A powerful aftershock tonight brought two apartment blocks crashing down in the stricken city of L'Aquila, causing panic among rescue workers and survivors of Monday's deadly earthquake.

Chunks of masonry fell from other damaged buildings, and the tremor - measured by the US Geological Survey at magnitude 5.6 - was felt as far away as Rome. Within minutes the city resounded again to the scream of sirens as police and rescue workers rushed to the scene.

Meanwhile rescue workers were preparing to carry out what one called a "surgical operation" on a collapsed building in the centre of L'Aquila in the hope of saving the lives of four missing students.

Red River floodwaters head to Canadian province

Saskatoon, Saskatchewan - Manitoba's biggest city of Winnipeg will defend itself against the Red River's highest crest without its prized floodway, an C$858 million ($692 million) ditch designed to channel floodwater around the provincial capital.

Backhoes and specialized ice-breaking machines have instead assembled along the river as the first of two crests, caused by ice jams on the north-flowing river, hits Winnipeg as early as Tuesday.


Huge Sea Worm Captured in Britain

Aquarium staff have unearthed a 'giant sea' worm that was attacking coral reef and prize fish.

The 4ft long monster, named Barry, had launched a sustained attack on the reef in a display tank at Newquay's Blue Reef Aquarium over recent months.

Workers at the Cornwall-based attraction had been left scratching their heads as to why the coral had been left devastated and - in some cases - cut in half.

Concerns Raised About Coastal Levels Of Flame-Retardant Chemicals

U.S. study finds widespread, high concentrations near Southern California and Chicago, as well as Alaska.

Flame-retardant chemicals that have been linked to reproductive and neurological problems in animals have seeped into coastal environments even in remote regions and have been found in high concentrations off populated areas such as Chicago and Southern California, a federal study revealed Tuesday.

"This is a wake-up call for Americans concerned about the health of our coastal waters and their personal health," said John H. Dunnigan, assistant administrator of the National Ocean Service, a branch of the National Oceanic and Atmospheric Administration, which released the report.

Hurricane speed reveals where storm surges will strike

The speed at which a hurricane progresses across the ocean may help forecasters predict which areas are at risk from flooding by storm surges.

When hurricanes strike, flooding causes more damage than the wind, and kills more people. To predict the severity of a surge, forecasters tend to rely on factors such as the size and the intensity of the storm. Now Joao Rego and Chunyan Li of Louisiana State University in Baton Rouge have calculated that a hurricane's forward speed influences the peak height and inland "reach" of surges.

The pair fed measurements from 30 sites in Louisiana and Texas hit by hurricane Rita in 2005 into a computer model that relates the severity of a surge to the hurricane's speed of travel. When they raised the speed in their model to the maximum realistic value, the peak of the surge was 7 per cent higher than Rita's, and the volume of water pushed inland fell by up to 40 per cent. This meant areas close to the coast were hit harder, but sites further inland were left unscathed. For the slowest storms, the opposite happened: peak surge was lower, but inland reach increased (Geophysical Research Letters, DOI: link).
