U.S. fears overdue 'megathrust' earthquake will trigger tsunami and decimate unprepared cities on north-west coastCascadia fault line has lain dormant for 300 years
Eruption could trigger tsunami, devastating seaside communities - and reach as far as Japan
The
north-west coast of the U.S. could be devastated by a huge movement of
undersea plates known as a 'megathrust' earthquake, scientists say.
A
review of the dangers posed by the Juan de Fuca plate released in the
wake of the Japanese quake has raised fears that the Pacific seaboard
could be similarly ravaged.
The horrifying possibilities have been
brought to light by data researched by the Active Tectonics and Seafloor
Mapping Laboratory at Oregon State University.
