Question

Taal volcano eroption case study

Answer 1

Answer:

Normally, the view from the webcam sitting inside Lake Taal in the Philippines shows clouds drifting over the lake’s placid waters, as verdant slopes rise in the distance. But on the afternoon of January 12, this peaceful scene was suddenly interrupted by a torrent of hot ash and gas, before the camera was smothered by darkness.

Explanation:

The outpouring marked the beginning of an unnerving eruption sequence at 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.

So far, no casualties have been reported, and there is a chance this eruption could fizzle out. Still, many people likely remain in high-risk zones, and “the biggest bang is not always at the beginning of an eruption,” says Jenni Barclay, a volcanologist at the University of East Anglia. “On a timescale much longer than the threat of a hurricane, something else could happen that’s even bigger.”

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.

Answer 2

Volcano erupts in the taal lake. An ash cloud rises over the lake at the time of volcano eruption . In Philippines on january 12 the taal volcano eruption was occur.

Explanation:

• Researchers in the Philippines are monitoring the Taal volcano closely for signs of a major eruption.
• The volcano’s activity has eased since it began spewing steam and ash more than a week ago, but the threat of a large-scale eruption remains, say scientists.
• The eruption will occur it create immediate risk to life , such as contaminate water supply and break power generation and stop land and air travel.
• From sixteenth century, Taal has erupted about 30 times, including four major events.
• In january 12, high level of seismic activity is the reason for the taal volcano eruption.
