YouTube a major platform for news – says new Pew report

According to a new report from the Pew Research Center, “YouTube is becoming a major platform for viewing news.”

By far, the incident that sparked the most interest was the Japan earthquake and tsunami. Pew looked at the most popular videos in the “news & politics” section of YouTube over those 15 months and found that 5 percent of the 260 videos related to the Japanese disaster.

Given that 70 percent of YouTube traffic comes from outside the U.S., it’s not surprising that the top three news videos were related to non-U.S. events. After the earthquake/tsunami, the Russian elections and the unrest in the Middle East topped news-related video views, Pew said.

Natural disasters and political upheavals were the most popular news video topics. People did not figure prominently; “No one individual was featured in even 5 percent of the most popular videos studied here-and fully 65 percent did not feature any individual at all,” Pew found. President Obama, however, was featured in 4 percent of the top videos worldwide, in posts that ranged from speeches to campaign ads from opponents.

As Pew noted, the growth of news videos on YouTube has been a help and a hindrance to traditional news outlets…

Before, after, and a year later – satellite images of the devastation from the Japanese tsunami

On the 1-year anniversary of the earthquake/tsunami that hit Japan, Google Maps updated its imagery all along the coast. This included side-by-side shots of two specific regions, the Shiogama Port and the Sanriku Bridge.

The photos are: years before, days after, one month after, and a year after.

The devastation is incredible, but so is the recovery.

Earthquakes caused by glaciers melting?

An acquaintance in Facebook recently posed the question:

Does global warming cause earthquakes?

After the Eastern Seaboard experienced a 5.8 magnitude earthquake, it left many wondering, what the hell was that?

Before the recent disruption the largest earthquake on record in central Virginia was a magnitude 4.8 temblor that occurred in 1875.

Earthquakes are rare in the eastern U.S. because the region is farther from a fault line.

Andrew Hynes, a tectonics expert at McGill University, said the issue is not so much the load shift on the earth’s crust, but rather the increased fluid pressure in the fault that lubricates the rock, allowing the plate to slide.

 “All earthquakes except those produced by volcanic activity are essentially the unsticking of faults,” he said. In other words, if you pump fluid into a fault, it will reduce the friction and the rock can slide. (from AccuWeather)

Can the added melt from glaciers create stress on the earth’s upper crust, injecting more fluid into the rocks, thus creating earthquakes? The answer is yes, earthquakes at shalllow depths. Which is exactly what states like VA, MD, NY, and NC experienced.

Metereolists and geologists have long been warning of the consequences of “post glacial rebound” when the melting of glaciers causes an increase in global sea levels.

This increase in sea level means more pressure on the sea floor, which can effect everything from gravity fields to horizontal crustal motion. Of course, the recent earthquake on the East coast brings to mind the threat of shifting tectonic plates.

As the world’s glaciers perform an accelerated disappearing act, earthquakes just may be the first sign of how the warming will change the world.

Ginormous nuclear haul from California to Utah

Today the largest truck ever to travel in California transports a nuclear steam generator weighing 750,000 pounds to Utah. The 50 foot long turbine is classified as nuclear waste and is travelling on a truck with 192 tires to a nuclear waste dump in Utah.

The story of the journey is fascinating. A large police escort follows it the whole way. The truck can only travel 15 mph and is so long it can barely turn relying on six robotic pivot points every time. It has one powerful deisel pulling it and two trucks pushing it.

I’m inclined to try to find this truck and bear witness to the behemot (pic), but it’s travelling at night and hoping to avoid the public.

I just love it, there are so many different action adventures movies waiting to be written about it.

To learn more read the OC Register article: Giant nuclear parts: stealth ride to Utah.

The journey starts here in Orange County at my local nuclear power plant in San Onofre, where four new generators were recently installed. The plant is capable of producing 2,200 megawatts and powereing 1.6 million homes.

I’m quite certain that we get our power from a nuclear source which raises some concern for me. Not only do we live in earthquake territory with a nuclear reactor not that far away, but we also sit in a tsunami zone. I definitely need to do some research to see ow safe we are and what to do in the event of emergency.
