Question

A. Which regions are high-risk (darkest shade) in terms of:

1) earthquakes?
2) landslides?
3) volcanic eruptions?
4) tsunamis?​

Answer 1

Answer:

Earthquakes:japan,tonga,fiji,indonesia,china,iran

Landslides:The cordillera region has the highest risk of landslides in the philippines

Volcanic eruptions:Indonesia,philippines,japan,mexico,ethiopia,guatemala,ecuador,itlay,elsalvador,kenyo

tsunamis: IDK

it's help?!

Answer 2

In terms of option 1)earthquakes, 3)volcanic eruptions, and 4) tsunamis, regions are at high risk (darkest shade). Natural disasters such as earthquakes, tsunamis, and volcanic eruptions pose a high danger in the Asia-Pacific region.

Explanation:

Earthquake

• Earthquakes are caused by sudden changes along with fault lines in the Earth's crust.
• The movement releases accumulated 'elastic strain' energy in the form of seismic waves, which travel through the Earth and shake the ground surface.
• This tremor has the potential to demolish structures and breach the Earth's surface.
• Seismology is the study of earthquakes' causes, repetitions, types, and sizes.
• Seismographs are used to determine the magnitude of earthquakes.

Volcanic eruptions

• When magma, or molten rock, rises to the surface, volcanoes erupt. When the earth's mantle melts, magma is created.
• Another way an eruption occurs is when water beneath the surface reacts with hot magma and produces steam, which can build-up to the point of causing an explosion.

Tsunamis

• A tsunami is a succession of waves triggered by earthquakes or volcanic eruptions under the sea.
• A massive earthquake in the Southern Pacific Ocean triggered the tsunami.
• Tsunamis are massive waves that occur under the sea as a result of earthquakes or volcanic eruptions.

Landslides

• The movement of rock, soil, or debris down a sloped area of the terrain is known as a landslide.
• Rain, earthquakes, volcanoes, and other elements that make the slope unstable produce landslides.
• Landslides are one sort of mass wasting, according to geologists, who study the physical formations of the Earth.
