Book Description

This publication summarizes data for earthquakes that occurred in the 50 states and Puerto Rico during 1986.
















Cascadia's Fault


Book Description

A thrillingly rendered, yet “level–headed” look at the Cascadia Subduction Zone and the devastating natural disasters it promises (Booklist) There is a crack in the earth's crust that runs roughly 31 miles offshore, approximately 683 miles from Northern California up through Vancouver Island off the coast of British Columbia. The Cascadia Subduction Zone has generated massive earthquakes over and over again throughout geologic time—at least thirty–six major events in the last 10,000 years. This fault generates a monster earthquake about every 500 years. And the monster is due to return at any time. It could happen 200 years from now, or it could be tonight. The Cascadia Subduction Zone is virtually identical to the offshore fault that wrecked Sumatra in 2004. It will generate the same earthquake we saw in Sumatra, at magnitude nine or higher, sending crippling shockwaves across a far wider area than any California quake. Slamming into Sacramento, Portland, Seattle, Victoria, and Vancouver, it will send tidal waves to the shores of Australia, New Zealand, and Japan, damaging the economies of the Pacific Rim countries and their trading partners for years to come. In light of recent massive quakes in Haiti, Chile, and Mexico, Cascadia's Fault not only tells the story of this potentially devastating earthquake and the tsunamis it will spawn, it also warns us about an impending crisis almost unprecedented in modern history.




Tsunami!


Book Description

On April 1, 1946, shortly after sunrise, the town of Hilo on the island of Hawai'i was devastated by a series of giant waves. Traveling 2,300 miles from the Aleutian Islands in less than five hours, the waves struck without warning and claimed 159 lives. Fourteen years later, on May 22, 1960, a massive earthquake occurred off of the coast of Chile. The earthquake generated giant waves that sped across the Pacific at 442 miles per hour, reaching Hilo in just fifteen hours. The first wave to hit the town was a modest four feet higher than normal, the second nine feet. Before the third wave could arrive, a tidal phenomenon known as a bore smashed into the Hilo bayfront, with thirty-five foot waves that wrenched buildings off their foundations. That day several city blocks were swept clean of all structures and 61 people died. The first edition of Tsunami!, published in 1988, provided readers with a complete examination of the tsunami phenomenon in Hawai'i. This second edition adds many eyewitness accounts of the tsunamis of 1946 and 1960 and expands its coverage to include major tsunamis in the Mediterranean and off the coasts of Japan, Chile, Indonesia, Fiji, Alaska, California, Newfoundland, and the Caribbean, as well as the 1998 devastation in Papua New Guinea. Dramatic photographs and accounts of experiencing a tsunami firsthand are placed within the framework of the how and why of tsunamis, our scientific understanding of these phenomena, and the current status of the Tsunami Warning System, which is widely used to forecast and measure tsunamis and prepare coastal areas for potentially deadly tsunami strikes.
