He is a member of various professional societies' technical committees on lifeline systems and performance in earthquakes. His presentation focuses on lifeline systems and the major issues associated with regional shifts of resources following a catastrophic earthquake.

Some of the major problems associated with resource shifts will be identified and some positive aspects of resource shanog will be discussed. An example of how one might incorporate seismic vulnerability studies into looking at this problem of postearthquake recovery will then be provided.

A major disruption caused by an earthquake in the Midwest wiD likely cause shortages of supplies to the Northeast. This question of economic impact, in fact, is being addressed by the National Center for Earthquake Engineering Research in one of the studies that focuses on oil pipelines i.e., what are some of the socioeconomic impacts of a major disruption of oil supply?

Then finally, similar utilities will generally be regulated by the same agency, and to the extent that regulations and standards play a role in terms of design, construction, or repair of these types of systems, this may help facilitate a recovery effort. There are positive aspects associated with the interregional transfer of resources.

Sanding, casing damage, and pump motor damage all imply that the casing will be damaged and that something needs to be done about the casing to repair that facility. Wellhead damage and connecting piping damage would be things that would affect aboveground components.

If one looks at the spatial distribution of the don aye, it was fairly concentrated on the Marina District in San Francisco, downtown Oakland, the Bay Bridge, the Cypress section of the I-880 freeway, the Embarcadero Freeway, and Santa Cruz. The Cypress structure does not exist any longer.

The data in Figure 5-1 is a composite index number involving six different variables, including real estate, the services sector, the retail sales sector, tourism, trade, and manufacturing, and it remained remarkably flat in the entire period. The tourism sector shows a noticeable effect.

If anything, there was a dip in the unemployment level in November, immediately following the earthquake. This was true throughout much of the region, even in Santa Cruz County, which sustained significant physical damage.

The bridge seems to have become a psychological barrier. The earthquake resulted in a significant decline in the supply of lowcost housing for the poor and for members of various ethnic groups because of the damaging structural impacts in the Oaldand area, the area south of Mission Street in San Francisco, and the Tenderloin District (a region with a large Indochinese refugee population)

But there are certainly major economic impacts within the region, especially at the subregional and neighborhood levels. More attention needs to be paid to some of these issues also because good public policy must look at distributional effects, not just economic aggregate effects.

From page 139... ...
In California we have a very special situation where there really are two major gas suppliers or distribution companies -- PG&E and Southern California Gas. The sort of scenarios in California are really kind of independent events, so a lot of mutual aid resources and so forth can be expected to be to be there.

If a large earthquake occurred closer to that area, the shaking effects would cause significant damage to facilities. Damage may not be so limited as what we saw in this event.
