ERUPTION TYPES
Volcanoes can erupt with massive force, a small explosion,
or even just a steady dribble. The way each volcano erupts depend on how thick its magma is and how much gas is in the magma. In a gas -rich magma, violent expansion of bubbles can shatter the magma and project volcanic ash into the sky with huge force, creating an ash cloud . More gentle eruptions feed lava flows that ooze slowly down the side of the volcano.
PLINIAN
The most explosive and violent type of eruption .A steady powerful stream of gas and magma is blasted into the air.
VULCANIAN
A violent eruption that begins with a cannon -like explosion .
Lumps of rock called "bombs" are thrown out.
STROMBOLIAN
Short and explosive eruption that creates showers of cinders and lava bombs.
HAWAIIAN
Usually mild eruption that create fountains and stream s of runny lava .
FISSURE OR ICELANDIC
These are quiet , without loud explosions. They happen along long cracks in the ground .
