The 2004 Indian Ocean tsunami was triggered by a 9. 15 magnitude earthquake (MELTZNER et al. , 2006; CHLIEH et al. , 2007) that occurred at 0:58:53 GMT, 7:58:53 LT (USGS) (t ). The epicenter was located at 3. 3 N, 95. 8 E (Fig. 1) with a focal depth of EQ approximately 30 km. The earthquake was responsible for a sudden fault slip estimated on average from 12–15 m (SYNOLAKIS et al. , 2005; LAY et al. , 2005) to 20 m (FU and SUN, 30 2006). The seismic moment estimate (Mo = 1. 3 5 9 10 dyne-cm), based on the Figure 1 Locations of video recordings, recovered clocks, and reliable eyewitness observations. 1: Coastal plains ?ooded by the tsunami; 2: non-?ooded coastal plains; 3: uplands.

The world's foremost experts write about the dynamics of geophysical processes involved in tsunami generation, propagation, and inundation, along with the statistical and geophysical properties of tsunami recurrence, and their application to tsunami forecasts and warnings.
This title is a comprehensive survey of maritime archaeology as seen through the eyes of nearly fifty scholars at a time when maritime archaeology has established itself as a mature branch of archaeology.
Historians have long asserted that during and after the Hannibalic War, the Roman Republic's need to conscript men for long-term military service helped bring about the demise of Italy's small farms and that the misery of impoverished citizens then became fuel for the social and political conflagrations of the late republic. Nathan Rosenstein challenges this claim, showing how Rome reconciled the needs of war and agriculture throughout the middle republic. The key, Rosenstein argues, lies in recognizing the critical role of family formation. By analyzing models of families' needs for agricultural labor over their life cycles, he shows that families often had a surplus of manpower to meet the demands of military conscription. Did, then, Roman imperialism play any role in the social crisis of the later second century B.C.? Rosenstein argues that Roman warfare had critical demographic consequences that have gone unrecognized by previous historians: heavy military mortality paradoxically helped sustain a dramatic increase in the birthrate, ultimately leading to overpopulation and landlessness.
This book explores the interactions of theories of risk with natural disasters, health crises, and crises in the areas of science and technology. Using organizational frameworks developed exclusively by the author, it provides a series of best practices and lessons related to each of the emergency and crisis situations covered. These lessons will assist students and practitioners, engaged in learning about and reacting to crises, to better respond to them. The mass protests that erupted in China during the spring of 1989 were not confined to Beijing and Shanghai. Cities and towns across the great breadth of China were engulfed by demonstrations, which differed regionally in content and tone: the complaints and protest actions in prosperous Fuijan Province on the south China coast were somewhat different from those in Manchuria or inland Xi'an or the country towns of Hunan. The variety of the reactions is a barometer of the political and economic climate in contemporary China. In this book, Western China specialists who were on the spot that spring describe and analyze the upsurges of protest that erupted around them.
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 172 .The Kamchatka Peninsula and contiguous North Pacific Rim is among the most active regions in the world. Kamchatka itself contains 29 active volcanoes, 4 now in a state of semi-continuous eruption, and I has experienced 14 magnitude 7 or greater earthquakes since accurate recording began in 1962. At its heart is the uniquely acute subduction cusp where the Kamchatka and Aleutian Arcs and Emperor Seamount Chain meet. Volcanism and Subduction covers coupled magmatism and tectonics in this spectacular region, where the torn North Pacific slab dives into hot mantle. Senior Russian and American aut...
Tsunamis are infrequent but terrifying hazards for coastal communities. Difficult to predict, they materialize with little warning, claiming thousands of lives and causing billions of dollars in damage. Now a groundbreaking new approach to tsunami detection and warning developed by an international team of researchers that relies on low-cost underwater sensors and networks of smartphone communication gives at-risk coastal communities an economically viable, scientifically sound means to protect themselves. Hazardous Seas, edited by disaster preparedness experts Louise K. Comfort and Harkunti P. Rahayu, is an invaluable guide for policy makers and international NGOs looking to save lives from tsunamis and mitigate crippling damage to communities. It also provides a comprehensive overview of tsunami detection and warning for students of engineering, computer science, planning, policy, and economic and environmental analysis.
