Update....from AVO

Intense seismicity continues at Redoubt this afternoon. Clear webcam views, satellite, and radar data from earlier today indicate that the volcano has not yet erupted.

Clouds have moved in to obscure the webcam view over the last hour.

An AVO observation flight returned in the last hour and reports no sign of ash emission, but observed significant steaming from a new melt depression at the mouth of the summit crater near the vent area of the 1989-90 eruption.

The Aviation Color Code remains at ORANGE and the Volcano Alert Level remains at WATCH.

From MN DNR...how Pinatubo affected the Walleye population in the 1990's

Schupp also authored a scientific paper theorizing that atmospheric ash from the 1991 Mount Pinatubo volcano eruption in the Philippines was to blame for the poor walleye fishing throughout Minnesota in the 1990s. Climatologists say the ash from the massive explosion drifted east and blocked sunlight from reaching much of North America and Europe, causing the cold, wet summers of 1991 and 1992. Because the cool summers didn't create good conditions for the production of walleye fry or perch fry, the walleye year-classes those two years suffered.

Schupp says, "People blamed the DNR stocking program, but the major factor was Mount Pinatubo."

Colby, the Ontario walleye guru, agrees. "There's no doubt in my mind that Denny is absolutely right about that," he says.
