I also have noticed that circle pattern of quakes in the Pacific Northwest. I have seen it show up, off and on, for several years. On the recent
earthquakes map, sometimes the entire circle clearly shows up, sometimes just parts of it. I am interested in Impact Craters and earthquakes. Could
this be evidence of an ancient 600 mile wide impact crater? Could the giant impact crater also be the cause of the Yellowstone hot spot?
I have observed this pattern occuring for several years on the USGS Recent Earthquakes in USA website.

It circles from Oregon, through Washington, almost to Canada, Idaho, then over through Montana down to Yellowstone Park, down through Wyoming and
Utah, and part way into Nevada and California, then back to Oregon
I still strongly feel that there is definately something there. If you look at the Google Map view of the Pacific Northwest, in the Satellite view,
or Terrain view.... you can also see this gigantic 600 mile wide circle in the landscape. It is there. There also appears to be a raised area in the
center, like a bulls eye.

If impact craters may have possibly effected the geological formation of mountain ranges, such as the Ural Mountain Range in Russia, could a giant
impact crater in the Pacific Northwest also effect the geological formation of the Cascades and the Rockies? Oil companies do look for circular
formation patterns in earthquakes, to locate ancient impact craters, to find oil and gas deposites. At the Panther Mountain Impact Site, fractures
along the rim of the impact crater are weaknesses in the rock, which allow water to wear away and create circular patterns in the landscape. Could a
giant impact crater also cause huge fractures going deep into the earth's crust, allowing magma to rise up through these weak areas, and create the
volcanoes in the Cascade mountains to form a curve along the left side of the impact crater rim? Gigantic Lunar Impact Craters do have vast areas of
flood basalt. Could this giant impact crater in the Pacific Northwest be the cause of the Columbia River Flood Basalt which covers 63,000 square
miles, and is up to 6,000 feet thick in some areas? Could the giant impact crater also be the cause of the Yellowstone hot spot?
This circular pattern of earthquakes on the USGS Recent Earthquakes page has continued to show up for several years. Their animation page shows just
one week at a time. I have watched this site for several years, most of the time on a daily basis, and it continues to show up. Sometimes part of the
circle shows, and other times a complete circle of quakes. If you look at data from USGS, of the earthquakes in that area, for the past few months or
years, you will see that the circular pattern is there. The latest date of the most complete 600 mile wide circle I saw was on December 19, 2007. If
you could get access to data on that date ( December 19, 2007) , you will see that circle. The animation on that USGS web site shows the quakes that
happened in the United States in the previous 7 days.
