Buildings fell and entire towns were washed away by the tsunami that followed in the aftermath of the powerful earthquake. However‚ considering the sheer magnitude of the earthquake‚ Alaska suffered minimal damage to its residents and economy for a number of reasons. On the contrary‚ the Alaskan economy temporarily prospered from the ’64 earthquake by receiving additional

tectonic plates which are constantly in motion due to the convection currents caused by heat cycles in the mantle‚ driven by radioactive decay in the Earth’s core. Natural hazards caused by plate tectonics are earthquakes‚ volcanic eruptions (and tsunamis – secondary effect of the first two). It is important to understand that there is a clear division between a natural hazard and a natural disaster. A good example would be the 1906 San Francisco earthquake which killed about 3000 people and was a

Earthquakes are caused when the tectonic plates (giant slabs of rock) grind together causing the build up of huge forces. When the pressure gets too much‚ the edges of the plate suddenly

trigged a tsunami‚ with waves reaching 3m in height that destroyed several buildings and killed 3 people (Dell’Amore et al.‚ 2010). The tsunami was unexpected due to the type of earthquake that had occurred. The earthquake was a strike slip earthquake which means the plates slipped horizontally against one another‚ which normally wouldn’t cause a tsunami due to there being no vertical movement of the plates‚ which is needed to create tsunamis. A current theory for the cause of the tsunami is multiple
