Earthquakes is one of the natural phenomena which is caused by imbalance in nature. Earth is composed of many layers, as we move towards the core the temperature increases and the molten state of matter is present. When there is even minor displacement in the inner layers of the earth, it results in movement of tectonic plates of the earth, which releases high level of kinetic energy waves capable of destruction as the plates move. These waves are measured in Richter scale that determines the energy carried by these waves. So movement of the base combined with energy waves released is term as earthquake, its derived from greek word quake which means shiver or wrath.

What is the term used to define the exact location of an earthquake?
epicenter
What is the mechanism of earthquake?
The animation on this page shows the main concepts that define a seismic event, as well as some of the consequent effects.
Where is an earthquake's focus located?
An earthquake's Focus is located directly under the Epicenter of an earthquake. The Epicenterof an earthquake is located on the surface of the earthquake.
What is the orgin of an earthquake called?
earthquake
What was the biggest earthquake in 2010?
The Chile Earthquake in February was the biggest earthquake reported in 2010.
Define Magnatude please?
severity-earthquake terrm
What is the term used to define the exact location of an earthquake?
epicenter
Define seismic safe?
Definition: structures that are resistant to vibrations during an earthquake:)
Define what is magnitude?
Magnitude: a measure of the strength of an earthquake. Hoped that helped ya😜
Define what is intensity?
Intensity - in Earth science, the amount of damage caused by an earthquake. Hope that helped 😘
What was the worst earth quake ever recorded?
Define "worst". The largest earthquake measured by seismograph was the 1960 Valdivia earthquake, with a magnitude of 9.5.The highest casualty total is from an earthquake in China in 1556, which killed over three-quarters of a million people.
Define major earthquake?
A country getting split in half. Buildings collapsing. A lot of People dying. Does that take care of it?
What is the mechanism of earthquake?
The animation on this page shows the main concepts that define a seismic event, as well as some of the consequent effects.
Can we define earthquakes as a horizontal force on crust at a particular point?
No. Earthquake forces can be horizontal, or nearly so, but they can also have a significant vertical component as well.
What definition of earthquake load?
In simple words, we can define it as``The total force exerted on a structure by an earthquake``. And in detail, ``The seismic loads on the structure during an earthquake result from inertia forces which were created by ground accelerations. The magnitude of these loads is a function of the following factors: mass of the building, the dynamic properties of the building, the intensity, duration, and frequency content of the ground motion, and soil-structure interaction``.
What value is used to define an earthquake as small on the moment magnitude scale?
The length of the fault rupture, the relative displacement of the fault and the elastic modulus of the rocks affected, where the smaller these values, the smaller the magnitude of the earthquake. Also the amplitude of seismic waves can be used to estimate the moment magnitude and the smaller the amplitude, the lower the magnitude.
What is used to determine the earthquakes intensity?
Seismologists estimate earthquake intensity based on the reports of witnesses on the level of felt ground movement, on the amount of damage caused by an earthquake and also based on the ground accelerations as measured by seismometers. The scale used to define earthquake intensity in much of the world is the Modified Mercalli scale (before this, a scale known as the Rossi-Forel scale was used). In Europe the Macroseismic scale is in use.
