[pdx_life] Harmonic Volcanic Convergence

They remembered the word for the special sort of tremor Loo-wit is exhibiting right now: harmonic tremor.

What it is is sustained ground trembling brought on not by rocks breaking up but by the major movement of magma underground.

Sulfurous gasses have also been detected coming out of the crater, which is a sure sign of Something Coming Up. Now, fortunately, the mountain has not yet erupted, meaning I haven't missed my dream shots yet.

It will be something to see. Hopefully big enough to be somewhat spectacular, but there should be no life or property lost; the big cap of volcanic rock left us in 1980, and that was the reason for the huge explosion and great zone of damage, there is nobody living in the projected blast area. Volcanic ash wafting over Portland is possible but unlikely, as the prevailing winds generally go west to east.
