Eric confirmed to me that this story was true.
Tesla built a small vibratory resonance device that almost brought his lab and all surrounded buildings down in a pile of dust once. The police rushed into his lab only to see him smash the small device with a sledge hammer as it had gotten out of control.
A simply amazing tale that ties Tesla, John W Keely and music all together with seismology. Eric knows the study of earth quakes quite well as his old lab at Landers CA was an earth quake detection station. An awesome confirmed read for all true Tesla Fans. As there is a great deal of misinfo and out right disinfo about Tesla a confirmed story is always good to know.
