Q & A
What is the main topic of the lesson in the transcript?
-The main topic is about natural hazards, mitigation, and adaptation, with a focus on geologic processes and hydrometeorological phenomena.
What are the two objectives of the lesson?
-The first objective is to describe the various types of hazards that may occur during earthquakes, volcanic eruptions, landslides, tropical cyclones, monsoons, floods, and more. The second is to use hazard maps to identify areas prone to these hazards.
What are the hazards brought by earthquakes according to the lesson?
-Earthquakes can cause hazards like damage or collapse of structures, fissures, liquefaction, landslides, and tsunamis.
How do volcanic eruptions pose a danger to communities?
-Volcanic eruptions release lava flow, ash clouds, fiery materials, and can trigger mudflows and fires, posing significant risks to nearby communities.
What are the effects of landslides as described in the lesson?
-Landslides can cause rockfalls, debris flows, and mudflows, moving rocks and debris from higher to lower areas, leading to erosion and destruction.
What are the hazards caused by tropical cyclones?
-Tropical cyclones cause hazards such as storm surges, flooding, high winds, extreme rainfall, landslides, and mudflows.
What are monsoons, and how do they affect the Philippines?
-Monsoons are seasonal weather patterns. The Philippines experiences the southwest monsoon, which brings heavy rains, and the northeast monsoon, which affects the weather during cooler months like December and January.
What are the main dangers associated with floods?
-Floods bring hazards like inundation, erosion, the movement of large particles, and can lead to drowning, electrocution, and infection.
How are 'ipoipo' and 'buhawi' different?
-An 'ipoipo' refers to a whirling wind formed over a water area, while 'buhawi' refers to a similar phenomenon but on land.
What is the final task given to students at the end of the lesson?
-Students are asked to reflect on how to minimize the damages caused by natural disasters and why preparedness is everyone's responsibility. They are instructed to write their insights in their learning packets.

🌋 Introduction to Natural Hazards and Objectives
The lesson focuses on natural hazards, particularly geologic processes and hydro-meteorological phenomena. The objectives include understanding the different types of hazards caused by earthquakes, volcanic eruptions, landslides, and tropical cyclones, and learning to identify hazard-prone areas using maps. The instructor starts by revisiting concepts of earthquakes and their effects, introducing the hazards they bring such as structural damage, fissures, liquefaction, landslides, and tsunamis.
⛈ Volcanic Eruptions, Landslides, and Cyclones
The paragraph covers the hazards related to volcanic eruptions, such as lava flows, ash clouds, and fiery materials that cause fires and destruction. It also explains landslides, which are common in the Philippines during heavy rains, and their associated hazards like rockfalls, debris flows, and mudslides. Finally, tropical cyclones and their destructive effects, including storm surges, flooding, and landslides, are discussed.
🌬 Monsoons, Floods, and Tornadoes
This section discusses the two monsoon systems in the Philippines: the southwest and northeast monsoons, which bring heavy rains and affect weather patterns. It also details the hazards of floods, such as erosion, drowning, and electrocution. The difference between tornadoes (ipo-ipo) and water spouts (buhawi) is explained, highlighting their formation and destructive potential.

[Music]
good day russians i'm mr olyssie franco
your instructor in earth and life
science this is another instructional
video for earth and life science week
two and now we're in unit number three
but before we start with our lesson
let's pray first
[Music]
in the name of the father and of the son
and of the holy spirit
amen
almighty father
being the true source of light and
wisdom grant us the grace of
understanding of knowledge and
enlightenment of mind for us to truly
understand the lessons
which are designed for us by our
teachers
with love and compassion

san lorenzo ruiz pray for us
jesus you are my lord my happiness lies
in you alone
in the name of the father and of the son
and of the holy spirit amen
[Music]
how are you today i hope that you and
your loved ones are in good condition
before we start with another lesson
let us recap what we have discussed in
our last video
our last topic is all about geologic
time skill we've discussed different
ways of dating and placing the different
events that happen during the past using
the relative and absolute dating and
also we focus on the phanerozoic eon or
the timeline of the different species
that occurred in the past time of our
earth
we have first the paleozoic era
or the early life which included the
cambrian or division silurian devonian
carbony peruse and permian period
we've discussed the mesozoic era or the
middle life which flourished the
reptiles and dinosaurs it included the
triassic jurassic and creatures period
and lastly we've discussed about
xenosovic era or the new life which
included the flourish of mammal life it
included the paleogene neogene and
quaternary peru
now we are going to ayun unit which is
unit number 3 but before we start with
our lesson i want you to get yourself
ready and have your learning packet with
you
now that you are ready let's start with
our lesson
now let's move on to unit number three
as part of our week number two which is
all about
natural hazards mitigation and
adaptation it includes two topics which
are first the geologic processes and
hydro meteorological phenomena and
hazards and the second one is the marine
and coastal processes and their effects
let us first discuss the first topic or
the first lesson the geologic processes
and hydro meteorological hazards and
phenomena
for this lesson we have two objectives
for objective number one we have
describe the various types of hazard
that may happen in the event of
earthquakes volcanic eruptions
landslides tropical cyclones monsoons
floods ipoipo or buhawi
and using hazard maps identify areas
that are prone to hazards brought about
by the earthquakes volcanic eruptions
landslides trophical cyclones monsoons
floods ecoepos or bohawis
let us first discuss earthquake you have
learned in your grade 8 science and
grade 10 science the different things
about earthquake which is all about its
strength which is measured by magnitude
and its effect which is measured through
intensity you've learned about different
things that causes earthquakes and that
it is not predicted and it may happen
all the time
but
now we will only discuss the hazards
that are brought by earthquake and other
uh geologic processes and hydro
meteorological phenomena later hazards
is all about the effects that is brought
by the aftermath of an earthquake
volcanic eruption etc
so that is the focus of our discussion
now for earthquake massive movement of
plates may result to damage or collapse
of structures fissures liquefaction
landslide and tsunami these are the
hazards that earthquake can brought to
our community supplying macaron and
damage
properties
that's
uh
tsunami because of underwater
earthquakes liquefaction
[Music]
and also fish
next we have volcanic eruption
volcanic eruptions brought different
enhancers as lava flow ash clouds
and then also it really says different
fiery materials
that may cause fires
and also
young muds or natal
hearts
to the community that is surrounding it
and aside from that
houses or structures within the danger
zone of the volcano
next one is the landslides very common
in our country when it comes to heavy
rain usually merong landslide
so it brings or it brought different
hazards such as rock falls or rock
slides debris flows and mud flows okay
so young landslide
rocks from higher surface to lower
surface so unless like i say it's a form
of erosion okay it's another erosion
movement of rocks or from one place or
from a higher place to a lower place
okay so another one is the bristles
individual
and mud floors
another hazard
community
next one is the trophical cyclone so or
not in baguio did some filipinas
it causes different hazards such as
storm surge flooding strong or high
winds extreme rainfall swirls landslides
and mud flows
so undamaging effects
been abroad about non-tropical cyclones
[Music]
rainfall but
that will lead to flooding landslides
and mud flows
next one is the monsoons
it is a seasonal
partnership weather and appliance
monsoon we have two monsoons in the
philippines and
in weather systems we have the southwest
monsoon and the northeast monsoon
southwest monsoon is responsible for
heavy rains
[Music]
december or january
next one is the plants floods or
it brought different hazards or it
brings different hazards such as
inundation erosion movement of large
particles drowning electrocution and
infection
or itchiness or skin
movement of large particles also may
also be the one of the hazards brought
by the floods
and lastly
let us first differentiate what is ipo
and buhawi when we say
it is whirling of winds
produced or formed
above a water area
process and natural geologic process and
hydro meteorological phenomena
so now if you want to learn more about
this lesson you can open the file nueva
c hazards map and philippine hazards map
parameters
geologic and hydro meteorological
processes
now before we finally end this lesson i
want you to answer the values
integration on your learning packet
which is here our country is located
just above the filipino plate or the
pacific ring of fire where most
earthquake and volcanic eruptions occur
along the mountain
true solidarity our one of our core
values how can we minimize the damages
brought by these natural disasters
and why is the story preparedness
everyone's responsibility
think about it write your insights about
this values integration on your learning
packet
now it's time for us to check how you
understand our lesson but if you still
have questions in your mind you can
contact me during our consultation hours
let's check your understanding answer
activity 3 on your assessment sheets
that's it for our
[Music]
you
