A small earthquake that rattled parts of the Bay Area Monday morning occurred on a previously unknown fault, according to Jack Boatwright, a geophysicist with the U.S. Geological Survey.
The magnitude 4.3 quake hit at 10:40 a.m. and was centered about 11 miles north of Morgan Hill and 16 miles east-southeast of San Jose, according to the USGS.
Personnel at several police departments and the USGS said they had not received reports of any damage. The trembling was felt mildly by residents in various parts of the Bay Area, including in San Francisco.
Boatwright said the small, unmapped fault that appears to have produced the earthquake is believed to be a "splay fault" off the Calaveras Fault, which is itself a branch off the San Andreas Fault. The fault crosses the hills east of San Jose, an area that is difficult to map.

The U.S. Geological Survey confirms that East Tennessee was rocked by its second small earthquake in four days over the weekend.
The most recent quake happened at 2:52 PM on Sunday in Bradley County and had a magnitude of 1.3.
USGS officials say its epicenter was located six miles north of Cleveland, in an open field along Eureka Road. The exact location of the quake was about 10 miles underground.

Travellers caught by surprise in the untimely snow storm
Travellers caught by surprise in the untimely snow storm
When snow begins to melt, people count it as a sure sign of the coming spring. With the Iranian New Year celebrated on March 21 to signal the first day of spring and to mark the revival of nature, many Iranians pack their bags and spend their holidays traveling.
This year, forcing many to cut back on their holidays and shocking many others trapped in roads, 10 to 20 centimeters of snow has blanketed the western part of the country.

A house is surrounded by flood water from the Red River in Fargo.
After the level of the Red River inched downward throughout Sunday and Monday, there was hope that the damage caused by the rising tide was over. An early spring snowstorm, however, has swept into the area, prompting officials to think otherwise.
The river is expected to crest at nearly 12 meters, very close to the top of the city's main dike. Winds of 40 to 65 kilometers per hour are hampering emergency efforts
Last December, the Australian lemuroid ringtail possum was widely reported as the first possible extinction casualty of climate change.
But last week it rose from the dead with ecologists reporting the discovery of three of the creatures and declaring that the species was never feared extinct. But its future is far from certain.
"They have a very limited range - most likely due to an inability to tolerate high temperatures - so they are at risk from future temperature extremes," says ecophysiologist Andrew Krockenberger of James Cook University in Cairns, Australia.
Stephen Williams of James Cook University in Townsville agrees. "There has been a massive decline in one population. One more hot summer could wipe [that population] out."

The 'rise of slime' is coming unless we halt the threatened collapse of marine ecosystems, the Ulster Wildlife Trust said.
Seafloor habitats are being destroyed by overfishing, rising water temperatures and dwindling marine biodiversity, reducing the ability of the seas around Ireland to recover and support humans long-term, the Trust said.
Southern African countries have been hit by the worst floods in years, killing more than 100 people and displacing thousands, as a tropical storm threatened to bring more pain on Saturday.
As Mozambique braced for the arrival of a strengthening tropical storm Izilda, record river levels across the region threatened to exacerbate floods which have already affected hundreds of thousands of people.
Namibia's government declared a state of emergency last week in areas where floods have affected over 350,000 people, 13,000 of whom were displaced, according to numbers released by the United Nations on Friday.

A moderate earthquake rattled parts of Silicon Valley Monday, but there were no immediate reports of damage.
The U.S. Geological Survey said the temblor had a preliminary magnitude of 4.3 and struck at about 10:40 a.m. PDT. It was centered 11 miles north of the city of Morgan Hill, or about 16 miles southeast of San Jose.

A strong 6.0-magnitude earthquake shook Indonesia's Papua region early Sunday, the US Geological Survey said.
The quake, which hit at 2:59 am (1759 GMT Saturday), was centred 135 kilometres (85 miles) southwest of the Papuan provincial capital of Jayapura at a depth of 53 kilometres, the USGS was quoted by AFP as saying.
There were no immediate reports of casualties or damage.
The Indonesian archipelago sits on the so-called Pacific Ring of Fire where continental plates meet, causing frequent seismic and volcanic activity.

Bobwhite quails are typically poor fliers and "not really endurance athletes at all," said researcher Jean-Michel Weber.
Bobwhite quails are typically poor fliers and "not really endurance athletes at all," said researcher Jean-Michel Weber.
The right kind happens to be omega-3 fatty acids, the same fats shown to reduce the risk of cardiovascular disease and lower blood pressure in humans.
After sedentary bobwhite quails were fed a supplement of omega-3 fatty acids for six weeks, their muscles showed a huge boost in the activity of enzymes that improve endurance compared to quails that didn't get the supplement, said a research paper published Friday in the Journal of Experimental Biology.
The same enzymes get more active and improve endurance in human athletes who train very hard for weeks, said University of Ottawa biologist Jean-Michel Weber, who conducted the study with his student Simba Nagahuedi.
