Link #86: World’s Largest Sub – Sub Island Is Only 40 Meters Wide!
If you read our last post, you will remember that Jamaica is an island country that boasts of 120 different rivers. Jamaica also happens to be one of the larger islands in the Caribbean. This is only one example of the diverse conditions and situations you can find in nature.
For example, you most probably know that there are two types of islands. The first type is like Jamaica, i.e., on an ocean, and the other type is on a lake. However, did you know that there could be islands within lakes that are themselves within islands on lakes or sub – sub islands?
If you think about it, you’ll realise that it is, indeed, very much possible. But how big can these sub – sub islands on a lake be? If you’re curious, read on.
How Large Is the Largest Sub – Sub Island?
The world’s largest sub – sub island on a lake, or island on a lake on a bigger island within another lake on another island is only 40 meters wide. This island’s name is Vulcan Island and it is located in the Philippines.
The Vulcan Island is located inside the Main Crater Lake, which is on the Volcano Island or the Taal Island. The Main Crater Lake spans about 2 km. The Taal Island is located inside Lake Taal which is, itself, on the Luzon Island.
In addition to being the world’s largest sub – sub island on a lake, Vulcan Point also happens to be the world’s largest volcano in a lake on a volcano. The bigger volcano in this case is the Taal Volcano.
These two titles aren’t the only ones within this complex of islands and lakes. The Main Crater Lake is the largest lake on an island (Taal Island), which is on a lake (Lake Taal) on another island (Luzon Island).
Is The Taal Volcano Active?
Taal Volcano is an active volcano which is a part of the Pacific Ring of Fire. The Pacific Ring of Fire is a region that sees the most earthquakes and volcanoes on Earth. Records suggest that the Taal Volcano has historically erupted 33 times.
The Taal Volcano is located on the Volcano Island which means that most of its eruptions were focused on this island. The last eruption of the Taal Volcano occurred in 1977.
Before 1977, there had been a number of different types of eruptions from this volcano spanning 12 years. Because of the activity of Taal Volcano, it was given the designation of a Decade Volcano.
What Is a Decade Volcano?
There are 17 Decade Volcanoes on Earth. Decade Volcanoes are chosen by the International Association of Volcanology and Chemistry of the Earth’s Interior for two reasons. The first is that they are active volcanoes and the other is that they are near population centres.
Decade Volcanoes are studied in detail to improve understanding of the phenomenon. Furthermore, people living around Decade Volcanoes are made aware of the risks pertaining to a volcanic eruption. The overall goal is to understand the process and keep the severity of volcanic eruptions to a minimum.
