On April 18, 1906, a 7.8-magnitude earthquake shook the San Francisco region, igniting fires that burned half the city. The disaster in all its elements � earthquake, fires, and recovery � profoundly ...disrupted the urban order and challenged San Francisco�s perceived permanence. The crisis temporarily broke down spatial divisions of class and race and highlighted the contested terrain of urban nature in an era of widespread class conflict, simmering ethnic tensions, and controversial reform efforts. From a proposal to expel Chinatown from the city center to a vision of San Francisco paved with concrete in the name of sanitation, the process of reconstruction involved reenvisioning the places of both people and nature. In their zeal to restore their city, San Franciscans downplayed the role of the earthquake and persisted in choosing patterns of development that exacerbated risk. In this close study of the 1906 San Francisco earthquake, Joanna L. Dyl examines the decades leading up to the catastrophic event and the city�s recovery from it. Combining urban environmental history and disaster studies, Seismic City demonstrates how the crisis and subsequent rebuilding reflect the dynamic interplay of natural and human influences that have shaped San Francisco.
Murdering Holiness explores the story of the "Holy Roller" sect led by Franz Creffield, a charismatic, self-styled messiah, in the early years of the 20th century.
Combining the experiences of ordinary people with urban politics and history,Saving San Franciscochallenges the long-lived myth that the 1906 disaster erased social differences as it leveled the ...city. Highlighting new evidence from San Francisco's relief camps, Andrea Rees Davies shows that as policy makers directed various forms of aid to groups and projects that enjoyed high social status before the disaster, the widespread need and dislocation created opportunities for some groups to challenge biased relief policy. Poor and working-class refugees organized successful protests, while Chinatown business leaders and middle-class white women mobilized resources for the less privileged. Ultimately, however, the political and financial elite shaped relief and reconstruction efforts and cemented social differences in San Francisco.
Nostalgia makes claims on us both as individuals and as members of a political community. In this short book, Barbara Cassin provides an eloquent and sophisticated treatment of exile and of desire ...for a homeland, while showing how it has been possible for many to reimagine home in terms of language rather than territory. Moving from Homer's and Virgil's foundational accounts of nostalgia to the exilic writings of Hannah Arendt, Cassin revisits the dangerous implications of nostalgia for land and homeland, thinking them anew through questions of exile and language. Ultimately, Cassin shows how contemporary philosophy opens up the political stakes of rootedness and uprootedness, belonging and foreignness, helping us to reimagine our relations to others in a global and plurilingual world.
This riveting work of social history documents the role the news media played in spurring two murders revolving around Edmund Creffield, a charismatic Holy Roller evangelist who arrived in Corvallis, ...Oregon, in 1903 and quickly enraged the citizenry by defiantly challenging the religious and sexual mores of the time. When ardent female followers began refusing to speak to their nonbelieving husbands, vigilantes tarred and feathered Creffield, eventually forcing him to flee to Seattle.

The 1906/01/31 Ecuador-Colombia earthquake (Mw8.4–8.6), is one of the largest megathrust earthquakes that have occurred at the interface of the Nazca and South-American plates. Recently the source process of the earthquake has been re-examined using historical tsunami waveforms, yielding a slip distribution mainly near to the trench, and a smaller moment magnitude than previous estimations. Previous studies have shown that tsunami data can sufficiently constrain the long wavelength characteristics of slip during an earthquake. However to fully understand strong ground motion generation process during earthquakes in a broadband frequency range, the study of shorter wavelength slip, responsible for high frequency ground motion generation, is also necessary. In this study we use the tsunami-slip model of the 1906 earthquake, as well as comprehensive macro-seismic intensity estimations of the earthquake, to elaborate a broadband-wavelength (BB) source model appropriate for the generation of broadband frequency strong ground motions as well as tsunami modeling. Our results show that a BB slip model of the earthquake is able to satisfactorily reproduce observed intensity values as well as tsunami waveforms. Our BB slip model implies an increase in total moment magnitude to a value up to 8.6 respect to the estimation from tsunami data, which represent the contribution of short wavelength slips to seismic radiation. The methodology developed in this study is suitable to study the generation process of high frequency ground motions during large earthquakes.
One woman's enlightening trek through the natural
histories, cultural stories, and present perils of thirteen
national monuments, from Maine to Hawaii
This land is your land . When it comes to ...national
monuments, the sentiment could hardly be more fraught. Gold Butte
in Nevada, Organ Mountains-Desert Peaks in New Mexico, Katahdin
Woods and Waters in Maine, Cascade-Siskiyou in Oregon and
California: these are among the thirteen natural sites McKenzie
Long visits in This Contested Land , an eye-opening
exploration of the stories these national monuments tell, the
passions they stir, and the controversies surrounding them
today.
Starting amid the fragrant sagebrush and red dirt of Bears Ears
National Monument on the eve of the Trump Administration's decision
to reduce the site by 85 percent, Long climbs sandstone cliffs, is
awed by Ancestral Pueblo cliff dwellings and is intrigued by
4,000-year-old petroglyphs. She hikes through remote pink canyons
recently removed from the boundary of Grand Staircase-Escalante,
skis to a backcountry hut in Maine to view a truly dark night sky,
snorkels in warm Hawaiian waters to plumb the meaning of marine
preserves, volunteers near the most contaminated nuclear site in
the United States, and witnesses firsthand the diverse forms of
devotion evoked by the Rio Grande. In essays both contemplative and
resonant, This Contested Land confronts an unjust past and
imagines a collaborative future that bears witness to these
regions' enduring Indigenous connections.
From hazardous climate change realities to volatile tensions
between economic development and environmental conservation,
practical and philosophical issues arise as Long seeks the
complicated and often overlooked-or suppressed-stories of these
incomparable places. Her journey, mindfully undertaken and movingly
described, emphasizes in clear and urgent terms the unique
significance of, and grave threats to, these contested lands.
The 1906 Colombia–Ecuador earthquake induced both strong seismic motions and a tsunami, the most destructive earthquake in the history of the Colombia–Ecuador subduction zone. The tsunami propagated ...across the Pacific Ocean, and its waveforms were observed at tide gauge stations in countries including Panama, Japan, and the USA. This study conducted slip inverse analysis for the 1906 earthquake using these waveforms. A digital dataset of observed tsunami waveforms at the Naos Island (Panama) and Honolulu (USA) tide gauge stations, where the tsunami was clearly observed, was first produced by consulting documents. Next, the two waveforms were applied in an inverse analysis as the target waveform. The results of this analysis indicated that the moment magnitude of the 1906 earthquake ranged from 8.3 to 8.6. Moreover, the dominant slip occurred in the northern part of the assumed source region near the coast of Colombia, where little significant seismicity has occurred, rather than in the southern part. The results also indicated that the source area, with significant slip, covered a long distance, including the southern, central, and northern parts of the region.
