Loss Estimations

We update annualized and scenario earthquake loss estimations for California using HAZUS, a loss estimation tool developed by the Federal Emergency Management Agency, and evaluate the effects of changes in input ground motions over the last decade on estimated earthquake losses. Our estimated statewide average earthquake loss to building stock from shaking is approximately $2.8 billion per year, with 32% of it occurring in Los Angeles County and 23% in the San Francisco-Oakland-Fremont metropolitan statistical area. This estimate reflects a 25% to 28% reduction because of changes in input ground motions. Scenario results indicate a 28% to 63% reduction in estimated building economic losses because of changes in input ground motions. Changes in input ground motions are mainly attributed to the use of next generation attenuation relations and, to a lesser extent, to updated earthquake source models and differing approaches for incorporating near-surface site effects.

Wide Acceptance

In the 1970s, Japanese cooks began to appear in the kitchens of nouvelle cuisine chefs in France for further training, with scores more arriving in the next decades. Paul Bocuse, Alain Chapel, Joël Robuchon, and other leading French chefs started visiting Japan to teach, cook, and sample Japanese cuisine, and ten of them eventually opened restaurants there. In the 1980s and 1990s, these chefs' frequent visits to Japan and the steady flow of Japanese stagiaires to French restaurants in Europe and the United States encouraged a series of changes that I am calling the “Japanese turn,” which found chefs at fine-dining establishments in Los Angeles, New York City, and later the San Francisco Bay Area using an ever-widening array of Japanese ingredients, employing Japanese culinary techniques, and adding Japanese dishes to their menus. By the second decade of the twenty-first century, the wide acceptance of not only Japanese ingredients and techniques but also concepts like umami (savory tastiness) and shun (seasonality) suggest that Japanese cuisine is now well known to many American chefs.

The City

In 1871, the city of Chicago was almost entirely destroyed by what became known as The Great Fire. Thirty-five years later, San Francisco lay in smoldering ruins after the catastrophic earthquake of 1906. Or consider the case of the Jerusalem, the greatest site of physical destruction and renewal in history, which, over three millennia, has suffered wars, earthquakes, fires, twenty sieges, eighteen reconstructions, and at least eleven transitions from one religious faith to another. Yet this ancient city has regenerated itself time and again, and still endures. Throughout history, cities have been sacked, burned, torched, bombed, flooded, besieged, and leveled. And yet they almost always rise from the ashes to rebuild. Viewing a wide array of urban disasters in global historical perspective, The Resilient City traces the aftermath of such cataclysms as: --the British invasion of Washington in 1814 --the devastation wrought on Berlin, Warsaw, and Tokyo during World War II --the late-20th century earthquakes that shattered Mexico City and the Chinese city of Tangshan --Los Angeles after the 1992 riots --the Oklahoma City bombing --the destruction of the World Trade Center Revealing how traumatized city-dwellers consistently develop narratives of resilience and how the pragmatic process of urban recovery is always fueled by highly symbolic actions, The Resilient City offers a deeply informative and unsentimental tribute to the dogged persistence of the city, and indeed of the human spirit.

This case is about Aaron Caddel, an entrepreneur, who owned several coffee houses and bakeries in San Francisco and Los Angeles and had to rethink his businesses during the Covid 19 pandemic in early 2020. Aaron pulled the plug on his operations on March18, operated as a grocery store until March 21. With no knowledge of e-commerce but possessing a staff of skilled bakers and a 4,200 square foot warehouse, Aaron believed he could pivot his business and keep his workers employed. His concern was the steps he should take to support a business that would help him keep his workers employed during the pandemic.

Abstract Introduction The COVID-19 pandemic has resulted in societal-level changes to sleep and other behavioral patterns. Objective, longitudinal data would allow for a greater understanding of sleep-related changes at the population level. Methods N= 163,524 deidentified active Fitbit users from 6 major US cities contributed data, representing areas particularly hard-hit by the pandemic (Chicago, Houston, Los Angeles, New York, San Francisco, and Miami). Sleep variables extracted include nightly and weekly mean sleep duration and bedtime, variability (standard deviation) of sleep duration and bedtime, and estimated arousals and sleep stages. Deviation from similar timeframes in 2019 were examined. All analyses were performed in Python. Results These data detail how sleep duration and timing changed longitudinally, stratified by age group and gender, relative to previous years’ data. Overall, 2020 represented a significant departure for all age groups and both men and women (P<0.00001). Mean sleep duration increased in nearly all groups (P<0.00001) by 5-11 minutes, compared to a mean decrease of 5-8 minutes seen over the same period in 2019. Categorically, sleep duration increased for some and decreased for others, but more extended than restricted. Sleep phase shifted later for nearly all groups (p<0.00001). Categorically, bedtime was delayed for some and advanced for others, though more delayed than advanced. Duration and bedtime variability decreased, owing largely to decreased weekday-weekend differences. WASO increased, REM% increased, and Deep% decreased. Additional analyses show stratified, longitudinal changes to sleep duration and timing mean and variability distributions by month, as well as effect sizes and correlations to other outcomes. Conclusion The pandemic was associated with increased sleep duration on average, in contrast to 2019 when sleep decreased. The increase was most profound among younger adults, especially women. The youngest adults also experienced the greatest bedtime delay, in line with extensive school-start-times and chronotype data. When given the opportunity, the difference between weekdays and weekends became smaller, with occupational implications. Sleep staging data showed that slightly extending sleep minimally impacted deep sleep but resulted in a proportional increase in REM. Wakefulness during the night also increased, suggesting increased arousal despite greater sleep duration. Support (if any) This research was supported by Fitbit, Inc.

Travel Time Variability

A methodology and its application to measure total, recurrent, and nonrecurrent (incident related) delay on urban freeways are described. The methodology used data from loop detectors and calculated the average and the probability distribution of delays. Application of the methodology to two real-life freeway corridors in Los Angeles, California, and one in the San Francisco, California, Bay Area, indicated that reliable measurement of congestion also should provide measures of uncertainty in congestion. In the three applications, incident-related delay was found to be 13% to 30% of the total congestion delay during peak periods. The methodology also quantified the congestion impacts on travel time and travel time variability.
