The world’s earthquake are not randomly
distributed over the Earth’s surface. They tend to
be concentrated in narrow zones

MEET
c. Look at your world map and compare the earthquake
epicenters. Name the country/ies where earthquakes may not
happen.
Answers may vary:Central Australia, Sahara Desert Countries,
Interior of South America, Interior of North America, Siberia
(Russia)

18. REMEMBER WHERE THE EDGES
MEET
d. Why are there no earthquakes on the country/ies you
mentioned?
A. Tectonic Plate Location: These countries are situated on stable
sections of tectonic plates, away from the boundaries where
most tectonic activity occurs.
B. Distance from Plate BoundariesCountries far from these plate
boundaries, like those in the Middle East and North Africa,
experience fewer seismic events because they are farther from
the primary sources of tectonic stress

42. SURPRISING FACTS
The majority of Earth's volcanoes are located
underwater, along mid-ocean ridges. These underwater
eruptions are often not as widely known as their
terrestrial counterparts.
During some volcanic eruptions, lightning can occur
within the ash clouds. This phenomenon is known as
"dirty thunderstorms" and is a spectacular but
dangerous aspect of volcanic activity.

43. SURPRISING FACTS
Massive volcanic eruptions can inject large quantities
of ash and gas into the stratosphere, causing a
temporary cooling effect on the Earth's climate. One
such event, the eruption of Mount Tambora in 1815,
led to the "Year Without a Summer" in 1816.-Volcanic
Winter

44. SURPRISING FACTS
The seismograph, an instrument used to detect and
record earthquakes, was invented by the Chinese
polymath Zhang Heng in 132 AD. It was a remarkable
advancement in earthquake science for its time.
The most powerful earthquake ever recorded occurred in
Chile in 1960. It had a magnitude of 9.5 on the Richter
scale and caused widespread devastation.

45. SURPRISING FACTS
The Moon also experiences quakes, known as
"moonquakes." These are primarily caused by the
gravitational interactions between the Earth and
the Moon.

46. SURPRISING FACTS
The Himalayas, home to Mount Everest, the world's
tallest mountain, continue to rise about 2.4 inches (6.1
cm) higher each year due to tectonic activity.
The Andes in South America is the longest mountain
range in the world, stretching for about 4,300 miles
(7,000 kilometers) along the western edge of the
continent.

47. DEFINITION OF TERMS
Fact about the Cordillera Mountains in the
Philippines is that they are home to the world-
renowned Banaue Rice Terraces. These terraces
are often referred to as the "Eighth Wonder of the
World" and are believed to be over 2,000 years
old.

volcanic eruptions. Make sure to enumerate specific
steps to achieve your goals or suggestions.

67. PERFORMANCE TASK
Use the hashtags: #youthinaction,
#disasterpreparedness. You may also mention or
paste/draw pictures of disaster hazards you have

71. WORDS TO PONDER
Even with all our technology and the
inventions that make modern life so much
easier than it once was, it takes just one
big natural disaster to wipe all that away
and remind us that, here on Earth, we're
still at the mercy of nature.
