on a day of some of the worst bushfire-weather

conditions ever recorded. Background temperatures reached 46 degrees Celsius (115 °F) and northwesterly winds were over 100 km/h (62 mph). This had been precipitated by an intense heat wave and almost two months of little or no rain.

early evening, bringing with it lower temperatures but gale-force

southwesterly winds in excess of 120 km/h (75 mph). This change in wind direction caused the long eastern flanks of the fires to become massive fire fronts that burned with incredible speed and ferocity towards towns that had earlier escaped the flames.

The loss of life on this day was much larger than

much larger than previous bushfires in the country. The

death toll of Black Saturday is almost double that of Ash Wednesday 1983. The fires affected 78 townships and displaced an estimated 7,560 people. Many of those displaced sought temporary accommodation, much of it donated in the form of spare rooms, caravans, tents, and beds in community relief centres.

Слайд 9 Causes The majorities of the fires were ignited by

Causes The majorities of the fires were ignited by fallen or

fallen or clashing power lines, or were deliberately lit.

Other suspected ignition sources included lightning , cigarette butts, and sparks from a power tool. Also implicated in the underlying conditions was a major drought that had persisted for more than a decade. By early to mid-March, favourable conditions aided containment efforts, and helped to extinguish the fires.
