coastal areas were advised to immediately evacuate to higher grounds or move farther inland.
Owners of boats in harbors, estuaries, or shallow coastal water were also advised to secure their boats and move away from the waterfront.
Evacuation ordered
The Pagadian City government issued a pre-emptive evacuation order for all residents in coastal barangays following the tsunami warning.
Residents were strongly advised to proceed immediately to higher ground or elevated land areas as a precautionary measure.
Disaster personnel were ordered on ground to monitor the areas, coordinate with barangay officials, and assist in the evacuation.
Residents were advised to stay in safe areas until an official “all clear” order is issued.
Classes suspended
ILIGAN CITY – Classes here were suspended on Monday and Tuesday due to the earthquake.
Mayor Frederick Siao issued Executive Order No. 61, Series of 2026, as a precautionary measure to ensure the safety and well-being of students, teachers, and school personnel.
This will also allow concerned agencies to assess the condition of school facilities and monitor possible impacts of the earthquake before classes resume.
