Episode 17 of the podClast concentrates on the 6.3 magnitude earthquake with struck Christchurch on 22nd of February 2011 which has tragically resulted in thousands on injuries and hundreds of deaths. We chat about the seismic setting and the human element of this disaster. Also discussed is the concept of the anthropocene, a proposed new geological epoch, age or chron (whichever it may be).

Christchurch / Canterbury Earthquake

The seismic data of the earthquake can be found at Geo Net and the USGS.

Chris’s post on aftershocks, triggered earthquakes and Christchurch’s future. And his post on possible seismic lensing.

The Australian ABC has interactive ariel shots before and after the earthquake.

Christchurch City Libraries have a brief rundown on historical earthquakes in Christchurch.

The GNS map comparing September’s 7.1 M quake and Tuesday’s 6.3 M quake, centered on Lyttelton.

Dave Frampton’s mother was caught in the collapsed PGG building. Dave tweeted right through the event. You’ll probably want to follow the sequence starting on the 22nd of February 1343, 1416, 1425, 1504, 1510, 1526, 1646, 1658, 1719, 1730, 1735, 1841, 1844, 1847, 1849, 1852, 1940, 23rd February 0620, 0628, 0730, 0850, 1108, 1117, 1256, 1315, 1346, 1348, 1357, 1436, 1445, 1446, 1444, 1510, 1544, 1614, 1649, 1651, 2136, 24th of February 0650, 25th of february 0029, 0831, 1053, 1733, February 26th 1533, 1609.

Help If You Can

Dave and his family were very lucky. Tragically, many other Christchurch families have lost homes, businesses, property and more seriously, been injured and lost loved ones. All the people in Christchurch are in need of help as they recover and New Zealand as a country starts the clean up and rebuilding of our second largest city. If you can spare a little money to help our plucky little nation out, please consider the following avenues for donation;

Firstly there’s The Official New Zealand Government Earthquake Appeal. Here’s a NZ Herald article about the appeal. This will help directly by helping rebuild Christchurch while those who are directly affected are given all the help they need.

The Red Cross in New Zealand is accepting donations. The Red Cross does fantastic work the world over, and has been working tirelessly in Christchurch.

And if you want to get a little entertainment out of your donations, this week all profits from the purchases of Chopper 2, by Dave Frampton (mentioned above) will go towards the quake appeal. You can get Chopper 2 on iPhone, iPad and Mac OS X.

The Anthropocene

The Wikipedia entry on the Anthropocene.

Andrew Alden at About:Geology has a good summary of the debate around the Anthropocene proposal. And details about how the term will appear in National Geographic next month.

You may also want to read up on the Geological Time Scale.

Ole Nielsen talks about the Earthquake in New Zealand – and “Beach Balls”.

In case you’re wondering, no there haven’t been more earthquakes than normal recently.

Geographile has a post with a collection of pictures of damage.

And Cosmic Log talks about why the Christchurch quake in no Haiti.

And for a retrospect, Wikipedia has a list of all >M 6 earthquakes to have been recorded in New Zealand.

Yucca Mountain and Nuclear Waste

You can read about Yucca mountain on the Wikipedia page. And there’s the extensive page on the nuclear waste storage project too.

And Lee Allison talks about Yucca Mountain ‘stalemate’. which refers to the Chicago Tribune article arguing to Keep Yucca Mountain Project Alive.

And there’s an article about France’s nuclear waste storage program, and its problems, at Energy Priorities.

MIS:TIQUE

You can read about the MIS:TIQUE project over at Ian’s blog.

And, of course, Gigapan gets a few mentions too : )

Next Episode

We like to have a new episode of the podClast every fortnight. I will be away in Edinburgh next recording day, however, so episode 14 maybe early, or late. I’ve yet to decide.

This week’s podclast is the Geobloggers in the Pub episode. We talk about the KT boundary, including new research relating to it. Plus we lay into creationism in a pub-style chat fest.

The K-T Boundary and What Caused It

The paper we were discussing is by G. Keller et al. in Journal of the Geological Society, Vol. 166, 2009 [of London]. I can’t find the full name of the paper but I’ll keep looking.

Kim at All My Faults are Stress Related has a post on K-T extinction debates: cranky “skeptics” or reasonable science?

And the press release is available in various mass-media-filtered forms at Time, and the BBC.

Ethan Siegel’s Starts with a Bang has an article called What Wiped Out the Dinosaurs?, which is a superb run-through of the Chicxulub/KT impact. And you may want to read up on the Deccan Traps and how they relate to the KT extinction too. Also of interest, not because it explains the extinction, but because it’s another narrowly thought-out idea (or at least that’s how it’s been presented) is Insect Attack May Have Finished Off Dinosaurs which talks about the research from the book What Bugged the Dinosaurs?.

Creationism

You can look up Answers in Genesis yourself, as I won’t be linking to them, however the Talk.Origins Archive is a great place to look for basic questions and answers regarding the Evolution/Creationism debate.

Extra Note

The fossil of the seal ancestor is called the Pinniped, and information on the find can be found at the BBC and Eureka Alert.

Italian Earthquake

The USGS has the raw details of the M6.3 earthquake.

Chris from Highly Allochthonous discusses the tectonic setting of the quake as well as the foreshocks and aftershocks.

Kim from All My Faults Are Stress Related talks about earthquake predicition, including that made by Iben Browning.

Ole from Olelog also discusses earthquake prediction in L’Aquila Earthquake – Followup.

Andrew from About:Geology calls the prediction irresponsible,  and so does the New York Times.

And the report from the BBC concerning the destruction that occurred is worth a look too.

Mt Redoubt

There’s a good summary of rticles regarding the previous set of eruptions from the podClast episode 10.

This is the picture Ron mentioned of the growing lava dome from the Alaskan Volcano Observatory.

Next Episode – Geoblogger in the Pub

We like to have a new episode of the podClast every fortnight. The next episode, however, will be recorded live at the Geobloggers in the Pub, in London on the afternoon of Saturday the 2nd of May. We’ll be drinking at the Cittie of Yorke, 22 High Holborn, London, WC1V 6BN from 2pm onwards.

Chris –  Highly Allochthonous (@allochthonous)

The Gamburtsevs Mountain Range and Antarctica

The BBC News article “‘Ghost peaks’ mapped under ice” is a nice summary of the story. New Scientist article has additional information in the article “Alpine mountain range revealed beneath Antarctic ice.”

And as always, there’s a little more information at Wikipedia on the GamBurtsevs Mountain Range.

Here’s some information about Lake Vostok.

And you can read about the International Polar Year at Wikipedia.

Extremophile Bacteria at the top of the Andes

Have a read of Science Centric’s Article “Earth’s highest known microbial systems fuelled by volcanic gases.”

NASA’s Kepler Mission

There’s the Wikipedia page on Kepler and the NASA’s official Kepler Mission page too. Plus there’s an example of the mass media misinterpretation from the BBC.

And Venetian resurfacing I was talking about is detailed  in this interview with David Grinspoon “Venus (and Earth) Resurfaced in a Single Catastrophic Event?” and in the paper Catastrophic Resurfacing and Episodic Subduction on Venus from Science Direct. This episodic resurfacing is still up for debate, though, and The Imperial College in London has a counter view.

Exbiology, Panspermia and Planetary Geology

Titan is Saturn’s moon with methane oceans.

Europa is the Jovian moon (beware the obelisk).

You can read about the Dawn Mission at NASA’s official site, or there’s the Wikipedia entry.

My article on Ceres, Dawn and (no) Panspermia (containing information on Ceres, 4-Vesta, the HED meteorites and the Murchison meteorite). And the offending article on The Universe Today.

There’s information about the bacteria on the Moon

Dave’s article on resurrected Eocene yeast and the resulting beer.

The Allan Hills 84001 was the one with the bacteria-looking inclusion in it.

Mars had recent running water and there’s Google Mars to have a look at too.
