The Philippine Institute of Volcanology and Seismology (Phivolcs) has issued a strong call to the public to take tsunami advisories seriously, as recent earthquakes in the country have shown that some warnings were not heeded. The director of Phivolcs, Teresito Bacolcol, specifically referred to the magnitude 6.8 earthquake in Davao Occidental on November 17 and the magnitude 7.4 earthquake in Surigao del Sur on December 2.
Following the November 17 quake, Phivolcs released a tsunami warning, cautioning coastal communities about potential sea-level rise. Although no destructive tsunami was expected, it was crucial for people to remain cautious. Similarly, after the December 2 tremor, Phivolcs advised coastal communities in Surigao del Sur and Davao Oriental to evacuate to higher ground or move farther inland due to possible tsunamis.
The magnitude 7.4 earthquake, with its epicenter in the waters off the town of Hinatuan, Surigao del Sur, not only affected Mindanao island but also reached the Visayas region. Bacolcol emphasized the severity of the event, stating, “This event triggered tsunami alerts in the Philippines and southern Japan, while the two earthquakes reached a maximum intensity of 7, which means destructive.”
Despite the warnings, some individuals did not take the tsunami advisory seriously. Bacolcol highlighted that social media posts and media reports provided a comprehensive overview of what happened during and after the earthquake, including people taking ill-advised risks to photograph the tsunamis. Although the tsunamis that occurred were not destructive, social media posts showed individuals defying the advisory by approaching the shoreline and filming as the sea water receded and then returned.
In response to these incidents, Bacolcol urged the public to refrain from documenting such phenomena if they find themselves at the coastline or on the beach during a strong earthquake. He emphasized, “You never know if a tsunami might follow.” Phivolcs stressed the importance of familiarizing oneself with the natural signs of an impending tsunami: Shake, Drop, and Roar.
Bacolcol explained the significance of these signs, stating, “Shake: If you’re near the coast and experience a powerful earthquake that makes it difficult to stand. Drop: If you notice the sea level dropping. Roar: If you hear a roaring sound from the sea.” He further advised, “Even if you observe just one of these signs, move to higher ground as there might be an incoming tsunami.”
It is crucial for individuals living in coastal areas to understand the potential dangers associated with earthquakes and tsunamis. By heeding the warnings and being aware of the natural signs, lives can be saved. Phivolcs continues to emphasize the importance of taking tsunami advisories seriously, as even a seemingly harmless situation can quickly turn into a life-threatening one.
As an international audience, it is essential to understand the context of these events within the Philippines. The local laws and customs play a significant role in how people respond to natural disasters. The Phivolcs’ warnings and advisories are based on extensive research and analysis of seismic activities in the region. Therefore, it is crucial for individuals to trust and follow the guidance provided by the authorities to ensure their safety and well-being.
By raising awareness about the importance of taking tsunami advisories seriously, we can contribute to a safer and more prepared society. Let us all remember that in the face of natural disasters, it is better to be cautious and proactive rather than regretful and reactive.
