Magnitude 4.5 Earthquake Hits Sarangani Waters, Residents Alarmed Despite No Damage
Phivolcs says no damage or aftershocks expected, but nearby towns confirm the quake was felt indoors.
Notable Seismic Event
On Sunday night, a magnitude 4.5 earthquake off the coast of Maitum, Sarangani, gave residents of Southern Mindanao a momentary shock. When the earthquake was recorded at 7:54 p.m. by the Philippine Institute of Volcanology and Seismology (Phivolcs), the epicenter was located at a shallow depth of 10 kilometers, approximately 38 kilometers southwest of Maitum.
The start of the earthquake was tectonic. It was distinct, but not powerful enough to induce alarm. According to several residents, it sounded like a brief disturbance beneath the floor, long enough to cause you to look at the ceiling fan or watch a glass on the table tremble. Others acknowledged that they didn’t really notice it until their neighbors brought it up.
Instrumental Intensities Recorded
Phivolcs reported varying intensities across nearby areas:
- Intensity III – T’boli, South Cotabato
- Intensity II – Kiamba, Sarangani; Palimbang, Sultan Kudarat
- Intensity I – Maitum, Sarangani; Kalamansig, Sultan Kudarat
Intensity III generally means that the light inside is shaking. Things that are hanging may sway, and people who are sitting still will probably notice it. On the other hand, Intensity I is so weak that many people miss it completely. In the middle, the magnitude 4.5 earthquake was felt, but it didn’t cause any major problems.

No Threat of Aftershocks or Damage
According to Phivolcs, the magnitude 4.5 earthquake is not likely to cause aftershocks or damage to buildings. That might make people feel better, but some are still concerned. Even small tremors in Mindanao can bring back memories of major quakes that affect people for quite some time.
Mindanao’s Seismic Activity
Mindanao is on the Philippine Trench, which is one of the most active earthquake fault lines in the country. Even though the 4.5-magnitude earthquake in Sarangani may not seem like much, it is the latest in a long line of quakes in the area.
Preparedness and Public Awareness
Officials often stress that preparedness should not depend on the size of the last quake. The magnitude 4.5 earthquake may not have caused harm, but it serves as a quiet nudge to review safety habits. Simple steps—like knowing where to take cover at home or keeping a flashlight and first-aid kit handy—can make a difference when stronger quakes strike.
Local governments in Mindanao have been running earthquake drills in schools and offices. Participation varies. Some people take them seriously, while others admit they treat drills as routine interruptions. Still, experts argue that repetition builds instinct, and instinct is what saves lives when panic sets in.
Looking Ahead
The magnitude 4.5 earthquake in Sarangani occurred, but thankfully, there were no incidents, and daily life has swiftly returned to normal. The tremor highlights the Philippines’ situation as part of the Pacific “Ring of Fire.” Earthquakes are common in this area; they are an element of the landscape.
The response of communities is particularly noteworthy. Every event, regardless of its scale, challenges our preparedness and strength. Sunday’s magnitude 4.5 earthquake could act as a crucial practice run for what lies ahead—one that causes no damage but ideally helps people become a bit more ready.
