Friday Rock Blogging: Keiiti Aki Memorial Edition

caldera of Piton de la Fournaise I’ve been trying this morning to think of a pretty way to illustrate the concept of seismic moment, in tribute to Keiiti Aki, who died last week at the age of 75. Measurements of the energy released by an earthquake are not, as a rule, photogenic. Seismic tomography – another place where we stand on Dr. Aki’s shoulders – is somewhat better, and perhaps this afternoon I’ll find some interesting examples.

Meanwhile, you can’t beat a good volcano for eye candy. Dr. Aki died while working on La RĂ©union, a volcanic island in the Indian Ocean. Like Hawaii, RĂ©union lies atop a “hot spot” of volcanic activity, and Piton de la Fournaise is one of the most active volcanoes in the world. During Indian Ocean daylight hours, check out the webcam.

    Cats, Dogs, Spiders and ? every Friday. We’ll post links to sites that have Friday (plus or minus a few days) photos of their chosen animals as I see them (photoshops at our discretion and humans only in supporting roles). Leave a comment or trackback…
