TefraNet is the new App that the National Institute of Geophysics and Volcanology (INGV) has developed in the field of volcanic monitoring. Fit to device most commonly used laptops (smarthphones and tablets), TefraNet wants to actively involve citizens in areas exposed to the risk of falling tephra, i.e. ashes, lapilli and bombs produced by the most intense explosive activities, through the collection of information in real time.
TefraNet, which already has hundreds of registered users, has known an important test bench during the current Etna eruptive crisis characterized by a sequence of lava fountains, providing excellent results in terms of public response with reports sent by citizens also residing in areas rather distant from the volcano. This allowed INGV researchers to observe in real-time the fallout of tephra in the various Sicilian areas involved, as well as to have a view of the eruptive column from various angles, data in turn useful for studying the ongoing eruption in real time.
The App was created as part of the award project “Ash-RESILIENCE – A research infrastructure for volcanic ash hazard assessment to aviation and communities living near Italian active volcanoes”, funded in 2015 by the MIUR and aimed at creating tools capable of mitigating the effects of the fall of the products of explosive volcanic activity in the two main Italian metropolitan areas with active volcanoes within their territory, namely Catania and Naples.
Since 1998 Etna has been affected by over 200 paroxysmal events, characterized by strong Strombolian activity and lava fountains from the summit craters, which have generated eruptive columns up to 10 km high above the volcano followed by tephra falls in the surrounding areas.
The emission of ash into the atmosphere and its dispersion on the ground also have important implications for civil protection: the constant surveillance of the volcano and the study of its deposits are, in fact, fundamental for the development and validation of simulation models of the propagation of tephra in the atmosphere and their subsequent fall back to the ground, with the aim of mitigating as much as possible the risks for the populations residing in the most exposed locations.
The metropolitan areas of Catania and Naples are densely populated. In fact, there are, respectively, almost one million inhabitants and over three million inhabitants. People who mostly live on the slopes of Etna, Vesuvius and Campi Flegrei. Furthermore, within their territories they host two very busy airports, that of Catania Fontanarossa and Naples Capodichino, considering, moreover, that the military base of Sigonella, a well-known NATO garrison, is located in the Catania area. In areas with these characteristics, therefore, the emission of pyroclastic products into the atmosphere and their fallout on the ground can considerably increase the risks associated with the road network as well as with ordinary airport operations.
To reduce and 'control' these risks, thanks to the TefraNet App, citizens can now participate in monitoring in real-time of Etna, signaling and sharing in real time – during the eruption – important information on the fallout of ash, lapilli and volcanic bombs on the ground. The data, including geo-referenced images, observations and GPS locations, are stored in a geodatabase within the App and can be viewed by 'browsing' among the reports through a search by date or by event.
The next goal, in addition to the implementation of the App for monitoring the Neapolitan area, will be to create an English version of TefraNet. In the future, in fact, the App could also be adapted to volcanoes present in other regions of Italy and the world where the dispersion of ash into the atmosphere represents a problem for everyday life, thus providing useful information to resident populations on the fall of tephra on the ground.

TefraNet, INGV launches an App for real-time monitoring of volcanic ash emissions
A new App for iOS and Android devices allows citizens residing in active volcanic areas to report in real-time the ash fallout during eruptions
TefraNet is the new App that the National Institute of Geophysics and Volcanology (INGV) has developed in the field of volcanic monitoring. Suitable for the most commonly used portable devices (smartphones and tablets), TefraNet seeks to actively involve the citizens of the areas exposed to the risk of tephra fallout, ie ash, lapilli and bombs produced by the most intense explosive activities, by collecting information in real-time.
TefraNet, which already has hundreds of registered users, has been put to the test during the current eruptive crisis of Etna characterized by a sequence of lava fountains. It has provided excellent results in terms of public response with reports sent by citizens also residing in fairly distant areas from the volcano. This allowed INGV researchers to observe the tephra fallout in real-time in the various Sicilian areas concerned, as well as to have a view of the eruptive column from various points, in order to study the ongoing eruption in real-time.
The App was developed as part of the Project “Ash-RESILIENCE - A research infrastructure for volcanic ash hazard assessment to aviation and communities living near Italian active volcanoes”, funded in 2015 by MIUR. The project aimed at creating tools capable of mitigating the effects of the fall of explosive volcanic activity's products in the two Italian metropolitan areas with active volcanoes within their territory, Catania and Naples.

The injection of ash into the atmosphere and its dispersal on the ground also have important implications for civil protection reasons: the constant surveillance of the volcano and the study of its tephra deposits are, in fact, fundamental for the development and validation of numerical models. These models simulate the propagation of tephra in the atmosphere and their subsequent fallout on the ground, with the aim of mitigating the risks for those living in the most exposed locations as much as possible.
The metropolitan areas of Catania and Naples are densely inhabited, with populations of almost one million and over three million, respectively, the people living mainly on the slopes of Etna, Vesuvius and in the Campi Flegrei. In addition, these territories have two very busy airports, namely Catania Fontanarossa and Naples Capodichino, while the NATO military base of Sigonella is located in the Catania area too. In areas with these characteristics, the emission of pyroclastic products into the atmosphere and their fallout on the ground can therefore significantly increase the risks associated with traffic and ordinary airport operations.
To mitigate and 'control' these risks, thanks to the TefraNet App, citizens can now participate in real-time monitoring of Etna, reporting and sharing - during the eruption - important information on the ash fallout on the ground. The acquired data, including geo-referenced images, observations and GPS locations, are stored in a geodatabase within the App and can be viewed by 'browsing' the reports through a search by date or by event.
The next goal, in addition to implementing the App for monitoring the Neapolitan area, will be to create a version of TefraNet in English. In the future, the App can also be adapted to volcanoes in other regions of Italy and around the world where the dispersal of ash into the atmosphere represents a problem for everyday life, thus providing useful information to the resident populations on tephra falls on the ground .
