The seismic gap hypothesis of earthquake recurrence, threatened by four large and seemingly "premature" quakes in the last two years, appears under closer scrutiny to remain valid. The hypothesis maintains that once an earthquake ruptures a fault, the same region will not rupture again until enough time passes–usually many decades or centuries–for stress to rebuild.…

By a two-to-one margin, members of UCSC’s Academic Senate have approved a proposal that will permit new students–beginning next fall–to accumulate a grade-point average. Under the grading plan, both new and continuing students will also be eligible to request letter grades for all classes, beginning in the fall. Of a total of 276 votes cast…

A national Associated Press article called upon UCSC astronomers Robert Kraft and Michael Bolte for input about a new theory that researchers have overestimated the ages of the oldest stars in the galaxy by several billion years. Kraft, Bolte, and others are taking the theory seriously, but have yet to be convinced. Andy Markovits of…

"Hot spots," the isolated patches of volcanism unrelated to plate tectonics, may spring from surprisingly deep within the planet: the turbulent boundary between earth’s mantle and its core. That conclusion, sure to put scientists on the spot at the AGU meeting, has arisen from intense study of a layer at the base of the mantle…

Standard techniques for measuring metals in groundwater may drastically overestimate their levels, forcing owners of supposedly contaminated sites to "remediate" problems that may not exist. Graduate student Carol Creasey and professor of earth sciences Russell Flegal, both of UCSC, studied the groundwater from two wells at a reportedly contaminated site in central California. A consulting…

The Conference and Summer Housing Office is looking for students to assist with its summer operations. Applications for summer jobs are due by February 7. An informational job mixer will be held on Wednesday, January 22, from 6:30 to 7:30 p.m. in the Porter Fireside Lounge. For more information, call ext. 2611.

Earth scientists gathered in San Francisco the week before Christmas for their largest annual confab, the American Geophysical Union meeting. As usual, UCSC researchers represented themselves well, giving about 60 talks and posters. Short summaries of five talks of interest appear below. For the full text of each article, click on the title. New way…

Hydrogeologists have taken the closest look yet at the intricate cycle of fluids that flow relentlessly beneath the seafloor. That flow, it now appears, is far more forceful than expected. Driven by the heat of the planet’s interior, water courses through pores and cracks under the ocean in earth’s upper crust. The water leaches minerals…

The slow but relentless drippings of calcium-rich water in caves may open a new window on earth’s past climate, thanks to a precise dating technique under development at UCSC. Preserved within the stark beauty of stalactites and stalagmites are two records of changes in the climate of the outside world. One such record is purely…
