A map of intensity contours is called an isodynamic chart. As the World Magnetic Model shows, the intensity tends to decrease from the poles to the equator. A minimum intensity occurs in the South Atlantic Anomaly over South America while there are maxima over northern Canada, Siberia, and the coast of Antarctica south of Australia. [16]
The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...
America Burning: The Report of The National Commission on Fire Prevention and Control is a 1973 report written by the National Commission on Fire Prevention and Control to evaluate fire loss in the United States and to make recommendations to reduce loss and increase safety of citizens and firefighting personnel.
The threat with this elevated fire risk is due to winds picking up to 10-15 mph, with wind gusts upwards of 25-35 mph. Relative humidity levels are as low as 20% in some spots, as well.
At this time in history fire was viewed as a threat to timber, an economically important natural resource. As such, the decision was made to devote public funds to fire suppression and fire prevention efforts. For example, the Forest Fire Emergency Fund Act of 1908 permitted deficit spending in the case of emergency fire situations. [4]
The following is a chronology of discoveries concerning the magnetosphere. 1600 - William Gilbert in London suggests the Earth is a giant magnet. 1741 - Hiorter and Anders Celsius note that the polar aurora is accompanied by a disturbance of the magnetic needle. 1820 - Hans Christian Ørsted discovers electric currents create magnetic effects.
The Federal Fire Prevention and Control Act of 1974 was created in response to the 1973 National Commission on Fire Prevention and Control report, America Burning. [1] The report's authors estimated fires caused 12,000 deaths, 300,000 serious injuries and $11.4 billion in property damage annually in the United States, asserting that "the richest and most technologically advanced nation in the ...
The United States Fire Administration (USFA) is a division of the Federal Emergency Management Agency (FEMA) located in Frederick County, Maryland, near Emmitsburg. [1] [2] Per the official website, "the mission of the U.S. Fire Administration is to support and strengthen fire and emergency medical services (EMS) and stakeholders to prepare for, prevent, mitigate and respond to all hazards".
