Product Description

Product Description

MASW Refraction Reflection Nodal Seismograph Microtremor Survey Land Node Seismograph HVSR Seismic Survey Equipment

The MASW Refraction Reflection Nodal Seismograph is multi-functional geophysical system engineered to deliver high-precision subsurface imaging and site characterization across diverse terrains and applications. By integrating Multichannel Analysis of Surface Waves (MASW), Seismic Refraction/Reflection, Microtremor Surveys, and Horizontal-to-Vertical Spectral Ratio (HVSR) methodologies, this advanced nodal seismograph offers unparalleled versatility for geotechnical, environmental, and exploration projects.

Equipped with autonomous wireless nodes and high-sensitivity sensors, the system efficiently captures both active-source (e.g., hammer strikes, vibroseis) and passive-source (ambient noise) seismic data. Its lightweight, rugged design ensures rapid deployment in urban environments, remote landscapes, or challenging conditions, while real-time processing software generates actionable insights for shear wave velocity (Vs) profiling, bedrock mapping, fault detection, and seismic hazard assessment. Designed for engineers, geophysicists, and researchers, this system bridges the gap between cost-effective field operations and laboratory-grade accuracy.
 

Applications

1. Geotechnical Engineering & Infrastructure Development

• MASW: Measure shear wave velocity (Vs30) for soil stiffness analysis and earthquake-resistant foundation design.

• Refraction/Reflection: Map bedrock depth, identify voids/sinkholes, and assess subsurface stability for roads, bridges, and tunnels.

• Microtremor Surveys: Evaluate ground vibrations and resonance risks in densely built urban areas.

2. Oil, Gas, & Mineral Exploration

• Refraction Seismic: Characterize shallow hydrocarbon reservoirs and stratigraphic traps.

• Nodal Arrays: Conduct high-density 2D/3D surveys for mineral exploration with minimal environmental impact.

3. Environmental & Hazard Mitigation

• HVSR: Assess site-specific seismic hazards, including liquefaction potential and ground motion amplification.

• Passive Seismic Monitoring: Detect groundwater resources, landfill boundaries, and landslide-prone zones using ambient noise.

4. Urban Planning & Construction

• Microtremor Analysis: Monitor vibration impacts from construction activities and infrastructure health (e.g., dams, pipelines).

• MASW/Reflection Integration: Optimize foundation design for high-rise buildings in soft soil regions.

5. Disaster Preparedness & Research

• HVSR & MASW: Map fault lines and liquefaction zones for earthquake risk reduction.

• Academic Studies: Investigate tectonic structures, glacial sediments, or volcanic activity with multi-method seismic data.

6. Renewable Energy Projects

• Bedrock Mapping: Identify optimal locations for wind turbine foundations or geothermal drilling.
