The damage is usually not covered by your homeowners insurance policy. Some of the water travels out and across the ocean basin, and at the same time, water rushes landward to flood the recently lowered shoreline. Additionally, rising sea level has accelerated coastal erosion, which has resulted in wetland mi - gration and cliff collapse. Hawaii conjures up images of gently swaying palms, shimmering turquoise waters, and footprint-free, sugary-white sand beaches, and it doesn’t disappoint. The new area will step away from tsunamis and focus on hurricanes, flooding, earthquakes and volcanic activity, which can all be experienced on Hawaii Island. In our video Earthquakes for kids we will provide and simple and engaging introduction to both earthquakes and Tsunamis.

If caught by a tsunami wave, it is better not to swim, but rather to grab a floating object and allow the current to carry you. Unlike ocean-wide tsunamis caused by some earthquakes, tsunamis generated by non-seismic mechanisms usually dissipate quickly and rarely affect coastlines far from the source area. Giant landslides and collapses of ocean island volcanoes were first described in 1964 in Hawaii and are now known to happen in almost every ocean basin. These push the water upward, sideways or downward to create the tsunami waves. Geologic hazards cause billions of dollars in property damage and kill thousands of people every year.
