Ring of Fire

The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 kilometers (25,000 miles) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arc, and volcanic belts and/or plate movements.

The Ring of Fire has 452 volcanoes and is home to over 75% of the world's active volcanoes. It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt. From as many as 129 volcanoes in Indonesia or 13 percent of all volcanoes in the world, encircled stretches all of Indonesia island.

The volcanoes in Indonesia are among the most active of the Pacific Ring of Fire. They are formed due to subduction zones of three main active tectonic plates namely the Eurasian Plate, Pacific Palte, and Indo-Australian Plate.  

Some of the volcanoes are notable for their eruptions, for instance, Karakatau, for its global effects in 1883, Lake Toba for its super volcanic eruption estimated to have occurred 74,000 years ago which was responsible for six years of winter, and  Mount Tambora for the most violent eruption in recorded history in 1815. The eruption of Mount Tambora in 1815 caused wide spread harvest failures in Northern Europe, the Northeastern United States, and eastern Canada in 1816, which was known as “The Year Without Summer".

The most active volcano is Mount Merapi on Java Island which has been responsible for thousands of deaths in the region. Merapi has erupted more than 80 times. The International Association of Volcanology and Chemistry of The Earth's Interior has named Merapi as a "Decade Volcano"  since 1995 because of its high volcanic activity.

However, some volcanoes in Indonesia, Many stores a number or more, the beauty of the scenery is stunning. There are several mountains in Indonesia which has a lake in the vicinity and even in its crater.
