HURRICANE OLGA TAKES NEW PATH; CHIAPAS MB 6.3 EARTHQUAKE WAS EXPECTED

SUMMARY

HURRICANE OLGA MOVES TO A DIFFERENT DRUMMER

Keep an eye on Hurricane Olga - if she hits North America or the
Caribbean from the northeast, we could be in for some very interesting
seismicity. See Tropical Storms section below for more details and
speculation.

CHIAPAS MB 6.3

A Mb 6.3 earthquake occurred in the Chiapas, Mexico at 93W longitude this
morning. This event was anticipated in these daily reports. Four days
ago on November 24, a strong geomagnetic storm occurred, commencing
at 5:45-6:15 UT while the region near 90W longitude was sub-solar.
The report stated at the time:

"A severe (Kp>=9) geomagnetic storm arrived this morning at
about 05:45 UT. This was a suden commencement storm and severely
degraded to readability of most of the on-line seismograms.
Areas which are sub-solar include regions within 20 degrees longitude
of 90E; anti-solar areas are within 20 degrees longitude of
90W, however the strength of the storm suggests that 30-35 degrees
should be taken about the anti- and sub-solar longitudes to be
included in the seismic watch.
The seismic watch will include regions between 125W and 55W and
between 125E and 55E and will extend for the next 5 days. The
largest events are most likely to occur 4-6 days following the
storm"

This watch was repeated in the November 26 report which stated:

"The most likely strong seismicity from the geomagnetic storm on 24 November
is expected to occur between 28 Nov. and 1 Dec., 2001. "

And on November 25:

"The geomagnetic field returned to quiet conditions today after
yesterday's geomagnetic storm. The storm is expected to trigger
several earthquakes in the Mw>=6 range between November 28 and
December 1."

and

" Global and regional seismicity remained relatively quiet through
the past 24 hours. As the proton storm wanes and dissipates by
tomorrow, and with the arrival of a subsequent CME from today's
X1.1 solar flare, these quiet conditions could change to active
seismicity. The largest events appear most likely to occur between
Nov. 28 - Dec. 1, 2001, if they are triggered by the geomagnetic
storms and the two X1.1 flares."

The other active area continued to be Nepal which lies near the
sub-solar point at 82E. Four moderate earthquakes have occurred
in this region in the past two days.

GLOBAL

In addition to the Nepalese and Chiapas earthquakes other events
of Mb>=4.5 occurred today in the Minahassa Peninsula south of the
Philippines Islands (Mb 4.7); in the Gulf of California (Mb 4.3);
east of North Island, New Zealand (Ml 4.6); in a continuing sequences
south of the Kermadec Islands, New Zealand (Mb 4.8); in the Fiji Islands
(Mb 5.0, 4.7) and in the South Sandwich Islands (Mb 4.7, 4.5). Most
of these events were at distance and region where FFA from the Kunlun
Mts. great quake had been expected to occur.

U.S./CANADA

The U.S and Canada showed signs of renewed seismic activity today
after nearly a week of very low seismicity. The largest earthquake
in the general region was a Mb 4.2 in the Gulf of California. This
area of the Northern Gulf of California has been relatively quiet
in recent years. Since 1990, only 10 earthquake of Mb>=4 have occurred
within 100 km of today's epicenter. Three of these were immediate
aftershocks, so there have been only 8 days on which earthquakes of
this magnitude have affected this area and only four of these -
on Jan 16, 2001 (Mb 4.5); August 25, 2000 (Mb 4.4); July 29, 1999 (Mb 4.4)
and August 3, 1995 (Mb 4.3) were larger than today's event. The largest
earthquake ever recorded in this region was a Mb 5.3 on August 18, 1958.
Mb 5.2's have occurred twice. The region was expected to see moderately
strong activity at this time as noted in the far-field forecast from the
New Britain earthquake of Oct 31, 2001 and repeated in the daily report
of November 25:

"Seismicity often increases in So. California about a month following
strong earthquakes in the New Britain region. The far-field aftershock
forecast of the Mw 7.0 New Britain event on October 31 had noted:

' There is a strong relationship between New Britain events and
succeeding earthquake in southern California especially in the
area of Anza to the Salton Sea. This is probably because wave
fronts from New Britain arrive approximately parallel to the
San Andreas in this region, promoting larger events. This area
should remain active for several week. A larger event in this
area often occurs 28-33 or 43-46 days after the event in New
Britain, so the danger is not yet over.'

The danger period should begin on November 28 and last through
Dec. 3, 2001."

Other regions in the California/Nevada area also became active
today after a sharp decline in regional activity in recent days.
In the north, a series of earthquakes of in the Weaverville area
occurred (Ml2.8, 2.4. 2.6) occurred. Light earthquakes in the north were
also recorded near Petrolia (Md 2.5) and in the San Ardo area west
of Parkfield (Md 2.3). The strongest earthquake outside the Gulf
of California in the region was a Ml 3.1 on the Northern San Andreas
fault near Point Arena.
The Point Arena area is NOT a highly seismic zone. Only 29 earthquakes
of Ml>=3 have ever been recorded within 40 km of today's epicenter.
In the past 13 years (since 1988) only 5 days have seen events of
Ml>=3 in this region, and only three of these were larger than
today's earthquake. The last earthquakes in this region of Ml>=3
were a Ml 3.0 on April 13, 2001; a Ml 3.3 on Feb 2, 2000 and
a Ml 3.0 on March 12, 1998. The largest in the past 13 years occurred
on Nov. 22, 1997 (Ml 3.9). The only other event of Ml>=3 in this
time period was on Jan. 2, 1993 (Ml 3.1). So this is a significant
regional event.
The Southern California area also showed renewed activity today
with three events of Ml>=2 - the first in 3 days in that region (since
a Ml 2.1 on Nov. 25 near Barstow). Today's events occurred at Simi
Valley (Ml 2.3 and 2.1) and near Coso Junction (Ml 2.1).

In the U.S. Rocky Mountain states, a moderate swarm of earthquakes
which started on Nov. 26 is continuing in the Yellowstone N.P. area.
The maximum magnitude in this swarm thus far reported has been Ml 2.5.
No earthquakes of Ml>=2 have been listed from other areas of the U.S.
today.

Canada also had some two highly unusual earthquakes north of
Yellowknife, N.W.T. this morning. These events were registered as
Ml 4.2 and 4.5. Only one other earthquake of M>=4 has ever been

recorded within 200 km of today's epicenters - a Ml 4.6 on Jan. 10,
1966 about 150 km northeast of today's events. No earthquakes have
ever been reported within 100 km of today's with Ml>=4. These events
lay within the seismic watch area from the geomagnetic storms of
November 24 and are at high latitude where effects are expected to
be most prominent.

Both Alaska and Hawaii saw one earthquake each of M>=3 (Ml 3.0 and
3.3, respectively).

NEW ZEALAND

A strong earthquake was located in the Southern Hawke's Bay area
this afternoon (Ml 4.6; IGNS). This is probably an FFA from the
Kunlun Mts. The general region has been quite active since that
great earthquake and lies on the edge of the p- and s- shadow
zones from it.
Similarly located with respect to the Kunlun Mts., the Kermadec
Islands and the Fiji Islands also saw earthquakes today (Mb 4.8; 4.7, 5.0
respectively. The Kermadec event is one in a continuing series
that started with the Ml 6.4 north of these events on 22 November.
The on-line seismogram showed 4 other light to moderate regional
events in the past 24 hours but IGNS has not yet parameterized
these earthquakes.

GEOMAGNETIC/SOLAR FIELDS

The geomagnetic field remained at very quiet conditions today. There
have been two strong M-class flares since last report, however, with
the following parameters:

Flare # START MAX END CLASS

ON November 27:
6780 + 2109 2121 2132 M2.2

ON November 28:
7140 1624 1635 1641 M6.9

No seismicity was recorded coincident with the M2.2 flare on Nov. 27
(#6780), however the strong M6.9 class flare today was accompanied by
a strong increase in X-ray flux starting about 16:20 UT and by the following
earthquake in the Gulf of California:

O: 28NOV2001 16:24:07 30.7N 113.0W MB=4.3 NEIS GULF OF CALIFORNIA

The region of the northern Gulf of California to the Salton Sea
often shows strong triggering effects from strong M- or X-class solar
flares.

TROPICAL STORMS

Hurricane Olga continued circling in the Central Atlantic Ocean
today. The hurricane forecast, however, is now expecting Olga to
take the highly unusual path to the southwest headed for northern
Cuba. In fact, this path is so unusual, only one hurricane since the
late 1800's has ever anywhere near this path - Hurricane #6 - which
hit Virginia and Florida from the Northeast on November 1-4, 1935.
For the path of Hurricane 6 in 1935 see:

http://www.nhc.noaa.gov/tracks/1935.gif

Hitting Florida from this direction tends to increase the differential
motion of North America with respect to the Pacific plate, increasing
the potential for significant activity along the boundary between
these two plates and in general adds very strange forces to the
plate, which may result in highly unusual earthquakes.
As Hurricane 6 hit on the morning of November 4, 1935, a series
of unusual earthquakes began in North America.

As Olga was approaching North America from the northeast it came near
Virginia on Nov. 1, 1935 and then took a sharp turn to the south. At Olga's
closest approach to Virginia, a strong earthquake occurred in Quebec with the
following parameters:

O: 01NOV1935 06:03:40 46.8N 79.2W Ml=6.2 GSC Temiscaming, Quebec
O: 02NOV1935 14:31:58 47.2N 78.2W Ml=5.4 SCSN Temiscaming, Quebec

This was the largest earthquake ever recorded in this region of Canada.
The aftershock about 100 km to the NE on November 2, was the second strongest
event ever recorded in this region of Canada.

http://www.wunderground.com/auto/HurricaneSite/tropical/tracking/at200117.html

TIDAL TRIGGERING (LUNAR)

Hurricane 6 hit Florida about 03:00 on Nov. 4, 1935 UT
and was followed less than an hour later by a Ml 4.5 and a strong aftershock
sequence midway between Escondido and Palm Springs CA at the following
epicenter:

O: 04NOV1935 04:03:55 33.5N 116.9W Ml=4.5 PAS South of Palm Springs, CA

For tracking data on Olga see:

http://www.wunderground.com/auto/HurricaneSite/tropical/tracking/at200117.html

Because a path from the northeast into the Caribbean also pushes
the Caribbean plate away from the North American plate reducing normal
stress across the boundary, earthquakes along this plate boundary are
also possible. In 1935 an earthquake of Mb6.3 occurred on Nov. 10
with the following parameters along the northeastern subduction zone
separating the North American plate from the Caribbean plate:

O: 10NOV1935 18:27:46 16.5N 62.5W MB=6.3 G-R Leeward Islands, Caribbean

Finally, since motion could be enhanced along the fault systems
separating the Pacific from the North American Plate, slippage
on some of thes faults could be promoted. For example as Hurricane
6 hit Florida, the following Ml 6.0 earthquake occurred in the
Gulf of California:

O: 04NOV1935 10:12:52 24.0N 110.0W Ml=6.0 ISS Gulf of California

The expected path of Ogla is slightly to the south of Hurricane 6,
and the actual seismic enhancement may be more concentrated along
the Caribbean/North American plate boundary this year. About all that
can be said at this time is that IF Olga continues on the forecast
track, there could be some very unusual seismicity if she hits
North America from the northeast.

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 29 is the fifteenth day after the beginning of 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

NE Europe MB>=4.0 11 2.5 0.04
Solomon Islands MB>=4.0 26 2.6 0.03
Japan MB>=4.0 16 2.4 0.04
Spain MB>=4.0 30 2.2 0.05

Regions expected to experience reverse triggering (i.e. they are
unlikely to experience a significant event at this period of the
lunar cycle) are:
