Analyzing the detection capability of infrasound arrays in Central Europe

摘要

This paper demonstrates the usefulness of continuous infrasound monitoring on regional scales to advance the development of automated source location procedures, as well as provide new insights into quantitative relationships between network detection capabilities and atmospheric specification. To achieve these goals, ground truth events in regions of dense infrasound networks must be considered. The infrasound network of the International Monitoring System (IMS) of the Comprehensive Nuclear-Test Ban Treaty Organization (CTBTO), while currently not fully established, has demonstrated its capability for locating infrasonic sources on a global scale, including meteorites and volcanic eruptions. This paper considers continuous records made by dense networks in Central Europe that are not part of the IMS. It shows the potentiality for future seismo-acoustic monitoring system to be used for discriminating between natural and artificial acoustic sources, and confirms that most of the detected infrasound energy propagates in the ground to stratospheric waveguide.
