Campi Flegrei Volcano, developed by an independent volcanologist, is an Android app that allows users to stay updated on the shallow volcanic earthquakes at Campi Flegrei volcano in Campania, Italy. With the risk of eruption slowly increasing since 1950, this app provides valuable information for the more than 600,000 people living in the area.

The app retrieves earthquake data from the Vesuvius Observatory of Italy's National Institute of Geophysics and Volcanology (INGV) in near real-time. It then creates time-series graphs that display trends in earthquake frequency, magnitude, and depth. Users can also view interactive maps that show the epicenters of the earthquakes, along with maps of the official hazard zones and their own location if they are in the area.

Campi Flegrei Volcano is designed to provide easy access to important volcanological data, making it ideal for both residents and visitors who want to monitor any significant changes that might affect the eruption risk of Campi Flegrei. Residents, in particular, will appreciate the app's ability to quickly provide details of any earthquakes that they might feel.
