Ah, yes! They're constants, aren't they?

And you, too, Jackie [HUGS]! Would those guards be constant constables, then? And thanks for the link, Fr Steve...Neat!

I'd heard Mt St Helens was "hotting up" again. What's the skinny on it, Padre?

The mountain never "cooled off" but has been in what is described as a constant state of eruption since the big one. A "constant state of eruption" can sometimes mean no more than that the dome in the middle of the crater is growing (lifting) in small but measurable ways. Other times it is more violent and dramatic, e.g. steam jets, ash plumes, rock slides and the like. A new word -- lahar -- has entered the vocabulary of folks around here. I think it comes from Indonesia. It means flows of mud and debris which can sluice down the side of a volcano. It happens in places where it rains a lot .. like here! The kids who go to school in the shadow of the mountain now have to learn lahar evacuation routes and procedures, much as we learned how to hide under our desks in the event of an atom bomb attack when I was in elementary school.

Thanks Padre. Yep, I understand volcanism to some extent - NZ being a particularly bubbly kind of a place. A lahar off Mt Ruapehu in 1953 wiped out a rail bridge, causing the overnight express between Wellington and Auckland to plunge into a river killing a lot of people. Tje rail line was nearly five miles away from the crater.
I was curious to know if Mt St Helens had shown any greater propensity to erupt than usual. Mt Tarawera did exactly what Mt St Helens did in 1863, although it was much smaller than Mt St Helens. The scars are still visible even today.
