Digging into the soil at the Effingham Inlet in British Columbia,
Canadian scientists have confirmed that a city-destroying megathrust
earthquake in the Northwest is due.
The Cascadia Subduction Zone running the length of
the coast from northern Vancouver Island down to California last slipped
and shook the surface of the Earth 300 years ago, and that was just the
latest of 22 such quakes in the past 11,000 years.
The scientists, whose work is published in the
latest Canadian Journal of Earth Sciences, used a new aging model for
identifying and dating disturbed sedimentary layers in a core raised
from the inlet.
The disturbances appear to have been caused by large
and megathrust earthquakes that have occurred over the past 11,000
years, According to a science news site run by the American Association for the Advancement of Science. READ MORE
