Utility Performance Panels in the ShakeOut Scenario

چکیده

The ShakeOut Scenario assessed earth-science impacts, physical damage, and socioeconomic impacts of a hypothetical M7.8 southern San Andreas Fault earthquake. Among many detailed studies were special studies of 12 lifelines, 7 of which were performed by panels of employees of the utilities at risk. Panels met for four hours. Panelists were presented with the scenario’s earth science impacts and previously estimated damage to “upstream” lifelines. They then hypothesized a realistic outcome of the earthquake on damage and service restoration, identifying research needs and mitigation options. The panel process worked well: panelists were well qualified and seemed to fairly assess realistic earthquake impacts and restoration, probably more realistically than an outside consultant would have been able to do, thus improving the ShakeOut. Panelists gained insight into lifeline interaction, mutual-aid needs, communication capabilities, and backup supplies. Southern California Edison, for example, enhanced its planning and preparedness for a large Southern California earthquake. [DOI: 10.1193/1.3584121]

Developing a Scenario for Widespread Use: Best Practices, Lessons Learned

The ShakeOut Scenario is probably the most widely known and used earthquake scenario created to date. Much of the credit for its widespread dissemination and application lies with scenario development criteria that focused on the needs and involvement of end users and with a suite of products that tailored communication of the results to varied end users, who ranged from emergency managers to t...

Hope for the Best, Prepare for the Worst: Response of Tall Steel Buildings to the ShakeOut Scenario Earthquake

This work represents an effort to develop one plausible realization of the effects of the scenario event on tall steel moment-frame buildings. We have used the simulated ground motions with three-dimensional nonlinear finite element models of three buildings in the 20-story class to simulate structural responses at 784 analysis sites spaced at approximately 4 km throughout the San Fernando Vall...

The Pre-Producers

Until its sales of a product materialize, a firm is a “pre-producer” in the market for that product. That firm may may be a new start-up, or it may already sell other products. Firms that do not succeed in generating sales eventually become discouraged and move on to other activities. When this fate befalls a lot of firms, as it recently did in several IT-related businesses, the indistry experi...

مطالعۀ اثر رطوبت و دمای محیط بر عملکرد پنل‌های فتوولتائیک

Climatic conditions affect the performance of photovoltaic panels. In this study, the effect of ambient air temperature and relative humidity on the performance parameters of two types of silicon photovoltaic solar panels, including mono-crystalline silicon (mc-Si) and polycrystalline silicon (pc-Si), were studied in the laboratory scale. The experiments were carried out by the performance test...
