The 54.5 million
cubic meter slide traveled those 4.6 km in about 3.5 minutes, with average velocities ranging up to 36 meters per second.

When the volume of a landslide exceeds about 1 million
cubic meters, particles bouncing against each other create variations in pressure within the flow, with bits in some zones experiencing higher pressure than normal and others feeling below average pressure and thus
sliding more readily.
But large
slides (such as the 30 - million -
cubic -
meter flow that occurred in Mesa County, Colorado, and ran more than 4.5 kilometers in 2014, shown) can sometimes travel more than 20 times farther than they fall — and sometimes even, like a fluid, slosh up and over hills.
Scientists» early warnings came true just a month later, when around 700 million
cubic feet (20 million
cubic meters) of rock
slid into the Qinggan River, just two miles (three kilometers) from where it flows into the Yangtze, spawning 65 - foot (20 -
meter) waves that claimed the lives of 14 people.
The new study estimated the
slide came from a volume of rock roughly 55 million
cubic meters (1.9 billion
cubic feet).
The total volume of rock that fell during the
slide was 52 million
cubic meters, they report, enough to cover Central Park with 50 feet of rock and dirt.
