One of my favorite things is taking photos of geologic features. In 12 years of doing that and putting them online here, I've learned a few tricks and tips . This photo illustrates one of the best: get there during the morning or evening "golden hour" for the best light. Most of the other tips in th ...

At the last meeting of my local geological society , they announced that the deadline for our three scholarships , one undergraduate and two graduate, is being extended to December 15 to collect more candidates. This money is meant for research in or near northern California (I guess that means al ...

Last night I attended a presentation on the rock-physics based theory of earthquake precursors (the p-hole theory), and things are moving along nicely. Funders including the World Bank and institutions like the new SUSEL underground lab in South Dakota are supporting research projects. I confess to ...

No, this isn't about a mysterious cosmic visitor that will cause the world to end in 2013. It's about Lake Kivu in Africa, a large rift-valley lake that straddles the Rwanda-Congo border. It is the world's third known erupting lake, after deadly lakes Nyos and Monoun in Cameroon which produced deadl ...

For the first 35 years of its existence as a National Monument, one of the major attractions of the Petrified Forest was Eagle Nest Rock in Jasper Forest. As seen below in an undated National Park Service photo. Eagle Nest Rock was a erosional pillar of sandstone in the Jasper Forest bed of the Sons ...

The geologic time scale was developed during the 1800s based on fossils (biostratigraphy). At that time it was thought that life began about 545 million years ago (when the first clearly visible fossils turned up), and the time from then to now was named Phanaerozoic. The name derives from the Gree ...

These photos come from the Earthlearningidea about the porosity of rocks - 'The space within' . Pupil learning outcomes: Pupils can: - test the porosity of a model in the classroom; - work out the percentage pore space; - explain why some rocks are porous; - apply their knowledge of rock porosity to ...

According to Norwegian scientist Erik Lindeburgh the North Sea could “store about 500 billion tons of carbon dioxide, enough to cover the European Union’s emissions for 300 years.” As reported by Bloomberg.com , Lindburgh sees a dramatic expansion of the Norwegian carbon storage industry in th ...

Back from Iowa, time for some volcano news. Look for the answers to your questions for Dr. Boris Behncke to get posted later this week. (And thanks for all the comments and kind words in the Open Thread . I'll start thinking about how to implement a lot of these in the next few weeks). Undated ph ...
