How to deploy SmartSolo IGU-16HR 3C in the field – and why it matters.

Proper burial ensures high-quality data. Here's the simple workflow:
Dig a hole – slightly larger than the node
Plant the node – "N" arrow pointing North, bubble leveled
Refill & compact – ensures tight coupling with the earth
Power on – tap near the LED
Scan – wait for green LED (GPS locked), then record deployment via SmartSolo App
Bury – cover with soil (

🔎 Case Study: Dense Array Shear-Wave Splitting Analysis in Shiba

📍 A research team deployed SmartSolo three-component dense arrays in the seismically active Shiba region, recording 359 local events for shear-wave splitting analysis.

📝 Results show a dominant NW-SE fast-wave polarization direction, consistent with surface GPS and deep anisotropy data, suggesting coupled crustal deformation. The average delay time of 3.83 ms/km indicates elevated upper-crustal anisotropy near fault intersections.

⛰️ This study demonstrates that dense arrays combined with shear-wave splitting analysis effectively resolve detailed crustal anisotropy in complex tectonic settings.

🏙️ SmartSolo nodal seismographs for civil defense structure detection

📝 A known air-raid shelter (~2m wide, long extension) was surveyed using microtremor lines deployed perpendicular to its orientation. Both linear and three-circle circular arrays produced consistent results, with clear anomalies matching the shelter's actual location. The shelter appeared as a low-velocity anomaly, with slightly higher apparent shear-wave velocity from the linear array than from the circular array.

Karst detection for a metro project using microtremor surveying with IGU-BD3C-5 seismic nodal system

✅ High consistency with borehole results
✅ Fills geological information gaps between boreholes
✅ Enables precise cavity localization and scale prediction prior to shield tunneling through karst areas

Various array configurations were deployed. Results matched well with later borehole verification.
