On 4 January, 2011 a partial solar eclipse was visible in Central Europe (up to 80% coverage of the sun). Werner Kraus shot some nice photos through a number of filters, but the best picture surely has been made by Thierry Legault from Muscat, Oman – the partial eclipse with the ISS transiting! Incredible.
From this website you can download the Munsell Rock Color Chart as a CorelDraw color palette. Direct download via http://www.dotterweich.net/TipsTricks/Munsell/Munsell.cpl. Really useful for drawing geological sketches!
The Pacific Tsunami Warning Center and the West Coast and Alaska Tsunami Warning Center are always worth a visit. Whenever a strong earthquake occurs in the Pacific region, they provide the data and evaluate whether a tsunami is likely or not. For Japan check out the Japan Meteorological Agency.
The National Earthquake Hazards Reduction Program not only provides a library, but also informs on news, grants and contracts. A nice page with lots of infos.
Geology.com reported on a NASA press release: Earthquake Ground Deformation – Remote sensing and GPS studies of the Magnitude 7.2 El Mayor-Cucapha Earthquake. It’s amazing to see what data the remote sensing techniques can provide. This tool will surely enhance the understanding of earthquake mechanisms. The use of satellite and airborne data in paleoseismological studies is increasing – don’t miss the future and check out this great video: LiDAR-Illuminating Earthquake Hazards
A geological map of the world is provided by OneGeology. You can view different layers for different regions and personalize your maps. Looks like the project is stuck a little, but the data provide a nice overview. Hopefully they will continue adding data.
Have a nice weekend!
