in California
has been rising
in October 2019.
A batch of small
earthquakes hit
San Francisco in
mid-October.
Overall, there were
over 1,400 earthquakes
in California and Nevada
over a seven day period.
That's not unusual
for the region.
The biggest of the
batch was the
most interesting --
it was a magnitude 4.5
earthquake, felt in
the San Francisco Bay
area, at 10:33 p.m.,
on a Monday,
with the epicenter
in the Walnut Creek
and Pleasant Hill areas.
Three foreshocks
preceded the quake
( the largest was a 2.5 )
and 26 aftershocks followed,
according to Keith Knudsen,
deputy director of the USGS
Earthquake Science Center
in Menlo Park.
The USGS said there was
only a 2% chance of one
or more aftershocks
larger than magnitude 4.5
over the next week.
So, of course,
a short time later the
San Francisco Bay Area
was hit by a magnitude
4.7 earthquake, shaking
the ground in Salinas
around 12:42 p.m.
on the Tuesday after
the Monday 4.5 quake.
USGS forecasts
have not been good.
Dr. Lucy Jones,
a southern California
seismologist, insisted
Tuesday’s quake
was not connected
to Monday’s quake !
That sounds
like BS, to me
because,
as is very common
in real science,
the behavior of
earthquakes remains
a great mystery
for our top scientists.
So when “experts” tell us
huge quakes, like the one
that hit San Francisco
in 1906 happen :
“about every 200 years”,
they are just guessing !
The California earthquake
of April 18, 1906 ranks as
one of the most significant
earthquakes of all time.
According to the USGS,
a magnitude 9.0 earthquake
would release 2,818,382
as much energy as the
magnitude 4.7 earthquake
that happened recently.
The California coastline
sits directly along the
earthquake “Ring of Fire”.
“The Big One” will hit
the state someday
-- perhaps a repeat
of the famous 1906
San Francisco
earthquake ?
Southern California
is more vulnerable,
but northern California
is vulnerable too.
