The "Integrated Marine and Land Survey Data Acquisition System" is an earthquake exploration system developed by the Earth Science Comprehensive Research Institute, which conducts physical exploration, geological surveys, and measurements. It seamlessly enables earthquake exploration from shallow marine areas to land. 【Seismic Source System】 ■ Shallow Marine Areas - Large air gun source (over 1500 cu.in.) - Small air gun source (up to 480 cu.in.) ■ Land Areas - Large vibroseis source (41,000 lbs) - Medium vibroseis source (15,000 lbs) *For more details, please refer to the catalog or feel free to contact us.

The "Shallow Seismic Reflection Survey for Tunnel (SSRT)" is a technology that uses elastic waves to predict the geology ahead of a tunnel face. It was jointly developed with Fujita Corporation for the purpose of exploring the area in front of the tunnel. Since it is possible to select artificial seismic sources (hydraulic impactors, vibrators, blasting sources) according to the conditions of the tunnel site being excavated, there are no limitations on the applicable tunnels. For example, it can also be implemented in mechanically excavated tunnels that include Tunnel Boring Machines (TBM). 【Features】 - It can be conducted outside the tunnel construction site before excavation. - Exploration is possible in hard rock formations, soft ground, tunnel entrance areas, and low cover sections. - Since exploration behind the tunnel face is also possible, it allows for a more accurate evaluation of forward exploration by comparing it with excavation results.
