Geotimes May 2006 Kathryn Hansen	Earthquake Sends Tonga Trembling Strong shaking awoke residents of Tonga when a magnitude-7.9 earthquake rocked the region today. Although Tonga is seismically active, seismologists say that such a large-magnitude event is unusual for the region.
Chemistry World May 2, 2006	Chilling Warnings on Receding Permafrost The annual loss of around 1% of the world's permafrost areas will trigger the release of more greenhouse gases, starting a vicious circle that could make global warming even worse than anticipated, scientists recently warned.
Geotimes May 2006 Avner Vengosh	Rooting Out Radioactive Groundwater Given the continuous degradation of the quality of groundwater in many aquifers worldwide, and the increasing demand for using alternative water resources, the radioactivity factor may be more important than is realized.
Geotimes May 2006 Megan Sever	Yellowstone's Moving Magma New research is suggesting that magma located below the Norris Geyser Basin in Yellowstone National Park periodically rises close to the surface, heating the geothermal field, before diving back down.
Geotimes May 2006 Naomi Lubick	Mixed View on Pesticide Pollution The amount of pesticides in U.S. streams has generally decreased, according to a recent assessment. But urban streams are carrying more and more pesticides, and the number of different chemicals present simultaneously has gone up, raising concerns among some researchers.
Geotimes May 2006 Naomi Lubick	Measuring the Sumatra Quake The motions on the fault that set off the Dec. 26, 2004, earthquake that sent a tsunami across the Indian Ocean continue to puzzle seismologists.
