With the extent the region has built up in infrastructure as well as population, any repeat of the 1906 San Francisco quake would result in absolute chaos.

Time - slices from the Ward & Day ( 2001 ) Cumbre Vieja tsunami model , showing the location ... [19] By contrast, given a slide density value (i.e., 2,500 kg/m3), Figure 7 (right) shows that a variation in the slide center of mass vertical position ZG has a major influence on maximum free surface elevation; this could have been expected since the initial slide potential energy is proportional to ZG. 4. Small Bodies, Solar Systems Using a geologically reasonable estimate of landslide motion, we model tsunami waves produced by such a collapse. If it ever occurred, i knew what the escape route was and where highest ground in area. Hence, at every time step the volume fraction of each constituent is known in each grid cell. More than 250 sizable quakes were detected during the past 24 hours, and more than 3000 in total have been logged over the past 4 days, reports volcanodiscovery.com. The path of each wave is sketched on Figure 16 (left) and the maximum amplitudes reached by the leading waves in each train are plotted in Figure 16 (right). Additionally, the Navier-Stokes model used is different (incompressible). The slide center of mass is located 500 m above sea level, 2.5 km West, and 12 km North of La Palma's southern cape. after the 1755 Lisbon earthquake. For instance, with Δzmin = 10 m, one would expect results' accuracy to be at best about 2 or 3 times this value (i.e., 20–30 m) assuming 3 grid cells are required to resolve a wave. Answer (1 of 3): Oceanic oceanic stratovolcanos similar to Cumbre Vieja do collapse catastrophically from time to time, the median rate of occurrence being every few tens of thousands of years, world wide. That is FACT. This is mainly due to the fact that, after generation, waves and landslide do not follow the same trajectories and, especially in 3D, the wavefield spatial extent rapidly grows with time. Figure 10a shows slide tip location (i.e., distance to shore) calculated in the vertical plane in the approximate direction of the maximum wave energy. [72] The slide has a complex acceleration behaviour and most of the waves are formed during a short period early in the slide where the Froude number briefly exceeds 1;[73] the initial wave can reach a height of 1.3 kilometres (0.81 mi)–0.8 kilometres (0.50 mi)[74] and eventually wave trains are formed, which are diffracted around the southern tip of La Palma and go on to hit the other Canary Islands. Figure 13 shows that at t = 450 s, three main leading waves have been generated in all cases. The asymptotic value reached in this calculation represents 30–40% of the slide energy loss at this time. [2008]with a qualitatively similar wave showed that a non-dispersive model would overpredict the tsunami amplitude in comparison with a BM, and produce steeper waves that would break earlier.
