ONLY FAR_FIELD AFTERSHOCKS FROM HONSHU APPEAR IN GLOBAL EARTHQUAKE LISTS TODAY SUMMARY Far-field aftershocks (FFA) from the Mw 6.5 earthquake in Honshu yesterday began immediately and continued throughout the day today. Every event of Ml>=3.5 listed since the Honshu quake in the NEIS listing can be identified as an FFA of that Japanese event (9 straight events) The largest event of the day occurred in the Fiji Islands (Mb 5.7) which was identified as a likely location for FFA in the forecast: "71-73 degrees: ... Fiji Islands," The second largest event was a Mb 5.3 occurring at 19S in the Chile-Bolivia border zone at 146 degrees from Honshu as noted in the forecast: "142-146 degrees: So. Peru (14-19S)" The first earthquake listed by NEIS after Honshu occurred in Irian Jaya almost due south of the Honshu mainshock at 44 degrees from that event, and was also identified in the FFA forecast: "43-45 degrees: Myanmar, Nepal/No. India, Halmahera, Celebes, So. Alaska (Seward/Anchorage), New Britain" Also occurring at 43-45 degrees from Honshu were the following NEIS listed earthquakes: Sikkim/No. India Mb 4.9 - 45 degrees distance Southern Alaska Mb>3 (two events) - 45 degrees distance Banda Sea Mb 4.8 - 45 degrees distance (reported by GSSC) Other events listed by NEIS since the Honshu earthquake occurred at Chiapas Mexico (Mb 4.3) at a distance of 106 degrees from Honshu and listed in the FFA forecast as: "103-107 degrees***: Chiapas, Mexico" and an earthquake of Mb 4.1 in eastern Turkey at a distance of 72 degrees from Honshu and listed in the forecast as: "71-73 degrees: ... Eastern Turkey" Also occurring this afternoon near Napa, CA was a Ml 2.8, a relatively rare event for this area. This earthquake occurred at 71 degrees from the Honshu earthquake. The FFA forecast map can be viewed at: http://www.earthwaves.org/wwwboard/messages/11461.html GLOBAL There was NO global activity today listed by teleseismic networks which was NOT forecast FFA from the Honshu earthquake (Mw 6.5). U.S./CANADA The strong swarms of earthquakes in volcanic or hydrothermal regions linked to the Honshu earthquake surface waves (see yesterday's report) continued today at a reduced level. These swarms are occurring primarily at Mammoth Lakes, CA, Yellowstone, N.P. WY, and Mt. Hood, OR. The Mammoth Lakes Ml 3.4, the largest in more than a year in the region, also coincided with the start of the largest solar flare of the day - an M2.2 class (see Solar/Geomagnetic section below), and may have been immediately triggered by that flare as Mammoth Lakes was nearly sub-solar at the time. An earthquake of Ml 2.7 also occurred this afternoon in the New Madrid fault zone, Missouri/ Tennessee. This is the largest event in this area in nearly 5 months (since July 7, 2001). This event lies at 107 degrees from the Kunlun Mts. mainshock and may be an FFA from that event with additional input from the Honshu quake. In the California/Nevada region, besides the Napa (Ml 2.8) and Mammoth Lakes events (Ml 3.4), earthquakes of Ml>=2 occurred in the southland near Obsidian Butte (Ml 2.5, 2.4, 2.1) and near Coso Junction (Ml 2.1). Both areas are considered volcanic/plutonic hot spots. Activity also appeared to be returning to the L.A. basin area where events of Ml 1.9 occurred since last report near Leo Carrillo State Beach and Newport Beach. In the Pacific Northwest, the activity at Mt. Hood Oregon, continued with earthquakes of Ml 2.4, 2.1 and 2.6 recorded (for further details see yesterday's report). Earthquakes in the Yellowstone Park area increased in size and number following the Honshu quake. In the three hours after the quake in Japan, Yellowstone experienced three events of Ml>=2 (2.0, 2.1, 2.2) as many as had been listed in the previous 6 days. Two earthquakes of Ml 1.9 were also recorded northwest of Yellowstone at this time. An earthquake of Ml 2.9, the largest in Hawaii in the past two weeks was also recorded yesterday after the Honshu quake. Hawaii lies at 58 degrees from that event. The Canadian Geological Survey had not yet published data for events following the Honshu earthquake at this writing. NEW ZEALAND Strong activity in the New Zealand region followed the Honshu mainshock after a day of very quiet regional conditions. IGNS reported a Ml 3.7 and Ml 3.9 near Dannevirke, North Island and Kaikoura, South Island respectively within 4 hours of the Honshu earthquake. Activity also continued in the region south of the Kermadec Islands. The IGNS on-line Seismometer can be found at: http://www.gns.cri.nz/news/earthquakes/latest_drum.html GEOMAGNETIC/SOLAR FIELDS The geomagnetic field remained quiet since last report, although SEC expects active conditions to begin today. An M2.0 solar flare was observed last night (Dec. 2) with the following parameters: Flare # START MAX END CLASS 8850 + 2125 2206 2229 M2.0 The Ml 3.4 earthquake in Mammoth Lakes occurred about 2 minutes after this flare began and while the Mammoth Lakes region was near sub-solar. The earthquake had the following parameters and was followed by a strong aftershock sequence: O: 02DEC2001 21:26:49 37.5N 118.8W Ml=3.4 NCSN SE of Mammoth Lakes, CA A Ml 2.0 was also recorded in Germany about the same time: O: 02DEC2001 21:32:13 49.5N 7.1E Ml=2.0 LED GERMANY For general space weather conditions see: http://sec.noaa.gov/today.html For Solar flare data see: http://sec.noaa.gov/ftpdir/indices/events/20011119events.txt TROPICAL STORMS OLGA
Tropical Storm Olga is off the coast of Florida today and expected to stall over the Gulf Stream for at least the next three days. If she gains intensity, her next move can probably not be anticipated at this time. An earthquake was recorded in the Swan Fracture zone this evening by CASC, but we await confirmation of this event. This is one region where Olga was expected to promote local seismicity. For more on TD Olga's path see: http://www.wunderground.com/auto/HurricaneSite/tropical/tracking/at200117.html BESSI-BAKO Tropical Cyclone Bessi-Bako continues in the South Indian Ocean and is moving slowly to the south-southeast. This storm is not expected to impact regional seismicity significantly. For more details see: http://www.wunderground.com/auto/HurricaneSite/tropical/sp200101.public.html 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. December 04 is the twentieth 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 Central US MB>=1.0 63 2.7 0.03 India MB>=4.0 49 2.1 0.05 N So.

The largest events are most likely to occur 4-6 days following the storm, i.e. on November 30 to December 2, 2001 and are most likely to occur in one of these longitude bands and/or at high latitudes. ...
