What Will It Take To Get Our Attention? Three
earthquakes in three days. More than coincidence?
First came an earthquake in Colorado. Then Virginia's quake shook
the US from South Carolina to New England. Finally, San Francisco
had a rattler as well. Are they connected?

Colorado, Virginia, California: three earthquakes across the United
States in three days. Aside from the apocalyptic questions some are
raising, was this more than an earth-trembling coincidence? Or was
there some scientific connection between these three events?
First there was the magnitude 5.3 earthquake near Trinidad, Colo.,
the largest earthquake in the state since 1973. Then a magnitude 5.8
quake centered in Mineral, Va., jarred a region from Charleston,
S.C. to Boston. Finally, there was a relatively mild 3.6 rattler in
the San Francisco area Tuesday night.
What’s going on here?
Experts say that while the Colorado and East Coast earthquakes were
unusual, the first one did not trigger the second. Nor did the San
Francisco quake have anything to do with the two that preceded it.
“They really are unrelated,” says Meredith Nettles, a seismologist
at Columbia University. “There really is no causal connection.”
“This is pure coincidence,” concurs San Diego State University
seismologist Tom Rockwell.
“That’s because small earthquakes don’t change the state of stress
very much in the crust of the earth, so the effects will be only
local,” he says.
While this week’s earthquakes made news – with earthquake tremors
and hurricane Irene on the way, some people in North Carolina
wondered if a plague of locusts was next – the earth’s
shake-rattle-and-roll is going on all around us almost constantly.
In just the past week in the US alone, there were about 700
earthquakes perceptible to detection equipment. And as the US
Geological Survey puts it, “there's a 100 percent chance of an
earthquake today” somewhere in the world.
More than 700 earthquakes a year around the world “may be
sufficiently strong to cause property damage, death, and injury,”
according to the USGS, “but fortunately, most of these potentially
destructive earthquakes center in unpopulated areas far from
civilization.”
One of the largest recent earthquakes (magnitude 6.8) occurred July
31 near the north coast of Papua New Guinea. (Because they’re
figured logarithmically, a 6.8 quake has ten times the amplitude of
a 5.8 one.)
[UPDATE: A magnitude 7.0 earthquake hit a remote area of Peru near
the border with Brazil Wednesday. There were no reports of damage or
injuries, according to the Associated Press.]
Though aftershocks can be expected to occur, even larger earthquakes
are unlikely to trigger major events elsewhere, according to a
report in the journal Nature Geoscience last year.
“Based on the evidence we’ve seen in our research, we don't think
that large, global earthquake clusters are anything more than
coincidence,” said Tom Parsons, USGS geophysicist and author of the
study.
Earthquakes in the central and eastern United States, although less
frequent than in the West, typically are felt over a much broader
region.
“East of the Rockies, an earthquake can be felt over an area as much
as 10 times larger than a similar magnitude earthquake on the West
Coast,” according to the USGS. “A magnitude 5.5 eastern US
earthquake usually can be felt as far as 300 miles from where it
occurred, and sometimes causes damage as far away as 25 miles.”
As San Diego State University's Dr. Rockwell explains it, that’s
because of the difference in earth’s crust on the two US coasts: the
West is mushier and more broken up, the East is old granite.
Using a sound metaphor, Rockwell likens the West’s crust to a block
of wood, the East to a brass bell with the sound of the bell heard
much farther away.
“Seismic energy gets transmitted farther and stronger with
high-quality rock,” he says.
Related to this, Columbia University's Dr. Nettles notes that it
probably was a good thing that the Virginia quake was located
between populated areas. “If you’re going to have an earthquake of
this size on the East Coast, that was a pretty good place to have
it.”

(Washington, D.C, August 23, 2011) -- Three rare earthquakes have
hit the U.S. in two days -- a 5.9 magnitude tremor epicentered in
southern Virginia on Tuesday shook the White House, Capitol and
Pentagon and was felt up and down the Eastern seaboard; and the
largest earthquake in Colorado and New Mexico four decades occurred
on Monday. Finally, there was a relatively mild 3.6 rattler in the
San Francisco area Tuesday night. Until now, I'd never experienced
an earthquake before. While the one here in the D.C. area was
relatively mild (compared to the one in Japan, for example), it made
me think of the column I wrote last month, entitled, "The Lord is
shaking the nations physically, spiritually, financially: Why, and
how should we respond?" A few excerpts might be worth reconsidering
today:
* "Americans, too, are being shaken. We face arguably the worst
economic crisis since the Great Depression. Nearly half of all
Americans believe we are heading towards another Great Depression.
Unemployment is over 9%. Housing foreclosures are skyhigh.. People
have lost enormous sums of money due to depressed housing prices and
stock market volatility. The federal government is trying to spend
our way to prosperity but is making things worse. Our annual federal
budget deficit topped $1.3 trillion last year. This year, it looks
like the feds will spend more than $1.5 trillion beyond what they
are taking in in revenue. Our debt is skyrocketing. The U.S. is now
on the verge of financial default, and hampered further by political
ineptitude in Washington that threatens to comp0und an already
precarious situation."
* "What if these events are not all random? What if the God of the
Bible is allowing these to happen to shake us, to wake us, to get
our attention, that we might turn to Him and ask Him to have mercy
on us and help us?"
* "The Lord said through the ancient Hebrew Prophet Haggai that the
nations would be shaken in the future. "For thus says the Lord of
hosts, 'Once more in a little while, I am going to shake the heavens
and the earth, the sea also and the dry land. I will shake all the
nations….I am going to shake the heavens and the earth. I will
overthrow the thrones of kingdoms and destroy the power of the
kingdoms of the nations." (Haggai 2:6, 7, 21, 22)
Now would be a good time to rededicate ourselves to praying and
fasting for America and Israel at this critical time and turning our
hearts to spending more time in the Scriptures.
