The Jordan Rift Valley, stretching from the Red Sea to Lebanon, was ripped open millions of years ago by vast forces within the earth. This geological object has also been a part of human history ever since early humans used it as a path in their journey out of Africa. And for a quarter of a century it has been part of the biography of Israeli writer Haim Watzman. In the autumn of 2004, as his country was riven by a fierce debate over its borders, Watzman took a two-week journey up the valley. Along the way he met scientists who try to understand the rift through the evidence lying on its surface--an archaeologist who reconstructs the fallen altars of a long-forgotten people, a zoologist whose study of bird societies has produced a theory of why organisms cooperate, and a geologist who thinks that the valley will some day be an ocean. He encountered people whose life and work on the shores of the Dead Sea and Jordan River have led them to dream of paradise and to seem to build Gardens of Eden on earth--a booster for a chemical factory, the director of a tourist site, and an aging socialist farmer who curates a museum of idols. And he discovered that the geography’s instability is mirrored in the volatility of the tales that people tell about the Sea of Galilee. As an observant Jew who has written extensively about science and scholarship, Watzman tries to understand the valley in all its complexity--its physical facts, its role in human history and his own life, and the myths it has engendered. He realizes that human beings can never see the rift in isolation. "It is the stories that men and women have told to explain what they see and what they do as a result that create the rift as we see it,” he writes. "As hard as we try to comprehend the landscape itself, it is humanity that we find. Watzman’s poetic evocation of the scientific and the human is a unique chronicle of a quest for knowledge.

In this investigation, we are primarily concerned with modeling fluid flow through vertical cracks that were created for the purpose of extracting heat from hot, dry rock masses. The basic equation for the two-dimensional problem of fluid flow through a crack is presented and an approximate solution is found. The basic equation is a non-linear, Cauchy-singular integro-differential equation. Moderately simple formulae for the crack opening displacement and the effective pressure difference between the crack tips are derived. The results are valid for arbitrary vertical cracks, provided that the fluid injection and removal points are not placed too close to the crack tips. (A more complete treatment of this problem is given by us in a paper to appear in the Journal of Geophysical Research.) There are two corrections that can be made to our results. One of these is for the influence of the earth's surface. Another correction takes into account the force in the vertical direction produced at the crack walls by the fluid pressure because the crack walls are not vertical when the crack is filled with fluid. It can be shown (Weertman and Chang, Ref. 6) that both of these corrections are negligibly small. We conclude from this analysis that the crack profile and stress intensity factors of any large vertical fluid-filled crack for heat extraction purposes will not be changed appreciably when fluid is forced to flow through the crack at physically practical velocities. 6 refs.

The international bestselling author of The Professor and the Madman and Krakatoa vividly brings to life the 1906San Francisco Earthquake that leveled a city symbolic of America's relentless western expansion. Simon Winchester has also fashioned an enthralling and informative informative look at the tumultuous subterranean world that produces earthquakes, the planet's most sudden and destructive force. In the early morning hours of April 18, 1906, San Francisco and a string of towns to its north-northwest and the south-southeast were overcome by an enormous shaking that was compounded by the violent shocks of an earthquake, registering 8.25 on the Richter scale. The quake resulted from a rupture in a part of the San Andreas fault, which lies underneath the earth's surface along the northern coast of California. Lasting little more than a minute, the earthquake wrecked 490 blocks, toppled a total of 25,000 buildings, broke open gas mains, cut off electric power lines throughout the Bay area, and effectively destroyed the gold rush capital that had stood there for a half century. Perhaps more significant than the tremors and rumbling, which affected a swatch of California more than 200 miles long, were the fires that took over the city for three days, leaving chaos and horror in its wake. The human tragedy included the deaths of upwards of 700 people, with more than 250,000 left homeless. It was perhaps the worst natural disaster in the history of the United States. Simon Winchester brings his inimitable storytelling abilities -- as well as his unique understanding of geology -- to this extraordinary event, exploring not only what happened in northern California in 1906 but what we have learned since about the geological underpinnings that caused the earthquake in the first place. But his achievement is even greater: he positions the quake's significance along the earth's geological timeline and shows the effect it had on the rest of twentieth-century California and American history. A Crack in the Edge of the World is the definitive account of the San Francisco earthquake. It is also a fascinating exploration of a legendary event that changed the way we look at the planet on which we live.

A burgeoning new city is built on the dreams of the American gold rush. It is also built upon a landscape that has been stretching, sliding and breaking apart for millennia. In 1906 the dreams of this city came crashing down beneath the rippling wave of a horrifying earthquake that turned roads into great rippling rivers, that set buildings ablaze for days on end, that made homes collapse upon themselves. Simon Winchester's breathtaking story delves deep beneath the surface of the earth and explains to us why the world moves as it does; and breaks apart with such devastating results. At the same time he never lets us forget the human story: what happened in this new, seemingly blessed city on the 18th April 1906. As he vividly portrays the lives of the people who suffered and survived the devastation he also tells a universal story: the hubris of man as he ignores the warnings of nature and how we respond and try to understand the world around us. Compelling, moving and enlightening, Simon Winchester brings to light the world beneath our feet and through the story of this one terrifying event one hundred years ago, begins to make sense of our world now.

There are many Earth-fill dams in Japan, which are mostly used for irrigation use. Most of these dams in Japan were constructed by experience over 100 years ago. There are so many irrigation dams, which suffered earthquake damage in the past. Due to the damages, the cracks at the crest in the dam-axis direction have been reported in many cases. For the rock-fill dam recently constructed, the crack on the crest in the dam-axis direction has also been found in the case of a large earthquake. The mechanism of such a crack has not been discussed well. In this study, to clarify the mechanism of a crack in the dam-axis direction, a centrifugal loading test was applied to the dam with a 50 G gravity field. As a result, the critical level of strain was observed at the crest of the model, and it was found that the horizontal displacement at the upper part of the dam was excessive. It can be concluded from the study that the seismic cracks in the dam-axis direction occurred due to the excessive tensile stress, which was not considered in the design process.

Please note: This is a companion version & not the original book. Sample Book Insights: #1 The earthquake in Ecuador in 1906 was the most powerful ever recorded by the machines of man. It destroyed the island port of Tumaco, and killed as many as 2,000 people. #2 There were several large earthquakes in the Caribbean in the 1970s, and they did not kill anyone. But they did trigger a burst of smaller earthquakes, which went on for two or three weeks. The island of St Lucia was designated an earthquake-prone territory. #3 The eruption of Mount Vesuvius in 1906 was the most severe in Europe for 300 years. The villages of Bosco Trecase, San Giuseppe, Ottajano, Poggiomarino, and Somma were all covered in several feet of ash, and some had to be hastily abandoned. #4 The most active year of the twentieth century was 1906, which was characterized by a series of earthquakes in major cities. The year was also the most seismically dangerous of the century.

When a repairman accidentally discovers a parallel universe, everyone sees it as an opportunity, whether as a way to ease Earth's overcrowding, set up a personal kingdom, or hide an inconvenient mistress. But when a civilization is found already living there, the people on this side of the crack are sent scrambling to discover their motives. Will these parallel humans come in peace, or are they just as corrupt and ill-intentioned as the people of this world?
