A modified Mercalli intensity scale is used to quantify the earthquake's effects. That's why you can't directly convert the Richter or Magnitude scale to the Mercalli scale — although the released energy, local geology, terrain, depth of an earthquake and distance from the epicenter are all still the same. Thus, the Mercalli scale describes ...At 08:43 AM Philippine Standard Time (PST) of 27 July 2022 (Wednesday), a major Magnitude (M w) 7.0 earthquake shook the provinces in northwestern Luzon and adjacent areas including Metro Manila. The earthquake has an epicenter located 17.64°N, 120.63°E - 003 km N 45° W of Tayum (Abra) and a depth of 17 kilometers.Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are.

They use a device called a seismograph to measure the size of the waves. The size of the waves is called the magnitude. To tell the strength of an earthquake scientists use a scale called the Moment Magnitude Scale or MMS (it used to be called the Richter scale).The calculation of earthquake size using this scale is based on earthquake seismic movement rather than the amplitude of seismic waves recorded by a seismograph. The moment magnitude scale is the only reliable scale, capable of measuring the largest and the destructive earthquake (that is greater than magnitude 8).Prior to the development of the magnitude scale, the only measure of an earthquake's strength or "size" was a subjective assessment of the intensity of shaking observed near the epicenter of the earthquake, categorized by various seismic intensity scales such as the Rossi-Forel scale. ("Size" is used in the sense of the quantity of energy ...
