landslides
khannula | November 9, 2009There's a great, new online news article by Science's Richard Kerr about the role of the Zipingpu Dam in last year's Wenchuan earthquake. A new article in Geophysical Research Letters (which I haven't read - my library doesn't have access to GRL) tests the plausibility of water as a trigger for the Wenchuan quake, and concludes that the weight of the water, combined with its penetration into the fault zone, might have made the difference.
There have been a number of studies in the past decade or so that suggest that earthquakes can be triggered by little things, such as the passage of…
khannula | November 1, 2009Go to Dave's Landslide Blog for full details about this. I don't have access to the paper.
According to Dave Petley, there's a new paper in Nature Geoscience about the Slumgullion landslide. Slumgullion is in my greater neighborhood - it's in Colorado's San Juan Mountains, between Lake City (former home of Alferd Packer) and Creede (former home of Doc Holliday), and I think it's got the coolest name of any landslide (and possibly the coolest name of any geological feature). It's a strange landslide for its slow movement, and it's being monitored in excruciating detail by the US Geological…
khannula | April 30, 2009I should have finished designing the new version of my disasters class. I've been thinking about it forever. But then I was trying to get a paper written, and then I went to a conference, and then there were senior thesis presentations and end-of-semester grading and a six-year-old's birthday, and, well...
Yes, I am frantically trying to get a syllabus ready for class on Monday.
I've got three more days (though they include a discussion with my soon-to-graduate thesis student, graduation, and a birthday party, so it can't be non-stop syllabus work). That means that, although I should be…
khannula | March 18, 2009I've been blogging my way throug the redesign of my upper-level general education course, "The Control of Nature," using a course design tutorial from SERC. I've talked about what's gone wrong in the past, about who my students are and what they need from the class, and about my tentative goals for the class. I've been mulling over the problem (and also going back to classes after spring break), and I've finally worked through the next part... the course plan.
When it comes time to put a course together, I've got some bad habits. For instance, when I don't have any good ideas, I start by…
khannula | March 13, 2009I'm rethinking one of my courses, an upper level general education course called "The Control of Nature." I've been blogging my way through the course redesign process, starting with past problems with the course and with my various practical constraints (class schedule, physical space, student background). I'm using an online tutorial to guide me through the process, and now I'm finally moving towards thinking about the course itself.
Before I actually start redesigning lectures and in-class exercises and assignments, I need to figure out what I want students to be able to do when they get…
khannula | March 11, 2009I've got a course that (IMO) is broken, and I'm working on fixing it.
I've been teaching a course called "The Control of Nature" (after John McPhee's book) for 16 years, after thinking of the idea on my way home from my first academic job interview. (Yes, that was a bad time to come up with an answer to a question like "what other class could you teach?" No, I didn't get that job.) I've taught it as an intro course for non-majors and as an upper-level interdisciplinary general education class, and I had plans, once, to adapt it for a freshman seminar and for a large-lecture gen ed class. It'…
