A series of earthquakes is currently being monitored offshore Surigao del Norte, Philippines. This earthquake swarm started with a magnitude 5.5 earthquake on 26 April 2019. As of 5:00 AM (PST) on 30 April, the Philippine Seismic Network had already recorded 728 events with magnitudes ranging between 1.5-5.5, and clustering in the same area/vicinity.
These events are associated with the ongoing subduction of the Philippine Sea Plate along the Philippine Trench.
At this early stage, the current earthquake activity may indicate two scenarios:
- it may continue with its present activity and eventually wane in the next few days,
- the swarm may culminate into a larger and destructive earthquake.
The swarm is still ongoing today.
The Philippine Institute of Volcanology and Seismology DOST-PHIVOLCS is continuously monitoring.
People in the area should prepare for the worst and stay informed. Regular updates will be posted on their website and official social media accounts. Always be ready!
