Modern geologists estimate that the 1755 earthquake reached 9 points in the Richter scale (the Haiti earthquake was 7 points). The earthquake was followed by a massive tsunami of 5 meters (15ft) high, and several fires that destroyed Lisbon almost to the ground.

What was the level of damage the Great San Francisco Earthquake of April 1906 on the Mercalli Scale?
MM Intensity- XI
What level of damage is caused by an earthquake with an intensity level of XII?
An earthquake with an intensity level of XII on the Modified Mercalli Intensity scale can cause total destruction in the affected area. Buildings, bridges, and infrastructure may collapse, resulting in widespread devastation. There may also be landslides, ground ruptures, and tsunamis triggered by such a powerful earthquake.
What was the intensity level of the new zealand earthquake?
It measured 6.3 on the Richter scale
What intensity of an earthquake when it is felt by several persons at rest?
It depends what location you are at, if your in a basic neighbourhood at sea level, an earthquake of about2.7-3.3.
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 measure of how much damage an earthquake causes the surface?
The measure of how much damage an earthquake causes on the surface is determined by the earthquake magnitude and the distance from the epicenter. Earthquake damage can also be influenced by local geology and infrastructure resilience. The Modified Mercalli Intensity (MMI) scale is commonly used to assess the level of shaking and resulting damage.
What was the mecalli scale level when the Kamchatka earthquake hit in 1952?
The Kamchatka earthquake of 1952, which occurred on November 4, registered a maximum intensity of VIII on the Modified Mercalli Intensity (MMI) scale. This level indicates significant damage, with many buildings experiencing severe shaking and structural impacts. The earthquake was notable for its size and the subsequent tsunami it generated, highlighting the region's seismic activity.
What was the Modified Mercalli scale level for the Chilean earthquake 2010?
According to the US Geological survey, the maximum intensity of the magnitude 9.5 Chilean earthquake of 1960 was rated as XI on the Modified Mercalli Intensity scale which are described as very disastrous or extreme events which are likely to cause significant damage to structures. Please see the related link for details.
What is intensity 6?
it is low...the lower the number the worse the earthquake.
Earthquake intensity is charted on a Richter scale on a scale of 1 to .?
The Richter scale measures the magnitude of an earthquake, not its intensity. The Richter scale ranges from 1 to 10, with each whole number increase representing a tenfold increase in amplitude of seismic waves. Each level on the scale corresponds to an increase in energy released by the earthquake.
Where did the Haitian earthquake hit the hardest?
The US Geological Survey provide a contour map of earthquake intensity for the earthquake that occurred on the 12th of January, 2010. This indicates that the highest intensity (perceived shaking) with a level of 10 (X) on the Modified Mercalli Intensity Scale occurred in Grand Goave (population 5000). The Haitian capital Port-au-Prince suffered an intensity 9 event. The scale indicates that at this intensity structures will suffer heavy to very heavy damage. Please see the related links and question.
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.
