Liotta and Piochi, Fifty Years of Hydrochemical Data Links Groundwater to Bradyseism at Ca

Three datasets contain hydrochemical measurements from the Campi Flegrei volcanic caldera in Italy. The data includes historical records from deep wells and shallow waters collected over fifty years, compiled by author Monica Piochi. The repository was last updated on April 30, 2026.

Use Cases

• Correlating groundwater chemistry changes with seismic activity based on the fifty-year time series mentioned in the description.
• Mapping the spatial distribution of fluid sources based on the provided site coordinates and Google Earth kmz file.
• Analyzing the evolution of brine and condensate compositions from deep wells over time.
• Homogenizing historical hydrochemical records from various references for comparative analysis.

Strengths

• Covers a fifty-year time span of hydrochemical observations.
• Includes data from both deep wells and shallow water sources.
• Provides geospatial coordinates for sampling sites in a Google Earth kmz file.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file sizes are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific study area and historical collection.
