iTem pressure sensors deployed for the Sayarim calibration experiment, Israel
22 January 2011
iTem-prs series of infrasonic sensors recorded the 100 tons TNT equivalent explosion performed in January 2011 at the Sayarim Military District (Israel) for calibration of infrasonic arrays. The pressure wave traveled for thousands of km to the east being recorded by arrays in Mongolia.
The iTem infrasonic sensors were deployed and operated by the Geophysical Institute of Israele (GII) at short range from the source (3 and 6 km), and recorded peak pressure of >900 Pa. The broad frequency response and short response time of the instruments perfectly characterized the N-shape of the pressure wave radiated by the explosion.
