This is known as the focus or more correctly the hypocentre.


Which is more useful to scientists the Richter scale or Mercalli scale?

The scales have differing uses and so which scale is more useful depends on exactly what the scientist is interested in. The Richter scale is a magnitude scale. This is an estimate of the amount of energy released by an earthquake. The Mercalli scale is an intensity scale. This is an estimate of the perceived severity of ground shaking in differing areas caused by an earthquake. The Richter value is derived based on the amplitude of seismic waves measured on a seismometer and a single value is calculated for a given earthquake. This allows an earthquake to be compared to other earthquakes. The Mercalli intensity value is derived based on the damage caused to buildings and other structures and also based on the measured ground acceleration at a given location. This value can vary depending for a given earthquake on the local ground conditions, the distance from the earthquakes epicentre and the earthquake resistance of buildings. As such, the Richter value is most useful for comparing one earthquake with another, the Mercalli value is most useful for comparing the severity of ground shaking and damage caused by a single earthquake in different locations.


What name is given to sudden stress changes in the earth that cause ground shaking and occur at fault lines and near volcanic activity?

This is known as an earthquake or as seismic activity.


Is the magnitude of an earthquake same as its intensity?

No.The magnitude is a measure of the total energy released by an earthquake.The intensity is a measure of the violence of ground shaking at a particular point. This is based on the statements of witnesses, damage to buildings and the ground acceleration as measured by a seismometer. As such it varies from place to place for a given earthquake.


The amount of shaking produced by an earthquake at a given location is called?

The amount of shaking produced by an earthquake at a given location is called "intensity".


The amount of shaking produced by an earthquake at a given location is called the?

The amount of shaking produced by an earthquake at a given location is called the intensity. It is measured on the Modified Mercalli Intensity (MMI) scale, which quantifies the level of shaking experienced by people and structures during an earthquake.


What is the name of the earthquake that caused hati?

Earthquakes aren't given names, but they are given magnitudes, if that's helpful. The magnitude for the earthquake that caused the Hati disaster was 7.0.


What is earthquake intensity?

Earthquake intensity is measured using the modified Mercalli scale or the macroseismic scale. Their values are derived based on eye witness accounts of the violence of the shaking of the ground, the damage done to buildings and other structures and based on ground surface accelerations measured by seismometers.


Good Friday earthquake is a name given to?

The Good Friday earthquake is the name given to a powerful earthquake that occurred in Alaska on March 27, 1964. It remains the most powerful recorded earthquake in North American history and caused widespread damage and tsunamis.
