What Is Earthquake In Your Own Words?

, , , ,

An earthquake is the result of a sudden release of stored energy in the Earth’s crust that creates

seismic waves

. Earthquakes are accordingly measured with a seismometer, commonly known as a seismograph.

What is earthquake in simple words?

An earthquake is

the sudden movement or trembling of the Earth’s tectonic plates

, that creates the shakes of the ground. This shaking can destroy buildings and break the Earth’s surface. Sudden shake under water is called tsunami. Earthquakes are caused by disturbances in the balance of the earth.

What is earthquake one word answer?

Earthquake,

any sudden shaking of the ground caused by the passage of seismic waves

through Earth’s rocks. … The major fault lines of the world are located at the fringes of the huge tectonic plates that make up Earth’s crust.

What is earthquake summary?

Summary. An earthquake

happens when two blocks of the earth suddenly slip past one another

. Earthquakes strike suddenly, violently, and without warning at any time of the day or night. If an earthquake occurs in a populated area, it may cause property damage, injuries, and even deaths.

What are the 10 causes of earthquake?

  • Groundwater extraction – decrease in pore pressure.
  • Groundwater – increase in pore pressure.
  • Heavy rain.
  • Pore fluid flow.
  • High CO2 pressure.
  • Building dams.
  • Earthquakes.
  • No earthquakes (Seismic quiescence)

How does an earthquake start?

An earthquake is

caused by a sudden slip on a fault

. … When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. In California there are two plates – the Pacific Plate and the North American Plate.

What is the best definition of earthquake?

Earthquake is a term used to describe

both sudden slip on a fault

, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth.

What is the name of earthquake?

An earthquake (also known as a

quake

, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth’s lithosphere that creates seismic waves.

What are types of earthquake?

There are four different types of earthquakes:

tectonic, volcanic, collapse and explosion

. A tectonic earthquake is one that occurs when the earth’s crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.

What is earthquake and its effects?

The primary effects of earthquakes are

ground shaking, ground rupture, landslides, tsunamis, and liquefaction

. Fires are probably the single most important secondary effect of earthquakes.

What are the 5 causes of earthquake?

  • Volcanic Eruptions. The main cause of the earthquake is volcanic eruptions.
  • Tectonic Movements. The surface of the earth consists of some plates, comprising of the upper mantle. …
  • Geological Faults. …
  • Man-Made. …
  • Minor Causes.

How does earthquake affect us?

Earthquakes usually

cause severe damage to urban centres

, resulting in the loss of life and damage to homes and other infrastructure. Although risks are normally associated with cities, the effects on the rural sector and farming communities can be devastating.

What are the 4 causes of earthquakes?

  • Induced Earthquakes. Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.
  • Volcanic Earthquakes. …
  • Collapse Earthquakes.

What are the symptoms of earthquake?

A large earthquake far away will

feel like a gentle bump

followed several seconds later by stronger rolling shaking that may feel like sharp shaking for a little while. A small earthquake nearby will feel like a small sharp jolt followed by a few stronger sharp shakes that pass quickly.

What are the warning signs of earthquakes?

Method 1 of 3:

Earthquake lights have been observed as short,

blue flames coming up from the ground

, as orbs of light that float in the air, or as huge forks of light that look like lightening shooting up from the ground.

What is the common cause of earthquake?

Earthquakes are usually caused

when underground rock suddenly breaks and there is rapid motion along a fault

. This sudden release of energy causes the seismic waves that make the ground shake.
