Recurrence Statistics of Great Earthquakes
We investigate the sequence of great earthquakes over the past century. To examine whether the earthquake record includes temporal clustering, we identify aftershocks and remove those from the record. We focus on the recurrence time, defined as the time between two consecutive earthquakes. We study the variance in the recurrence time and the maximal recurrence time. Using these quantities, we c...
متن کاملTectonic position of the Khailino and Olyutorka earthquakes
[1] The continentocean transition zone has various exogenous and endogenous processes that reflect the geodynamic ecological function of lithosphere. The East Kamchatka suffers the earthquakes with MSK64 over 9 points. PetropavlovskKamchatsky is in zone of 9.5 points. The area of strong earthquakes included the Hailinskoye (1991) the Olyotorskoye (2006) events with both magnitudes 7.1 that caus...
متن کاملHow many great earthquakes should we expect?
G reat earthquakes of magnitude 8.5 or larger occur infrequently. For a nearly 40-y period after the February of 1965 M 8.7 Rat Islands, Alaska earthquake, the world did not experience a single great earthquake; however, in the 7 y since late December of 2004, there have been a barrage of five great earthquakes. These earthquakes include the 2004 M 9.1 Sumatra, Indonesia earthquake; the 2005 M ...
متن کاملThe energy release in great earthquakes
The conventional magnitude scale M suffers saturation when the rupture dimension of the earthquake exceeds the wavelength of the seismic waves used for the magnitude determination (usually 5-50 km). This saturation leads to an inaccurate estimate of energy released in great earthquakes. To circumvent his problem the strain energy drop W (difference in strain energy before and after an earthquak...
متن کاملRepeating deep earthquakes: evidence for fault reactivation at great depth.
We have identified three groups of deep earthquakes showing nearly identical waveforms in the Tonga slab. Relocation with a cross-correlation method shows that each cluster is composed of 10 to 30 earthquakes along a plane 10 to 30 kilometers in length. Some of the earthquakes are colocated, demonstrating repeated rupture of the same fault, and one pair of events shows identical rupture complex...
