Natural Phenomena that Cause Disasters
Planet Earths atmospheric-hydrospheric-lithospheric interactions create situations favorable for FLOODS
A DISASTER is --- --- the set of failures that overwhelm the capability of a community to respond without external helpwhen three continuums: 1) people, 2) community (i.e., a set of habitats, livelihoods, and social constructs), and 3) complex events (e.g., floods, wildfires, ...,) intersect at a point in spaceand time.
Disasters are caused by single- or multiple-event natural hazards that, (for various reasons), cause extreme levels of mortality, morbidity, homelessness, joblessness, economic losses, or environmental impacts.

AUSTRALIAS WORST FLOODSLook at what happened in 2010-2011?
RECORD FLOODING IN AUSTRALIA:NEW SOUTH WALESROCKHAMPTONTOOWOOMBABRISBANE
DECEMBER 10 JANUARY 16, 2011
75 % OF QUEENSLAND A DISASTER ZONE
DECEMBER STORMS BROUGHT HEAVY RAINFALL: DEC. 17, 2010
IMPACTS: GREAT QUEENSLAND FLOODING INUNDATED 22 TOWNS, DISPLACED 200,000, KILLED 35, AND CAUSED LOSSES OF OVER $5 BILLION
NEW SOUTH WALES: 45 FLOOD DISASTER ZONES
INUNDATED ROADWAYS SHUT DOWN TRUCKS
TOWN OF THEODORE: INUNDATED

TOWN OF BUNDABERG INUNDATED
TOWN OF BUNDABERG INUNDATED
TOWN OF BUNDABERG: INTERIOR DAMAGE
THE SECOND PHASE OF FLOODING HAPPENED IN JANUARYAN AREA OF FLOODING THE SIZE OF FRANCE AND GERMANY (OR, TEXAS AND NEW MEXICO) COMBINED WAS CREATED IN QUEENSLAND
ROCKHAMPTON HIT HARDRockhampton, a town of 77,000 people 370 miles north of Brisbane, lies close to the coast, on the Fitzroy, one of Australia's largest river systems.
ROCKHAMPTON ISOLATEDAll main routes to the south, north and west of the city were cut off by the rising water, rail lines and the airport runways were submerged, and floodwaters stretched for several miles in each direction.
ROCKHAMPTON: LIKE AN ISLAND, JANUARY 3, 2011
QUEENSLAND: WIDESPREAD IMPACTSSocioeconomic impacts for about 200 thousand people included: industrial slow-down, evacuations, a plague of snakes and crocodiles, and health care problems associated with evacuation and water-borne diseases.
FLEEING WITH POSSESSIONS: JANUARY 3, 2011
INUNDATED AIRPORT RUNWAYS: JANUARY 3, 2011
SANDBAGGING: JANUARY 3, 2011
FITZROY RIVER STILL RISING: JANUARY 3, 2011
FITZROY RIVER PEAKED AT 9.2 M: JANUARY 6, 2011
W ILDLIFE AFFECTEDThe local wildlife was caught off-guard by the flooding; bewildered and hungry kangaroos moved to high ground, and cattle were left lost and confused by the excessive water that inundated everything.
FLOOD WATERS IMPACT COAL INDUSTRY: JAN 7, 2011
COAL MINING INFRASTRUCTURE AFFECTED Australia's coal industry faced months of disruption as the result of key rail and road links being washed away during the flooding, and repairs of some infra-structure expected to take a year or more.
THE THIRD PHASE OF FLOODING BEGAN WITH A FLASH FLOOD
JANUARY 11, 2011
FLASH FLOOD IN TOOWOOMBAThe flash flood, which brought a one kilometer wide wall of water into Toowoomba, was triggered by a freak storm with up to 150 millimeters (6 inches) of rain in half an hour.
FLASH FLOOD BRINGS WALL OF WATER: TOOMOOMBA: JAN 11, 2011
IMPACTSCars were transformed into boats and then scrap metal as they floated away; giant metal industrial bins were tossed about as if made of paper; and houses were torn off their foundations.
THE FOURTH PHASE OF FLOODING BEGAN IN BRISBANE
JANUARY 11 AND FOLLOWING
BRISBANEThe city is protected by a large dam built upstream after floods devastated the downtown in 1974, but the reservoir was full, so officials had no choice but to release water, which caused flooding before the FLOOD.
BRISBANEMORE than 50 suburbs were flooded as the Brisbane River rose to 4.5 m or more above flood stage, with some areas being completely inundated.
BRISBANE PREPARING FOR FLOODING: JAN 8, 2011
BRISBANE: BEFORE FLOODING
BRISBANE: AFTER FLOODING
BRISBANE FLOODING: ADMIRALTY TOWERS; JAN 11, 2011
BRISBANE FLOODING: JAN 11, 2011
BRISBANE FLOODING: JAN 11, 2011
BRISBANE RIVER CRESTED AT 4.46 M: JAN 12, 2011
EMERGENCY SERVICESA difficult situation was made even more so by thunderstorms, high winds, raging rivers, and driving rain that made it very hard for helicopters and boats to reach and rescue flood victims.
WATER: URGENT NEEDS The Lockyer Valley Council, west of Brisbane, reported that its town water supply had failed and only hours of reserves remained for some towns
LESSONS LEARNED ABOUT DISASTER RESILIENCEALL FLOODS EARLY WARN-ING (THE ISS) AND EVACU-ATION ARE ESSENTIAL FOR DISASTER RESILIENCE
LESSONS LEARNED ABOUT DISASTER RESILIENCEALL FLOODS RECOVERY AND RECON-STRUCTION USUALLY MEANS STARTING OVER.
IT CAN BE DONE!TOWARDS FLOOD DISASTER RESILIENCE, BUT FLOODS KEEP HAPPENING
FLOODING IN SOUTHEAST AUSTRALIA: MARCH 1-6, 2012
PREPARATION FOR WORST FLOODING SINCE 19749,000 people were evacuated after a week of rain and flooding that damaged 1,000 housesLocal authorities declared a state of emergency, which gave police and the army more authority to carry out search and rescue ops.
The Mummumbidgee River, swollen after 20 cm (8 in) of rainfall, peaked at 10.56 m, just below the height of Walla Wallas protective levee.
