WebEarthquakes in the prominent seismic zones described above are taken for granted, but damaging shocks can occur outside these zones. 3 earthquakes in the past 365 days. an increase by 1 magnitude step stands for a 10-fold increase in shaking), still widely used, especially by news media, but gradually replaced by moment magnitude, Richter magnitudes depend on regional geology, scale saturates for large earthquakes and does not account for prolonged shaking during very large earthquakes, most recent scale, introduced by Kanamori, measure for energy released by an earthquakes (given in Nm), on this scale, the largest four earthquakes in the last 100 years have the following moment magnitudes: 1960 Chile (9.5); 1964 Alaska (9.2); 1957 Alaska (9.1); 2004 Sumatra-Andaman (9.0), this scale is now used in most publications (that news media get their info from), about 3.5 Mio earthquake/year worldwide (Table 5.5). oceanic plate sinks beneath another plate (oceanic or continental), subduction zones are usually the location of the largest and most damaging earthquakes, convergent plate boundaries are often long, allowing earthquakes to grow to large sizes, three depth ranges of EQs: shallow (< 100km), intermediate (100-300km), deep (> 300km), shallow EQs along seafloor trenches (NB: trench bottom as deep as 11 km below sea level), intermediate and deep EQs occur in the subducting plate behind trenches, on the side of overriding plate, in a down-dipping band (, the Wadati-Benioff zone therefore traces the sinking slab, EQs occur mostly near the top of the subducting slab, EQs to a depth of about 500km are a results of brittle failure, below this depth, heated subducted plates become too ductile for EQs to occur, deeper EQs occur as result of phase transformation of crust and mantle rock, deepest EQs occur to a maximum depth of 670km, fault plane: a contact zone between two blocks (or plates) along which an earthquake occurs, fault (or fault trace): the surface expression of a fault plane, hanging wall: wall or block above the fault plane, foot wall: wall or block below the fault plane, hypocenter (focus): the point where an earthquake initiates; link to, epicenter: the surface location of the hypocenter; link to, source time: time of the initial rupture of an earthquake, seismic moment: amount of energy released during an earthquake (measured in Nm), rupture area: the part of a fault plane that actually ruptures during a particular EQ; On the 32nd anniversary of that earthquake, another one centered about 100 miles southeast rocked the city, killing more than 155 people, including dozens of children inside a schoolAlberto Briseo, a 58-year-old bar manager, said at the time, The scariest part of it all is that if you are an adult, and youve lived in this city your adult life, you remember 1985 very vividly..

Chile 1960; Sumatra 2004), in cont-cont collision zones, the Wadati-Benioff zone may no longer be seismically active. Follow the. every 1/210 years = 0.00476 years, or 1.74 days (0.00476*365), => a magnitude 0.0=1.9 EQ happens every 10.5s; a mag 8.5 or larger EQ happens only every 3.3 years, EQs do not occur regularly (i.e. Some hours later, Ms. Bernal said she had been debating whether to serve people again, and had decided that it was safe to do so.
