Mt St. Helens Update: Mt St. Helens has a heart beat!
Developed from over 10 years of seismic research - A major release of new
technology able to reliably detect earthquake precursors from up to a
distance of 1000 kilometers. A Command Center monitors telemetry data from
regional sensors and is able to accurately triangulate large earthquakes
hours in advance. Command centers will be able to alert citizens with
enough warning such that loss of life and property may be mitigated.
