1 Water molecules have a. 2  because the electrons in each covalent bond between the oxygen and each hydrogen are unequally shared-the electrons are closer to the oxygen. 3  This means that each water molecule has a partial negative charge on the oxygen and partial positive charges on the hydrogens.
The 7.9 magnitude quake, which rattled the area Nov. 3, 2002, has been the subject of research and fascination since. Scientific studies of the quake, whose epicenter was about 90 miles south of Fairbanks, spawned new national standards for building bridges and are providing a deeper understanding of how earthquakes affect frozen ground.
The earthquake was widely felt by Anchorage residents, but the Anchorage and Valdez police departments said they hadn't received any reports of injury or significant damage. The earthquake struck about 1:30 a.m. Alaska time and was centered 53 miles west of Anchor Point in the Kenai Peninsula, which is about 160 miles southwest of Anchorage, according to the U.S. Geological Survey. Vincent Nusunginya, 34, of Kenai said he was at his girlfriend's house when the quake hit.
