Sea-based X-band radar (SBX) in port at Vigor Shipyards in Seattle, June 12, 2011. The SBX is a self-propelled mobile radar station designed to transit the Pacific Ocean, tracking the trajectory of ballistic missiles.
SBX has been accused by some of being a mobile version of, or complement to, the U.S. Navy’s Alaska-based High Frequency Active Auroral Research Program (HAARP) which – itself – has been vaguely connected to the idea of artificially generated earthquakes. SBX has been in port since May 11 for routine maintenance, during which time only one earthquake of magnitude 6.5 has occurred, according to the U.S. Geological Survey. An average of seven earthquakes of magnitude 6.5 occurred each month in the preceding part of 2011.
