- On Earth Science Erratics, Erin Johnson tells us about the surprising lessons you learn when teaching Earth Science, including the willingness of students to boldly put their tongues where dozens of dirty hands have been before.
- Meanwhile Metageologist is trying to get more evidence to support his observation that geology may have more than its fair share of left-handers. The more geologists we can survey, the better!
The current rolling tally from a poll of Twitter is 33% lefties, 15% ambidextorous and 52% righties from 33 geotweeps:
Anniversary of the Tohuku Earthquake
It is one year today since a magnitude 9.0 earthquake and accompanying tsunami devastated the east coast of Japan, prompting many stories about the event and its aftermath.
- A compelling set of ‘Then and Now’ pictures for places hit by the Japanese Tsunami from the Big Picture:
- A Nature News special marking the anniversary has many good pieces, Rich Monastersky on tsunami forecasts/
- Sped-up recordings of seismic waves from the Tohuku quake make them perceptible to human hearing. The record of triggered tremor on the San Andreas Fault is especially interesting
- Lessons from Tohuku earthquake, tsunami, and the Fukushima nuclear accident: “Crisis management requires us to imagine what may be outside our imagination”
- This documentary on the struggle to control the Fukushima nuclear plant after the tsunami hit is well worth a watch.
- Critical NYT op-ed argues Fukushima accident was mainly due to international nuclear safety standards being ignored.
- The Fukushima accident is certainly casting a shadow over the prospects for nuclear power in the US, but economics is also an issue. This article at Ars Technica argues that high costs mean any ‘nuclear renaissance’ is going to be slow.
The Economist also weights in on why nuclear reactors are expensive and likely to remain so.

- Where did newspapers get quotes when Eyjafjallajokull erupted? Representatives of the aviation industry drowned out scientists, it seems. I’m shocked.
