The website muda.mi.ingv.it (MUDA, Multiparametric Database) shows as the main element of the home page an interactive map of the national territory in the areas where to date multiparametric stations consisting of seismo-accelerometric, hydrogeochemical, geochemical and meteorological instrumentation are installed.
Data are acquired in real time (with the exception of radon data in local logging and downloaded periodically), stored in the MUDA database and published online in 24-hour delay.
On the map, all multi-parameter stations are represented with blue triangles that can be clicked to access individual station pages. The map has pop-up thematic layers (top-right menu) including seismic hazard values of the national territory reported in the MPS04 map (https://zonesismiche.mi.ingv.it/), seismogenic zones and active faults inferred from the Database of Individual Seismogenic Sources (DISS) database (https://diss.ingv.it), recent (https://terremoti.ingv.it/) and historical (https://emidius.mi.ingv.it/CPTI15-DBMI15/) seismicity bulletins, and location of seismic stations of the National Seismic Network (RSN, https://terremoti.ingv.it/instruments/network/IV) of INGV.
Basemap presents by default the view using OpenStreetMap (https://www.openstreetmap.org/), with the option of OpenTopoMap (https://opentopomap.org/).
Clicking on each of the blue triangles in the map opens a pop-up containing the main information about the multi-parameter site, specifically the coordinates of the site, the instrumentation installed, and the link leading to the specific station page where the technical characteristics of each of the instruments installed are shown.
Above the map is a horizontal menu for navigating the site, while at the bottom of the page is technical information regarding cookies, privacy, site map, as well as the data use disclaimer.
The link “Project” in the horizontal menu on the home page describes in summary form how the MUDA idea was born, the philosophy of the project, the type of stations analysed and analysable, and the type of data archived and published.
The link “Data visualization and download" in the horizontal menu on the home page opens the page dedicated to viewing and downloading data at each station.
The user can select the time series to view backward in time (i.e., 1 day, 7 days, 15 days, 30 days) from the selected date. For time series longer than 30 days make request via email [javascript protected email address].
The "Station" drop-down menu allows to select the station to be displayed. Once the station and period are selected, the time series of all available data automatically appears. They are, from top to bottom:
hydrogeochemical data from sensor-diver in the well (water temperature, electrical conductivity and height of the water column above the sensor), weather data (air temperature and rainfall), seismometric data sampled on 5-minute windows (RMS mean square, maximum velocity value in cm/s, mean value of Fourier spectrum amplitude, Fourier spectrum values for frequency bands between 0.5 Hz and 20 Hz), Radon gas concentration in the atmosphere and CO2 flux at the ground.
All interactive graphs can be zoomed in using the left mouse button and present the ability to select individual features using pop-up layers. In each graph, in the upper right part, it is possible to view the individual image in full screen and download the image in pdf (Portable Document Format), png (Portable Network Graphic), jpeg (Joint Photographic Experts Group), svg (Scalable Vector Graphics) formats. In addition, also from the same menu it is also possible to directly download the graph values in text files in numeric csv (Comma Separated Values) format.
The individual station pages show a detailed map of the site based on OpenStreetMap, and information in tabular form of the main technical characteristics of the seismic, hydrogeochemical, meteorological, radon and CO2 flux stations.
Specifically, the seismic-accelerometer stations are part of the National Seismic Network (RSN) (http://terremoti.ingv.it/instruments/network/IV) and from the Dynamic Planet Multiparametric Northern Italy Seismic Network (http://terremoti.ingv.it/instruments/network/ZO), both managed by INGV (www.ingv.it).
Hydrogeochemical, geochemical and meteorological stations are part of the PDnet network and were installed as part of the INGV Dynamic Planet 2020-2022 project (https://progetti.ingv.it/it/pian-din), Task2 (structure of Italy from multidata analysis: Passive/active seismic, magnetometric, magnetotelluric, geoelectric, gravimetric imaging) and of the Pianeta Dinamico GEMME (Integrated Geological, gEophysical and geocheMical approaches for 3D Modeling of complex seismic site Effects) 2023-2025 project. Radon stations are provided by INGV's IRON network (Italian Radon Monitoring Network, https://www.ingv.it/en/monitoring-and-infrastructure/monitoring-networks/ingv-and-its-networks/iron).
The link “Information” in the horizontal menu on the home page leads back to the main institutional and useful websites for the user to have all the information necessary for a proper understanding and interpretation of the results. It also provides some bibliographical references considered representative for the study topic, links to infrastructures contributing to the project, and credits with the list of human resources who contributed to the creation of the database and the MUDA website.
The link “Contact” links to the project mailing list, muda.mi.ingv.it
