Do Earthquakes Telegraph Their Punches? |
Hi All. I thought maybe some of you might be interested in this article. Take Care…Don in creepy town On May 16, 1960, radio astronomer James Warwick of the University of Colorado noted a strange signal recorded at widely separated receivers in Michigan, Colorado, New Mexico and Hawaii. Charts of the signal were similar at all the sites, and astronomers concluded that the source was not extra-terrestrial, but that it must surround the earth or hang over it like a cloud. At any rate, they knew that it was large in extent and not just a point source. Six days later, on May 22, one of the largest earthquakes in recorded history struck Chile. This magnitude 8.9 earthquake was accompanied by fault breakage along a line 540 miles (900 km) long. Twenty-odd years later, the same astronomers who made the original observations have now concluded that the radio signals they recorded in 1960 were likely due to stress-induced microfracturing in quartz-bearing rocks of the Chilean epicentral zone.
