Connect with us at the European Geosciences Union (EGU) General Assembly 2019 in Vienna, Austria on 7-12 April 2019.  We will be presenting on the use of our intelligent Distributed Acoustic Sensor (iDAS™)  for various geophysical applications, such as monitoring volcanic activity and seismicity.

Silixa’s distributed acoustic sensors enable the realization of new applications, where the fiber optic cable can be deployed readily as a dense, wide-aperture acoustic phase-array in novel configurations. With the benefit of high spatial and temporal sampling, Distributed Acoustic Sensing (DAS) has the potential to revolutionise seismological data acquisition on multiple scales across the Earth, even in remote and urban areas, utilising existing fiber-optic infrastructures.

Silixa’s iDAS™ (intelligent Distributed Acoustic Sensor) has been tested as a new tool for monitoring volcanic activity.  iDAS was used to record strain rate signals along a 1.3 km-long fibre optic cable deployed in the Etna summit area. The system recorded the strain rate induced by volcanic sources with 2 m spatial resolution at a sampling frequency of 1 kHz.

To learn about the details of this and several other projects please join us at the event.

 

PRESENTATIONS:
