1. TYPES OF VOLCANIC
ERUPTION

2. 1. Phreatic eruption
(steam-blast) occurs when'
heated rocks collide with water. It's a
short-lived'
eruption with ash clouds, but'
it could be the start of a major
eruption.'

3. Phreatic
eruption

4. 2. Phreatomagmatic eruption
are violent eruptions that occur when'
water and'
magma come into contact. As a result, a'
massive cloud of very fine ash and'
high-speed, sideways pyroclastic'
emissions known as "base surges" can be'
seen.

5. Phreatomagmatic
eruption

6. 3. Strombolian eruption
are periodic weak to violent
eruptions characterized by
lava fountains.

7. Strombolian
eruption

8. 4. Vulcanian eruption
such as those of Mexico's Paricutin'
Volcano, are
distinguished by tall eruption'
columns reaching up to 20'
kilometers in height,'
accompanied by pyroclastic flow'
and ashfall tephra.'

9. Vulcanian
eruption

10. 5. Plinian eruption
are excessively explosive
types of eruptions of gas and
pyroclastic, just like our
Pinatubo Volcano in
Zambales.
