[quote:AKObserver:MV8xNDQ3NzA2XzM5ODQzMzI4X0FEQ0Y0NTdG] For some reason I started looking at all of this again the other night went back several months before this event found EQ activity like we've been seeing first in Aleutian trench/Kodiak area then Cape Yakutat 'the elbow' and Queen Charlotte Island The Denali fault is an active intracontinental right-lateral strike-slip fault that accommodates a fraction of the oblique collision of the Yakutat block into the southern Alaska margin. It is the northern boundary of a region being extruded to the west. The Totschunda fault splays off the Denali fault and strikes 14° more to the southeast. The Totschunda fault is parallel to and aligned with the plate-bounding Queen Charlotte–Fairweather transform fault system further south, and it may be part of a developing connection between the Fairweather and western Denali faults. The Alaska Range is adjacent to the Denali fault, and the high topography of the range may be related to thrust faults that merge into the Denali fault at depth. That quake we just had is almost where the first 2002 quake hit. It's on the Susitna Glacier fault which converges with the Denali-Totschunda fault junction. The Denali fault earthquake sequence began with the moment magnitude 6.7 Nenana Mountain earthquake on 23 October 2002. This event was followed by numerous aftershocks that ran a 45-km-long zone along the Denali fault. The aftershock zone stopped 10 km west of the 7.9 Denali-Totshunda Fault Earthquake on Nov 03, 2002 epicenter. The findings showed right-lateral strike-slip, consistent with rupture on the Denali fault. The thing that really caught my attention is the areas effected by the S-waves and the areas that seismic activity was triggered are places we have seen activity in the last few weeks The Denali fault event triggered local earthquake activity at distances as far as 3660 km. Of seven documented instances of triggered seismicity, six are located in volcanic or geothermal activity areas: (1) the Katmai volcanic field in Alaska, (2) Mount Rainier in central Washington (3) Yellowstone caldera in Wyoming, (4) the Geysers geothermal field in northern California, (5) Long Valley caldera in east-central California, and (6) the Coso geothermal field in southeastern California. The other site is along the Wasatch fault zone, central Utah. The triggered seismicity developed rapid sequences of small local mag earthquakes ranging from several minutes in the case of Mount Rainier to days in the case of Yellowstone. Yellowstone caldera, nearly in line with the rupture propagation direction, produced the most active response swarms continued for at least 10 days. The earthquakes covered the entire volcanic field and were accompanied by unusual variations in geothermal activity. Katmai is the only one of the many active Alaskan volcanoes that showed triggered seismicity. Veniaminof and Wrangell volcanoes showed decreases in seismicity beginning several days afterwards. http://www.aeic.alaska.edu/html_docs/aeic_research.html http://www.aeic.alaska.edu/html_docs/monthly_reports.html The 2002 M7.9 Denali Fault earthquake in Alaska caused a 2-foot water-level rise in a well in Wisconsin, more than a thousand miles from the epicenter. The other type of ground-water response is a water-level oscillation, which occurs more often, but is less commonly recorded. In the few cases where oscillations have been recorded, they resemble long-period seismograms, known as hydroseismograms. A well in Grants Pass, Oregon, is instrumented to record water levels at 1-second intervals, and the record from the Denali Fault earthquake shows peak-to-peak seismic oscillations of more than 4 feet and a permanent offset of 0.4 feet After the Denali Fault earthquake, many eyewitnesses throughout the contiguous United States reported water “sloshing” back and forth in lakes, bayous, ponds, and pools. Seiches lasted as long as half an hour, resulting in broken moorings in Lake Pontchartrain, Louisiana(Seth Moran, U.S. Geological Survey, written commun., 2002)- boats reportedly sank in Assumption Parrish, Bayou Corne peopleofthekeys.com. Beats me what pulled me back to all of this but now looking at it wondering... Right now we do not have LISS available in the event of a large quake, we are seeing increased activity in the above areas, if Alaska had another big quake what would that do to the current Bayou Corne sinkhole situation? Would Seiches cause the whole salt dome to collapse? IDK...something to ponder...just putting it out there. [/quote]

Its going around the ring... South America next.
UPDATE......UPDATE.....UPDATE
For anyone interested in Earthquake predictions:
I guessed 2 that have hit by looking at the above link and seeing a pattern. I'm talking above 4.0 Mags. Please take a look and tell me where you think the next one is going to be and why.
