The modified Mercalli Intensity Scale measures the effects of an earthquake based on observations and experiences rather than seismic data. For the significant Alaskan earthquake that occurred on March 27, 1964, which was a magnitude 9.2 event, the modified Mercalli intensity reached as high as XI (Extreme) in some areas. This indicated severe damage, with buildings destroyed, ground fissures, and significant changes to the landscape. The intense shaking was felt across a wide region, affecting various communities and leading to widespread destruction.

What was the modified mercalli scale reading in the Peru earthquake 2007?
the modified mercalli scale was VII-VIII
What was the Modified Mercalli Intensity scale value for the last earthquake in New Zealand?
The maximum measured intensity of the 2010 Canterbury earthquake in New Zealand was IX (9) on the Modified Mercalli scale.
What scale is used to record the damage caused by an earthquake?
The Modified Mercalli scale or in Europe, the Macroseismic Scale.
What was the modified mercalli scale level for the san Fran earthquake in 1906?
About no. 9
What measures an earthquake's intensity based on the observed effects on people and structures?
Richter scale, Modified Mercalli scale, Centigrade scale, and the Moment Magnitude scale
What is the difference in earthquake measurement by the Richter scale vs the Modified Mercalli Intensity Scale?
The Richter scale determines earthquake magnitude by measuring how much the ground moves, and the Modified Mercalli Intensity Scale determines earthquake intensity based on damage to buildings and effects on humans.
What factors determined an earthquake's intensity on the modified Mercalli scale?
The Modified Mercalli Intensity scale is used in the US to determine the severity of earthquake effects. Intensity ratings are in Roman numerals, I - meaning no people felt movement, all the way up to XII - where almost everything is destroyed.The amount of structural and geological damage done by an earthquake in a specific location determines an earthquake's intensity on the Mercalli scale. :)

What scale is used by PAGASA to measure the intensity of an earthquake?
PAGASA uses the Modified Mercalli Intensity (MMI) scale to measure the intensity of an earthquake in the Philippines. This scale assesses the effects of an earthquake on people, structures, and the environment rather than measuring the actual energy released by the earthquake.
Why is the Richter scale and the modified mercalli intensity scale different?
The Richter scale measures the magnitude of an earthquake based on the seismic energy released at its source, providing a single value that quantifies its strength. In contrast, the Modified Mercalli Intensity Scale evaluates the effects of an earthquake on people, buildings, and the Earth's surface, assigning intensity levels based on observations and experiences. While the Richter scale offers a scientific measurement, the Modified Mercalli scale reflects the earthquake's impact and perception, which can vary by location and distance from the epicenter.
What is the modified Mercalli scale measure?
modified mercalli scale measure is type of seismograph that they made in the 1989
What scale describes the effects of an earthquake on people buildings and land at a given location?
The Modified Mercalli intensity scale (or the Macroseismic scale in Europe).
