What’s up? The Friday links (51)

I am not entirely sure why the following video was produced, what it is aiming for and if it should be used in geoscience education, but I like it. It very nicely illustrates what a green potato would experience if it was on a cruise ship, from there went down to the seafloor with a yellow submarine, was trapped by a submarine landslide and subducted into the Calabrian Arc and then by using a time machine spit out by Stromboli volcano or so. I always wanted to learn about this.

However, here’s the science behind the movie.

A fascinating landslide in Malaysia

Dave Petley covers a fascinating mass movement event that occurred at an engineered slope in Malaysia. If you thought we had beaten natural forces there, you were obviously wrong.

Aerial images of the 1944 Vesuvius eruption

In 1944, when the US Army had liberated Naples already, Mount Vesuvius had its last big eruption. Here you will find spectacular imagery from USAF personnel showing the ash column.

2012 Volcanic Year in Review

Staying with volcanoes, I can recommend to read Erik Klemetti’s review of volcanic activity worldwide in 2012. From El Hierro to Popocatépetl from Etna to Nevado del Ruiz – here’s a eruption for everyone!

Fossils in 3d

Now this is a nice project – the British Geological Survey made 3D videos of some fascinating fossils in great detail and published the clips on YouTube. Don’t forget your red and blue glasses when watching Proterozigzag crassizigzag and its friends (not joking, that’s the scientific name…)! (HT Louisville fossils and beyond)

Roger Bilham, India and his paper – paleoseismological studies needed

Some days ago I wrote a few words on the issue that Roger Bilham was denied entrance to India, probably because of his seismic hazard statements that Indian officials didn’t like. Now Suvrat Kher from Recent Uplift wrote about the story (and as I noticed, he did before also), and he has read the paper. Three of the conclusions are:

5. Palaeoseismic trenching across the Vijaydurg scarp to establish the absence, or timing and amount of slip of the Vijaydurg Fault.

6. Trench studies of onshore palaeoliquefaction, clastic dikes and buried sand vents in terrestrial low-energy sedimentary environments within 50 km of Jaitapur.

7. A systematic search for palaeotsunami deposits along the western coast of India within 100 km of the Jaitapur site using shoreline and lagoonal deposits, cores and trenching.

Sounds like a to do list for us paleoseismologists.

More mind-blowing cartoon geoscience education

I found this one via the Iceland Geology Blog: The WB Animaniacs dancing around explaining earthquakes in California and jumping and singing while everything is falling apart and into rubble. Judge by yourselves:

History of Geology on the 1908 Messina EQ and Tsunami

David Bressan, who always has great coverage of historic geologic events, with a nice article on the 28 December 1908 Messina earthquake and tsunami that killed tens of thousands of people.


Have a nice weekend!
