This site is a must mention the Community of Geology Dr. Geol. Dolmetta Angelo, who created the first DOLANG DBS, under DOS, with a portable Zenith in 1984 (seems like yesterday), in fact the first Virtual Seismograph in the world.
Great mind, which continues with innovative technical advice to a host of geologists, most Italians, involved in geophysics.
A very good reference point .
