.Some photos speak for themselves
Some gestures communicate more than words ever could, like these
clasped hands, which seek comfort in the face of fear of the unknown. The picture was
taken Oct. 8, 2005, when aftershocks were still being felt from the strongest earthquake
ever to strike Kashmir, in northern India. Those clasped hands symbolize terror and
panic; they speak of fragility and helplessness, of endurance in the face of
chaos. Unlike storms and volcanic eruptions, earthquakes are unpredictable, unleashed
within seconds, and without warning. They spread destruction and death, forcing
millions to flee from their homes. The day after the catastrophe revealed a terrifying
scene: debris everywhere, a number of people injured and dead, others wandering
desperately, children crying, and over three million survivors seeking help after losing
everything. Throughout history Earth has been shaken by earthquakes of greater or
lesser violence. These earthquakes have caused great harm. One of the most famous
is the earthquake that rocked San Francisco in 1906. Registering 8.3 on the Richter scale,
the temblor left nearly three thousand dead and was felt as far away as Oregon to the
north, and Los Angeles in southern California. The purpose of this book is to help you
better understand the causes of fractures and the magnitude and
violence of the forces deep within the earth. The full-color, illustrated book you hold in
your hands contains shocking scenes of cities convulsed by earthquakes and
volcanoes, natural phenomena that, in mere seconds, unleash rivers of fire, destroy
buildings, highways and bridges, and gas and water lines and leave entire cities without
electricity or phone service. If fires cannot be put out quickly, the results are even more
devastating. Earthquakes near coast lands can cause tsunamis, waves that spread
across the ocean with the speed of an airplane. A tsunami that reaches a coast can
be more destructive than the earthquake itself. On Dec. 26, 2004, the world
witnessed one of the most impressive natural disasters ever. An undersea quake
with a magnitude of 9 on the Richter scale shook the eastern Indian Ocean, causing
tsunamis that reached the coastal areas of eight Asian nations, causing about 230,000
deaths. The earthquake was the fifth strongest since the invention of the
.seismograph. Satellite images show the region before and after the catastrophe
