According to the U.S. Geological Survey, around 4:45 pm there was a 3.1 magnitude earthquake about 7 miles northeast of Milledgeville and 14 miles Southeast of Eatonton.
Ten minutes later, the USGS reports a smaller 2.2 magnitude earthquake about 14 miles from Milledgeville and 12 miles from Eatonton.
Viewers tell FOX 24 News that they heard an explosion and felt the ground shake.

Australia's Bureau of Meteorology is warning residents of southeastern Queensland, including the state capital Brisbane, of severe weather, including heavy rainfall and possible flash flooding.
Flood warnings have been issued for the Noosa River and Sunshine Coast streams, the Mary River and Six Mile Creek, the bureau said on its Web site. Heavy rains have been recorded in the area for several days.

New rifts detected on ice bridge
New rifts detected on ice bridge
The Advanced Synthetic Aperture Radar (ASAR) images acquired on 2 April by ESA's Envisat satellite confirm that the rifts are quickly expanding along the ice bridge. Dr Angelika Humbert from the Institute of Geophysics, Münster University, and Dr Matthias Braun from the Center for Remote Sensing, University of Bonn, witnessed the recent development during their daily monitoring activities of the ice sheet using data from Envisat and the German Aerospace Center's TerraSAR-X satellite.

The focus of the quake, which occurred at 6:36 p.m., was some 30 km underground in the Hyuganada region of Kyushu. There were no reports of injuries or damage.
No tsunami warning was issued.
The quake registered 4 on the Japanese seismic intensity scale of 7 in the city of Miyazaki and 3 in neighboring areas, according to the agency.

Llaima volcano
Llaima volcano
Llaima, which lies in Chile's picturesque lake region about 435 miles south of the capital Santiago, erupted on January 1, 2008, and has belched rock and ash sporadically since then.
The lava and hot gases from the latest eruption are melting snow on the sides of the volcano, and authorities say some towns are in danger of being hit by mudslides.
The U.S. Geological Survey says East Tennessee was struck by three small earthquakes in eight days.
A magnitude 1.0 quake hit near Madisonville on March 25. A magnitude 1.3 quake hit six miles north of Cleveland in Bradley County on March 29.
WVLT-TV reports a 1.0 magnitude quake hit Thursday at 11:02 a.m., about 12 miles southeast of Tellico Plains in the Cherokee National Forest. The epicenter originated 7.6 miles underground from a ridge near Brookshire Creek.

Trying to find the balance between these two crucial behaviors is one of nature's oldest dilemmas, according to Jeffrey Oliver, a postdoctoral associate in Yale's Department of Ecology and Evolutionary Biology and lead author on the study, which appears online today in the journal Proceedings of the Royal Society B: Biological Sciences.
"You want to be noticeable and desirable for mates, but other onlookers, including predators, are paying attention to those signals as well."
Oliver was interested in whether the eyespots on the upperside of butterflies' wings - specifically, those of bush brown butterflies - serve a different purpose than the ones on the underside. Ever since Darwin's time, biologists (including Darwin himself) have postulated whether the upperside patterns could be used to attract mates, while at the same time, those on the underside could help avoid predators.

Experiments by Dimitri Deheyn and Michael Latz revealed green bioluminescence.
Experiments by Dimitri Deheyn and Michael Latz revealed green bioluminescence.
Many longtime sailors have been mesmerized by the dazzling displays of green light often seen below the ocean surface in tropical seas. Now researchers at Scripps Institution of Oceanography at UC San Diego have uncovered key clues about the bioluminescent worms that produce the green glow and the biological mechanisms behind their light production.
Marine fireworms use bioluminescence to attract suitors in an undersea mating ritual. Research conducted by Scripps marine biologists Dimitri Deheyn and Michael Latz reveals that the worms also may use the light as a defensive measure. The report, published as the cover story of the current issue of the journal Invertebrate Biology, provides insights into the function of fireworm bioluminescence and moves scientists closer to identifying the molecular basis of the light.
"This is another step toward understanding the biology of the bioluminescence in fireworms, and it also brings us closer to isolating the protein that produces the light," said Deheyn, a scientist in the Marine Biology Research Division at Scripps. "If we understand how it is possible to keep light so stable for such a long time, it would provide opportunities to use that protein or reaction in biomedical, bioengineering and other fields-the same way other proteins have been used."
The Mount Redoubt volcano had another large eruption Saturday after being relatively quiet for nearly a week.
Radar indicated a plume of volcanic ash rose 50,000 feet into the sky, making it one of the largest eruptions since the volcano became active on March 22, said the National Weather Service.
The ash cloud was drifting toward the southeast and there were reports of the fine, gritty ash falling in towns on the Kenai Peninsula.

Comment:
Between 1981 and 2007, most of Antarctica warmed. Portions of West Antarctica experienced an especially rapid rise in temperature.
