Vesuvius and Naples | ![]() |
|
Home Page Naples and vicinity James A. Mallonee There is a major fault zone that runs along the Italian Peninsula. One of the places it is most felt is
near the major city of Naples or Napoli. This area has been settled since ancient times, and has
been devastated since ancient times as well. The town of Naples is litterally built on ring after ring
of craters and caldera left from "extinct" volcano. The former city of Herculanium is "inside" the
modern city of Naples, and Pompei is a few minutes drive up the mountain from the city. The
primary volcanic rock in this area is rhyolite. Chemically the same as granite, rhyolite is the erupted form of the material. Rhyolite volcanos,
according to the various works I have consulted, often erupt very violently. When St. Helens blew
up, it was a rhyolite explosion. These explosions are often accompanied by clouds of volcanic
ash. My acquaintance with this area comes from being stationed 5 hours away. A group of us got
together and went to a camp ground kept in Naples for US and NATO troops. This campground
is in the caldera of one of those "extinct" volcanos. The floor of the caldera is relatively flat,
however the sides are in places quite steep, with masses of rhyolite and pumice in places. On the
rim of the caldera there is a church built exclusively from volcanic rock, there are also the ruins of
several other buildings in the area dating from about the 12th Century. I of course wandered up
and down the length of the place and climbed the sides more than once. Since I am a native of the
State of Washington, and watched Mount St. Helens dump volcanic ash over most of the
Western States as well as blow a couple thousand feet off the top, I did not sleep well the first
night there. The next morning when I smelled the sulfur in the air, was also not at all quieting. After
I reached the rim of the caldera and viewed the rest of Naples, the wonderful ring bay, the little
volcanic islands off the coast a mile or so, the interesting ROUND lakes and holes dotting the
landscape, I was ready to leave. Naples is an interesting place, it is all right to visit, even to vacation there, but thank God I don't
live there. Vesuvius is definitely not an extinct volcano, and considering its past history, it should
not be ignored. |
