The Modified Mercalli Intensity (MMI) scale for the 2004 Sumatra earthquake, which struck on December 26, was reported to be as high as IX (Violent) in some areas, indicating widespread damage. This scale measures the effects of an earthquake based on human observation and structural damage rather than seismic data. The earthquake, with a magnitude of 9.1, caused significant destruction and loss of life across multiple countries, particularly in Indonesia, Sri Lanka, and Thailand. The intense shaking and subsequent tsunami resulted in catastrophic impacts, further underscoring the severity of the event.

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.
