This Giant Inverted Boomerang shuttle coaster has two 196-foot tall vertical lifts at the ends of 1,204 feet of steel track with three inverting elements. Aftershock begins with a backwards ascent up the 19-story lift. As the train reaches the peak its dropped forwards, straight down to reach a top speed of 65 miles-per-hour. The track continues through the station and into a cobra roll double inversion, followed by a vertical loop before ascending the lift at opposite end. The ride then repeats itself, but this time with the train traveling backwards.
