This section describes the impact of seismic monitoring on these three elements of emergency response and recovery, and examines the potential benefits of enhanced monitoring. It is important to keep in mind that both the benefits of seismic monitoring and the examples that are cited in this section currently apply only to the limited region -- essentially urban areas of California -- where state-of-the-art networks are currently in operation and the density of network coverage is sufficient to provide relatively accurate information for emergency response and recovery.

Response readiness -- action associated with development of plans and conducting exercises -- relies on seismic monitoring to describe long-, intermediate-, and short-term earthquake potential, to provide information on earthquake effects, and to estimate the impacts of earthquakes on the community. For areas of high seismic risk, the U.S.

Earthquake swarms in this area or a single moderate-size event (Mw 5) -- if interpreted by scientists as potentially precursory to a large event on the San Andreas Fault -- would trigger activation of plans that require specific actions by the California Governor's Office of Emergency Services (OES)

These actions include taking cover, moving away from hazards, evacuating vulnerable buildings, programming elevators to stop at the next floor and open doors, shutting down computer systems, slowing down or stopping trains, and a range of other possible activities. Although earthquake early-warning systems based on modern digital seismic networks could be implemented in the United States and are being planned as part of future Advanced National Seismic System (ANSS)

. Clearly, there are significant economic benefits in scaling a response to the consequences of an event, including no response for an earthquake that requires none.

Reliable operation of seismic monitoring networks is a critical requirement for providing earthquake information to the emergency management community. Like all lifeline infrastructure, seismic networks are dependent on electric and telecommunication utilities as well as the Internet.

With the development of modern seismic networks -- in combination with the loss estimation capabilities of HAZUS-this process can become more efficient and relatively free of conflict. HAZUS provides the rapid, reasonably accurate, and objective estimate of total dollar losses from an earthquake that is needed for a preliminary damage assessment.

Instead, a zip code-based seismic intensity map, using source data from the Southern California Seismic Network, was used to determine grant eligibility. If an applicant's residence was in one of the 66 zip codes that corresponded to estimated Modified Mercalli intensities of VIII, IX, or X, the applicant was sent a check, reducing the delay between application and receipt of funds from weeks to a few days.

Enhanced seismic monitoring, including the placement of accelerometers in buildings and near infrastructure, expedites the immediate post-earthquake safety evaluation of structures and can be used either to avoid needless evacuations in smaller earthquakes or to expedite evacuations in larger events where the safety of occupants is jeopardized. Although timely information was provided by the California Integrated Seismic Network following the recent Mw 6.5 San Simeon earthquake of December 22, 2003, this information proved to be inadequate for an effective emergency response.

SUMMARY Seismic monitoring and the products that are derived from modern networks -- including ShakeMap and HAZUS -- offer significant benefits for emergency response and recovery. The benefits of enhanced seismic monitoring include rapid and accurate identification of the event, its location and magnitude, the extent of strong ground shaking, and estimates of damage and population impacts.
|
From page 143... ...
Only over the last decade or so have seismic networks, because of significant advances in computing and software, developed capabilities that address the needs of emergency response and recovery. Partnerships between network operators and emergency managers in well-monitored regions are strong, new technologies are being integrated into response and recovery plans, and capabilities are waiting to be proven.
