No, the Apolaki Caldera Is Not Active and Poses No Threat
I saw this image circulating online showing a massive glowing ring east of the Philippines, the Apolaki Caldera.
For those who arenāt familiar, the Apolaki Caldera is a real geological structure located deep beneath the sea in the area known as the Philippine Rise (formerly Benham Rise). This underwater formation is so huge that it holds the title of the largest known caldera in the world, with an estimated diameter of around 150 kilometers, even larger than Yellowstone or Toba.
It was formed millions of years ago, likely after a series of enormous volcanic eruptions that reshaped the ocean floor and left behind this vast circular depression. The name Apolaki was inspired by the ancient Filipino god of the sun and war, a fitting name for something so grand and mysterious beneath our seas.
Recently, some posts online have linked Apolaki to the earthquakes on September 30 and October 10, claiming that it might be āawakening.ā
However, thereās no scientific evidence to support this claim.
Those earthquakes were tectonic, caused by natural movements along the Earthās fault lines, not by volcanic activity.
The Philippines lies within the Pacific Ring of Fire, so earthquakes are normal and expected here. These quakes, while strong, are not signs that the Apolaki Caldera is becoming active.
The truth is, the Apolaki Caldera remains dormant, meaning it has been inactive for millions of years.
So while the idea of a giant underwater volcano may sound terrifying, thereās no need to panic.
Letās stay informed, not alarmed.
The Philippines is home to some of the worldās most fascinating geological wonders, and Apolaki is one of them, a silent reminder of our planetās powerful past, not a present threat. šµšš
And please, stop spreading fake news that only causes fear and confusion.
If something serious ever happens, letās wait for official updates from PHIVOLCS, DOST, or other trusted authorities before believing or sharing anything online. š
Letās use social media to educate, not terrify, and keep calm, kababayan.
