Tsunami Warning for Japan Following Major Quake

A map from the United States Geological Survey shows the location of an earthquake (at bottom left) that has struck off the coast of Japan Monday, October 4A 6.3-magnitude earthquake has struck the island of Okinawa off the coast of Japan, triggering Tsunami warnings.
The Japan Meteorological Agency (JMA) has issued tsunami warning for islands near the quake's epicenter, which is about halfway between Okinawa and Taiwan. The maximum height for waves is expected to be about 1.5 feet from the quake, which JMA measured at 6.4 magnitude.
A preliminary analysis from the United States Geological Survey (USGS) shows that the earthquake was 22.3 miles (35.9 km) deep, a very shallow depth for a quake the JMA said. It struck about 70 miles east of the Ryukyu Islands -- about 1,170 miles southwest of Tokyo, but just 200 miles southwest of Okinawa.
The country's meteorological agency issued a tsunami warning for the Miyakojima and Yaeyama areas of the country, coastal areas on the southernmost part of Japan. Along with the Okinawa islands, they are the three major island chains that make up the country's Okinawa municipality.
The JMA estimated that the tsunami had already arrived, but did not cause any damage, though there may be slight sea level changes.

BIG GREEN COMET:
The icy nucleus of comet 103P/Hartley 2 measures no more than a couple of kilometers across. That tiny nugget, however, is surrounded by an vast atmosphere of gas more than 150,000 km in diameter--about the same size as the planet Jupiter! And it's coming our way. Amateur astronomer Nick Howes sends this picture of the approaching comet from Cherhill, WIltshire UK:
"I photographed the comet on Oct. 1st using a 4-inch refractor," says Howes. "Four hours of exposure time revealed not only the comet's vast green atmosphere but also an emerging tail." Howes describes the processing of the data here.
At present, the comet is a 7th-magnitude object best seen through telescopes. (We recommend the Comet Hunter.) The view will improve, perhaps even to naked-eye visibility, as the comet glides by Earth only 11 million miles away on Oct. 20th.
Two weeks after Comet Hartley has its close encounter with Earth, NASA will have a close encounter with the comet. The Deep Impact/EPOXI spacecraft is hurtling toward Comet Hartley now, and on Nov. 4th it will fly 435 miles from the comet's active icy nucleus. The encounter will mark only the fifth time in history that a spacecraft has been close enough to image a comet's core.
Until then, amateur astronomers can monitor the comet as it glides through the constellation Cassiopeia in the evening sky. A finder chart from Sky and Telescope shows the comet passing by a variety of stars and deep-sky objects, offering many photo-ops in the nights ahead.
