Splish Splash

No secret that I’m fascinated by waves.  Call me Doctor Doom, but the bigger the better.  One source of big ones is asteroid impact. 

I’ve blogged here before about these things

Blogging at social.openhazards.com

Lately I have been blogging over at our social site, where everyone interested in hazards and risk is welcome to open an account, post content, and participate.  Or just visit as an anonymous visitor and read the various postings.  I plan to use the site in my classroom teaching next winter, and it is already being used by some students at UC Davis.

Venezuela Earthquake M6.1 October 11, 2013

An earthquake having moment magnitude 6.1 occurred at 9:40 pm local time.  Located on the boundary of the Carribbean and South American tectonic plates, this event had both thrust (compressional) and strike slip (horizontal slip) components.  As an offshore event, it could be anticipated that there would not be significant damage or injuries.

China Syndrome

Last time I asked that you stay tuned for the ‘Worst Dam Disaster in History’.  From the title of this blog you might guess where that happened.  Yep, China.  The year, 1975 – not that long ago really.

From the late 1950’s to mid 1970’s, China went on a dam building binge. Lacking local talent, Russians largely supervised the design, engineering, and construction of 100s of dams. Impoundment and distribution of irrigation water to grow food for the masses drove the frenzy.
