Don't Panic Geocast

Earthquake! Last week Oklahoma was rocked by the largest recorded earthquake recorded in the state’s history. We talk with Dr. Katie Keranen who is in the field deploying seismic instruments to study the event.

Sorry for the audio quality this week - we were recoding the interview as a phone call since Dr. Keranen was in the field and there are occasional dropouts.

A few weeks ago we finished collecting all of your limericks in our contest to win some sweet geo-swag from Chris at Taylor Custom. This week we are joined by special guest Katie Shearer to announce the winners and read more of our favorites! If you didn’t win, don’t fret, we are working with Chris on a top secret project and will be running another contest soon!

We are teaching and traveling with the start of the semester. Since John has no solid cell phone signal at a conference in New Hampshire and Shannon is swimming in lecturing, we wanted to share one of our favorite interviews from this year!

This week a special guest takes us to the moon by talking about lunar rocks and meteorites! The moon turns out to be a fascinating place, but probably won’t break up like in Seveneves.

Classes start next week - it’s time to evaluate what we did over the summer. How did our summer manifestos work out and what are we going to accomplish this fall?

• Defcon Seismometer Hack
• Seismo Live
• Techniques of Experimental Geoscience Webpage
• Spaceballs Combination Scene

• Figure out my future job
• Finish up a couple of instrumentation projects
• Assemble my dissertation
• Don’t let this class kill me

• Look for my replacement for Evernote
• Actually look at my to-do better next time list for classes
• Read all the literature!
• Submit a manuscript
• Have fun with my new class…geology of extreme climates

We are setting up a time to record with our judge, it may be a week or two, but hang in there. If you want to send in an audio recording of you performing your limerick, that would be awesome. Don’t forget - we have STICKERS!

Having just got back from vacationing near a river, Shannon’s mind is wondering (and wandering!) about dams and their impacts, both good and bad. People use dams for electricity, recreation, flood control, and a myriad of other things. Let’s take a look at some huge dams and what they do to both communities and rivers.

• Oroville (1968) is the tallest in the US, and earthen dam in CA 770’ high
• Hoover (1935) is next at 726’ high on the border of AZ and NV
• Tallest dam in the world is Jingping-I dam (2013) in China is 1000’ high
• Largest reservoir in the US is Lake Mead, which holds 29 million acre-feet of water
• Glen Canyon dam
• Lake Powell on the AZ/UT border, and is a close second at 26 million acre-feet capacity.
• Colorado River
• WPA

• Water supply
• Irrigation and flood control
• Power supply
• Recreation

• Hoover dam generates 4.5 billion kw-hr per year, serving 8 million people in AZ, southern CA and NV
• Itaipu dam, on the border of Brazil and Paraguay, dams the Parana River, the 7th largest in the world.
• Penstock

Forecasting the weather is tricky business. You need a lot of information. While surface observations can get us a lot of data, we still need information about what is happening far into the atmosphere to make meaningful models and predictions. Thats where weather balloons come in. This week we talk about how upper air observation works as well as Jupiter’s atmosphere on Fun Paper Friday!

• Pilot Balloons
• Real Time Sounding Data
• Hodograph
• Skew-T
• Tephigram
• Stuve diagram
• High altitude research balloons
• Near space hobbyists
• NOAA Radiosonde Fact Sheet
• GPS occultation to measure atmospheric profiles
