Officials say New Mexico wildfire has burned nearly 60 homes

ALBUQUERQUE - Firefighters worked in cooler, calmer weather Saturday to clear lines around a blaze that has burned nearly 60 homes and more than 20 square miles in the mountains of central New Mexico.

Authorities were able to confirm Saturday that 50 homes burned Wednesday in a fire caused by humans in the Manzano Mountains, southeast of Albuquerque, said Linda Peters, a fire information officer. Nine homes had burned earlier.


Oxygen-poor ocean zones are growing

Linked to global warming, these areas of the Pacific and Atlantic cannot sustain most marine life, a new study warns.

Oxygen-starved waters are expanding in the Pacific and Atlantic as ocean temperatures increase with global warming, threatening fisheries and other marine life, a study published today concludes.

Most of these zones remain hundreds of feet below the surface, but they are beginning to spill onto the relatively shallow continental shelf off the coast of California and are nearing the surface off Peru, driving away fish from commercially important fishing grounds, researchers have found.

Quakes confuse experts, send kids under their desks

Quakes aren't uncommon there, but analysts just do not know what has caused 344 of them in the area in the past week, the strongest of which was magnitude 4.7.

On shaky ground: UH Prof finds geological faults threaten Houston, US

After finding more than 300 surface faults in Harris County, a University of Houston geologist now has information that could be vitally useful to the region's builders and city planners.

This information - the most accurate and comprehensive of its kind - was discovered by Shuhab Khan, assistant professor of geology, and Richard Engelkemeir, a geology Ph.D. student, using advanced radar-like laser technology. Although geologists have long known of the existence of faults in Southeast Texas, only recently have UH researchers produced a comprehensive map pinpointing the locations of the faults. A Houston-area map showing active surface faults is available here.

While the ground moving beneath Houstonians feet is not felt at the magnitude of recent earthquakes in San Antonio and Illinois, this shaky ground could mean trouble for buildings, roads and pipelines located on one of these hundreds of faults traversing the region's surface.
