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 [...]
What is this?!!1?1!?
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 [...]
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 [...]
On Monday a significant rockslide on the flanks of Geiranger Fjord in Norway was captured on a video now posted to
I pulled off for a pit stop at Bob Scott Summit and started seeing little tiny wildflowers everywhere. I looked around, hoping to see a superbloom, like so many were reporting this year, but the flowers were either somewhat far between, or—where [...]
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 [...]
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

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 [...]
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 [...]
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 [...]
