Metallica Concert Causes Earthquake in Virginia

During a Metallica concert in Virginia, a crowd of 60,000 people jumped so energetically to 'Enter Sandman' that a seismograph recorded an earthquake. Scientists called it the 'Metallica Quake' - the tremor's magnitude was small (less than 1.0), but the instruments detected it. The concert took place at Virginia Tech Stadium, where 'Enter Sandman' has been used as the anthem of the local football team Hokies for 25 years.
