Listening to earthquakes

Here is a link to some very interesting work where seismic signals from earthquakes are processed to allow them to be audible. Although they are no longer at the correct frequency content, the human ear when listening to seismic "sounds" is capable of detecting patterns that cannot be discerned by the human eye when looking at wiggle traces on seismograms.

We've moved!

 

I am happy to announce that our office has moved into different digs! Cannot call it a 'new' space because the building is 100 years old. We are in a Craftsman House in the center of Danville, Indiana.

New address:

52 W Broadway Street, Danville, Indiana 46122

Visualization fail

Every atlas you ever see shows water as blue and ice as white. But that is not so in this graphic which appeared in the WSJ. True, a legend is presented which makes this technically "OK" but it does not pass muster in terms of communication between scientists and the public.
