epicenter

focus

Richter scale
sending ash, gas and magma high up into the atmosphere
explosive volcano
Because the composition of magma is different in different volcanoes, the properties of the lava are different. In effusive eruptions, lava flows are relatively calm and do not explode out of the volcano.
nonexplosive volcano
a volcanic island situated in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung
Krakatoa
