What’s up? The Friday links (19)

Let’s start with some good news: The first two Galileo satellites (Natalia and Thijs) will be launched today from Kourou. It’s a little behind the schedule (6 years) and the entire project has become a little more expensive than previously thought (1,600,000,000 €), but who cares? It will provide 1 m GPS resolution! 1 m!!!

There is one more Archaeopteryx! Really! Soemone who does not want his name to be told handed out the fossil to scientists. After a thoroughly investigation of that great piece of Solnhofen Plattenkalk, the anonymous collector will get back his bird. No, his dinosaur I mean. Ehm, his Archaeopteryx.

Dave Petley reported on a giant landslide in Iceland. It’s expected to have ~1,000,000 m³. See the amazing images, just great.

Maybe everyone has already seen the video of the Cornwall landslide, but it’s just too impressive not to show it again:

I wonder how the lokal tsunami looked like, that certainly had been triggered.

Some interesting studies came out recently:

A new blog was born recently: Earthquake Geology in Greece. This is a page that I will definitely visit regularily. Keep on posting, Alex!

Following the 18 September earthquake in India (M6.9), some environmental earthquake effects have been described in the Environment and Geology blog. Nice surface ruptures. Primary or secondary, what do you think?

There’s a new topographic map of the Earth available. It’s based on Aster data and was published by NASA and Japan. Good news, will be better that SRTM in some places. However, Riccardo pointed out that since Aster is an optical system, there are some problems with clouds. So if your area of interest is covered by clouds, better check the data twice.

USGS has started a new campaign to map buried faults in Colorado by aerial geophysics. I can not work like that here. I need a helicopter! Now!


Have a nice weekend!
