5. Phreatic or hydrothermal
√ An eruption driven by the
hot rocks interacting with
water.
√ Phreatic eruptions
pulverize surrounding rocks
and can produce ash.
12. Strombolian
√ The least violent types of
explosive eruptions.
√ Strombolian eruptions have
explosions causing a shower
of lava fragments.
13.
14. Taal
January 31, 1968; October 29, 1969
The only Strombolian eruptions of
Taal Volcano were recorded on these
dates, which both happened at the Mt
Tabaro crater.
18. Plinian
√ The most explosive and
largest type of volcanic
eruptions of gas and
pyroclastics.
√ Plinian eruptions have
20 to 35 km tall columns .

20. Taal Volcano
May 15 to December 5, 1754
This incident is considered Taal Volcano’s
biggest eruption yet and lasted almost 7 months. It
buried 4 towns in Batangas under ash, volcanic
rocks, and water.
Pinatubo Volcano
1991- Jun 9- Sept 4.
Mayon Volcano
1814 Feb 1
24. IDENTIFICATION
Directions: Read carefully and answer the following.
1. A type of eruption that is driven by the heat from magma interacting with
water.
2. This type of eruption is small to moderate explosive eruptions, that are
lasting seconds to minutes.
3. A type of an eruption thatresulting from the interaction of new magma or
lava with water and can be very explosive.
4. It is the most explosive and largest type of volcanic eruptions with a high
rate of magma discharge sustained for minutes to hours.
5. These type of eruption are the least violent and have fire fountains and
lava flowsor have explosions causing a shower of lava fragments.
