Where is the most volcano activity?
Indonesia has more volcanoes than any other country in the world. The 1815 eruption of its Mount Tambora still holds the record for the largest in recent history. Indonesia is one of many places located within the world’s most volcanically, and seismically, active zone, known as the Pacific Ring of Fire.
How do volcanic activities occur?
When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions. In the ocean, volcanoes erupt along cracks that are opened in the ocean floor by the spreading of two plates called a mid-ocean ridge .
What are the volcanic activities?
Volcanic activity ranges from emission of gases, non-explosive lava emissions to extremely violent explosive bursts that may last many hours. A volcanic event occurs when there is a sudden or continuing release of energy caused by near-surface or surface magma movement. …
Where are the active volcanoes most likely to form?
Active volcanoes are most likely to form at convergent oceanic-continental boundaries
Where most actively do volcanoes occur?
The US has the largest number of volcanoes totaling 173, and most of them are found in Alaska , where eruptions take place almost every year. Other volcanoes are found in Hawaii and Kilauea is the most active volcano in the world that has erupted continuously since 1983.
Where do volcanos and earthquake most often occur?
Earthquakes and volcanoes occur most frequently along the Pacific Rim of Fire. This area is a textonic plate subduction zone. Subduction zones are associated with volcanic activity and their associated eartquakes.
Where do earthquakes and volcanoes usually occur and why?
Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. At diverging plate boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates.
