Il Sismografo Umano is an Italian website devoted to an individual researcher’s approach to anticipating earthquakes through bodily sensations, which the site calls “C” signals. It presents daily forecasts for Italy and neighboring countries, as well as predictions for the wider Mediterranean region, based on signals the researcher says were recorded seven days earlier. Posts list perceived precursors and use charts and a color scale, from green for low expected seismicity to violet for very high, to communicate estimated activity.

The site also explains how its author interprets continuous or linked signals, including as possible indications of earthquake swarms or volcanic events, and provides a guide to reading the forecasts. Its archive includes dated reports and references to areas and volcanoes such as Etna, the Phlegraean Fields, and Vesuvius. Visitors can browse notes, signal records, and verification pages, follow the site on Facebook, contact the author, and leave comments.

The website also invites voluntary donations to support the research
