New England and nearby areas in the United States and Canada have a long and storied history of earthquakes that goes back to the times of the earliest exploration and settlement of the region by Europeans. This may come as a surprise to the many people living in the region today who have never felt a local earthquake. Nevertheless, not only is it true, but there is every reason to believe that earthquakes, including some damaging earthquakes, will strike New England in the future. In fact, in the 1960s Boston, Massachusetts was given the same seismic hazard rating as Los Angeles, California because both had experienced strong earthquakes in their historic pasts. Since then seismologists have learned much about the rates at which earthquakes occur throughout the country and about the effects of the earthquakes when they occur. Today, we know that the probability of damaging earthquake shaking in Boston is about twenty-five times less than in Los Angeles. Even so, the threat of earthquakes in Boston, throughout New England, and in adjacent regions is one that cannot be ignored. From the 1638 so-called “Pilgrim’s Earthquake” to anticipating what the future may hold, John E. Ebel introduces you to the surprising history of earthquakes in the northeast corridor.
Millions of years ago, the North American continent was dragged over the world's largest continental hotspot, a huge column of hot and molten rock rising from the Earth's interior that traced a 50-mile wide, 500-mile-long path northeastward across Idaho. Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forces stretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith and Siegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in full color--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.
Characteristics of Hawaiian Volcanoes establishes a benchmark for the currrent understanding of volcanism in Hawaii, and the articles herein build upon the elegant and pioneering work of Dutton, Jagger, Steams, and many other USGS and academic scientists. Each chapter synthesizes the lessons learned about a specific aspect of volcanism in Hawaii, based largely o continuous observation of eruptive activity and on systematic research into volcanic and earthquake processes during HVO's first 100 years.

The first effective seismographs were built between 1879 and 1890. In 1885, E. S. Holden, an astronomer and then president of the University of California, instigated the purchase of the best available instruments of the time "to keep a register of all earthquake shocks in order to be able to control the positions of astronomical instruments." These seismographs were installed two years later at Lick Observatory on Mt. Hamilton and at the Berkeley campus of the University. Over the years those stations have been upgraded and joined by other seismographic stations administered at Berkeley, to become the oldest continuously operating stations in the Western Hemisphere. The first hundred years of the Seismographic Stations of the University of California at Berkeley, years in which seismology has often assumed an unforeseen role in issues of societal and political importance, ended in 1987. To celebrate the centennial a distinguished group of fellows, staff, and friends of the Stations met on the Berkeley campus in May 1987. The papers they presented are gathered in this book, a distillation of the current state of the art in observatory seismology. Ranging through subjects of past, present, and future seismological interest, they provide a benchmark reference for years to come. The first effective seismographs were built between 1879 and 1890.
