that
is

on
an

the

In
East
Africa
such
seismic

can
wreak
Damaging
havoc
.
It
was
one
of
the

The

was
equipped
Supply
with
an
array

for
analyzing
the
fault
mechanisms
of
nearby
earthquakes
Catastrophe
and
seismic
characteristics
of
the
sediments
in
the
valley
.
The
Loma
Prieta
segment
of
the
San
Andreas
Fault
System
had
been
relatively
inactive
since
the
1906
San
Francisco
earthquake
Catastrophe
(
to
the
degree
that
it
was
designated
Coming_to_be
a
seismic
gap
)
until
two
moderate
foreshocks
Attack
occurred
Coming_to_be
in
June
1988
and
again
in
August
1989
.
The
record
of
previous
seismic
activity
includes
major
earthquakes
Catastrophe
in
1647
,
1730
and
1822
.
although
the
2011
earthquake
Catastrophe
was
the
largest
on
record
,
the
usgs
reported
Reporting
that
the
central
and

u.s.
(
ceus

has
undergone

the
most
dramatic
increase
Cause_change_of_position_on_a_scale
in
seismic

activity
in
the
united
states
since
2009
with
an

of
318
earthquakes

up
from

from
1973
to
2008

The

However
,
the
figure
of

is
based
on
a
historical
conflation
of
this
earthquake
Catastrophe
with
earthquakes

in
November
1137
on
the
Jazira
plain
and
the
