Tonight's Must-See

"Nova: Volcano's Deadly Warning," 8 p.m., PBS. When scientists held a conference in Colombia in 1993 two methods of judging the likelihood that a volcano would erupt brought opposite results. Stanley Williams said the Galeras volcano in Colombia was safe; Bernard Chouet said it could blow at any moment. Williams led a field trip into Galeras, which promptly erupted and killed six scientists. Now Chouet's method, involving seismic patterns, is getting new attention. Two years ago, it led to the evacuation of 30,000 people in Mexico hours before a volcano blew.
