"An Instant Inland Tsunami"

Queenslanders Told To Prepare For Ongoing Flood Emergencies That Could Last "Weeks, Months"

This is the usually calm, sun baked Queensland city of Toowoomba :



This is Toowoomba in the middle of what a police spokesman called "an instant inland tsunami" :



Yesterday afternoon, the central business district of Toowoomba as was as busy as it usually gets on a Monday. Rain began to fall, some took shelter under shopfronts to wait it out, others climbed into their cars with their kids and shopping and expected a delayed trip home.

Then the rain hammered down. Minutes later, a waist-high wall of water swept through the city centre. Nobody knew it was coming. Nobody could prepare for it. Those caught in it hung on to whatever they could, walls, trees, each other.

Within an hour of the rain beginning, the flood was gone, and shocked survivors climbed out of their battered cars, and exited shops and offices rivering water to stare in disbelief at the devastation.

At least ten people (confirmed so far) are dead from the Toowoomba flash flood.

It ripped children from their parents arms and crashed through the front doors of homes and dragged people out into the churning streets.

Watch the white van at 00:32. A man clings desperately to the tree the van is slammed into. He was later rescued.



ABC News :
Resident Joanne Kruger says it was like being in a disaster movie.

"It was like the tide had come in dramatically, like rolling waves across the road," she said.

------------

People were stranded on roofs in Grantham, near Gatton, where residents say the water rose about a metre every few seconds.

"As far as the eye can see north, south, east and west is just water," one local resident said.

Water, and even water tanks.



The aftermath :





Cars are Mother Nature's play toys. She will toss them around as she pleases.



The Toowoomba Chronicle :
(QLD premier Anna Bligh) said the waters had hit the communities at "lightning speed".

"Mother Nature has unleashed something shocking..."

As an example, the premier said the river at Gatton, east of Toowoomba, had risen 9 metres in the course of the afternoon.

The Courier Mail :

Through Toowoomba city and down to the Lockyer Valley, the torrent washed houses off their stumps and snapped 4m-high trees at the base of their trunks.

Video footage showed families scrambling desperately to get out of their cars as they were washed away in a sea of water.

Landslides and the wild water picked up cars and tossed them into trees, turning the vehicles some with people still inside into missiles.

People cowered on their roofs and pleaded to be rescued as the water engulfed homes.

The Brisbane Times :

"It only takes 15 centimetres of fast flowing water to sweep a person off their feet and into a flooded waterway..."

"It only takes 60 centimetres of floodwater to push a four-wheel drive off the road. "People underestimate the danger of these waters...
As of late Monday night, up to 50 people are still reported as missing.

Queensland's capital Brisbane will be hit by floodwaters starting Tuesday.

At least four more days of heavy rain are expected over the city, and local suburbs.

Dozens of south east Queensland towns and villages are being evacuated, an unknown number of people are spending the night on the roofs of their houses, hundreds of kilometres of road have been washed away, the premier of Queensland, Anna Bligh, has announced the food crops & coal production losses due the weeks of flooding across the state will impact world markets.

Bligh said after weeks of flooding, Queensland was "desperate".

, shortly after 1pm Monday :




UPDATE : The Brisbane Times :
Queenslanders are being warned to prepare for emergencies as unprecedented floods threaten much of the state.

Residents have been told they may need to fall back on their emergency kits in "coming days, weeks and months"...

"This is a very uncertain time for Queensland residents, and even if you don't experience flooding today, it pays to be prepared for the coming days, weeks and months."

"Emergency kits should contain essential supplies of non-perishable foods and water, clothing, medications, torches and batteries, a battery-operated radio and pet supplies."

Headlines from ABC News :

The rain keeps falling.

Pacific Tsunami Hitting New Zealand, Fiji, Tonga, Samoa, New Guinea, Australia




By Darryl Mason

UPDATES OF TSUNAMI REACHING ACROSS ENTIRE PACIFIC BASIN BELOW

(10pm) A massive magnitude 8.8 earthquake has struck off the coast of Central Chile. It's the 7th highest magnitude earthquake ever recorded. A tsunami alert has been issued for Queensland by the Bureau of Meteorology.

Threatened areas extend from Point Danger to Double Island Point :
Possibility of dangerous waves, strong ocean currents and foreshore flooding
for several hours from 08:15 am [EST] Sunday.

Sea level observations HAVE confirmed a tsunami has been generated.

Tsunami waves are more powerful than the same size beach waves, with the first
wave not always the largest. First tsunami effects are expected as follows:

Coolangatta after 08:15 am [EST] Sunday
Maroochydore after 09:00 am [EST] Sunday
Brisbane after 09:15 am [EST] Sunday
And the most important piece of advice :
And probably the most important piece of advice :
Do not go to the coast to watch the tsunami. Check that your
neighbours have
received this advice.
History's largest recorded earthquake, magnitude 9.5, struck Chile in 1960. More than 6000 people died.

The death toll, so far, from today's earthquake off Chile is below 100. That toll is expected to climb, significantly.

UPDATE : Photos, phone videos, news links, eyewitness accounts of the Chile earthquake, and a fast rising panic about the Pacific tsunami are pouring onto Twitter at the rate of a few thousand a minute (at 10.40pm, Sydney time).

Click #Chile and Tsunami to see the Twitter news streams.

The Pacific Tsunami is expected to hit the coasts of the North and South New Zealand islands in about six hours.

UPDATE : Tsunami alerts are scrolling on some Australian TV channels, some appearing during an airing of The Day After Tomorrow, which must be jarring to those who aren't already aware of what's happening.

Tsunami alerts issued for Japan, Alaska, Russia, the east coast of the United States, Indonesia, the Solomon Islands, Fiji, New Guinea....

(10.40) I'll drop the 'update' thing and just keep posting the bits and pieces of news rolling in :

* The entire Pacific Ocean base is now under a tsunami alert.

* The highest tsunami wave (at sea) recorded so far (10:52pm) is 2.2 metres. They tend to get bigger when they reach shallower waters, and coastlines. The waves are expected to roll in for a few hours, but time between each wave can vary from 5 minutes to 60 minutes.

* New Zealand tsunami warnings are dramatic :
"SEA LEVEL READINGS CONFIRM THAT A TSUNAMI HAS BEEN GENERATED WHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKE APPROPRIATE ACTION IN RESPONSE TO THIS THREAT."
* (11.04pm Syd) Evacuations under way on Easter Island, tsunami to hit within an hour.

* Tsunami alerts issued for dozens of countries, even Russia and Antarctica.

(11.20pm Syd) How To Know When The Tsunami Threat Has Passed :
WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

* (11.46pm) CNN reports the Chile earthquake was the biggest to strike anywhere in the world in 100 years. The 8.8 magnitude earthquake has been claimed to have been 1000 times bigger than the quake that struck Haiti.

* (11.50pm) A marine tsunami alert has been issued for New South Wales. :
Threatened areas extend from Broken Bay to Point Danger.

Possibility of dangerous waves, strong ocean currents and foreshore flooding
for several hours from 08:45 am [EDT] Sunday.

Further south from about 8am Sunday for coastal areas from Broken Bay to Gabo
Island, there are likely to be unusual currents and tides during Sunday.

At this stage, those areas, including the coast and bays around Sydney Harbour,
are not considered to be under threat of significant tsunami effects.

* (12.08am) Reuters reports tsunami sirens will be sounded in Hawaii near dawn, "all shores at risk no matter which direction they face." Five metre waves are expected to hit.

* (12.23am) The tsunami wave heading for the east coast of Australia is estimated to be travelling at 800kmh.

* 21 aftershocks have struck Chile, most above magnitude 5, at least seven above magnitude 6.

* Tsunami waves due to hit New Zealand in a few hours are expected to below 1 metre high. Some reports claim evacuations have already begun, others say the perceived threat has been downgraded.

The emergency announcement for the Pacific Tsunami from New Zealand Civil Defence :
1. Stay off beaches
2. Stay out of the water (sea, rivers and estuaries, including boating activities)
3. Do not go sightseeing
4. Share this information with family, neighbours and friends
5. Listen to the radio and/or TV for updates
6. Follow instructions of your local Civil Defence authorities.
* (12.44am) If you're an Australian with relatives in Chile, you can get updates from the Department of Foreign Affairs on hotline : 1800 002 214

* (12.50) CNN via Twitter reports locals claim a 40 metre high (131 foot) wave hit San Fernandez island a few minutes ago. Surely they mean a 4 metre wave?

* (1am) The Pacific Tsunami has begun striking island coastlines near Easter Island. San Fernandez island smashed by huge waves, death toll climbing. Island's capital San Juan Bautista, reports local radio, half destroyed. Partial evacuations now underway on Easter Island.

* (1.10am) Who will the first religious idiot to blame Sydney's Mardi Gras for Australian tsunami damage later today? Hopefully, no-one.

* (1.15am) News from San Fernandez slow to get out. Report that first waves hitting Easter Island are less than a metre high. Some Pacific Tsunami warnings are being downgraded.

* MSNBC airing Chile earthquake twitter reports from an American Idol contestant.

* (1.30am) CNN now running interview with American Idol contestant, Eliot Yamin, showing twoots he wrote during the Chile earthquake. He gives decent eyewitness account of being tossed around his office and then "running for my life" when the massive quake struck.

CNN journalists are now leaving Haiti earthquake destruction to report from Chile earthquake destruction.

* The Pacific Rim Of Fire has been been humming with earthquakes over magnitude 4.5 through the past week (click image to enlarge) :



* (1.30am) California issues alerts, warns coastal cities to prepare for tsunami waves.

* (1.46am) The Joint Australian Tsunami Warning Centre repeating "marine" tsunami expected for New South Wales and Queensland starting at 8am. No major coastal town or city damage expected.

* (2am) A mass nude photo shoot planned for a beach near Weillington this morning has been cancelled due to tsunami alerts. Let's hope that's the worst thing that happens to New Zealand in the next few hours.

* (2.24am) First Pacific Tsunami wave to hit Hawaii in about 45 minutes. Hotels in Maui are being advised to move all guests above the fourth floor. The latest warnings say waves are expected "to wrap around the islands", and the height of tsunamis waves "cannot be predicted."
Honolulu County is issuing urgent warnings for residents to evacuate as roads are about to be closed. Waves as high as four metres are now expected.

* (2.29am) Tsunami alerts issued in Fiji and Tonga warn of incoming waves at least two to three metres high. Police in Samoa have reportedly issued a nationwide evacuation. Terrible.

* (2.33am) Only a few years ago, most tsunamis struck with little or no warning. Tsunami warning centres and monitoring across the Pacific means this time at least many have warnings of what is heading their way, at the speed of a jet. It is likely thousands, if not more, have been saved from the Pacific Tsunami by this warning system. It's been a remarkable and unnerving experience to follow the path of the Pacific Tsunami through Twitter updates and links, Tsunami warning centre alerts and Google Maps these past five hours.

Accurate to almost the minute advance warnings of tsunami wave heights and arrivals were issued 1 - 16 hours before waves hit many Pacific islands, though most in the tsunami's path would have already been in bed when the reports and warnings were issued.

And the earthquakes and aftershocks continue, as the Rim Of Fire grinds, crashes and explodes.
