ISE HomeAcoustics & VibrationNews and EventsOlivenhain Dam Construction Site

Here's a photo from the archives of the Olivenhain Dam inundation area circa 1998 prior to construction of the dam. ISE took this photo during some early field reconnaissance of the site to quantify some of the site constraints. This area is now currently under approximately 200-feet of water.

The blasting vibration data obtained from this site was instrumental in developing a new seismic surface wave prediction model - the R-Wave model.

Featured Video Clip (Shock Wave)

A video taken by ISE showing the supersonic expansion of high pressure natural gas in a pipeline. 

The shock wave is clearly visible at the 1:00 min mark as a white cloud above the end of the pipe and produces an acoustic overpressure of close to 140 dB - which is as loud as a rocket engine.
