WebModerate earthquake: An earthquake having a magnitude of 5 to 6 on the Richter scale. Modified Mercalli Intensity Scale: The Mercalli scale rates the intensity of shaking from an earthquake. The ratings vary from I (felt only under especially favourable circumstances) to XII (total destruction). Modified Mercalli (MM) Intensity Scale Web5.0–5.9. 401. 4.0–4.9. 3,447. ← 2024. This is a list of earthquakes in 2024. Only earthquakes of magnitude 6 or above are included, unless they result in significant damage and/or casualties. All dates are listed according to UTC time. The maximum intensities are based on the Modified Mercalli intensity scale.

Webearthquake will occur on one of the Bay Area’s faults before 2046. Magnitude is the most common measure of an earthquake's size. Magnitude measures the energy released at the source of the earthquake. Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people,
WebThe United States Geological Survey (USGS) describes it as an M8.3 event, and the Chinese Earthquake Administration assigns it closer to an 8.5. It was an extremely powerful quake and its observed effects corresponded to the maximum intensity of the Modified Mercalli Intensity Scale (XII). Figure 1.
