More Iceland fault line pics here.
Þingvellir [thing-vet-lir] Fault, east of Reykjavik, is what Europe and North America being driven apart looks like.
Iceland’s Grímsvötnd volcano goes back to sleep. Video of it’s last gasps here (click the Play button).
Earlier today I posted a picture of the final activity in the Grímsvötn eruption along with some info. However this video is much better. Check it out. The site is in Icelandic, but to see the video just click “Horfa á myndskeið með frétt” at the top of the article.
Exclusive video of Grimsvotn volcano, Iceland. Keflavik Airport is shut down. All Iceland flights canceled.
Iceland’s imposed a flight ban and closed its main airport after the country’s most active volcano, Grimsvotn, erupted. It lies under the uninhabited Vatnajokull glacier in southeast Iceland and has been dormant for 7 years. A large plume of smoke and ash is stretching 20 km into the air. Iceland’s Meteorological Office says that the eruption at the Grimsvotn volcano has been accompanied by a series of small earthquakes. Scientists have been expecting a new eruption and have said previously that this volcano’s eruption will likely be small and should not lead to the air travel chaos caused in April 2010 by ash from the Eyjafjallajokul volcano
Excellent intro on how seismic sensors work, and how it helps urban planners.
BGS seismology | A brief introduction (by bgschannel)
Seismologist Dr Brian Baptie gives a short introduction to our earthquake monitoring work from one of the seismology laboratories at the British Geological Survey office in Edinburgh.
Evacuation center. Japan.
This weekend, the Washington Post took a look at the safety of nuclear power in comparison to other sources (like coal) in the wake of the Fukushima disaster. When the future effects of climate change are included, nuclear comes out way ahead. But when compared to the visible and potent disaster in Japan, long-term dangers (even if they are worse) seem like they are unlikely to sway critics.
People just aren’t very good dealing with the future. They’d rather be safer now.
Over 110,000 albatross chicks and 2,000 adults were killed from the tsunami.
Federal Fish and Wildlife Service officials report that Wisdom, a Laysan albatross first tagged during the 1950’s and estimated to be 60+ years old has survived the tsunami, however.

How close are you to a nuclear power plant? I live near 5! Click the pic, or here.
Wind power helping to keep the lights on in Japan
There’s one piece of good news from Japan: All the wind turbines survived the earthquake and are helping to power some regions of the country.
My latest piece for ADRhub questions Japanese suicide culture and the possible complicity of western media.

Meet Namazu, the Earthshaker. He’s a giant catfish that lives under Japan. When he’s feeling antagonistic, he flips his tail to shake the earth, intentionally reeking havoc on those above.
Above, a Japanese wood-block print showing a giant mythic catfish that causes earthquakes. The horizontally outstretched catfish divides the picture in two parts, in the upper part there are rich merchants, in the lower part mourning people who have lost everything by the earthquake. The aftermath of the earthquake is depicted as possibility to redistribute the wealth; rich people have to divide their wealth with the poor to restore the general “cosmic” balance.

Namazu is one of many mythological creatures who lives in between worlds with fellow monsters and gods. One such god, Kashima, exclusively has the power to hold down the powerful fish. Kashima does this by positioning a sword or a large stone on top of Namazu’s head. Kashima pushes down on the weapon, keeping the fish in steady control. Sometimes, though, Kashima gets tired and loosens his grip - and that’s when the great catfish Namazu flops around causing earthquakes.
Above, the god Kashima immobilizes a guilty Namazu with help of a capstone. Kashima demonstrates his superior power to a several obedient, smaller catfishes who represent earthquakes of the past. His actions show the severe punishment for their ill behavior (click here to read more on Kashima’s great punishments).
During the 18th century, the Namazu replaced the mythological dragons of early Japanese folklore, which previously were to blame for earthquakes. Gradually, Namazu became associated with retributive disasters as a method to punish human greed. Earthquakes, therefore, served as a sort of balancing event, where harmony amongst people was restored by a re-distribution of wealth from the greedy rich (unaffected by disaster) to the impoverished poor who suffered most.
