One view of this eruption is that we're at the end of the eruption that began in 1980.

This eruption has gotten increasingly sluggish. There's almost no gas being produced. We haven't had a big event since the (36,000 foot high) ash plume in March 2005, and we're feeling increasingly comfortable that we're looking at the sluggish end of this. ... I don't see how it can go on for another year without stalling.

One view of this eruption is that we're at the end of the eruption that began in 1980. If it hadn't been so cataclysmic . . . it might instead have gone through 30 or 40 years of dome-building and small explosions.

We haven't had that kind of plume since March 8, which is either a blessing or it leads us into complacency. We avoid complacency.
