Which earthquake scale would be most appropriate to describe historic earthquakes where seismograph records are not available?
The Mercalli intensity scale would be most appropriate for describing historic earthquakes where seismograph records are not available. This scale categorizes earthquakes based on the observed effects on people, buildings, and the environment rather than on instrumental measurements. It provides a qualitative description of the earthquake's intensity and impact.
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 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.
What kind of scale measures earthquakes according to the level of damage?
The Modified Mercalli Intensity (MMI) scale measures earthquakes based on the level of damage and the effects felt by people and structures. The scale ranges from I (least amount of damage) to XII (total destruction).
Is the modified mercalli scale still used today?
Yes, the Modified Mercalli Intensity (MMI) scale is still used today to measure the intensity of earthquakes based on observed effects on people, buildings, and the environment. It provides a valuable complement to seismic magnitude scales in assessing the impact of earthquakes on society.
What does the modified mercalli scale measure?
The Modified Mercalli Intensity scale is used to measure the intensity of an earthquake based on its observed effects on people, buildings, and the natural environment rather than the seismic energy. It provides a qualitative assessment of the shaking and damage caused by an earthquake at a specific location.
What is the highest intensity on the Modified Mercalli Intensity Scale?
11
What factors determine on 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 is the highest intensity level on the modified mercalli intensity scale?
11
What factors determined an earthquake's intensity on the modified Mercalli scale?

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.
Name the scale that measures the intensity of earthquakes?
The Rickter (RICK-tur) scale has been popular for decades to measure the intensity of earthquakes, yet it had its issues. These days the Mercalli scale is most often used by geologists and vulcanologists.
What factors determine an earthquale's intensity on the modifield Mercalli scale?
The factors that determine an earthquake's intensity on the Modified Mercalli Intensity Scale include the earthquake's magnitude, distance from the epicenter, local geology and ground conditions, and building structures. Intensity also depends on the impact of ground shaking, surface faulting, landslides, and other secondary effects.
What has the author Rutlage J Brazee written?
Rutlage J Brazee has written: 'Reevaluation of Modified Mercalli Intensity Scale for earthquakes using distance as determinant' -- subject(s): United States, Seismometry, Earthquakes
What intensity is there considerable damage to poorly built buildings?
An intensity of VII on the Modified Mercalli Intensity scale can cause considerable damage to poorly built buildings. This level of intensity typically leads to partial collapse of structures with a likelihood of extensive damage.

This scale categorizes earthquakes based on the observed effects on people, buildings, and the environment rather than on instrumental measurements.
