It all started when I was trying to find out what rock formations and rock types I was seeing while making the long trip to work and back out near Elko. Looking around, I found this geologic map (Smith and Ketner, 1972), which [...]
This is really good physics, something I don't expect from 'official' earthquake people. The video shows ground velocity which has a direct connection with damage. You can see the directivity of the giant thrust fault, and although it [...]
The organisers of the PATA Days 2017 in New Zealand have provided details on the planned field trips. There will be a 1-day field trip at the start of meeting, and an optional 3-day post-meeting field trip. Some of the field trip details are not yet [...]
The Foreknobs Formation is a Devonian unit in the Valley & Ridge province of the Mid-Atlantic Region. It was deposited in relatively shallow near-shore conditions during the Acadian Orogeny. On a field trip to Corridor H, a new highway [...]
Together with my colleagues I have published a new paper in which we describe a methodology for mapping the shallow architecture of large sedimentary basins with minimum effort and high resolution. We use two geophysical methods and combine them [...]
People living in the American Southwest have experienced a dramatic increase in windblown dust storms in the last two decades, likely driven by large-scale changes in sea surface temperature in the Pacific Ocean drying the region’s soil, according [...]
The new method of science is to seize an issue and then fight off any comers, like a game of 'King of the Castle'. I had a lot of fun with that as a kid, especially on giant snow piles.
The concept that seismic surveys do [...]
On Monday a significant rockslide on the flanks of Geiranger Fjord in Norway was captured on a video now posted to
Vienna: One of the most culturally rich and diverse capital cities in the world and home to this years’ European Geosciences Union (EGU) annual meeting. I was fortunate enough to attend this meeting during the first part of the week in … [...]
Brad Ross, a mining engineer, has provided extensive insights into the events leading up to the vast Manefay landslide at the Bingham Canyon mine in
