DENVER (AP) _ Scientists say the
United States' ability to rapidly respond
to major earthquakes in cities is hindered
by an antiquated network of seismic
instruments.

In contrast, a new digital seismic network
in Taiwan alerted officials to the scope
of its magnitude 7.2 earthquake on
September 21 while the ground was still shaking.

Geologists met in Denver Tuesday for the annual
convention of the Geological Society of America said
Southern California is beginning to install digital
monitoring equipment along some of the most notorious
quake-prone faults that crisscross the region's underbelly.

The upgrade was prompted by the Northridge earthquake
in 1994 that killed 57 people and caused more than $20
billion in damage.

But similar monitors are not yet being installed around San
Francisco, where geologists predict a 70 percent chance
of a major earthquake occurring within the next 30 years.

Currently, most of the country is monitored by arrays of
mechanical monitors that read a variety of seismic waves
generated by earthquakes. The information is relayed to
computers for analysis, but the digital systems use
computerized sensors that are faster and more accurate.

Scientists said communities typically wait until after a
natural disaster _ what they describe as the "teaching
moment" _ to make improvements.

"If it wasn't for the Northridge earthquake, Los Angeles
probably wouldn't have any of the technology in place,"
said Mary Lou Zoback, chief scientist of the Western
Earthquake Hazards Team for the U.S. Geological
Survey.

Congress is considering authorizing $170 million to install
a digital network in quake-prone cities across the United
States, including the Pacific Northwest and the Midwest.

The measure has been approved by the House of
Representatives. Even if it wins Senate support, the entire
network would not be in place for another five years or
more, scientists said.

Following the 1995 earthquake in Kobe, Japan that killed
6,000 and caused $100 billion in damage, Japan and
Taiwan installed dense arrays of digital seismic monitors
in their countries.

The monitors cannot prevent damage by themselves, but
provide public safety officials with a nearly-instant reports
of where an earthquake is most severe, or if less-severe
shaking is occurring in an unstable area prone of
landslides.
