Wednesday Whatzits: Keeping up with Iceland, Etna and Kilauea from space and Central America's geothermal riches
Good morning from a drizzly Ohio!
Been a rather quiet news for much volcano news so far - well, that is beyond the reawakening of Nevado del Ruiz in Colombia. I haven't found much more information beyond my update yesterday, but I'll keep my eyes and ears open.
A few quick bits to tide us over:
A new Iceland Blog: If you haven't already, be sure to check out Jon Frimann's new blog - the aptly titled Iceland Volcano and Earthquake Blog. He has information on every noise the volcanoes of Iceland make. Talk about packed full of all the details of the inflation/deflation, earthquakes and rumors about any potential volcanism on the North Atlantic island nation. Hopefully Jon will continue to grace us with updates over here on Eruptions as well if big things are brewing in Iceland.
Images of Etna and Kilauea: The NASA Earth Observatory posted a couple new images this week. The first is of Mt. Etna in Italy, showing the steaming plumes on the summit region. Our friend Boris Behncke assisted with the annotating of the image. Not a lot to report on Etna since the explosions earlier this fall, but Boris, as always, has posted great images of the area around the volcano. The second has an image of the ocean entry of lava at Kilauea, which is creating a lava delta. You can see both the satellite and a land-based image of the ocean entry - and be sure to check out the post on the delta by Brian Romans over at Clastic Detritus.
Geothermal energy in Central America: The Freakonomics Blog at the New York Times had a very brief post on geothermal energy in Guatemala - specifically tapping the heat generated at Pacaya.Much of Central America is trying its hand with geothermal energy thanks to the high heat flow under much of the region.

China's Chang'e 4 biosphere experiment marks a first for humankind.
- China's Chang'e 4 lunar lander touched down on the far side of the moon on January 3.
- In addition to a lunar rover, the lander carried a biosphere experiment that contains five sets of plants and some insects.
- The experiment is designed to test how astronauts might someday grow plants in space to sustain long-term settlements.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
Arranged marriages and Western romantic practices have more in common than we might think.
In his book In Praise of Love (2009), the French communist philosopher Alain Badiou attacks the notion of 'risk-free love', which he sees written in the commercial language of dating services that promise their customers 'love, without falling in love'.
