Perusing the
USGS page on yesterday's magnitude ~8 earthquake in Samoa, I found a new feature that I had not previously seen on these earthquake data pages: a
cross-section! Check it:
The star gives the location of yesterday's temblor some regional context. This is a super-cool visualization of a subduction zone (in this case, the Pacific Plate subducting beneath the Indo-Australian Plate). I'll be using this image in my upcoming "earthquakes" lecture in Physical Geology. What a beautiful way of visualizing the plunge of a slab of oceanic lithosphere!

I've greatly enjoyed your blog which helps feed my avocational interest in geology (and I've been disappointed that my local community college does not offer anything like your Historical Geology class). After exploring the USGS website and elsewhere without much success, I am hoping you might steer me to a description of how to read a seismicity cross section.
Okay... Try this!
