Factors controlling damage and fatality rate from an. Earthquake-related factors: size of eq distance to eq depth of eq type of eq location of eq (ocean, land, type of plate boundary) Geology and human factors: local geology sedimentary basins enhance shaking (site amplification) area with certain geology (e. g. sedimentary cover) prone to liquefaction (see below) Earthquake) population density time of day controls number of fatalities bad times in areas with poorly build residential housing: night times when most people are at home (e. g. 2003. When water depth is greater than 1/2 wavelength l. wave speed depends on wavelength: v=l/t, where t is the wave period. It turns out that if t is known, v can be obtained through v=g x. T/(2 ), where g is the gravitational acceleration (9. 81 m/s2) shallow-water waves: waves sense the bottom. 515mph) due to low dissipation (slow decay in wave amplitude), can cross large ocean basins using the formula: tsunami take about 6. 5h from alaska.
