Tidal Wave Warning

PORT MORESBY, Papua New Guinea () -- Two volcanoes raged for a third day Wednesday around the devastated port city of Rabaul, and officials warned residents in nearby coastal villages of a new possible danger -- tidal waves.

Despite the dangers, 150 troops were deployed following reports that abandoned homes and businesses had been looted. A small number of people have refused to leave their homes, but more than 30,000 have fled the area.

The National Broadcasting Commission used its shortwave radio service to warn residents to take cover if they noticed a sudden drop in the sea level, an early sign of tidal waves.

Witnesses said huge mushroom clouds of smoke and debris continued to pour high into the sky from the Tavurvur and Vulcan volcanoes, which violently erupted early Monday. Much of the falling ash had combined with rain, turning to a heavy mud mixture.
