T3.1 Seismic, Hydroacoustic and Infrasound Technologies and Applications

Oral

Designing an array is one of the main tasks during setup planning. Array configuration depends on the goal of monitoring, which may cover a large variety of purposes including monitoring of the desired area, local seismicity, global teleseismic monitoring, etc. In this study, we developed a method to automatically design an array configuration for regional monitoring purposes by optimizing the...

676. Interlaboratory Comparison on Infrasound Sensors (Results of PTSAVH.A-C1) (O3.1-676)

Dr Dominique Rodrigues (Laboratoire National de Métrologie et d'Essais (LNE))

6/22/23, 4:40 PM

T3.1 Seismic, Hydroacoustic and Infrasound Technologies and Applications

Oral

The Provisional Technical Secretariat (PTS) defined a quality assurance programme for infrasound measurement systems of the International Monitoring System (IMS). This resulted in collaborations with international experts in the field of infrasound, metrology, and quality assurance. An objective is to ensure consistency in measurements and equivalence in data produced across the IMS network....

698. Determination of the Frequency Response of Seismic and Infrasonic International Monitoring System Station Sensors Using an On-Site Calibration Approach (O3.1-698)

Ms Michaela Schwardt (Federal Institute for Geosciences and Natural Resources (BGR))

6/22/23, 4:55 PM

T3.1 Seismic, Hydroacoustic and Infrasound Technologies and Applications

Oral

The development of laboratory calibration methods for seismometers and microbarometers in the low frequency range down to 0.01 Hz provides the possibility of a traceable on-site calibration during operation for field sensors of the International Monitoring System. The laboratory calibrated reference sensors can be installed as transfer standards at the stations co-located to the operational...
