Welcome to the page of my site dedicated to seismology.
Through this page you can visualize the seismograms in real time produced by my seismograph installed in the territory of the province of Crotone.

The choice to publish such a page is due to the awareness of being born and living in a land where the seismic danger is at the highest levels.

In fact, Italy is seismically active, but above all Calabria, and in this specific case the marchesato crotonese , is part of an area of conflict between the African plate and the European plate, it is located on a small platform moving relative to the south-east called "calabro peloritano arc" which is bounded to the north by the tectonic line of Sangineto and to the south by the tectonic line of Taormina.

The marchesato crotonese subjected to the pressure generated by the clash between the plates is currently being lifted, and is bordered by various seismic faults, in fact in past times there were destructive earthquakes among which those of June 1638 (6.9 magnitude) and March 1832 (6.6 magnitude). However, the territory was affected by other destructive seismic events occurring in neighboring areas, such as the seismic sequence of 1783, the earthquake of Rossano in 1836 and the earthquake of Reggio Calabria-Messina in 1908.

From here the compulsory choice to know as much as possible a sneaky enemy, who can attack us at any time without warning and the decision to equip itself with a continuous monitoring tool, in order to grasp the possible precursor signals.

The self-constructed seismograph, consists of a pendulum with a weight at the low end, it, with its micrometric movements generates an electrical signal (through a solenoid immersed in a magnetic field), which appropriately amplified and filtered, is subsequently converted into a digital signal through an A / D converter and processed by a software on a PC.
The software processes the digital signal, generates the seismograms and publishes them on the site at the scheduled frequency.

Another form of monitoring is to process and display the ULF (ultra low frequency) and VLF (very low frequency) signals amplified by an appropriate receiver, also designed and self-built, using a spectrum analyzer. all this in order to grasp possible precursor signals, which manifest themselves with disturbances and impulses, recognizable by an expert eye.
I would like to point out that the precursory signals, according to the various documentation gathered on the web, have never been lacking in the Calabrian earthquakes, and can give notice from a few minutes to a few days before the seismic event occurs.
