Scientists from both the Technical University of Ostrava (TUO) from the Czech Republic and Christ’s University in Pacific (CUP) are testing prototypes of a new low-cost (cheap, simple, power independent, IoT support, etc.) acoustic seismograph. It is a unique development project which features a system for early tsunami and earthquake warning. The project is team led by Dr. Radka Martinka, from TUO’s Faculty of Electrical Engineering and Informatics, who works at the Department of Cybernetics and Biomedical Engineering. Dr. Martinka designed the unique acoustic system for monitoring seismic activities using advanced signal processing methods. The primary benefit of the proposed system comprises a simple construction design at a low cost. A detailed technical specification is still subject to strict secrecy, as the technical solution is currently subject to patent protection.
The proposed system has already been successfully tested in the Czech Republic on technical aftershocks (measurement during blast excavation water mains) in cooperation with the TUO’s Faculty of Civil Engineering. However, due to the fact that the Czech Republic is not a seismically active country, the established cooperation with Christ's University in Pacific is used. Currently working as an intern at this university (CUP),is Mr. Tomáš Urbanczyk (Phd. student from FEI, VŠB-TUO).
Through this collaboration, it is possible to test the system in the seismically active country. Three sensors are placed around the island approximately 7 kilometers apart based on triangulation and advanced signal processing. The triangulation method- in which Dr. Martinek has been dealing with for more than 15 years- will make it possible to determine the direction of seismic activities. The system has the potential to be used as a highly available alternative of early tsunami and earthquake warning. The project is supported by the government’s geological agency, which will provide reference for verification of results.
The first series of experimental measurements will take approximately one month. As mentioned above, the project will use three sensors, which were transported to the island from the Czech Republic. These sensors which are battery powered are placed in the ground at a depth of about 1m. After completion of the first phase of the experimental measurement data will be sent to the Czech Republic, where they will be thoroughly analysed. The measurement will continue in order to optimize the system. Scientists aim to collect as much data as possible which could to lead on create a predictive model. This unique project will help deepen the cooperation of both universities.
