Comet Schwassman Wachmann 1 OUTBURST + A2 Asteroid Collision

of the 2010 Asteroid Collision

A continuous photometric monitoring of Centaur 29P/Schwassmann-Wachmann 1 is being currently performed from Spain. We have analyzed multi-band images taken in V, R, and I filters on Feb. 3.181, 2010 by A. Sanchez (MPC442). This object exhibits a stellar appearance in the images with an apparent diameter of 15 arcsec. The derived magnitude of the comet in a 10 arcsec standard photometry field is +11.7 R, +11.5 I, and +11.9 V. These data suggest that this comet is currently experiencing an unusual outburst, probably the brightest in the last decade according the recent photometric compilation by Trigo-Rodriguez et al. (2009) A&A 485, 599.

Tsunami sweeps away entire towns on Chilean coast Feb. 27. 2010 TALCAHUANO, Chile – When the shaking stopped, Marioli Gatica and her extended family huddled in a circle on the floor of their seaside wooden home in this gritty port town, listening to the radio by a lantern's light. They heard firefighters urging Talcahuano's citizens to stay calm and stay inside. They heard nothing of a tsunami — until it slammed into their house with an unearthly roar about an hour after Saturday's magnitude 8.8 quake. Gatica's house exploded with water. She and her family were swept below the surface, swirling amid loose ship containers and other massive debris that smashed buildings into oblivion all around them. "We were sitting there one moment and the next I looked up into the water and saw cables and furniture floating," Gatica said

7.2-magnitude aftershock rocks Chile March 11, 2010 SANTIAGO, Chile – The strongest aftershock since Chile's devastating earthquake rocked the South American country Thursday as President Sebastian Pinera was sworn into office. The 7.2-magnitude aftershock was stronger than the quake that destroyed the Haitian capital on Jan. 12. There were no immediate reports of damages or injuries but the temblor — and at least three other aftershocks — strongly swayed buildings — shook windows and provoked nervous smiles among the dignitaries attending Pinera's inauguration at the congressional building in coastal Valparaiso. The biggest aftershock happened along the same fault zone as Chile's magnitude-8.8 quake on Feb. 27, said geophysicist Don Blakeman at the U.S. Geological Survey in Golden, Colorado. "When we get quakes in the 8 range, we would expect to see maybe a couple of aftershocks in the 7 range," he said. Blakeman said Chile now can expect to feel "aftershocks of the aftershock."

Chilean Quake Likely Shifted Earth’s Axis, NASA Scientist Says March 01, 2010, 2:28 PM EST  March 1 (Bloomberg) -- The earthquake that killed more than 700 people in Chile on Feb. 27 probably shifted the Earth’s axis and shortened the day, a National Aeronautics and Space Administration scientist said. Earthquakes can involve shifting hundreds of kilometers of rock by several meters, changing the distribution of mass on the planet. This affects the Earth’s rotation, said Richard Gross, a geophysicist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who uses a computer model to calculate the effects. “The length of the day should have gotten shorter by 1.26 microseconds (millionths of a second),” Gross, said today in an e-mailed reply to questions. “The axis about which the Earth’s mass is balanced should have moved by 2.7 milliarcseconds (about 8 centimeters or 3 inches).” The changes can be modeled, though they’re difficult to physically detect given their small size, Gross said. Some changes may be more obvious, and islands may have shifted, according to Andreas Rietbrock, a professor of Earth Sciences at the U.K.’s Liverpool University who has studied the area impacted, though not since the latest temblor. Santa Maria Island off the coast near Concepcion, Chile’s second-largest city, may have been raised 2 meters (6 feet) as a result of the latest quake, Rietbrock said today in a telephone interview. He said the rocks there show evidence pointing to past earthquakes shifting the island upward in the past.

‘Ice-Skater Effect’

“It’s what we call the ice-skater effect,” David Kerridge, head of Earth hazards and systems at the British Geological Survey in Edinburgh, said today in a telephone interview. “As the ice skater puts when she’s going around in a circle, and she pulls her arms in, she gets faster and faster. It’s the same idea with the Earth going around if you change the distribution of mass, the rotation rate changes.” Rietbrock said he hasn’t been able to get in touch with seismologists in Concepcion to discuss the quake, which registered 8.8 on the Richter scale. “What definitely the earthquake has done is made the Earth ring like a bell,” Rietbrock said. The magnitude 9.1 Sumatran in 2004 that generated an Indian Ocean tsunami shortened the day by 6.8 microseconds and shifted the axis by about 2.3 milliarcseconds, Gross said. The changes happen on the day and then carry on “forever,” Benjamin Fong Chao, dean of Earth Sciences of the National Central University in Taiwan, said in an e-mail. “This small contribution is buried in larger changes due to other causes, such as atmospheric mass moving around on Earth,” Chao said.

Did the Chilean Quake Shift Earth's Axis? March 11, 2010: Pictures of widespread devastation leave no doubt: Last month's 8.8 magnitude earthquake in coastal Chile was strong. How strong? NASA scientists say it might have shifted the axis of Earth itself. "If our calculations are correct, the quake moved Earth's figure axis by about 3 inches (8 cm)," says geophysicist Richard Gross of the Jet Propulsion Laboratory in Pasadena, California. You might think you would have noticed the Earth suddenly tilting 3 inches. But that's not how the "figure axis" works. "The figure axis defines not how Earth is tilted, but rather how it is balanced," says Gross.

Consider the following:

Earth is not a perfect sphere. Continents and oceans are distributed unevenly around the planet. There's more land in the north, more water in the south, a great ocean in the west, and so on. As a result of these asymmetries, Earth slowly wobbles as it spins. The figure axis is Earth's axis of mass balance, and the spin axis wobbles around it. "The Chilean quake shifted enough material to change the mass balance of our entire planet," Gross says. A shifting figure axis is nothing new. On its own, the figure axis moves about 10 centimeters per year as a result of "Ice Age rebound." After the last great glacial period some 11,000 years ago, many heavy ice sheets disappeared. This unloaded the crust and mantle of the Earth, allowing the planet to relax or "rebound" back into a more spherical shape. The rebounding process is still underway and so the figure axis naturally moves. On Feb. 27, 2010, the Chilean quake may have moved the figure axis as much in a matter of minutes as it normally moves in a whole year. It was a truly seismic shift—no pun intended.

Chile Earthquake Moved Entire City 10 Feet to the West March 8, 2010 The magnitude 8.8 quake that struck near Maule, Chile, Feb. 27 moved the entire city of Concepcion 10 feet to the west. Precise GPS measurements from before and after the earthquake, the fifth largest ever recorded by seismographs, show that the country’s capital, Santiago, moved 11 inches west. Even Buenos Aires, nearly 800 miles from the epicenter, shifted an inch. The image above uses red arrows to represent the relative direction and magnitude of the ground movement in the vicinity of the quake. The analysis comes from a project led by Ohio State earth scientist Mike Bevis that has been using GPS to record movements of the crust on Chile since 1993. The area is of particular interest to geoscientists because it is an active subduction zone, where an oceanic plate is colliding with a continental plate and being pushed into the Earth’s molten mantle below.
