Taal Volcano Earthcache
To reach the volcano, you need to travel by boat, then either hike, or use a horse to reach the summit of the crater.
From there you will be able to see the smaller island inside volcano.
Taal Volcano is part of a chain of volcanoes along the western side of the island of Luzon, which were formed by the subduction of the Eurasian Plate underneath the Philippine Mobile Belt.
Taal Lake lies within a 25–30 km caldera formed by four explosive eruptions between 500,000 and 100,000 years ago. Each of these eruptions created extensive ignimbrite deposits, reaching as far away as where Manila stands today.
Since the formation of the caldera, subsequent eruptions have created another volcanic island, within the caldera, known as Volcano Island. This island covers an area of about 23 km², and consists of overlapping cones and craters. 47 different cones and craters have been identified on the island.
To log this find,
- What is the PH of the water inside the volcano, and in the lake surrounding it.
- What is the elevation difference between the outer lake, and the inner lake.
- Post a photo of the inner island.
