a bright and sunny day in January 1607 an 18ft wall of water burst
onto the Somerset coast swamped ground as far inland
as Glastonbury Tor (14 miles from the coast).
the early years of this millennium, geoscientists have thought that
the tsunami was caused by an earthquake (and possibly an associated
earth slip on the seabed) out in the Irish Sea.
tsunami was funnelled up the Bristol Channel (in the same way that
the Severn Bore is) and drowned 2000 people in Somerset, North Devon
and South Wales. In Wales large boulders - that could only have
been moved by tsunami sized waves - are still to be found stacked
up like dominoes above the high tide limit.
an event could never happen again? Probably not but there was an
earthquake (4.1 magnitude) under the Bristol Channel this February.
scientists are keen to install an early warning system to warn of
tsunami in the Irish Sea but the government don’t want to
