Inland Tsunami

Inland Tsunami
Floods continue to wreak chaos in northern Australia, as a downpour at night was a "sign of the tsunami killed at least 13 people.

The worst is yet to come. Brisbane River broke its banks, sparking fears that the city - the third in Australia and home to 2 million people - was flooded on Thursday.

And the problem is more, even if the waves away. Public health experts fear epidemics of Ross River virus - a debilitating disease transmitted by mosquitoes, is endemic in Queensland - will increase.

A wall of water up to 2 meters in height, took yesterday Toowoomba and Lockyer Valley in Queensland, killing at least 13 people, overturning cars and demolition of buildings.
 The water is now threatening to Brisbane. Is a rule against periodic flooding of the Brisbane River to protect Wivenhoe Dam, 80 miles? Woven But now is the ability of 81 percent after heavy rain saturated Queensland last month.

To save the Brisbane floods, officials began releasing water from Wivenhoe last month. However, because of the tsunami disaster in the interior and at a full speed toward the city, the authorities have increased the amount of water released 140 million tons yesterday to 344 million tonnes today.

"With all the pools are now in a state of total saturation, additional rainfall was likely seen as extreme runoff events ... in Toowoomba and Lockyer Valley," said Tony Weber, an environmental engineer specializing in the assessment of recruitment Australian National University (ANU) in Canberra.

He says the soil needs time to dry to more flooding, which could take several weeks to prevent - assuming no more rain. 
Tony McMichael, an epidemiologist at the ANU, said that after the flood "there is an increased risk of outbreaks of Ross River virus that is endemic to Queensland. RNA virus Ross River fever mosquitoes are not a disease causing fatal but debilitating. In these hot and humid conditions "mosquito populations more opportunities to play," he said.
