Using Statistical and Computer Models to Quantify Volcanic Hazards

Risk assessment of rare natural hazards— such as large volcanic block and ash or pyroclastic flows— is addressed. Assessment is approached through a combination of computer modeling, statistical modeling, and extreme-event probability computation. A computer model of the natural hazard is used to provide the needed extrapolation to unseen parts of the hazard space. Statistical modeling of the a...

Volcanic Ash Can Pose Hazards to Air Traffic

When volcanoes erupt, lava flows are what concern many people. But as air traffic increases, some scientists at agencies in the U.S. and abroad—including the National Oceanic and Atmospheric Administration (NOAA), U.S. Geological Survey (USGS), and NASA—also are focusing on how to avoid costly and potentially deadly problems that can arise from volcanic ash clouds. The clouds can rise into the ...

A Comparative Study on the Status of Elderly In the Traditional and Modern Societies

Over the past two centuries, the rapid socio-economic transformations along with substantial advances in medicine have resulted in decrease of mortality rate, the significant increase of life expectancy, and the growth of the population aging. In despite of the increased proportion of elderly in the recent periods, their status has significantly decreased. Elderly in the traditional societies h...
