Aftershocks
Since Tuesday’s big earthquake, we’ve had 5* aftershocks in the same area (and possibly on the same fault). The most recent one popped off last night at 1am. Here’s a plot showing the size of the events (moment magnitude) relative to the passing of time: Note that the quakes that came after “the big one” are smaller in their size (the amount of energy that they release into the surrounding …

My best flutes
Fellow geobloggers Brian and Eric have been getting all flutey on us lately, so I figure it’s a good time to show my best photo of flute casts: As the annotated copy suggests, this was taken on the side of the Pennsylvania Turnpike back in March 2008, when four Honors students and I drove up to Buffalo for a northeastern section GSA meeting. The strata are probably Devonian in age, …

U.S. Geoblogger Tour 2011
These are the geobloggers that I was privileged enough to hang out with this last week, in chronological order: Steve Gough of Riparian Rap: Ed Adams of Geology Happens: Evelyn Mervine of Georneys: Alton Dooley of Updates From the Vertebrate Paleontology Lab: Garry Hayes of Geotripper: Geobloggers are good people. They blog because they like to share their enthusiasm for the geosciences, and this also makes them fun people to …

Bulletin board
A few items for your perusal… Simon Winchester wrote an article that made a lot of geologists cringe; then he wrote another that dug the hole deeper. If you haven’t been following the conversation on Twitter, then you can play catch up. Some of us geobloggery types are submitting a letter to the Newsweek editor and one of the authors Winchester cites (while misspelling her name) is writing to the …

The visitors
Visitation statistics for Mountain Beltway over the past month and a half. Interesting to think about the implications… Should I do more current events blogging?

This is a friendly reminder that you have one more week to prepare your brownies, cakes, puddings, eclairs, gumballs, gobstoppers, and cookies for the Accretionary Wedge Bake Sale. The deadline for the submission of entries is a week from tomorrow, next Friday, January 28. Leave a link in the comments here, or at the original post. As an example of a coincidence that reinforces the “Bake Sale” theme, here’s an …

Blogger deserves GSA History Award
Join me in nominating David Bressan’s History of Geology blog for the Geological Society of America’s Mary C. Rabbitt History of Geology Award. To my knowledge, this would be the first time a blogger has won that honor. Every time I read one of David’s posts, I learn something new. I think it’s a wonderful service that he provides. Who among you appreciate David’s efforts enough to support the application …

Call for posts: AW#30, the Bake Sale
Recent discussion of the geologically incorrect cake t-shirt at Threadless (earlier take-down here) and the actual baked equivalent have inspired me to issue a call for Accretionary Wedge #30: Let’s have a Bake Sale! I hereby challenge my fellow geobloggers (and any newbies who want to participate) to explore the interconnections between geology and food. This can take any form you want, but I’m really hoping for some edible, geologically …

Travels of 2010
I’ve been asked to put up a post detailing travels from the year now concluding. You got it! The first day of January dawned for me in Buenos Aires, Argentina. I had just gotten done with one of the best trips I’ve ever taken, to Patagonia in December 2009. The capital of Argentina was a stop-over for a few days on the route back north to DC. On New Year’s …

AGU, day 4
My final day at AGU was Thursday, and I spent a lot of it working on school stuff, but I did zip down to the Moscone Center for a session on communicating science to the public in an age of increased public scrutiny. Michael Mann of Penn State was the big draw here, discussing his experiences being subject to the “Climategate” email flap, Freedom of Information Act requests from James …
