NEES Liquefaction Experiment Uses HPWREN for Real-Time Data Communications
Extreme ground shaking during earthquakes can dramatically decrease
the stability of saturated soils to the point where the soil becomes
a viscous fluid. This behavior, called liquefaction, can cause
severe damage to buildings and other structures as their foundations
can slide or unevenly settle.

UCSD Optical Fiber Infrasound Sensor Utilizes HPWREN for the Data
Transport from the Piñon Flats Observatory
An Optical Fiber Infrasound Sensor (OFIS), is a revolutionary new
instrument to record atmospheric acoustic waves at frequencies below
that which a human can hear. It functions as a directional microphone
tuned to listen to the whispers in the atmosphere. Recording these
whispers, this instrument will facilitate the investigation and
monitoring of a wide variety of phenomena including meteors,
thunderstorms, atmospheric turbulence, volcanic processes, earthquakes,
surf conditions, and certain human activities.
