The main objective of this proposal is to resolve and characterize small scale P- and S-wave velocity anomalies in the upper crust beneath the phonolitic centres of the East Eifel Volcanic Field, where a scientific drilling proposal is suggested (ICDP-EIFEL). The combination of velocity anomalies poses important constraints to understand and interpret the remnant magma reservoirs, and to resolve volumes that have enhanced temperatures. Here, the P-to-S velocity ratio is of particular importance due to its sensitivity to changes in pore fluids. Additionally, a model for the shallow hydrothermal system can be supported, if combined with measurements for CO2 degassing, deformation and seismicity. This objective shall be approached by a local earthquake tomography (LET) in combination with ambient noise waveform and seismicity analysis.
