The Cascadia Subduction Zone (CSZ) “megathrust” fault is a 1,000 km long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino California. It separates the Juan de Fuca and North America plates. New Juan de Fuca plate is created offshore along the Juan de Fuca ridge. The Juan de Fuca plate moves toward, and eventually is shoved beneath, the continent (North American plate).

Great Subduction Zone earthquakes are the largest earthquakes in the world, and are the only source zones that can produce earthquakes greater than M8.5. The CSZ has produced magnitude 9.0 or greater earthquakes in the past, and undoubtedly will in the future.

In 2009, some geologists predicted a 10% to 14% probability that the Cascadia Subduction Zone will produce an event of magnitude 9.0 or higher in the next 50 years. In 2010, studies suggested that the risk could be as high as 37% for earthquakes of magnitude 8.0 or higher.

AmRRON created the CSRG radio net for this and any other disaster. Our radio operators are top notch using all modes of radio with a focus on digital. We use FLDIGI, FLAMP, FLMSG and WINLINK to pass crucial message traffic.

Our radio net is scheduled for the 1st and 3rd Tuesday of the month at 7:30 PM pacific time all year long on 3.588 USB. The preamble begins using the digital mode Contestia 4/250.
