TROMINO - Tromino - Reactive Tromograph for Geology by

TROMINO is an ideal solution in Engineering Geology for seismic site effect assessment, seismic microzonation, Vs30 estimates, passive seismic stratigraphy, bedrock mapping. Supporting geologists, geophysicists and geotechnical engineers in their daily activities. TROMINO was specifically conceived and designed for the dynamic characterization. Designed in 2002, TROMINO ® is the first all-in-one system for the dynamic characterization of subsoils and structures and for vibration monitoring. TROMINO ® is continuously developed to include the latest electronic improvements, while pursuing MoHo's philosophy of creating only ultraportable and user-friendly instruments, to make the geophysical prospection a sheer entertainment

The Tromino BLU is the new, updated replacement for the ENGY - a small, lightweight, 3-channel, all-in-one seismograph specifically designed for the dynamic characterization of subsoils with the highest accuracy and the lowest effort.This very adaptable device has applications for both geology and engineering. The BLU model is capable of both passive and active seismic acquisition The TROMINO® seismometers can also be used for active seismic refraction, reflection and surface wave surveying. Resource Potentials are the exclusive Australian representatives for the TROMINO® and other near surface geophysical equipment developed by MoHo s.r.l. For sales, rentals, trade ins, processing, modelling and interpretation. Four Model TEP-3C Tromino seismometers were used for the HVSR investigation. The general procedure for collecting the HVSR data included the following steps: (1) select a site off of pavement and infrastructure, andclear of soft debris as needed; (2) orient seismometer to magnetic north an A number of portable passive seismometers are available on the market. The Bardon Hill Quarry survey was conducted using a Tromino instrument (moho.world/tromino/) - a small, broadband, three-component seismometer that utilizes the Horizontal-to-Vertical Spectral Ratio (HVSR) method.

The Tromino seismometers are self-contained, lightweight, portable and very simple to use. The HVSR method of analysis allows the user to quickly estimate the thickness of softer sediment cover over hard basement rocks ranging from 0 to 500m. This method has many applications for mineral exploration, and it may become a standard survey tool to. seismometer incorporating a compact 3-component electrodynamic sensor (velocimeter) with an operating frequency of between 0.1 Hz and 1,024 Hz, above which, anelastic absorption resulting from rock internal friction causes strong attenuation (Castellaro et al., 2005). One advantage of the Tromino is the efficiency with which data can be collected Tromino seismometers are small, lightweight, fully self-contained, easy to use, two units can leap-frog during surveying to collect 40 stations per day per field operator, data processing to be carried out by specially trained geoscientists using Grilla software which comes with the Tromino AVA recordings are obtained in this project using up to 7 three-component Tromino® seismometers placed in a circular array geometry. AVA testing measures the phase velocity of Rayleigh or Love waves across the 2D array (between receiver pairs).

We find UTV based acquisition acquisition most cost effective as far as production goes, but surveys can also be carried out using tracked vehicles, on foot or using helicopters We used a Tromino seismometer installed very close to boreholes to compare HVSR curves with local geology and to validate results. Seismic noise was recorded for 60 min at each site, for a total of 13 sites. Measurements were carried out during the night or very early morning to avoid any artificial transients. In this way, velocity profiles.
