US, California: 3.3-magnitude earthquake shakes Sonoma County

A 3.3-magnitude earthquake bounced southern Sonoma County Monday morning, followed by three smaller quakes in the same area, according to U.S. Geological Survey data.

The quake was felt at least north to Santa Rosa. Some folks in the south county said the first quake was a sharp, quick jolt. There was no report of any damage.

At Kenilworth Junior High School in Petaluma, Jackie Watt was working in the kitchen at the time.

"It almost sounded like a plane landed on the roof," said Watt.

Her rolling work chair shifted a few inches and her computer screen jiggled back and forth.

"It got louder and louder," Watt said. "Everything rattled in the kitchen."

The death toll from one of the region's most-intense hot spells in the 138-year period of record has reached at least 18.

And that's probably a substantial undercount, in the view of one heat-mortality expert.

The Health Department added eight additional heat-related deaths to the list today, bringing the Philadelphia total to 15.

Three others were reported in neighboring counties as a result of the fifth, longest and most-oppressive heat wave of the season.

The big clean up is well underway across the country following yesterday's record snowfalls in what may well end up being the coldest day of 2011.

Most state highways have now reopened and city councils in Dunedin and Christchurch have set about clearing most of the local roads of snow and ice.

Snowfalls made way to harsh frosts this morning, particularly in the South Island, although some snow is expected on Arthurs Pass, Milford Rd and the Desert Road later today.

Westerlies are forecast to strengthen over the South Island today, with heavy rain forecast of the west of the country, however temperatures are forecast to pick up following a frigid past few days.

WeatherWatch head analyst Philip Duncan said yesterday may well have been the coldest day of the year.

The national high was just 12 degrees recorded in Northland yesterday.

US: Sinkhole shuts down portion of US 41 in Brown County, Wisconsin

Suamico - A quarter-mile of a southbound lane of U.S. 41 in northern Brown County was closed for 9ยฝ hours Tuesday after a 5-foot by 3-foot sinkhole in the road developed in the morning.

The sinkhole opened about a half-mile south of Brown Road when soil infiltrated a concrete culvert pipe and the pavement above the pipe sank, according to the state Wisconsin Department of Transportation.

"It doesn't happen very often, but it obviously happens," said Kim Rudat, a DOT spokesperson.

The sinkhole opened at 8:30 a.m. and shut down the affected southbound lane until about 6 p.m.

No injuries reported as street closed

This was more than just a regular pothole.

Town of Carman work crews were called out to 2nd Ave SE near the corner of First Street SE after receiving a call about a large sinkhole approximately six feet by five feet and about five feet deep, on the street.

Sonja Morrison, who lives near the site with her family, said they heard a "thump" and then a second louder one when they went outside their home to take a look at around 5:15 p.m. on Monday (July 25).

US: Cracks and sinkholes form in creekside yards - Pensacola, Florida

Sinkholes spawned by erosion raising calls for city action

For seven years, Leanne Pickering has watched as erosion and sinkholes expanded in the backyard of her Pensacola home, and she now wonders when they will overtake her swimming pool.

They are getting close; a 5-foot-deep sinkhole currently is within 6 feet of her pool's enclosure.

In 2002, Pickering built her home in a Creek Side Circle neighborhood near Airport Boulevard and Davis Highway that backs up to Carpenter's Creek.

Before long, she noticed her backyard was steadily falling into the creek. She found soft spots in the grass. Sinkholes began to form. Every year for the last five years, she has paid to have a truckload of dirt dumped into the largest hole. The hole continues to grow.

US: Sinkhole in Palatine, Illinois could take two weeks to fix

It could take up to two weeks before crews completely repair a 15-by-20-foot sinkhole that opened up Saturday afternoon at Dundee and Hicks road in Palatine.

The good news, however, is that the Illinois Department of Transportation agreed to a request from village officials to resume southbound traffic on Hicks, which had been restricted most of Monday, Village Manage Reid Ottesen said.

"Traffic will begin flowing a lot better, but it's still an area to avoid if at all possible," Ottesen said.

The sinkhole formed at the northwest corner of the intersection after the heavy rainfall caused a sewer line to collapse about 30 feet below the surface. Readings showed 5.43 inches of rain fell on Palatine between midnight Friday and 3 a.m. Saturday, exceeding 100-year event standards, Ottesen said.

US: Florida insurance corporation seeking big premium increase on sinkholes

Florida's largest insurer of homes and businesses, state-backed Citizens Property Insurance Corp., will ask its board to approve a staggering rate increase for providing coverage on sinkhole policies, a company spokeswoman said Monday.

The company will ask its board Wednesday for an increase on average of more than 400 percent to purchase sinkhole coverage. In 2010, Citizens received about $32 million in premiums for sinkhole coverage with ultimate losses and loss-related expenses estimated to total $245 million. In areas where sinkhole claims have been particularly high, premium increases could be multiplied 20 times or more under the proposal.

Since the last major hurricane hit Florida in 2005, sinkhole claims have skyrocketed, totaling nearly $2 billion in the last four years. Most of the claims have come from Hernando, Hillsborough and Pasco counties, part of the Tampa Bay area.

ATS Euromaster is urging motorists to pre-order cold weather tyres after a meteorologist predicted this winter will "break all records" in terms of snowfall and freezing temperatures.

Specialist long-range forecaster James Madden, of Exacta Weather, correctly predicted the harsh conditions experienced over the last two years and gave his forecast to ATS Euromaster as it prepares to fit cold weather tyres in the UK for the second year running.

He warns: "The UK is to brace itself for well below average temperatures and widespread heavy snowfall throughout winter 2011/2012 which will result in the fourth bad winter in succession, and will prove to be the worst of them all.
