DUE Volcanic Eruptions


DUE volcanic eruptions
Volcanic eruptions can be very powerful to be able to destroy the surrounding environment. When the volcano erupted published various materials which include:
1. Dense material (eflata), which consists of eflata autogen and eflata alogen.
Eflata can be shaped as follows:
a. bomb
Namely eflata large.
b. lapilli
Namely eflata small.
c. volcanic sand
Eflata ie sand-sized.
d. ash
That is fine as dust eflata.
e. pumice
Namely eflata shaped frozen foam.
2. Liquid material (effusive) occurs when there is no stopper so it will come out lava liquid magma in the form:
a. Lava (magma that reaches out into the earth's surface) with a temperature between 900̊ C - 1200̊ C.
b. hot lava
c. cold lava
3. Material gas (eksalasi) can be shaped as follows:
a. fumarole gas
Namely the gas release water vapor (H2O).
b. gas sulfatar
Ie gas containing sulfur (H2S)
c. gas mofet
Ie a gas containing carbon dioxide.
