The resulting flood waters caused a wave, 10 kilometers (6.2 mi) wide and 3–7 meters (9.8–23.0 ft) high in Suiping (遂平), to rush onto the plains below at nearly 50 kilometers per hour (31 mph), almost wiping out an area 55 kilometers (34 mi) long and 15 kilometers (9.3 mi) wide, and creating temporary lakes as large as 12,000 square kilometers (4,600 sq mi).
