In the tradition of girding against bygone debacles more than future
threats, both due to their searing memory and their ease of study,
considerable effort has been directed to reconstructing the 1906 San Francisco
earthquake and the 1811–1812 New Madrid earthquakes. The recurrence of
these M7 to M8 events may well bring a costly and deadly toll. However, as
earthquake cycles alternate between accumulation and release of strain energy,
both regions may still be early on their journey to the next earthquake, while
considerable and possibly greater danger lies elsewhere.
| On the volcanic front, the 1980 eruption of Mt. St. Helens is firmly in
our consciousness and monitoring effort, consistent with our
what-have-you-done-to-me-lately hazard mitigation attitude. Less clear in our
view are Mt. Hood looming over Portland and Mt. Rainier over Seattle.

The Cascadia subduction zone, with its overlying landslide-salted and
volcano-peppered mountains cradling the metropolises of Seattle, Portland, and
Tacoma, offers a counterpoint. This editorial, I admit, is motivated by the
daunting chore for the Pacific Northwest Seismic Network of shadow-boxing
threats the most recent appearances of which have not been documented by
Hearst newspapers and . . . [Full Text of this Article]
