This book tells the history of Christian missionary encounters with non-Christians, as British and American missionaries spread out from Delhi into the heartland of Punjaba part of the world where there were no Christians at all until the advent of British imperial rule in the early 19th century."
Elizabeth Mancke presents a comparative history arguing that differences in the political cultures of Canada and the United States have their origins in changes in the governance of the British Empire in the late seventeenth and early eighteenth centuries.

Releveling and other geophysical data for the Imperial Valley of southern California suggest the northern section of the Imperial-Brawley fault system, which includes the Mesquite Basin and Brawley Seismic Zone, is much younger than the 4 to 5 million year age of the valley itself. A minimum age of 3000 years is calculated for the northern segment of the Imperial fault from correlations between surface topography and geodetically observed seismic/interseismic vertical movements. Calculations of a maximum age of 80,000 years is based upon displacements in the crystalline basement along the Imperial fault, inferred from seismic refraction surveys. This young age supports recent interpretations of heat flow measurements, which also suggest that the current patterns of seismicity and faults in the Imperial Valley are not long lived. The current fault geometry and basement morphology suggest northwestward growth of the Imperial fault and migration of the Brawley Seismic Zone. It is suggested that this migration is a manifestation of the propagation of the Gulf of California rift system into the North American continent.

The Fault Lines of Empire is a fascinating comparative study of two communities in the early modern British Empire--one in Massachusetts, the other in Nova Scotia. Elizabeth Mancke focuses on these two locations to examine how British attempts at reforming their empire impacted the development of divergent political customs in the United States and Canada.
We conducted a paleoseismic study on the northern Imperial fault at the Dogwood site in Mesquite Basin, southern California, to extend the record of late Holocene surface ruptures in order to better understand the behavior of this plate boundary strike-slip fault. New trench exposures have revealed evidence for up to 17 events in the past 1300 years, yielding an average recurrence interval of 80 years, and the large coefficient of variation (0.844) suggests the fault ruptures in a non-episodic manner. We tested the hypothesis of a connection between lake and earthquake cycles; however, our data indicate that the connection is either very weak or nonexistent as many of the ruptures occurred during dry periods between lakes. On the other hand, we found a strong correlation between the earthquake chronologies in the southern San Andreas fault and the rupture history on the northern Imperial fault, suggesting surface rupture at the southernmost portion of San Andreas fault may have triggered surface slip on the northern Imperial fault, or visa versa.
The destructive force of earthquakes has stimulated human inquiry since ancient times, yet the scientific study of earthquakes is a surprisingly recent endeavor. Instrumental recordings of earthquakes were not made until the second half of the 19th century, and the primary mechanism for generating seismic waves was not identified until the beginning of the 20th century. From this recent start, a range of laboratory, field, and theoretical investigations have developed into a vigorous new discipline: the science of earthquakes. As a basic science, it provides a comprehensive understanding of earthquake behavior and related phenomena in the Earth and other terrestrial planets. As an applied science, it provides a knowledge base of great practical value for a global society whose infrastructure is built on the Earth's active crust. This book describes the growth and origins of earthquake science and identifies research and data collection efforts that will strengthen the scientific and social contributions of this exciting new discipline.
