Taal Volcano

 



Taal Volcano is located about 60 km SSE of Metro Manila, the capital of the Philippines. It is a complex volcanic system composed of a small volcanic island (Volcano Island), which has been the site of almost all historic activity, located within a 20x30 km lake-filled complex caldera(?) (Taal Lake, in older texts was also called Lake Bonbon), one of the great volcano-tectonic depressions of the world.


Taal as the Decade Volcano for the Philippines Thirty three eruptions have been recorded since 1572 at Taal, mostly on Volcano Island. The impacts of these eruptions were largely confined to the intracaldera area. Occasional violent activity, however, such as the 1754 plinian eruption, affected the entire region, including what is now the Metro Manila area with fallout. Some activity, such as the 1749 eruption, were accompanied by crustal disturbance and strong earthquakes, which generated ground fissures and pronounced subsidence that extended across Taal Lake. 

Taal Volcano, in the Philippines, was originally a huge volcano, that towered 18,000 feet up into the sky. It has been called the smallest active volcano, because it seems small now, but many people don't realize that it is one of the largest volcanoes in the world. It is located about 60-km south of Manila on "volcano island" inside a lake called Taal Lake, or Lake Taal. The picture of Taal volcano above, was taken from Tagaytay ridge. Actually, Tagaytay Ridge is the rim of the volcano! When the volcano was 18,000 feet high, Tagaytay ridge would have been only about a sixth of the way to the top of the volcano!! In the distance, across the lake, is Mt. Makulot.
