v. t. e. 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 " Mw ...
t. e. Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales, which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking.
James Hutton FRSE (/ ˈ h ʌ t ən /; 3 June O.S. [1] 1726 – 26 March 1797) was a Scottish geologist, agriculturalist, chemical manufacturer, naturalist and physician. [2] Often referred to as the "Father of Modern Geology," [3] [4] he played a key role in establishing geology as a modern science.
The earthquake was 6.5 on the M w scale, with a maximum perceived intensity of IX (Violent) on the Mercalli intensity scale. However, most of the intensity measurements were consistent with an overall maximum intensity of VII ( Very strong ), and only the damage to a single structure, the Imperial County Services building in El Centro , was ...
Magnetic potential map of the Reelfoot Rift. The New Madrid Seismic Zone (NMSZ), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
The 2010 Haiti earthquake was a catastrophic magnitude 7.0 M w earthquake that struck Haiti at 16:53 local time (21:53 UTC) on Tuesday, 12 January 2010. [ 8 ][ 9 ] The epicenter was near the town of Léogâne, Ouest department, approximately 25 kilometres (16 mi) west of Port-au-Prince, Haiti's capital. By 24 January, at least 52 aftershocks ...
Giuseppe Mercalli (1850–1914) – priest, volcanologist, and director of the Vesuvius Observatory who is best remembered today for his Mercalli scale for measuring earthquakes which is still in use; Marin Mersenne (1588–1648) – Minim philosopher, mathematician, and music theorist, so-called "father of acoustics"
Seismology (/ saɪzˈmɒlədʒi, saɪs -/; from Ancient Greek σεισμός (seismós) meaning " earthquake " and -λογία (-logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through the Earth or other planetary bodies.
