Re: For Mark. Deep Earthquakes, Maybe One Answer

Hi Mark. Here is another deep earthquake you may find interesting. Some good information was obtained from this quake, but unfortunately most of it doesn’t apply to the Bolivia quake. Take Care…Don in creepy town.

One of the largest (Mw=7.9) deep earthquakes (595 km) in recorded history occurred beneath the Flores Sea on June 17, 1996 (Fig. 1). The mechanism for this event indicates both normal and strike-slip motion along a moderately dipping, southeast striking fault plane (Jiao et al., 1997) (Fig. 1). Unlike the deep Bolivian earthquake (Mw=8.3) of 1994, the Flores event occurred along a seismically active portion of the deep Australia-India (A-I) slab (Fig. 2). It produced at least 16 aftershocks (mb > 2.9) during the first 18 hours after the mainshock. The aftershock hypocenters span a lateral distance of approximately 85 km along the strike of the slab and 76 km antithetic to the dip of the slab. This energetic aftershock sequence, and the large area of main shock fault slip inferred from the aftershock distribution, are unusual of deep earthquakes
