Self Learnig Module 3
Active and Inactive Volcanoes
Introductory Message
For the Facilitator:
Welcome to the Science 9 Self-Learning Module on Active and Inactive volcano.
This Self-Learning Module was collaboratively designed, developed and reviewed by
educators from the Schools Division Office of Pasig City headed by its Officer-inCharge Schools Division Superintendent, Ma. Evalou Concepcion A. Agustin, in
partnership with the City Government of Pasig through its mayor, Honorable Victor
Ma. Regis N. Sotto. The writers utilized the standards set by the K to 12 Curriculum
using the Most Essential Learning Competencies (MELC) in developing this
instructional resource.
This learning material hopes to engage the learners in guided and independent
learning activities at their own pace and time. Further, this also aims to help learners
acquire the needed 21st century skills especially the 5 Cs, namely: Communication,
Collaboration, Creativity, Critical Thinking, and Character while taking into
consideration their needs and circumstances.
In addition to the material in the main text, you will also see this box in the
body of the module:
Notes to the Teacher
This contains helpful tips or strategies that
will help you in guiding the learners.
As a facilitator you are expected to orient the learners on how to use this
module. You also need to keep track of the learners' progress while allowing them to
manage their own learning. Moreover, you are expected to encourage and assist the
learners as they do the tasks included in the module.
For the Learner:
Welcome to the Science 9 Self-Learning Module on Active and Inactive volcano.
This module was designed to provide you with fun and meaningful opportunities for
guided and independent learning at your own pace and time. You will be enabled to
process the contents of the learning material while being an active learner.

LESSON
Figure 1. Mt. Pinatubo Eruption
Volcanic eruption is a natural
phenomena which happens when lava
and gas are discharged from a volcanic
vent. Volcanic eruption can cause
damages to properties, crops, and
people. It is one of the most destructive
calamity that could happen. Some of
its common manifestations are ash fall,
lahar, lava flow, ash cloud emissions or
combination of those.
One of the most destructive eruption that ever happened in the Philippines is
the 1991 Mt. Pinatubo Eruption, which is caller as one of the most powerful and
well-documented eruption of the 20th century. When it erupted last 1991, it spewed
out 10 billion tons of magma and ash, and 20 million tons of sulfur dioxide. The
resulting ash fall buried some parts of Pampanga under 10 feet of ash. This eruption
is also said to cause a global cooling of temperature of about 0.5 degrees celsius.
Our country has more than a hundred volcanoes as of 2013.There are several
ways by which volcanoes can be classified. PHIVOLCS, have adapted a system where
the Philippine volcanoes as Active or Inactive.
Active Volcano
An active volcano is a volcano that has had at least one eruption during the past
10,000 years. An active volcano might be erupting or dormant. An
erupting volcano is an active volcano that is having an eruption... A
dormant volcano is an active volcano that is not erupting, but supposed to erupt
again. There are twenty-three active volcanoes in the country according to
PHIVOLCS.

Inactive Volcano
An inactive volcano is one that could erupt but has not erupted for more than
10,000 years. Inactive volcanoes are also called extinct or sleeping volcanoes.
Inactive volcanoes are expected to erupt again at some point, despite being dormant
for thousands of years. Volcanoes with no record of eruptions are considered
as extinct or inactive. Their physical form since their last activity has been altered
by agents of weathering and erosion with the formation of deep and long
gullies. Inactive does not necessarily indicate the volcano will not erupt again. One
example is Mount Pinatubo had no recorded historical eruption before its
cataclysmic 1991 eruption.
