Earthquake when ever and where ever you need one, just light up a top fueler on Nitro, they'll nail 3.9 on the richter scale

As those watching took in the excitement of hearing and seeing a Top Fuel dragster in person, Dr. Doug Brittsan, of Brittsan CPT, measured the movement of the earth with a mobile seismograph.

Once the dragster had been shut off, Dr. Brittsan got to work evaluating the data. End results? The movement of the earth created by the Snap-on Tools Top Fuel dragster was equivalent to an astounding 3.9 on the Richter scale.
