MANILA, Philippines: The Philippine Institute of Volcanology and Seismology (Phivolcs) has warned that more aftershocks can be expected following the magnitude 7.4 earthquake that struck Hinatuan town in Surigao del Sur on December 2, 2023. According to Phivolcs director Teresito Bacolcol, the strongest aftershock, measuring magnitude 6.6, occurred on December 3 at around 6:35 p.m.
Bacolcol stated that a total of 2,047 aftershocks have been recorded, with 25 of them being felt by residents in the province. However, he reassured the public that these aftershocks are gradually weakening and will continue to decrease in intensity in the coming days.
The use of state-of-the-art equipment by Phivolcs has greatly contributed to the increased detection of aftershocks compared to previous earthquakes. This advanced technology enables the agency to monitor seismic activity more accurately and provide timely information to the public.
In a separate event, a magnitude 5.7 aftershock was recorded on December 4 at 8:34 a.m. This aftershock was related to a magnitude 6.8 earthquake that occurred in Cagwait, Surigao del Sur town. Bacolcol emphasized that the Cagwait tremor was distinct and unrelated to the Hinatuan quake, as they were geographically far apart.
Phivolcs reported that residents in Bayabas experienced Intensity 4 shaking, while the City of Tandag recorded Instrumental Intensity 2. The City of Bislig, Cabadbaran City in Agusan del Norte, and Bislig City also experienced Intensity 1 shaking.
While no significant damage to property is expected, Bacolcol cautioned that aftershocks are still likely to occur. It is essential for residents in the affected areas to remain vigilant and follow safety protocols recommended by local authorities and Phivolcs.
Earthquakes are a common occurrence in the Philippines due to its location along the Pacific Ring of Fire, a region known for its seismic activity. The country experiences frequent tectonic movements, making it crucial for citizens to be prepared and educated about earthquake safety measures.
Local government units and disaster management agencies play a vital role in ensuring the safety and well-being of communities during and after an earthquake. They are responsible for conducting drills, disseminating information, and implementing measures to mitigate the impact of earthquakes.
In conclusion, the recent earthquakes in Surigao del Sur have resulted in numerous aftershocks, with Phivolcs expecting more to come. While the intensity of these aftershocks is gradually decreasing, it is important for residents to remain cautious and prepared. By staying informed and following the guidance of local authorities, individuals can minimize the risks associated with seismic activity and ensure their safety.
