The Complete Guide to Earthquakes, Tsunami and Volcanoes
Introduction: Introduction to Earthquakes, Tsunami and Volcanoes
Earthquakes, tsunamis, and volcanic eruptions are all natural disasters that can cause a lot of destruction to any area they affect. This guide will explain what causes these natural disasters and how to be prepared for them.
What Causes Earthquakes?
Earthquakes are caused by the earth’s tectonic plates shifting. The plates move because they are being pushed together or pulled apart. When two plates push together it creates a mountain range, when two plates pull apart it creates a valley. The earth’s crust is made up of many tectonic plates that constantly move and create earthquakes in different places around the world.
Volcanic Eruptions
Volcanic eruptions happen when magma from deep within the earth rises to the surface and explodes out
Types of Earthquakes, How They Form And What Causes Them?
Earthquakes are one of the most destructive natural disasters that can happen anywhere in the world. They can cause serious damage, injury, and death. There are many different types of earthquakes and they have different causes.
The most common type of earthquake is a "tectonic" earthquake. These earthquakes happen when there is a sudden slip between two sides of a fault, which are called tectonic plates. Another type of earthquake is an "intraplate" earthquake that happens when the Earth's crust stretches or shrinks in response to changes in temperature or pressure.
There are many factors that contribute to the development of an earthquake and their intensity:
-Earthquake depth
-Distance from Earth's surface
-Intensity at which it is struck by seismic waves
Effects of Earthquakes & What to do When One Occurs?
Earthquakes are natural disasters that can cause the ground to shake and tremble, leading to loss of life, property damage, and social disruption.
In this article, we will discuss what causes earthquakes, the effects of earthquakes on people and property, and what you should do when an earthquake occurs.
Earthquakes are caused by a sudden release of energy in the Earth's crust that creates seismic waves. The most common cause is movement along a fault line. Earthquakes can also be caused by landslides or volcanic eruptions.
The effects of an earthquake depend on the magnitude of the earthquake and its proximity to people or infrastructure such as buildings. The deadliest earthquakes happen in densely populated areas like Tokyo or Mexico City where there is significant damage to buildings and infrastructure.
When an earthquake occurs:
Tectonic Plates – Cause of Earthquakes & Tsunamis?
Tectonic plates are large pieces of the Earth's crust that move around. They are also known as lithospheric plates and play a major role in the formation of earthquakes and tsunamis.
The tectonic plates have been continuously moving for billions of years. They move at a rate of about 2-5 cm (1 in) every year, but can also be more than 10 cm (4 in) per year when they are near fault lines.
Tectonic plates cause earthquakes by colliding with each other, which leads to the formation of mountain ranges and volcanoes. Earthquakes can be caused by sudden movements within tectonic plates as well, which is called intraplate seismicity or intraplate deformation.
