Minivibe Truck (IMAGE) University of Nevada, Reno Caption The minivibe truck, using a relatively light 700-pound reaction weight, will stop every 30 feet, set the shaker on the asphalt and vibrate the ground for a few minutes. Hundreds of monitoring sensors connected by cable transmit the soundings to the recording truck. It's a slow process, with the truck creeping less than one mile a day along the river route.
