WILDFIRES RAGE OUT OF CONTROL IN WEST TEXAS AND TEXAS PANHAMDLE DROUGHT AND WIND EXACERBATE WILDFIRES, WHICH SCORCH 80,000 - 100,000 ACRES MARCH 12 - APRIL 11, 2011 Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA
Natural Phenomena that Cause Disasters Planet Earth’s atmospheric- lithospheric interactions cause: Wildfires
WILDFIRE HAZARDS (AKA POTENTIAL DISASTER AGENTS) FIRE HOT GASES AND SMOKE HOT SPOTS BURNED OUT SLOPES (with increased susceptibility to insect infestation, erosion, and landslides)
WILDFIRE HAZARDS (AKA POTENTIAL DISASTER AGENTS) SUNDOWNER WINDS SANTA ANNA WINDS LOCAL CHANGES IN AIR QUALITY LOCAL CHANGES IN WEATHER
WILDFIRE IN TEXAS PANHANDLE Billowing smoke caused by a wildfire in the Texas Panhandle near Borger, Texas, Sunday, March 12, 2006.
WILDFIRE IN TEXAS PANHANDLE Flames reach heights of 20-30 feet as a wildfire rages on Sunday, March 12, 2006 near Borger, Texas.
FIRE FIGHTERS COME FROM OTHER STATES TO HELP Fire fighters from 25 states joined together in a joint effort to bring a dozen fires under control.
PROBLEMS FOR FIRE FIGHTERS Hot, windy conditions and low humidity, combined with withered shrubs and grasses caused by the drought, made fire fighting more dangerous than usual.
PROBLEMS FOR FIRE FIGHTERS Air tankers usually used to douse massive fires like these could not be flown because of wind gusts of 66 to 60 kph (40 to 50 mph) on some days.
LIGHTNING STRIKES WILDFIRES MANMADE FIRES PROXIMITY OF URBAN AREA TO THE WILDLAND FIRE WIND SPEED AND DIRECTION (DAY/NIGHT) DRYNESS HIGH TEMPERATURES LOCAL FUEL SUPPLY CAUSES OF DAMAGE DISASTER LABORATORIES
