Meanwhile, major earthquakes such as the 1994 offshore Sanriku earthquake and the 1995 Great Hanshin Earthquake revealed issues like wide variability in damage in areas with intensities 5 and 6, as well as delays in determining intensity 7 (which required field surveys by the JMA’s mobile observation team). These issues highlighted the need ...
Much of an earthquake's total energy as measured by M w is dissipated as friction (resulting in heating of the crust). [52] An earthquake's potential to cause strong ground shaking depends on the comparatively small fraction of energy radiated as seismic waves, and is better measured on the energy magnitude scale, M e. [53]
October 15, 2020, an earthquake swarm occurred on the island of Panay ranging from magnitudes 2.5-4.5. Most of these quakes felt in Iloilo City. [11] A previous swarm also hit Panay on November 5, 2018 (Including Antique, Iloilo and Guimaras) ranging from magnitudes 4.0-4.8. The first earthquake (magnitude 4.7) at 7:45 A.M, occurred at San Jose ...
The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. (The "M w" scale is ...
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

In southern California about 6% of M≥3.0 earthquakes are "followed by an earthquake of larger magnitude within 5 days and 10 km." [12] In central Italy 9.5% of M≥3.0 earthquakes are followed by a larger event within 48 hours and 30 km. [13] While such statistics are not satisfactory for purposes of prediction (giving ten to twenty false ...
The Weather Channel was founded on July 18, 1980, [9] by television meteorologist John Coleman (who had served as a chief meteorologist at ABC owned-and-operated station WLS-TV in Chicago and as a forecaster for Good Morning America) and Frank Batten, then-president of the channel's original owner Landmark Communications (now Landmark Media Enterprises).
