Yikes! https://t.co/Kr51GFSS7p— Ron Schott ⚒ · Wed, Feb 08 2017 04:23:46I suspect the spillway is going to be a total loss before this rainy season is out. Thank goodness it isn't immediately adjacent to the dam. https://t.co/yFh8bN21wv— Ron Schott ⚒ · Thu, Feb 09 2017 01:29:57Pray the underlying bedrock can withstand the punishment. I don't see how they're going to fix this between storms. https://t.co/SLa4lfgtrJ— Ron Schott ⚒ · Thu, Feb 09 2017 01:32:06.@SierraGeology Type of bedrock & things like jointing patterns will make a difference. Oroville spillway is on bedrock mapped as volcanics.— Ron Schott ⚒ · Thu, Feb 09 2017 02:52:26.@SierraGeology Oh, of course. That goes without saying. Nobody in their right mind is rooting for a disaster.— Ron Schott ⚒ · Thu, Feb 09 2017 02:54:20The damage to Oroville Dam spillway is serious.

Bogoslof Eruption, 9 Jan 2017

#storify-minimal a:hover{text-decoration:none}My Tweets leading up to and during this eruption of Bogoslof Volcano, Alaska.Storified by Ron Schott · Mon, Jan 09 2017 08:52:25Meanwhile, in Alaska... I get the feeling that Bogoslof is building up to something... https://t.co/QLYaOt8Gc6 · Ron Schott ⚒The seismic crisis at Bogoslof continues to escalate. I suspect an eruption is imminent. (However, I am not an expert in volcano seismology) https://t.co/Sphwlcq4FO · Ron Schott ⚒AVO Bogoslof ORANGE/WATCH - Increase in seismicity suggests eruption may be imminent or occurring. https://t.co/1sKEzRd9Nf— Alaska AVO · Mon, Jan 09 2017 07:32:20@rschott Which seismometer is this from? I thought there wasn't one on the island?— Oliver Lamb 🌋 · Mon, Jan 09 2017 07:32:25@olamb245 I'm watching OKER https://t.co/y2OLCfJj7n— Ron Schott ⚒ · Mon, Jan 09 2017 07:34:44@rschott Station OKRE has clearer quakes. I can't be sure, but it looks like classic sequence of eqs morphing into tremor. Very impressive.— Oliver Lamb 🌋 · Mon, Jan 09 2017 07:43:51Boom! https://t.co/AKs6uu6G8a · Ron Schott ⚒And now the seismicity is subsiding. I saw no lightning strikes associated with this episode, so full-blown eruption is unlikely. So far. https://t.co/eXluLIUTph · Ron Schott ⚒AVO Bogoslof RED/WARNING - Explosive eruption started about 22:23 AKST (07:23 Jan 9 UTC). https://t.co/1sKEzRd9Nf— Alaska AVO · Mon, Jan 09 2017 07:54:57Looks like the seismicity at Bogoslof is picking up again. Lack of lightning may also suggest eruption is interacting with less seawater(?). https://t.co/Cw8kmSZLlL · Ron Schott ⚒There's the lightning. It's an eruption for sure! https://t.co/tXdlvJoDy7 · Ron Schott ⚒Bogoslof eruption cloud growing. https://t.co/mSqIYXs9ad · Ron Schott ⚒Bogoslof eruption looks to be winding down now based on the seismicity. https://t.co/8zUEYuWkqa · Ron Schott ⚒Seeing a geologic process unfold remotely in real time and having the scientific background to understand it gives me great satisfaction.— Ron Schott ⚒ · Mon, Jan 09 2017 08:23:25... especially when it doesn't kill or harm folks.

GeoEd: Demuddying the Reading

#storify-minimal a:hover{text-decoration:none}Methods for identifying misunderstandings and misconceptions from assigned reading in geology.Storified by Ron Schott · Tue, Dec 30 2014 03:43:57Spring intro course idea. Pre-class ?s each day - "one thing confusing in reading;" "explain concept that was confusing yesterday."— Kim Hannula · Mon, Dec 29 2014 22:00:02I'm not going to go fully into a flipped classroom, because recording lectures horrifies me. But thinking about reading might be similar?— Kim Hannula · Mon, Dec 29 2014 22:01:16Probably need to make deadline midnight of night before, to allow time to read ?s and organize responses.— Kim Hannula · Mon, Dec 29 2014 22:04:13Want to make students responsible for thinking about what they don't understand, & then for trying to understand it.— Kim Hannula · Mon, Dec 29 2014 22:06:40@stressrelated Using the "muddiest point" technique, I see - will be quite effective!— Dr. G · Mon, Dec 29 2014 22:37:19@guertin Do you phrase it that way - "what was the muddiest point in the reading?" Or "What was the most confusing thing in the reading?"— Kim Hannula · Mon, Dec 29 2014 22:38:57@stressrelated Adding Just-in-Time Teaching (JiTT) to the mix. I use JiTT and it really helps keep non-majors engaged— Dr. G · Mon, Dec 29 2014 22:39:34@guertin BTW, this idea is totally stolen from @kaatgeo .— Kim Hannula · Mon, Dec 29 2014 22:39:37@guertin My one fear is that I won't have time to read what they've written before class. I'm not teaching until 10 am, so maybe...— Kim Hannula · Mon, Dec 29 2014 22:41:14@stressrelated They don't know what "muddiest point" means, I've found. Use terms you know your students will understand/be comfortable with— Dr. G · Mon, Dec 29 2014 22:44:20@stressrelated are you requiring students to write something? If optional, most students will write down, "no problems" (even if there are)— Dr. G · Mon, Dec 29 2014 22:46:01@stressrelated What I've seen... Most concerns/questions are the same, I've been able to go through ~60 morning of class, no problem— Dr. G · Mon, Dec 29 2014 22:48:14@stressrelated Some students submit responses early, so you can review early. you make me wish I finished that JiTT paper I started writing!— Dr. G · Mon, Dec 29 2014 22:49:58@guertin Yes. I've been requiring pre-class questions anyway, so adding this won't be bad.— Kim Hannula · Mon, Dec 29 2014 22:50:10@guertin Have you had students re-visit their questions? I'm trying to find ways to get them to keep working on their misconceptions.— Kim Hannula · Mon, Dec 29 2014 22:53:01@stressrelated Not in a "graded response" way - which now gets in to "how much time can we spend/revisit one topic in one semester"?— Dr. G · Mon, Dec 29 2014 22:55:45@stressrelated With general education courses, worth getting those mis-/nonunderstandings cleared up (as I'm their 1st/last geo course)— Dr. G · Mon, Dec 29 2014 22:58:05@guertin Maybe I'll add an open-response question to the weekly (open-book, online) quiz - "explain one concept that was unclear in reading"— Kim Hannula · Tue, Dec 30 2014 00:08:19@stressrelated @guertin IME, you'll still get people who say they understood everything.— Anne Jefferson · Tue, Dec 30 2014 00:10:01@stressrelated @guertin I've had better luck asking what they still want to learn. Some will ask for clarity, others will reveal misconcepts— Anne Jefferson · Tue, Dec 30 2014 00:10:47[...]

Learning About Deep Sea Sedimentation from #Exp342

Sun, 15 Jul 2012 04:29:04 GMT

#storify-minimal a:hover{text-decoration:none}I learned a little something about deep sea sedimentation and sediment lithification that I didn't know before thanks to a Twittter exchange this evening with Brian Romans, a sedimentologist on the drilling ship Joides Resolution off the coast of Newfoundland.Storified by Ron Schott · Sun, Jul 15 2012 04:29:04TamuBeautiful new cores from the early and middle Eocene are on deck - our paleontologists are thrilled.
