Volcanoes
How do volcanoes form?
Volcanoes can be formed when magma pushes up through the earth's surface between cracks in tectonic boundaries. Another way could be when magma chambers begin opening up beneath the earth's surface, pushing magma through forming volcanoes.
Where are volcanoes most likely to form?
Volcanoes are only able to form where one tectonic plate sinks into the earth's mantle underneath another tectonic plate.
What volcano am I focussing on?
The volcano I am researching is Mauna Loa.
The latest eruption from this volcano was the 15th of April 1984.
The amount of damage that was caused, wasn't that bad, there was no one injured due to the eruption, but it did cover 16 miles worth of land owned by the state.
Facts.
It has been 30 years since the last eruption from Mauna Loa recking 4.5 miles of Hilo, and the eruption lasted from March the 25th to April the 15th.
Mauna Loa has caused around 77 deaths in an eruption during 1846, 46 died due to a volcanic tsunami, and 31 from volcanic mudflows.
The area of the volcano is 5,271km².
This volcano is located in Hawaii in the Pacific Ocean.
It is known for being the worlds largest volcano in both volume and mass, dwarfed only by the Tamu Massif which is located East of Japan.
Here are some photos of The Mauna Loa:
