Shallow thrust earthquake hits Taiwan


M6.4, very small in this region, but location makes the difference.

In general, nobody builds better than Taiwan, but this has spaghetti rebar, and weak concrete.  We'll have to see what the strong motion was, especially the PGV.  They know how to record strong motion, unlike anybody else.

For this type of damage, we need a PGV over 1 m/s and this building is on soft soil.  We will learn a lot from this earthquake, mainly how useless 'early warning' is.  Most of all, this is not a 'plate margin' earthquake.  This is an Oklahoma and Toronto earthquake.  It all depends on where the 'hammer' of the thrust is.  Looking at the data, these towns were right in the hammer zone.

ps.  In any picture of an earthquake disaster, look at the buildings with no damage.


Wow, thank goodness no major aftershocks, which we would not expect from a clean thrust.

Got the Crown Royal!

A truck just rolled up to the local LCBO.  A web alert went out, and my son fought the crowds to get the bottle.  Magnificent, rolls on the tongue like ambrosia.  A hint of cloves and spice.  Too bad you can't get it.  :)

** oh man, am I being evil.

New Webisode Series - My Geotechnical Nightmare

I'll being doing a series of these on YouTube.  I can jump around and yt fixes it like I have a steady cam.

My brain refuses to accept this as reality.  You are viewing images from a crazy brain.  Be warned, do not view this if you are having anger issues, take a pill first.

ps.  I won't be doing any more of these until they destroy a lot more land.  They are going to put a bridge to the other side, and then excavate a road to lay down the new riprap.  I'll wait until something happens.
