Earthquake intensity is measured using the modified Mercalli scale or the macroseismic scale. Their values are derived based on eye witness accounts of the violence of the shaking of the ground, the damage done to buildings and other structures and based on ground surface accelerations measured by seismometers.
An intensity 5 earthquake is considered moderate and can cause shaking that is felt by many people, potentially causing slight damage to buildings. In comparison, an intensity 7 earthquake is considered major and can cause widespread damage, including collapse of buildings and infrastructure. The shaking intensity and potential impact on structures and people are significantly higher in an intensity 7 earthquake compared to intensity 5.
A magnitude of 8.0 earthquake could be classified as a low intensity by descriptions of damage to buildings and terrain. The intensity is often greatest near the earthquakes epicenter.
Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified Mercalli intensity scale.
The intensity of an earthquake measures the effect of an earthquake
Earthquake magnitude and intensity are related but measure different aspects of seismic events. Magnitude quantifies the energy released at the earthquake's source, while intensity measures the effects of the earthquake at a specific location. Magnitude is a single number on a logarithmic scale, while intensity is based on observed shaking and damage. In general, higher magnitudes correspond to stronger earthquakes, but intensity can vary depending on factors like distance from the epicenter and local geology.

The seismic scale that measures the intensity of earthquake damage is called the Mercalli intensity scale. This scale measures the effect an earthquake has on people and surroundings.
A magnitude of 8.0 earthquake could be classified as a low intensity by descriptions of damage to buildings and terrain. The intensity is often greatest near the earthquakes epicenter.

The Phivolcs Earthquake Intensity Scale is used to measure the intensity of earthquakes in the Philippines, ranging from Intensity I (not felt) to Intensity X (damaging). It is a subjective scale based on observed effects on people, buildings, and the environment rather than on the magnitude of the earthquake itself.
According to the US Geological Survey, the 1906 earthquake reached a maximum intensity of 9 on the Modified Mercalli Intensity scale.
differences in earthquake intensity; differences in demographics at/near the earthquake site
It had an intensity of 8.1 on the Righter magnitude scale. As a means of comparison, it had an intensity of roughly 100 times than that of the 1989 Loma Prieta earthquake.
Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified Mercalli intensity scale.
the intensity was high reaching an 98 ftTsunami
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.
