Melting Glacier Reveals Ancient Tree Stumps

Melting glaciers in Western Canada are revealing tree stumps up to 7,000 years old where the region's rivers of ice have retreated to a historic minimum, a geologist said today.

Johannes Koch of The College of Wooster in Ohio found the fresh-looking, intact tree stumps beside retreating glaciers in Garibaldi Provincial Park, about 40 miles (60 kilometers) north of Vancouver, British Columbia.

Radiocarbon dating of the wood from the stumps revealed the wood was far from fresh - some of it dated back to within a few thousand years of the end of the last ice age.

"The stumps were in very good condition, sometimes with bark preserved," said Koch, who conducted the work as part of his doctoral thesis at Simon Fraser University in Burnaby, British Columbia. Koch will present his results on Oct. 31 at the Geological Society of America annual meeting in Denver.

Experts link earthquakes to volcanic activity

Experts say the tectonic quakes that recently struck Java and Sumatra might be responsible for triggering increased activities at several volcanoes on both islands.

A seismologist from the Bandung Institute of Technology (ITB), Nanang T. Puspito, said the tectonic quakes that occurred along the West Sumatra and southern Java coasts over the past week have likely increased activity in a number of volcanoes.

Nanang said plate movements below the earth's mantle could increase the pressure of the upper magma pocket of a volcano and trigger an eruption followed by volcanic quakes.
