This is the third post. Day One was Friday, and day two Saturday. I had to work on grading, lectures, and research yesterday, so I disconnected myself from the internet, but here a few more links about the Japanese earthquake from Friday for my students.
Last update: 9.30 CST, Monday, 14. March 2011
Science:
- I have to give credit to the seismologists out there — there is an amazing amount of scientific data already available from this earthquake
- earthquake slip distribution preliminary study using Japanese GPS data from Nagoya University (via @CPPGeophysics)
- Callan Bentley added a blog post that discusses the differences between “primary” and “secondary” effects of an earthquake
- GeoMika has a good primer into tsunami waves
- wondering if this type of tsunami damage could happen in the US? GeoMika discusses the potential for tsunami damage in the Pacific Northwest and California
- animation of a regional tsunami model from Kenji Satake (via @CPPGeophysics)
- very, very good image of the Hawaiian tidal gauges with red = modeled and black = what really happened (via @highlyanne)
- same type of diagram for the West Coast and Alaska (also from Anne)
- timeline of what’s going on at the nuclear power plants in Japan from @kate_sheppard
- table of tsunami travel times & heights for the Japanese coast – I had to navigate a bit, since linking directly to the data doesn’t seem to work (via @highlyanne)
- Dan’s Wild Wild Science Journal has a link to Dr. Josef Oehmen of MIT discussing the realistic hazards surrounding Japan’s nuclear power plants
- an earthquake vs. magnitude vs. time for the past few days from Japan from @Allochthonous
- disaster extent maps & tsunami inundation assessment from satellite images — yes, its in German, but you only need a few words (Schadenskarte = damage map; Erdbeben = earthquake) — the maps themselves are very, very well done & all labeled in English (via @geozon)
- tsunami deposits from the past vs. what happened on Friday post from paleoseismicity.org
- GPS displacement during (red) and after (blue) Friday’s earthquake — watch out for the fact the scales for red & blue are different! (via @callanbentley) — this is from the Sendai supersite, that has been expanded quite a bit over the weekend
- Trembling Earth post about the wide-spread reach of Friday’s earthquake, which includes a few seismographs
- The Great Beyond has a strong post about what’s going on with Japan’s nuclear plants
- Evelyn has had a follow-up interview with her dad the nuclear engineer (and the first one is now transcribed, btw)
- animation that explains the shifts in GPS data before & after Friday’s earthquake (via @stressrelated)
- the closest tidal gauge (Hokkaido) to where the tsunami struck is still seeing 1 meter waves! (via @highlyanne)
- NYTimes flash animations about the nuclear power plant in Japan (via @callanbentley)
- the official USGS poster about the earthquake has been released – you can download it in pdf format (via @volcanojw)
Photos / Videos:
- interactive damage map with photos and information from the NY Times (via @CPPGeophysics)
- before & after gallery of various damaged locations around Japan (I’ve lost where this link came from…)
- Boston Globe’s the Big Picture has added an aftermath sequence of pictures
- the first seven pictures from this person’s Facebook page (be mindful and respect the family’s privacy) are of damage the tsunami did in Kona, HI (via @callanbentley)
- The US Naval Commander in Japan has posted on his Facebook page a video & several pictures of the relief work that the US forces are currently involved in (via @cbdawson)
- Facebook video of the tsunami sweeping down a street – worth watching (via @callanbentley)
- the In Focus gallery of aftermath photos (different collection that the Globe’s for the great extent)
- Trembling Earth collected a nice set of videos of the shaking in Japan (and links to a few more)
Eye-witness accounts:
- seismologist at the University of Tokyo (via @sfoxx) where it was “business as usual”
More on the speculation side:
- there was a bit of twitter chatter (which I’ve now lost – sorry) about whether EQs can cause volcanic eruptions–Jessica at Magma Cum Laude wrote a post addressing this issue & what an earthquake might vs. probably won’t affect and Erik addresses the issue a bit at the end of this post
- meanwhile: Shinmoedake volcano in southern Japan resumed erupting over the weekend (via @CPPGeophysics)
I want to thank all of those who have been great about posting the links they find on Twitter–its been a great resource for finding information.
And finally, if you’re looking for another way to donate, I personally like CRS for their very, very low overhead so that more dollars get to those in need.
