VERY STRONG GEOMAGNETIC STORM ACCOMPANIED BY INCREASE SEISMICTY
SEISMCITY PEAK IN THE EASTERN U.S./CANADA ASSOCIATED WITH HURRICAN MICHELLE

SUMMARY

GEOMAGNETIC STORM

The CME from yesterday's X1.0 flare arrived tonight with several
associated arrivals. The first of these began at about 20:37-20:42 UT and
was followed shortly by a moderate geomagnetic storm. This was followed
almost immediately by a Ml 2.2 in the Joshua Tree, CA region at 20:37 UT
(12:37 PST) and by a Mw 6.3 earthquake in the Fiji Islands about 1.25 hours
after that (23:07 UT). Things quieted down then for several hour and
at 01:52 UT on Nov. 6, the strong CME struck raising the Kp levels
to 9 and changing the total geomagnetic field by about 50% in less than
5 minutes. This event was well recorded by seismograms (see Geomagnetic
field section below). An earthquake of unknown magnitude was associated
with this shock wave in the Alaska Peninsula at 01:54 UT. A second shock
wave hit at 03:54 UT (19:54 PST). Simultaneously with this shock,
two earthquakes occurred in the Coalinga region of California of
Ml 2.8 and 2.4. Two more were recorded about one and two hours later
which were also associated with geomagnetic field changes.

HURRICANE MICHELLE

Hurricane Michelle, the strongest to hit Cuba in more than 50 years
(since 1944) caused extensive flooding in that nation yesterday
and today and has veered away from the state of Florida towards the
Islands of the Bahamas and Bermuda.
Coincident with Michelle were a series of unusual earthquakes in
the eastern and Central U.S. Because the path of Michelle was such
that induced motion on the North American continent was likely,
this increase in regional seismicity had been forecast here.
The strongest event was recorded by the Nicaraguan network (SIS)
and has not yet been verified. They report a Ml 5.3 earthquake in
an unusual location south of Cuba this afternoon. It is not known
whether this is an effect from the hurricane or a triggered
earthquake.
For Nicaragua network earthquake list see:
http://www.ineter.gob.ni/geofisica/sis/events/ca.txt

In the U.S. the first earthquake recorded in North Carolina since
September 28 occurred near Bryson City with Ml 1.6. Other earthquakes
have occurred in North Carolina this year on July 7-10 (Ml 2.1, 2.3);
May 21 (Ml 1.9); and Jan. 20 (Ml 2.1). One earthquake was recorded
in North Carolina during the year 2000. For seismic events in the
eastern U.S. see:
ftp://tanasi.gg.utk.edu/dist/JIEE/Events/00readme.txt
As Michelle hit Cuba a Ml 2.0 was also being recorded in the New
Madrid fault zone. This area often shows hurricane-associated seismicity.
In southeastern Canada, a Ml 2.0 was registered near La Baie, Quebec.
The most unusual event, which might have been a reaction to plate
motion associated with Michelle landfall occurred in the Colorado
Rocky Mountains this morning of Ml 3.5 near Aspen, Colorado. This is
an extremely rare event. Catalogs indicate only three events of Ml>=3
have occurred within 50 km of this epicenter since the late 1800's.
The first of these was a Ml 5.0 on Sept 9, 1944. This earthquake also occurred
at the time of landfall of a hurricane - that one on Sept. 9 hit
in the Baton Rouge LA area and was, like Michelle, moving in a N-S
direction. The second (Ml 4.4) occurred on Jan 12, 1967 and was not associated
with a hurricane landfall. The last such event occurred after
landfall of Hurricane Charley which hit in a N-S direction on
the Panhandle of Florida. The earthquake occurred on Sept. 3, 1986 (Ml 3.5).

GLOBAL

Strong activity continued today in the mid-Ocean ridge systems of the
world. NEIS is reporting earthquake near ocean ridges in the past 2 days
in the South Indian Ocean (MB 4.1); Easter Island (SE Pacific (Mb 4.6);
Southeast of Easter Island on the East Pacific Rise (Mb 5.0); and in the
South Sandwich Islands (MB 5.0).
The strongest earthquakes of the day were a Mw 6.3 in the Fiji Islands
area which occurred shortly after the geomagnetic storm struck and an
Mw 6.0 near the Coast of Central Chile which also occurred shortly
after a strong solar wind burst.
Other earthquakes of Mb>=5 since last report occurred in the Crete,
Mediterranea Sea area (Mb 5.0); Taiwan (Mb 5.1); and Sulawesi (Mb 5.2).
Earthquakes of Mb>=4 have been recorded in the Banda Sea (Mb 4.2); the Near
Islands, Aleutians (Mb 4.4); and Sakhalin Island (Mb 4.6).

U.S./CANADA

The largest earthquake recorded in the U.S./Canada area was the
Mb 4.4 in the Near Islands, Aleutians. An event of Ml 3.6 was also
recorded in southern Alaska.
In the U.S. volcanic areas were very active today. This may be
the result of Ohmic heating as described in yesterday's report.
In addition to the strong swarm under Mt. St. Helen's, WA (see yesterday's
report) and Mammoth Lakes, CA, a strong earthquake swarm is also occurring
in Yellowstone Park, where the largest earthquakes in the contiguous U.S.
occurred in the past 24 hours of Ml 3.0 and 3.0. This size event in the
Yellowstone region occurs about every 6 months. For details on this
swarm see:

http://www.quake.utah.edu/req2webdir/recenteqs/Quakes/quakes0.html

Hawaii also recorded the largest events in that region since the
Loi'hi swarm of early September, 2001. Earthquakes of Ml 3.8 and 3.6
were recorded in that area today. Hawaii had been an area where
high seismicity was expected at this time as FFA from several events.
For a listing of Hawaii earthquakes see:

http://elsei.wr.usgs.gov/results/seismic/recenteqs/Quakes/quakes0.html


Other volcanic areas of the U.S. showing seismicity were Mt. Rainier,
WA. and the region south of Vancouver Island where a swarm occurred
in early September. The largest event since that swarm occurred in that
region this morning with Ml 3.8. For listing of Vancouver Island
earthquakes see:

http://www.pgc.nrcan.gc.ca/seismo/recent/wc.50evt.list.html

In other seismicity of the U.S./Canada region, the strongest
events in the California/Nevada area were associated with a swarm
of events in the area SE of Coalinga, CA. These events appear to
be associated with the current geomagnetic storm, as they have
all occurred at times of strong geomagnetic changes and gusts of
solar wind striking the earth. The Coalinga events occurred
as Ml 2.1 (06:36 UT, strong total geomagnetic field decline began
at 06:36); Ml 2.0 (05:45 UT, strong total geomagnetic field decline
began at about 05:43-05:45); Ml 2.7 (04:38 UT strong geomagnetic
enhancement began at 04:34); and Ml 2.4 and 2.8 (03:54 UT, strong
geomagnetic field decline began at 03:54). Anza aftershocks also
appear to be related to field changes, but not as obviously.
From the last report to this, the seismicity of California
had been strongly quiet with only one minor events of Ml 2.0 or
greater in more than 24 hours. This had occurred at Coso Junction
and was Ml 2.0.
Seismicity in the rest of the U.S. and Canada today has been
described in other sections, including references to the most
unusual events in north-central Colorado (Ml 3.5); the swarms
at Mt. St. Helens, Mammoth Lakes, Hawaii and Yellowstone N.P
and the several events in southeastern Canada. In addition several
earthquakes have occurred in southern Canada near the Minnesota
border in the past three days. These may be related to FFA of the
New Britain earthquake of 31 October as the great Plains was an
area where FFA were expected. This area had seen only two events
in the catalog through 1999, but a swarm of microearthquakes in the
area on Aug. 12, 2000 has been followed by four shocks in the Ml 1.0-2.1
range since, the last being on April 27, 2001.

NEW ZEALAND

IGNS reported only one event today, a Ml 3.7 on South Island
near Seddon. NEIS, however reported two additional events in
the region since our last report. These occurred in the Kermadec
Islands (Mb 4.2) and in the aftershock zone off the North Coast of
North Island (Mb 4.9).
The on-line seismogram has been relatively quiet today with
only a few regional events. The long event is the Fiji Islands (Mw 6.3).

GEOMAGNETIC/SOLAR FIELDS

For the doubters among you who still do not believe that there is
considerable disturbance on seismometers associated with strong
CME, I would suggest your take a gander at the seismograms tonight
for the two strong CME's that arrived in the past 3 hours. The
Kp index is now 9 - as high as it will go. For graphics, forecast
and general information see:
http://sec.noaa.gov/today.html

For specific data on exact timing of CME collisions see:

http://sec.noaa.gov/ftpdir/lists/geomag/20011106_G8mag_1m.txt

The two CMEs arrived at 01:52-01:53 UT tonight (05:52 PM PST)
and 03:54 UT (7:57 PM PST)

The collison was well recorded on a number of seismograms. Jen of
New Zealand has already noted the disturbance on the Karori and
Cannon Point seismograms in New Zealand, but here are others
to check:

At 01:53 the change in the total field was about 50%. Seismograms
recorded this event as follows:

SEC has noted that the LASCO imaging system has been severely
degraded by the extreme proton storm currently in progress. It
is therefore not possible to know if additional CME have occurred
on the sun, and if the earth is going to be subject to more
events such as tonight's in the next several days. One of the
consequences of such storms is the degradation of satellites
and satellite communication, and this is an excellent example.
The proton storm continued at very high levels and electron
flux was virtually non-existent throughout the day. However both
sudden commencement storms were associated with seismicity - the
first with the Mw 6.3 in the Fiji Islands at 23 UT and the second
with the beginning of this evening's swarm near Coalinga California.
In addition to the strong geomagnetic storms and CME effects,
the following minor M-class flares were observed to occur on the sun.


Flare # START MAX END CLASS

820 + 0247 0250 0253 M1.7

TROPICAL STORMS

HURRICANE MICHELLE

Hurricane Michelle, the strongest to hit Cuba in more than 50 years
(since 1944) caused extensive flooding in that nation yesterday
and today and has veered away from the state of Florida towards the
Islands of the Bahamas and Bermuda. Michelle rapidly lost energy
in it's encounter with Cuba and has reduced to a Category 1 hurricane
moving into the central Atlantic Ocean. There may be residual
seismicity in the east coast of North America or along the northern
subduction zone of the Caribbean, however the main effects on
seismicity from Michelle are now believed to have occurred.

For tracking details see:

http://www.wunderground.com/auto/HurricaneSite/tropical/tracking/at200115.html

TROPICAL STORM NOEL

Tropical Storm Noel is forming in the north Atlantic Ocean. Noel
reduced quickly from a Category 1 Hurricane and is rapidly moving
to the north. It is expected to make landfall off Newfoundland tomorrow.
Little associated seismicity is expected. For tracking details see:

TIDAL TRIGGERING (LUNAR)

Statistics have been done on many regions of the world in terms of
relationship of significant regional earthquakes with respect to lunar cycle.
Each report will summarize the most likely areas for tidal triggering
for the next day based on these statistics. It is expected
that tidal triggering will add an additional 0.5 - 1.0 units of
magnitude to events which are about to occur or will move these
events forward in time by up to seven days in the regions where
there is a statistical correlation between lunar phase and
earthquakes.

November 6 is twenty-one days after the beginning the lunar month
Regions most likely to experience tidal triggering
on this day (With associated magnitude ranges; the percent change in
seismicity rate over background seismicity rate on this
day of the lunar month; statistical z-value and
significance level) are:

Region Magnitude range %change z-value Significance level

Central California MB>=0.0 37 2.4 0.04
Central California MB>=3.0 18 2.2 0.05
