Submarine Volcano Erupts Near Japan

Posted by feww on February 6, 2010

Fukutokuokanoba submarine volcano erupts

White smoke was observed rising from the sea about five kilometers north-northeast of the Minami-Iwoto island in Ogasawara Islands, a Japanese coast guard patrol vessel reported, Yomiuri Shimbun said.

Smoke believed to be emanating from an underwater volcano was previously detected in the area, about 1,200 kilometers south of central Tokyo, in July 2005.

Tokyo Institute of Technology geoscience Professor, Kenji Nogami, reportedly said: “In the 1986 eruption, a new island appeared after lava accumulated. The island was washed away by waves, but seabed upheaval reduced the water depth to 22 meters in 1999. It’s possible that this [recent] volcanic activity could form a permanent island.”

The volcano reportedly ejected  smoke and ash to a height of about about 100 meters above the sea level. The surrounding sea area was reported as changing to a greenish yellow color with other nearby areas turning cloudy.

Japan’s Meteorological Agency (JMA) said the volcano, called Fukutokuokanoba, has erupted seven times since 1904, forming ephemeral islands (temporary land masses) on three occasions, all of which later sank below the ocean surface.

The first known ephemeral island called Shin-Iwo-jima (New Sulfur Island) was formed in 1904, and the most recent in 1986.

Humongous Snowstorm Paralyzes Eastern U.S.

Posted by feww on February 6, 2010

Snow Forecast: Record 76 cm (30 in)

Snowfall totals of up to 76 cm are forecast from Virginia to southern New Jersey

Virginia, Maryland and Delaware  declare states of emergency amid “snowpocalypse,” and put the National Guard on alert

A ferocious blizzard caused by at least 12 inches of snow, as of posting (and mounting),  and 64 km/h  (40 mph)  winds in what is dubbed as “snowmageddon” is pummeling the US mid-Atlantic.

The authorities canceled all flights at Washington’s Reagan National airport, allowing only a few international flights to operate at Dulles International, news reports said.

The blizzard forced the U.S. govt offices in the Washington area to close after lunch yesterday.

Virginia Department of Transportation, VDOT said it had less than 6% of the state’s snow removal budget left, with the lion’s share already spent during the earlier blizzard in December.

About 20,000 homes have lost power in the Washington area as power lines and tree branches snapped under heavy snow.

The blizzard is the second to strike the area since December, when another storm dumped about 41 cm (16in) of snow in the Washington area.

Forecasters have predicted more than 76 cm (30 inches) of snow, for the area, some 5 cm (2 in) more than the all time record of 28 inches set in 1922.

  • Tropical Cyclone OLI has been tracking  southeast over the past 6 hours.

Current Wind Distribution:

  • Maximum Sustained winds: ~ 169 Km (~ 91 kt)
  • Maximum Gusts:  ~ 204 km/hr (~ 110 kt)
  • Cyclone OLI is currently a Category 2B Hurricane

Top 10 Messages from Pluto

Posted by feww on February 6, 2010

Keep Your Paws Off PLUTO!

10 Messages From Plutonians Might Send NASA

10. Keep your paws OFF Pluto.
9. This is a decent planet inhabited by intelligent folks.
8.
You call it Solar System; we call it home!
7. Pluto’s moons are unlike your moon, but you wouldn’t know the difference, would you.
6. We deal severely with junk dumpers in the space.
5.
We don’t wish to pass your fertility test.
4.
There’s more water on your moon than on Pluto’s moons [and we didn’t have to rape our moons to find out, you Neanderthals.]
3. Think universal;
stay local!
2. You can’t go to Mars via Pluto, or by way of your moon for that mater.
1. We have landed on
Charon, our largest moon; what’s taking you guys so long?

‘Pluto has become significantly redder, while its illuminated northern hemisphere is getting brighter.’ NASA

Images below are purported to be NASA’s most detailed images of planet Pluto. ‘Hubble Space Telescope show an icy, mottled, dark molasses-colored world undergoing seasonal surface color and brightness changes.’ NASA said.

‘These changes are most likely consequences of surface ice melting on the sunlit pole and then refreezing on the other pole, as the dwarf planet heads into the next phase of its 248-year-long seasonal cycle. Analysis shows the dramatic change in color took place from 2000 to 2002.’

The distant dwarf, Pluto, was discovered in 1930, but had to wait until NASA’s Hubble Space Telescope could map it in detail more than 6 decades later.

But does NASA’s account of ‘seasonal surface color and brightness changes’ correctly explain the image differences? When is Hubble due in for another service?


[February 4, 2010.] New Hubble Maps of Pluto Show Surface Changes. Since its discovery in 1930, Pluto has been a speck of light in the largest ground-based telescopes. But NASA’s Hubble Space Telescope has now mapped the dwarf planet in never-before-seen detail. The new map is so good, astronomers have even been able to detect changes on the dwarf planet’s surface by comparing Hubble images taken in 1994 with the newer images taken in 2002-2003. The task is as challenging as trying to see the markings on a soccer ball 40 miles away.

Hubble’s view isn’t sharp enough to see craters or mountains, if they exist on the surface, but Hubble reveals a complex-looking and variegated world with white, dark-orange, and charcoal-black terrain. The overall color is believed to be a result of ultraviolet radiation from the distant Sun breaking up methane that is present on Pluto’s surface, leaving behind a dark, molasses-colored, carbon-rich residue. Astronomers were very surprised to see that Pluto’s brightness has changed — the northern pole is brighter and the southern hemisphere is darker and redder. Summer is approaching Pluto’s north pole, and this may cause surface ices to melt and refreeze in the colder shadowed portion of the planet. The Hubble pictures underscore that Pluto is not simply a ball of ice and rock but a dynamic world that undergoes dramatic atmospheric changes. Source: Hubble/NASA Press Release
