The U.S. Geological Survey has reported that two earthquakes struck within 30 minutes of each other near San Jose late Wednesday.
The first shook the Los Altos Hills approximately 14 miles west of San Jose City Hall at about 11:15 p.m., and was recorded with the preliminary magnitude of 2.3, according to the U.S. Geological Survey.
A second earthquake with the preliminary magnitude of 2.6 reportedly hit the same region at about 11:45 p.m., approximately 13 miles west of San Jose City Hall.

The Flinders Ranges have been shaken by a minor earthquake felt up to 30km from the epicentre near Wilmington.
The quake was felt around 9.50am today and measured 3.5 on the Richter scale.
It is the second-largest quake in SA this year and follows a magnitude 4.5 event north-east of Peterborough on January 26.
Primary Industries and Resources SA seismologist David Love said quakes in the ranges were not uncommon.
"Last year, about 250 earthquakes were recorded in the state and 80 per cent of lose were located in the Flinders and North mount Lofty Ranges," he said.

A deadly Asian parasite that threatens to wipe out millions of bees across England and Wales has become endemic because Whitehall does not know the location of more than half the hives in the country, the National Audit Office reveals today.
The auditors estimate that at least 20,000 beekeepers are unregistered, which means they are never inspected and no action can be taken to eradicate the parasite before it destroys the bee colony, the report warns. The registered number of beekeepers stands at 17,000.
Failure to act could wipe out the country's £100m apple harvest and seriously damage pear, raspberry, strawberry and runner bean crops because they are highly dependent on bees for pollination.
The Department for Environment, Food and Rural Affairs describes the pest as varroa, "a serious Asian parasitic mite of honey bees".
One of the more acrimonious scientific debates of the decade may have ended with the publication of a study showing that genetically modified material did contaminate native corn in the crop's birthplace in southern Mexico, scientists said Wednesday.
But Elena Alvarez Buylla, author of the article published in the February edition of Molecular Ecology, said the difficult atmosphere surrounding the original debate - which threatened the reputations of some scientists - persists.
The controversy started in 2001 with an article in the journal Nature, which said that biotech genetic material had been detected in native Mexican corn in the southern state of Oaxaca, where the crop was first developed thousands of years ago.

Global warming is not a crisis, but it may be creating a crisis of intellectual integrity.
Last month, college campuses held a "National Teach-in on Global Warming Solutions." The thrust of the message was that there is a crisis because global temperatures are rising, endangering the world's future, and humans are to blame.
I agree that there may be a crisis, but I don't believe that it is a crisis of impending heat; it is, rather, a crisis of intellectual integrity.
First, let me point out something that most people may not realize. Since 1998, there has been no trend in world temperatures, neither up nor down, in spite of population growth, greater resource use, and lots of carbon dioxide production. True, 1998, was the warmest year on record, and we are still in a warm period, but world temperatures are no higher than when today's college seniors began middle school. The likelihood of the catastrophic effects that gave Al Gore a Nobel Peace Prize is weak.
The crisis that concerns me stems from the way that scientists are addressing the issue. Ever since 1988, when James Hansen, head of NASA's Goddard Institute for Space Studies, alerted a congressional committee to global warming, climate change has been a political issue.

For those who have endured this winter's frigid temperatures and today's heavy snowstorm in the Northeast, the concept of global warming may seem, well, almost wishful.
But climate is known to be variable - a cold winter, or a few strung together doesn't mean the planet is cooling. Still, according to a new study, global warming may have hit a speed bump and could go into hiding for decades.
Earth's climate continues to confound scientists. Following a 30-year trend of warming, global temperatures have flatlined since 2001 despite rising greenhouse gas concentrations, and a heat surplus that should have cranked up the planetary thermostat.
"This is nothing like anything we've seen since 1950," Kyle Swanson of the University of Wisconsin-Milwaukee said. "Cooling events since then had firm causes, like eruptions or large-magnitude La Ninas. This current cooling doesn't have one."

Inbreeding among Asiatic lions hampers their reproductive success by sabotaging their sperm.
Inbreeding among Asiatic lions hampers their reproductive success by sabotaging their sperm.
It's a triple whammy for male animals on the brink of extinction: not only are there fewer mates around to have sex with, but, to make things worse, their sperm are more likely to carry genetic abnormalities and less likely to be good swimmers, research shows.
"It is logical that endangered species are inbred and suffer reductions in fitness, but we don't have a clear idea of what is the driving force behind this," says John Fitzpatrick of the Centre for Evolutionary Biology at the University of Western Australia in Perth.
Fitzpatrick and colleague Jonathan Evans compared existing data on sperm fitness for 20 endangered and non-endangered species of mammals, including the Florida panther, Asiatic lion and cheetah. Scientists have previously observed extreme reductions in sperm quality for each of these big cats - all of which also suffered huge reductions in population size that led to inbreeding.

Menemerus bivittatus is one of three species of jumping spider that steal food from ant columns.
Menemerus bivittatus is one of three species of jumping spider that steal food from ant columns.
At Mbita Point on the shores of Lake Victoria in Kenya, the walls of the buildings and other surfaces are covered with insects, including thousands of tiny lake flies. Within the throng lurks Menemerus, one of the jumping spiders or saltacids.
These predatory spiders adopt an approach similar to the big cats when hunting. They move very slowly, with their body close to the ground, before leaping on their prey.
Stalking is helped by extremely good vision: there are eight eyes in total, and importantly, two that face forward. These anterio-medial eyes have a visual acuity about one sixth as good as humans and let them "see like a primate and hunt like a lion," says Simon Pollard from the University of Canterbury in Christchurch, New Zealand, who led the study.
Jumping spiders are also are known to be capable of solving cognitively complex tasks.
Greek authorities say a strong earthquake struck the southeastern Aegean overnight, but did not cause any damage or injuries.
The Athens Geodynamic Institute says the quake had a preliminary magnitude of 5 and struck just after midnight on Tuesday morning (2200GMT Monday).
Its epicenter was located beneath the seabed 170 miles (300 kilometers) southeast of Athens, between the islands of Kos and Astypalaia.

Mudslides that followed the 12 May 2008 Wenchuan, China earthquake, ranked by the US Geological Survey as the 11th deadliest earthquake ever recorded, may cause a carbon-dioxide release in upcoming decades equivalent to two percent of current annual global carbon emissions from fossil fuel combustion, a new study shows.
Mudslides wipe away plants and topsoil, depleting terrain of nutrients for plant regrowth and burying swaths of vegetation. Buried vegetable matter decomposes and releases carbon dioxide and other gases to the atmosphere.
The expected carbon dioxide release from the mudslides following the Wenchuan earthquake is similar to that caused by Hurricane Katrina's plant damage, report Diandong Ren, of the University of Texas at Austin, and his colleagues, who used a computer model to predict the ecosystem impacts of the mudslides.

Comment: The strength of the global warming psychology jumps out at the reader in this article. Buried within the text is the point that the planet is in a cooling phase.
But the behavioral reinforcement (mind training) of the global warming meme is so strong that the scientists and journalists can not even hear the absurdity in their own words.
