GEOLOGY

Detailed explanation-1: -Taal has 47 craters and four maars (a broad shallow crater). It is situated at the boundaries of two tectonic plates-the Philippines Sea Plate and the Eurasian plate-it is particularly susceptible to earthquakes and volcanism .

Detailed explanation-2: -While it is usually known to only have one crater, the volcano is actually a complex volcano system that consists of 47 volcanic craters. Its most popular crater is the Binintiang Malaki cone on the volcano’s northwestern tip. This now dormant crater is also what you can see from nearby Tagaytay City and nearby towns.

Detailed explanation-3: -In the caldera formed a lake and in a later stage a new volcanic island, today’s Taal volcano, was created in this lake. The new volcanic island is 23 square kilometers in size and eruptions produced 47 craters and smaller cones, including several maars.

Detailed explanation-4: -Volcanoes may have one summit crater, such as Mount Fuji in Japan. Or they may have several. Mount Etna, in Italy, has four. Some volcanoes are calm enough that scientists can get close to the lava in the summit crater.

Detailed explanation-5: -The volcano proper forms the Volcano Island, composed of seven volcanic cones and the caldera lake. Taal Lake is also a volcanic caldera, so the system is quite complex; some locals speak of underwater craters in the larger lake.
