BOOM Possible This Morning (25. November 2009, 09:22 by Derek Young) ~ Did you hear a thump?

We just received word that there may be a Big Boom coming from the tideflats this morning. Port of Tacoma contractors will be using light explosives on the former Kaiser Aluminum site on the east side of the Blair Waterway. So … it’s nothing to worry about.

A licensed explosives technician is scheduled mid morning to detonate a charge to break off a two-inch steel pipe in a water well about 750 feet below the ground. This work is in preparation for decommissioning deep wells on the site that once provided water to the former aluminum plant.

At 750ft under ground what are the chances we’ll even hear it?

Especially considering it’s probably 750 feet deep in sand, being in the tideflats and all. I can’t imagine sand conducts vibrations very well at all. If it were near bedrock, it seems more likely we might feel some rippling vibrations though.
