Using concrete balls to stop a mud volcano. Are they nuts? (Couldn't resist).
Photo in the News: Concrete Balls to Help Plug "Mud Volcano": "February 27, 2007—Indonesian officials have begun dropping concrete balls into a devastating upwelling of mud in a novel but controversial plan to plug up the disaster.
On Monday engineers on the island of Java successfully released the first 16 of the balls into the 'mud volcano,' which has left more than 11,000 homeless, ruined miles of countryside, and killed at least 13 since it began erupting nine months ago.
Over the next few weeks the team plans to drop a total of 1,500 concrete spheres, weighing up to 90 pounds (40 kilograms) each, in an attempt to stanch the flow of mud."
