Subject: Re: Minor Earthquake in Kent
A 4.7 isn't my idea of a quake. I live in
California. I rarely even wake
up for ones this size.
I slept through a 4.1 once, and I've never actually felt a quake (that I
recognized as such).
Given how buildings are constructed in southeast England, though, a 4.7
would be pretty noticeable. All the buildings that wee built that way in
California have been destroyed by earthquakes already, or extensively
retrofitted so that masonry won't collapse.
The quake in Bam, Iran in 2005 killed thousands (perhaps tens of thousands)
but it was weaker than the Loma Prieta and Northridge quakes in California a
few years ago, and those quakes only killed a few dozen people each. Not to
belittle the death tolls, but the building techniques in California are much
better than they are in other seismically active regions.
I bet if you had a 4.7 in Missouri or Arkansas there'd be a lot of damage,
and the scary thing is that the largest quakes in continental US history
occurred there (read up on the New Madrid fault).
