The state Conservation Department released four more in a series of seismic hazard maps that have come under fire from legislators seeking to cut state expenses by terminating the program. The maps, showing 60-square-mile areas in the Antelope Valley and other sections of the northeast part of Los Angeles County, bring to 89 the number of maps issued thus far. They show areas where a strong quake could be expected to generate landslides and what are known as liquefaction problems.

As scientists uncover new dangers posed by a fault under densely populated areas of Los Angeles, two programs that protect the public against earthquake hazards could be cut in a Republican push to find more money for closing the state's budget hole.

Officials in the Los Angeles Unified School District are expected today to recommend that unfinished high school buildings on a seismic fault at the Belmont Learning Complex be used for other purposes or sold. Under the new proposal, another set of classroom buildings would rise on the western 12 acres of the 35-acre property and house about 1,500 students, less than half the enrollment previously planned, according to a school board member and other officials.

The Earth is creating a new fault in the mountains southeast of Lake Isabella, U.S. Geological Survey scientists said. It is likely to take thousands or even a million years before becoming a full-fledged fault that could pose a major new earthquake hazard, geophysicist Gerald W. Bawden said. Scientists said this may be the first time in history that an infant fault has been detected in the process of formation.

A group of experts has expressed concern at the Bush administration's proposal to cut in half the appropriations for a national network of 6,000 earthquake monitoring stations, including 1,000 new stations in Southern California. In an attempt to convince Congress of the value of the program and get the installation schedule back on track, the U.S. Geological Survey has set up a briefing for members of Congress and their staffs in Washington on Thursday.

Despite eight years and several hundred thousand dollars spent on study, Southern California remains years away from developing an early warning system for earthquakes, according to quake scientists. In the mid-1990s, many public officials and scientists were optimistic about developing such a system for Southern California as early as 2000. The optimism stemmed from the success of a warning system in Mexico City that gave 50 seconds' notice of a major 1995 temblor 190 miles away in the Pacific.

State geologists released maps this week that for the first time identify six seismic hazard zones in Ventura County and are part of a statewide project to hold all builders accountable to the same engineering standards for earthquake safety. The maps show areas at risk from the secondary effects of earthquakes in Fillmore, Ojai, Oxnard, Piru, Port Hueneme and the Rincon Beach area north of Ventura.

Meeting for the first time since the announced discovery of an earthquake fault below the Belmont Learning Complex, members of the Los Angeles school board Tuesday night hinted that building a smaller high school on a less seismically scarred portion of the site might be the least painful alternative. In a 20-minute discussion, Supt. Roy Romer outlined three options for the troubled property near downtown.

The discovery of a minor fault trace running beneath the Belmont Learning Center site is no surprise to Southern California geologists: The entire region is crisscrossed by hundreds of large and small faults, many of them unidentified. "It's very difficult to go to any part of Southern California and find a piece that doesn't have faults cutting through it," said James Dolan, a geologist at USC. "The question is, is the fault active? Most of them probably aren't."

Los Angeles school officials said Wednesday that they will consider abandoning the half-finished and trouble-ridden Belmont Learning Complex because seismologists belatedly discovered a small earthquake fault running directly beneath two buildings of the high school campus.
