Damage is worse than any storm in memory. Since it's my former hometown,
it is especially interesting.

Local sources do not indicate any seismic activity but there may simply be
a lag in reporting. A similar but smaller surge was reported in Cundys
Harbor. Both places are similar in having configurations that could
magnify surge effects and also in that both are more active at this time
of year than other nearby areas where surge might simply not have been
observed.

The Coast Guard says surge from a storm at sea but I give that no
creedance. The effects would be over a much larger area or these events
would be more common. My guess would be a large but slow underwater slide
of bottom sediments that didn't create much seismic vibration but sucked
the water down. It's still early though and more widespread damage
reports may come in. The geologists may also look back and find an event
they would have overlooked if not for the land reports.

Add another to my long list of reasons to prefer being anchored out than
tied to a dock.


What, anchored in the same stuff that's sliding?

It's got tsunami written all over it. There IS a history:

http://www.state.me.us/doc/nrimc/mgs...nami/jan05.htm

If it happened on 10/28/08 at 3PM mentioned in the article, I don't see
any USGS Atlantic activity near that date/time or hours before, in the
Atlantic, other than several strength 2-4 quakes in a cluster along the
S side of the trench N or Puerto Rico where the 5.5 quake happened
today.

There was a 5.5 underwater quake on the south side of the trench, in a
cluster of quakes over the last day or so just N of Puerto Rico, but the
times are all wrong.

NWS report is more accurate:
"PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE GRAY ME
630 PM EST WED OCT 29 2008


....TUESDAY'S UNUSUAL TIDE FLUCTUATIONS ALONG THE MID-MAINE
COAST...

THE CAUSE OF YESTERDAY'S UNUSUAL TIDE FLUCTUATIONS ALONG THE
MID COAST OF MAINE REMAINS A MYSTERY...AND MAY NEVER BE KNOWN.
SIGNIFICANT RAPID RISES AND FALLS IN TIDE LEVELS WERE OBSERVED
AROUND 3 PM IN BOOTHBAY HARBOR, SOUTHPORT, AND BRISTOL. ONLY
VERY MINOR FLUCTUATIONS WERE NOTED AT TIDE GAUGES ALONG THE
COAST.

THERE ARE SEVERAL POSSIBLE EXPLANATIONS FOR YESTERDAY'S EVENT.
RAPID SURGES CAN BE CAUSED BY THE UNDERWATER MOVEMENT OF LAND,
MOST OFTEN DUE TO AN EARTHQUAKE, OR DUE TO THE SLUMPING OF
SEDIMENTS ALONG A STEEP CANYON OR SHELF. NO EARTHQUAKES WERE
REPORTED IN THE AREA YESTERDAY. IN RARE INSTANCES, LARGE AND
RAPID SURGES CAN BE GENERATED BY STORMS. IN EITHER CASE, THE
BATHYMETRY OF THE OCEAN FLOOR REFLECTS AND REFRACTS THE WAVE
ENERGY AND CAN CAUSES SIGNIFICANT VARIATIONS IN TIDE LEVELS
ALONG THE COAST...AND RAPID CHANGES IN TIDE LEVELS AT A
PARTICULAR LOCATION. THESE SURGES ARE QUITE UNLIKE THE MUCH
SLOWER SURGES NORMALLY ASSOCIATED WITH COASTAL STORMS.

EYE-WITNESS REPORTS FROM SEVERAL LOCATIONS INDICATED THAT WATER
LEVELS FELL AND ROSE FROM 4 FEET TO AS MUCH AS 12 FEET ALONG
THE COAST DURING THE EVENT. THESE RAPID CHANGES IN TIDAL
LEVELS GENERATED THE STRONG CURRENTS THAT DAMAGED PIERS AND
BOATS IN THE AREA.

ALTHOUGH THESE EVENTS ARE RARE ALONG THE MAINE COAST, THEY HAVE
OCCURRED IN THE PAST. ON JANUARY 9, 1926, AN EVENT SIMILAR TO
YESTERDAY'S EVENT WAS OBSERVED IN BASS HARBOR. DURING THAT
EVENT, THE HARBOR DRAINED RAPIDLY AND THEN WAS FOLLOWED BY A 10
FT SURGE OF WATER, FOLLOWED BY TWO OTHER SMALLER WAVES. THERE
WERE NO EARTHQUAKES REPORTED ON THAT DAY. NO ONE WAS INJURED
IN THAT EVENT BUT ABOUT 50 FISHING BOATS WERE HURLED ASHORE.

we envision......

Actually its more like off the continental shelf, down the continental
slope and into the abyss. Few anchor two hundred miles out. Drill rigs
maybe. These are landslides we are discussing. You might have trouble
getting an anchor to set on a steep hillside. I never tried it,
myself.

On Lake Moultrie, a friend lost his anchor to a building, or maybe a fence,
this year. He was anchored out fishing in the lake and happened to be
right over one of the submerged towns I love to scan on sonar to see if I
can find the church steeples. Only thing we can figure is he hooked
something connected to the ground like a fence anchored with fence posts or
a house, barn, something too big to lift.

He kept hauling on the anchor line until the gunwale almost went under but
to no avail. He gave up and cut the line.

If you find an anchor hooked to the front porch, I know who it belongs
to...(c;]

I wonder if the limited area of the reported occurance indicates a
close proximity of the initiating event.

Yes, it was a undoubtedly a large nuclear submarine doing war games off
shore and surfacing at a steep angle. They practically breach like a huge
whale. They can make the exact wave train experienced in the harbor but
probably enlarged in height by the shape of it.
