The Morgan Hill, California, earthquake of April 24, 1984

The
Morgan
Hill
earthquake,
a
moderate-size
(M_g=6.1,
ML
=6.2,
M=6.2)
event,
was
felt
throughout
central
California
on
April
24,
1984.
The
epicenter
of
the
earthquake
was
located
near
Halls
Valley
southwest
of
Mount
Hamilton,
and
the
event
is
presumed
to
have
occurred
on
the
Calaveras
fault.
Damage,
however,
was
concentrated
near
the
south
end
of
the
Anderson
Reservoir
and
in
the
town
of
Morgan
Hill.
A
preliminary
assessment
by
the
California
Office
of
Emergency
Services
estimated
damage
to
private
property
at
$7.0
million
and
to
local-government
facilities
at
$0.5
million,
for
a
total
of
$7.5
million
in
damage.
