Hollow stem auger strikes NY Subway Train [2014-11-07 06:39:25]  recommend  recommend this post  (17 visits) info

A 10 inch hollow stem auger grazed a packed subway car on the NY MTA's F line last week scratching the side of the train and breaking windows. Fortunately there were no injuries. I think the pictures say it all! The auger belonged to a contractor installing dewatering wells. But as one MTA source quoted in the Post put it: 'Somebody made a mistake; maybe a surveyor or a field engineer... They drilled into the street but didn’t realize they were right over the F train tunnel. [...]

Shotcrete Made From Tailings Could Insulate Underground Mines [2014-10-27 07:30:24]  recommend  recommend this post  (14 visits) info

Underground metal mines can have extremely high temperatures, making it hazardous for employees to work there for more than a few minutes at a time. Researchers from my alma mater, the University of Arizona, are studying the possibility of using a common mining waste product, tailings, as aggregate in shotcrete with good insulation properties that will be used to coat rock surfaces that readily conduct heat.

Alaskan megathrust fault more active under Kodiak [2014-10-23 08:27:48]  recommend  recommend this post  (38 visits) info

The 1964 Alaska Earthquake was 9.2 in magnitude and caused dramatic destruction and dramatic examples of surface rupture, subsidence, and liquefaction. New paleoseismic evidence points to a previously unknown earthquake that happened on the same fault segment approximately 500 years ago. This new evidence would change the recurrence interval for the earthquakes on the Alaskan megathrust fault, which would affect seismic hazard in Alaska, but could also increase the tsunami hazard in places as [...]
