Taal Volcano could erupt again

Tectonic volcanic explosion do is cause of tsunamis and other devastating natural occurrences:

Taal Volcano, which sits on the island of Luzon. On the first day, steam-driven blasts flung ash nine miles into the sky. Startling displays of volcanic lightning ricocheted around this dark maelstrom, and a myriad of intense volcanic earthquakes rocked the region. On January 13, the eruption became somewhat more magmatic, as lava fountains started shooting up from the main crater.

Ash continues to blanket the Philippines as of press time, including in the capital city of Manila, about 62 miles north of the volcano. Flights have been cancelled, schools and other public institutions have closed, and tens of thousands of people have been evacuated from both the volcanic isle within Lake Taal and from the vast shorelines around it.

Philippines, officials have warned that a Taal volcano near Manila could erupt again in the coming days and the impact could be prolonged. The Taal volcano, located about 60 kilometres from the capital, erupted on Sunday, sending smoke to a height of 15,000 metres and spewing volcanic ash. The eruption is believed to have been a steam blast is source of endangering millions of lives.With its could continue boiling liquid ash for months endangering millions of lives in the vicinity.

Past eruptions at Taal demonstrate that this volcano has a profoundly lethal capability, claiming thousands of lives throughout recorded history. If the latest event does become more explosive—a possibility that has scientists deeply concerned—it could yield a surfeit of volcanic hazards, from rocky debris bouncing across the lake to overwhelming tsunamis.

“This is definitely a volcano to be taken seriously,” says Beth Bartel, an outreach specialist at UNAVCO, a geoscientific consortium of universities and scientific institutions.


The Philippine Institute of Volcanology and Seismology has said that smoke is still rising to a height of about 2,000 meters and more than 280 volcanic earthquakes have been observed. The institute has raised the level to the second highest level of 4.

Authorities told that more than 30,000 people have been evacuated and about 200 shelters have been set up. Officials in Batangas province, where the volcano is located and nearby Cavite province have decided to keep schools closed today.

Ash can pollute water supplies, damage electronic infrastructure, smother agriculture, and kill off farm animals and pets. It can also kill people if they inhale enough of it; breathing in glassy ash is always bad, but people with pre-existing respiratory ailments are most at risk, as are the very young and the elderly.

Either through explosive mixing of magma and water, or through magmatic activity alone, Taal has also previously produced thundering, high-velocity clouds of hot ash, debris, and gas named pyroclastic flows that have killed thousands of people in mere moments. Boris Behncke, a volcanologist at Italy’s National Institute of Geophysics and Volcanology, shared some examples on Twitter, including flows from a 1911 eruption that killed 1,335 people on the central island.

A reasonable worst-case scenario would not just feature pyroclastic flows, but also low-altitude surges of ash and scorching gas that, due to their low density, can literally bounce over the water, says Donovan. These base surges—a term borrowed from nuclear explosion science—“can sandblast everything in their path, including the lake shore on the other side,” Bartel says.
