5.6 Magnitude EQ – South Australia

At approximately 09:25:17 UTC on Friday, March 23rd, a 5.6 magnitude earthquake based on land struck at a depth of 10.7 km (6.6 miles) in the region of the South Australia, 217 km (196 miles) SSW of Alice Springs, Australia. Coords: 10.387°S, 161.262°E … (USGS)

According to Geoscience Australia, the initial arrival was from 09:25:44 – 09:29:14 (UTC).

Geoscience has the depth at 3 km at present. Australia itself does not run over any prominent fault lines, so earthquakes further inland, like this one, are a rarity, though not unheard of.

The epicentre itself was 370 kilometres west-north-west of Oodnadatta, near the Northern Territory-South Australian border.

Weather Alert: Western Australia

Tropical Cyclone Heidi is Crossing WA’s Pilbara coast, bringing fierce winds and heavy rains.

A red alert has been sounded for Port Hedland as storm surges threaten to inundate low-lying parts of the town.

“We’re certainly feeling the full brunt of Cyclone Heidi as she crosses the coast,” Port Hedland Mayor Kelly Howlett told Channel 9 this morning. “She’s certainly packing a little punch at the moment. “We’ve certainly got the wind gusts of about 140km and very heavy rain.” She urged all residents to remain indoors until the official all clear was given. Heidi started making landfall around 4.30am WST (7.30am AEDT). Communities between Pardoo and Whim Creek have all been ordered to shelter, while those further inland were told to gather emergency supplies and brace for Heidi’s wrath.

The Bureau of Meteorology said winds of up to 120km/h had been whipping along the coast overnight, with destructive gusts of up to 150km/h possible. Up to 250mm of rain was possible across central and eastern parts of the Pilbara, the bureau said. A dangerous storm tide was also predicted for coastal areas. The West Australian newspaper reported that Port Hedland’s airport and bulk export port had shut down. Mining firms across the region have sent home all non-essential workers and families were battening down the hatches.

At 6pm last night, the Bureau of Meteorology issued a red alert for coastal and island communities between Pardoo and Whim Creek, including the communities of Pardoo, Port Hedland, South Hedland and Whim Creek. People in these areas should move to shelter immediately if they have not done so already. Evacuation of residents in low-lying parts of Port Hedland to emergency shelters began earlier this afternoon after Fire and Emergency Services Authority issued an emergency warning as Cyclone Heidi intensified. FESA warned that rapid and powerful flooding is likely as a result of dangerous storm tides tonight as Tropical Cyclone Heidi approaches the Pilbara coast.

Storms pelt Australia with Giant Hail stones

December 26, 2011 – The damage bill could run into tens of millions of dollars after hundreds of cars were bombarded, windows in homes and businesses were smashed and roofing was torn away. The State Emergency Service was called to more than 2500 jobs when a series of storm cells intensified dramatically in Melbourne in the afternoon. The worst was a tornado that hit Fiskville, near Bacchus Marsh, west of Melbourne. Severe thunderstorm warnings were issued for many parts of Victoria throughout the afternoon and evening, but the weather was expected to improve ahead of today’s Boxing Day Test at the MCG.

Early this morning, a severe weather warning remained current for parts of southern New South Wales, including Orange, Dubbo, Parkes, Griffith, Broken Hill and Brewarrina.

Around Melbourne yesterday, most calls to the SES were from Keilor Park, Keilor Downs and Taylors Lakes. Parts of Eltham and Greensborough were hit more than once and planes were grounded at Melbourne Airport. Lightning hit the 3AW transmission tower, knocking out its analogue signal and putting it off air to most listeners. About 77 passengers on a flight out of Darwin spent almost four hours at Sale airport after Qantas decided it was unsafe to fly into Melbourne. Metro warned commuters to expect major train delays, with most lines disrupted, and advised passengers to defer non-essential travel. The storm blacked out more than 5000 homes in Port Melbourne, Ballarat, Armadale, Toorak and South Melbourne as families sat down to Christmas dinner.

A family in Apollo Rd, Taylors Lakes, had nine cars damaged and roof tiles and outdoor lights broken when the storm hit about 3.30pm. Robyn Sullivan said the hailstones had been almost as big as tennis balls.

“It was like a roar as it came through,” she said. “I’ve never heard anything like it.”
