Well, first of all, I hosed up my registration here by misspelling it.
As a follower of the Eruptions Blog (
http://scienceblogs.com/eruptions/), Dplot was invaluable in my postings there as "Lurking." The recent eruption of Eyjafjallajökull afforded me the opportunity to get a greater grasp on seismology and the functioning underneath the volcano. Many of the other people there enjoyed the data that I was able to present on the spatial representation of quake data.
A couple of plots that I made:
These are quakes under the volcano for the time indicated. I had to scrounge around the Internet to find usable terrain data, and I had to scarf an image of the MOHO, smooth out the annotations and import into Dplot it for the bottom contours. It's effectively the crust/mantle interface.
As another pet project, I grabbed the data on all quakes from 1973 to 2010 for the area 100 miles around the San Andreas from the USGS data server and plotted the latitude vs time. (I had to weed out the data with Excel) This allowed a very nice visualization of quake clusters moving up and down the oceanic/continental crust interface.
Now, whenever I want to visualize data, Dplot is where I turn.
