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 are Mercalli waves?
Mercalli waves refer to a subjective scale used to measure the intensity of an earthquake by assessing its effects on people, structures, and the environment. It is based on observations and reports of damage and is used to complement the more scientifically precise Richter scale measurement of earthquake magnitude.
What is the earthquake measurement?
There are two instruments, which are basically the same thing. There is the seismograph , and a more specific tool measures the waves on what is called the Richter scale. Earthquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.
What did the 2011 earthquake in tohoku japan measure on the mercalli scale?
The 2011 earthquake in Tohoku, Japan measured at a Mercalli intensity of VII (Very strong). The Earthquake had a magnitude of 9.0 and led to widespread damage and casualties.
How is it possible for an earthquake to measure relativey high on the Mercalli scale but measures low on the Richter scale?
An earthquake can measure relatively high on the Mercalli scale but low on the Richter scale due to the Mercalli scale's focus on the effects and damage caused by the quake rather than its energy release. For example, an earthquake may have a low magnitude but occur in a densely populated area, leading to significant destruction and high intensity ratings on the Mercalli scale. Factors such as local geology, building structures, and distance from the epicenter also influence perceived intensity, making it possible for the Mercalli rating to be high despite a low Richter measurement.
What is a intensity scale?
Mercalli is a scale for the measurement of earthquake intensities.
What was the mercalli scale for the Kobe earthquake?
The Mercalli Intensity Scale is a measure of earthquake intensity experienced at a given location. The Kobe earthquake in 1995 had intensities reaching up to VIII (8) on the Mercalli Intensity Scale in the heavily affected areas around Kobe.
What was the mercalli scale in Sichuan earthquake?
The Mercalli intensity scale measures the intensity of shaking and damage caused by an earthquake. The intensity of the Sichuan earthquake in 2008 was estimated to be around VII to IX on the Mercalli scale, indicating severe to violent shaking that led to widespread damage and casualties in the region.
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 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 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 does the mercalli intensity scall measure?
The effects of an earthquake on people and buildings.
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.
Which earthquake intensity scale assesses the effects of an earthquake on humans and human-made structures?
Mercalli scale

It is based on observations and reports of damage and is used to complement the more scientifically precise Richter scale measurement of earthquake magnitude.
What was the intensity of the 1906 San Francisco earthquake?
According to the US Geological Survey, the 1906 earthquake reached a maximum intensity of 9 on the Modified Mercalli Intensity scale.
