Earthquakes are difficult to predict. One minute, everything is normal. The next, the ground rumbles enough to rattle dishes in the cupboard or shakes so violently that buildings collapse. There's an earthquake somewhere on earth every day. Big quakes can topple buildings, crumble homes, and threaten the lives of thousands of people. With dramatic images and first-hand survivor stories plus the latest facts and figures this book takes you up close with some of the world's biggest earthquake disasters.
Reveals how 10 undersea mountain ranges and valleys came to be, how and why it has changed over the span of geologic time, and its contributions to the environment.
Fifty years ago, no one could explain mountains. Arguments about their origin were spirited, to say the least. Progressive scientists were ridiculed for their ideas. Most geologists thought the Earth was shrinking. Contracting like a hot ball of iron, shrinking and exposing ridges that became mountains. Others were quite sure the planet was expanding. Growth widened sea basins and raised mountains. There was yet another idea, the theory that the world's crust was broken into big plates that jostled around, drifting until they collided and jarred mountains into existence. That idea was invariably dismissed as pseudo-science. Or "utter damned rot" as one prominent scientist said. But the doubtful theory of plate tectonics prevailed. Mountains, earthquakes, ancient ice ages, even veins of gold and fields of oil are now seen as the offspring of moving tectonic plates. Just half a century ago, most geologists sternly rejected the idea of drifting continents. But a few intrepid champions of plate tectonics dared to differ. The Mountain Mystery tells their story.
(Black and white edition) Slowly, the tectonic plates are moving. Somewhere deep beneath your feet, the rock inside the Earth are squeezing. Someday they might suddenly break and slip, sending waves of energy through the rock, shaking the ground, and knocking over buildings. Scientists and engineers work together to figure out which areas are at risk of earthquakes, to build buildings that will not fall down, and to design special warning systems. If you understand how earthquakes work, you can be prepared, too. All of this is real science, written at a level that kids can read and understand. At the end of the book, you will find a self-quiz to test your new knowledge and fun hands-on activities that build on the science. Judith Hubbard is a geology professor with a Ph.D. from Harvard University and a B.S. from Caltech - and also two young children. She started the In Depth Science series with the goal of making college-level science accessible to kids as young as eight years old.
Argues that the rapid climate change will provoke geophysical events, such as earthquakes, tsunamis, and volcanic eruptions.
Eruptions. Explosions. Shock waves. Tsunamis. The almighty explosion that destroyed the volcano island of Krakatoa was followed by an immense tsunami that killed more than thirty thousand people. The effects of the waves were felt as far away as France, and bodies were washed up in Zanzibar. Today, one hundred and twenty-five years after the volcano erupted in one of the greatest catastrophes the world has ever known, the name Krakatoa is still synonymous with disaster. In this illustrated account based on Simon Winchester's bestselling Krakatoa, the colossal explosion is brought to vivid life. From the ominous warnings leading up to the eruption to the wave of killings it provoked, here is an engaging and insightful look at what happened on the day the world exploded.
In the first half of the twentieth century, when seismology was still in in its infancy, renowned geologist Bailey Willis faced off with fellow high-profile scientist Robert T. Hill in a debate with life-or-death consequences for the millions of people migrating west. Their conflict centered on a consequential question: Is southern California earthquake country? These entwined biographies of Hill and Willis offer a lively, accessible account of the ways that politics and financial interests influenced the development of earthquake science. During this period of debate, severe quakes in Santa Barbara (1925) and Long Beach (1933) caused scores of deaths and a significant amount of damage, offering turning points for scientific knowledge and mainstreaming the idea of earthquake safety. The Great Quake Debate sheds light on enduring questions surrounding the environmental hazards of our dynamic planet. What challenges face scientists bearing bad news in the public arena? How do we balance risk and the need to sustain communities and cities? And how well has California come to grips with its many faults?
