EXPLAINER.WHAT IF TAAL VOLCANO FUTURE ERUPTIONS GENERATE DESTRUCTIVE TSUNAMIS?ANONG MANGYAYARI?


On Sunday, January 12, Taal Volcano started to spew ash, prompting massive evacuation in nearby areas.it was placed on Alert Level 4, which warns of a “hazardous” eruption that could happen “within hours to days.” The Philippine Institute of Volcanology and
Seismology raised Alert Level 4 on the Taal Volcano on Sunday night, hours after the phreatic eruption that occurred in the crater. According to Jenni Barclay, a volcanologist at the University of East Anglia, “the biggest bang is not always at the beginning of an eruption”. WHAT IF TAAL VOLCANO ERUPTION GENERATES DEVASTATING
TSUNAMIS? But before we delve further, let’s check
it out fast facts about taal volcano. Taal Volcano is one of the country’s 24 active
volcanoes and it is located within the Taal Lake which is a freshwater lake in the province
of Batangas, on the island of Luzon in the Philippines. The lake fills a large volcanic caldera formed by eruptions between 500,000 and 100,000 years ago. That crater lake is the world’s largest lake
on an island in a lake on an island, and it in turn contains its own small island, Vulcan Point. Taal Volcano has 47 craters and 4 maars, as a complex volcano system. It has an estimated 40-kilometer-wide zone of active volcanic activity in Luzon. A total of 34 eruptions had been recorded
within 448 years. The first recorded eruption was in 1572.
The biggest eruption was recorded in 1754 which lasted for 7 months between May and December. The latest eruptions before the 2020 explosion occurred in the 1970s. So, how do volcanic eruptions generate tsunamis? Let’s take a look on two diagrams of how
a volcanic eruption can generate a tsunami courtesy of Geoscience Australia. Although relatively infrequent, violent volcanic tsunamis, which used be known as seiche,(seysz) are displacements or disturbances of the water column. According to this mechanism, waves may be generated by the sudden displacement of water caused by a volcanic explosion, by a volcano’s slope failure, or more likely by a phreatomagmatic explosion and collapse/engulfment of the volcanic magmatic chambers. VOLCANIC ERUPTION TRIGGERS NUMBER 1 -LANDSLIDE. As you can see on the diagram presented, tsunami is caused by landslide, taking a deeper understanding on this as the waves approach shallow water, they definitely slow down, increase in height and get closer together. This is what we call shoaling. In the Inundation process, waves flooded or over run coastal areas.Then water draws back further than normal and is joined by the next inundating wave.That is generally how tsunami is being produced. Number two it triggers is earthquake. Let’s check it out the diagram again. If there is an earthquake on the ocean floor, this will result a sudden rise or fall of the earth’s crust.This movement can cause water above to rise or fall, creating of course tsunami waves in general. LET’S TAKE A LOOK ON ONE OF THE LARGEST TSUNAMI RECORDED IN HISTORY. One of the largest and most destructive tsunamis ever recorded was generated in August 26, 1883 after the explosion and collapse of the volcano of Krakatoa Krakatau), in Indonesia. This explosion generated waves that reached 135 feet, destroyed coastal towns and villages along the Sunda Strait in both the islands
of Java and Sumatra, killing 36,417 people. SO, CAN TAAL VOLCANO ERUPTIONS POSSIBLE OF
GENERATING BIG TSUNAMIS? The answer is yes!!! Taal current eruption also carries a tsunami risk because of the lake surrounding it. If part of the volcano’s flank collapses
into the lake, it could trigger such a wave which eventually causes tsunami. The triggered tsunami will affect not only
for those who live on the central volcanic isle, but also for the 25 million people living within 60 miles of the volcano, including a huge number on Lake Taal’s shorelines. SO, WHAT IF IF TAAL VOLCANO create a massive explosive eruption that triggers also a tremendous scale of earthquake that reaches to intensity 9 and eventually causes devastating tsunamis? The worst scenario? What if it will affect those areas more than
60 miles of the volcano. What will happen to nearby areas of Taal volcano like Laguna, Cavite and other coastal part of Metro Manila like Malabon, Valenzuela,
PARANAQUE CITY,LAS PINAS,Port areas & Manila Bay? If that happens?Let’s take a look on the massive impact and aftermath of devastating tsunamis First is Destruction and environmental impact. The amount of energy and water contained in a huge tsunami can cause extreme destruction when it strikes land. Tsunami waves destroy boats, buildings, bridges, cars, trees, telephone lines, power lines and just about anything else in their way. Once the tsunami waves have knocked down infrastructure on the shore they may continue to travel for several miles inland, sweeping away more trees,buildings, cars and other man made equipment. Small islands hit by a tsunami are left unrecognizable. The 2004 Indian Ocean tsunami was among the deadliest natural disasters in human history with at least 230,000 people killed or missing in 14 countries bordering the Indian Ocean. Tsunamis not only destroy human life. Tsunami changes the landscape. It uproots trees and plants and destroys animal habitats such as nesting sites for birds. Land animals are killed by drowning and sea animals are killed by pollution if dangerous chemicals are washed away into the sea, thus poisoning the marine life. Another environment impact is also to the
man-made aspects of the environment. Solid waste and disaster debris are the most critical environmental problem faced by a tsunami-hit country. Number 2 aftermath is Death & Disease
Even if you are inside a building, enjoying life like clubbing, if a destructive disaster
comes, you can not escape. One of the biggest and worst effects of a
tsunami is the cost to human life because unfortunately escaping a tsunami is nearly impossible. Hundreds and thousands of people are killed by tsunamis. Since 1850 alone, tsunamis have been responsible for the loss of more than 430,000 lives. There is very little warning before a tsunamis hits land. As the water rushes toward land, it leaves
very little time to map an escape plan. People living in coastal regions, towns and villages have no time to escape. The violent force of the tsunami results in
instant death, most commonly by drowning. Buildings collapsing, electrocution, and explosions from gas, damaged tanks and floating debris are another cause of death. The tsunami of December 2004 that struck South East Asia and East Africa killed over 31,000 people in Sri Lanka only, leaving 23,000 injured. Tsunami waves and the receding water are very destructive to structures in the run-up zone. The areas close to the coast are flooded with sea water, damaging the infrastructure such as sewage and fresh water supplies for drinking. Flooding and contamination of drinking water can cause disease to spread in the tsunami hit areas. Illnesses such as malaria arise when water is stagnant and contaminated. Under these conditions it is difficult for
people to stay healthy and for diseases to be treated, so infections and illnesses can
spread very quickly, causing more death. Third aftermath is Cost.
Massive costs hit communities and nations when a tsunami happens. Victims and survivors of the tsunami need immediate help from rescue teams. Reconstruction and clean up after a tsunami is a huge cost problem. The total financial cost of the tsunami could be millions or even billions of dollars of damage to coastal structures and habitats. The last aftermath is psychological effects Victims of tsunami events often suffer psychological problems which can last for days, years or an entire lifetime. Survivors of the Sri Lankan tsunami of December 2004 were found to have PTSD (post traumatic stress disorder) when examined by the World Health Organization (WHO): 14% to 39% of these were children, 40% of adolescents and 20% of mothers of these adolescents. These people were suffering from grief and depression as their homes, businesses and loved ones were taken from them.

  1. This is very informative, well researched and very well explained. You've done a great job with this but hopefully TAAL would stay quiet and no further catastrophe will happen.

  2. You finally made this public. Just pray for us bro. The Taal is currently calm right now and
    hopefully it will stay like this. We're praying it won't erupt again or even stronger cause
    once that happens and the alert level is raised to level 5, we will be in danger too. As of
    now, the alert level is still on level 4 but the Taal is very calm. We just feel minor
    earthquakes here and there in some parts of batangas. We are still busy helping other
    bantangeños and neighbours that are affected by this situation. And about the tsunamis, for
    sure it will occur because before Taal erupted, there was a visible island nearby which is now
    already underwater by the lake after the eruption.

  3. This is the best imformative about Taal issue happen this few days…Thank you

  4. This is really alarming considering that Taal is an active volcano. Had been visiting taal for years and loved its beauty but thinking the possible devastations it can create is another thing. Deep sigh!

  5. Nice intro, interesting volcano eruption video..enjoyed your video, thanks for sharing your video

  6. Hi po sna amaka punta naman po kayo s awaking mansion po party po Sana tayo po dali sa bahay ko po.
