yep, you're absolutely right Frank, the Richter Scale is logarithmic, so, go up ONE number, and it's TEN times stronger.
The Richter Scale:

my daughter goes to San Jose State University, and I try not to worry.
and yes, the *soil* type matters.
the SF Marina district was built on bay-fill, compacted mud.
and those are the buildings that fell down, as the mud behaved
like Santa's BELLY, that shook when he laughed, like a bowl-full of JELLY
it's called liquefaction:
Although the effects of liquefaction have been long understood, it was more thoroughly brought to the attention of engineers and seismologists in the 1964 Niigata, Japan and Alaska earthquakes. It was also a major factor in the destruction in San Francisco's Marina District during the 1989 Loma Prieta earthquake.

oh, and yeah, I'm okay today... busy, busy, busy!!
three pregnant guineas, a preggers sow, and goats making happy-happy!
big day today, monthly journey over-land and take the hand-cranked ferry, to get sacks of feed... came home, fed everyone, stripped the bed, and did laundry.
argh!
the second sprained ankle this month, still swollen and throbbing, but I'm wearing my AFO's religiously, and walking more carefully.
and I definitely used the brand-spanking-NEW motorized cart at the grocery store.
I do believe it may be the ONLY one of it's kind in Belize, so I make SURE to effusively THANK the store owners (Mennonites) for providing it... and tell them, the longer I can SHOP, the more $$ they get from me!
so tired now, the bed's only HALF-made, gotta go STEEL myself to finish it.
maybe I can talk hubby into helping?
