Vulnerability varies significantly within a community and over time. 2. This program can be used to obtain the earthquake ground motion parameters needed to design structures for specific geographic locations in accordance with the latest building code reference documents. When forests are cut, there is less water evaporating which in turn reduces the amount of clouds that are formed. Thus, if the temperature of the ocean or the surface of the land is relatively cool in a certain area, drought may occur in regions that rely on those sources of moisture. Of those, 200,000 moved to California. Biology, Ecology, Earth Science, Meteorology, Geography, Human Geography, Physical Geography, Social Studies, U.S. History, World History.

However, many organisms cannot adapt to drought conditions, and the environmental effects of extended, unusual periods of low precipitation can besevere. In conventional rainfall, water evaporates from local land and water sources during high temperature. Scientists gather paleoclimatic data fromtree rings,sediments found in lakes and oceans,ice cores, and archaeologicalfeatures andartifacts. You can find more information and resources on drought and climate change here: NOAAs monthly State of the Climate drought reports. Other plants only grow when there is enough water to support them. It considers the probability of harmful consequences, or expected losses (deaths, injuries, property, livelihoods, economic activity disrupted or environmentally damaged) resulting from interactions between natural or human induced hazards and vulnerable conditions.

Sources for water may include natural lakes and rivers, manmade reservoirs and groundwater. Information from the Standardized Precipitation Index (SPI) is often used to supplement the PDSI data. Check out a map from the U.S. Department of Agriculture (USDA) to see where drought designated as disasters occurred this year. The cooler waters affect storm patterns by contributing to drier-than-normal conditions in parts of North and South America.

One of the most common forms of risk transfer is Insurance. There are a number of tools used to monitor drought across the U.S. Due to the limitations of each system, data from different sources are often compiled to create a more comprehensiveforecast. There are four (4) main types of vulnerability: 1. The SPI, developed in 1993, is less complex than the PDSI and only measures precipitationnot evaporation or waterrunoff. There are a variety of methods by which these assessments can be conducted and organizations such as the National Oceanic and Atmospheric Administration have even developed their own tools to aid this process: Threat/Vulnerability Assessments and Risk Analysis - Whole Building Design Guide.

Natural resource depletion and resource degradation are key aspects of environmental vulnerability. Drought can be defined as a period of time when a geographical region or area experiences lower precipitation and drier than normal astmospheric conditions that causes water shortage. A hazard is a process, phenomenon or human activity that may cause loss of life, injury or other health impacts, property damage, social and economic disruption or environmental degradation.
