We swam with our children in the small coves near a series of large rocks in San Agustinillo, starting shallow then slowly moving out a little deeper.
You'd expect to see a risk curve that starts shallow at T-Bills (which are as close to riskless as can be), that then curves dramatically upwards to junk bonds (which offer more reward to compensate for the riskiness of the bet).
Moreover, crustal dehydration starts shallower for fast slabs and ends deeper, resulting in a much wider area, or a larger pressure range, where water is released from the slab into the mantle wedge.
We find that the main factor that influences the onset and the area of slab dehydration is the subduction velocity: dehydration of fast slabs starts shallower, but ends deeper than for slow slabs.
With a hotter mantle, and keeping the other parameters fixed, the crustal dehydration starts shallower, and involves amphibole instead of talc, but similar results can be obtained by varying the subduction velocity.
Started off shallow and mean, slowly gained psychic depth through association with Buffy and her friends.
Most of the failures in the field started as shallow translational slides at terrain slopes between 25° and 45° and involved volumes of some tens to a few hundred cubic meters.
Interestingly, the high-frequency activity started from shallow (< 1 km below sea level) and gradually propagated deeper (5 km below sea level) in the first approximately 24 h (Fig. 16).
Thus, the eruption sequence started with shallow crack formation and uplifting of the vent area and was then followed by propagation of high-frequency earthquakes to more than 5 km below sea level taking more than 24 h.
