000006536 520__ $$aSmartSolo® seismic nodal sensors have recently been successfully introduced into seismology. Their lightweight and modal setup, reduced costs and user-friendly installation make them suitable for environmental and urban seismology, near-surface geophysics, paleoseismology, and Quaternary geological research. In this contribution, we explore the performance of IGU-16 1C, IGU-16HR 3C and IGU-BD3C-5 SmartSolo sensors in various case studies in the fields of: - Shallow geothermal research, where H/V spectral ratio analyses of ambient noise records by tripod nodes allowed improving bedrock depth models in urban settings (Brussels, BE). We showcase spiked and tripod setups to study characteristics of the Cambrian bedrock that is of interest for shallow geothermal energy usage; - Quaternary research, where thickness changes of Quaternary terraces of the Weser river (Hamelin, GER) were mapped using 163 node positions installed in cross-profiles and arrays. Their array performance can be compared to a 6C seismometer record; - Array seismology, where classic arrays and active shots along linear arrays were used for site characterization of the Belgian seismic network; - Paleoseismology, where H/V profiling above suspected Quaternary faults brought an understanding how fundamental resonance frequency in foot- and hanging-wall across faults can be completely different depending on changing seismic velocities in geological layers. - Environmental seismology, where nodes, installed as gates on Alpine ski-slopes, easily recorded moving skiers and snow thickness; - Glacial seismology, where nodes installed on Icelandic glaciers are capable of deducing glacial thickness and subglacial hydraulic processes; - Outreach, where nodes installed in a linear array recorded an 800-people crowd jumping during a science festival, which allowed simulating a similar ground motion as a ML 1.5 earthquake; In these case studies, we apply different active and passive ambient noise analysis techniques for velocity inversion and subsurface characterization.
