Volcanoes
Seismologists at the University of Washington have been monitoring the quakes.
A 2.6 quake occurred at 2:26 p.m. on Saturday about six miles north of the volcano. Another quake, a 2.5, occurred at 2:44 p.m. in the same area. The depth for both quakes was two miles. Another quake occurred six miles north-northwest at 10:48 p.m. That measured 2.2 and was 2.2 miles deep.
Smaller quakes, ranging from magnitude 1.3 to 2.2, occurred on Sunday.
Dome growth was accompanied months later by a series of lava flows which cascaded down the southwestern flank of the mountain, stretching up to 3,100 meters (10,000 feet) from the summit. Since then dome growth has continued, with a few periods of actively flowing lava. As of March 2010, the dome was growing about 2,000 cubic meters (70,000) cubic feet a day, leading to frequent small rockfalls and occasional ash plumes. In January 2011, local newspapers reported "dust plumes" rising over Colima, likely pulverized lava stirred up by landslides at the summit dome.
More than 600 residents of the town of Takaharu in Miyazaki prefecture, on the eastern outskirts of the erupting Mount Shinmoedake, were sheltering in school gyms and community halls, an official said.
Municipal authorities had issued an evacuation advisory for 1,158 residents in high-risk districts near the 1,421-metre (4,689-foot) volcano earlier Monday.
The volcanic eruption was accompanied with powerful lightning display and lava ejections, sending residents within 1.2 mile radius to evacuate. This is according to National Geographic.
Watching it from afar provides an "awesome" view of the eruption with the vibrant colors emitted by the volcanic lightning.
The Shinmoedake Peak is a part of the famous Mount Kirishima Volcano group, and is located in Kyushu. Included in the volcano group are Mount Karakuni, Mount Shinmoe, and Takachihonomine. The highest peak is Mount Karakuni which is 1,700 meters above sea level.
The Meteorological Agency raised the volcanic alert to level 3 as ash today continued to spew from Shinmoedake on Japan's southernmost main island of Kyushu, and residents have been banned from going within a mile of the volcano following its worst eruption in 50 years.
Ash from rumbling Mount Bromo, a popular attraction in East Java province, had spread to the island popular with foreign tourists and surfers.
"We received information from Darwin that the ash from Bromo has reached 5,500 metres in the southeast direction and has affected some parts of Bali," transport ministry spokesman Bambang Ervan told AFP.
"As a safety precaution, we've sent out an advisory to airlines to warn them about the ash situation so air crew can avoid the affected areas," he added.
Indonesian aviation authorities were monitoring the situation but there were no plans to temporarily close the airport yet, he added.
"The airport is still open, some flights are still landing. We're checking how bad the situation is and how much worse it can get before deciding what the next step will be," Ervan said.

Pakistani fishers reported the new mud volcano in the Arabian Sea in late November, and NASA's Earth Observing-1 satellite snapped a picture of it (above) on January 11. The volcano was not in a satellite picture of the same region taken last February.
According to NASA, mud volcano "islands" have appeared in the Arabian Sea before, and most have washed away within a few months. In fact, the January picture shows tan sediments steaming from the new mud volcano, suggesting it is eroding and will soon vanish.
Mud volcanoes, which can appear on land or underwater, form when underground layers of silt or clay become pressurized either by tectonic activity or by a buildup of hydrocarbon gases.
The volcano is located in southern Japan, along the pacific ring of fire, and is uniquely situated directly above a tectonic plate boundary.
Kirishima has erupted 9 times during the past 100 years, 2 of which were classified as VEI-2 eruptions (Volcanic Explosivity Index). The last VEI-2 eruption was during 1959 when it pumped 3.2 million cubic meters of 'tephra' up onto the planet surface and into sky. Time will tell how this new eruption will be classified.
Volcanic Ash in the atmosphere will severely damage jet engines, and can cause global temperatures to decrease depending on quantity.
"Seismologists registered about 200 local tremors in the vicinity of the volcano over the past 24 hours," the spokesman said.
According to him, bad weather satellites cannot track the direction or the distance of the ash plume which has repeatedly caused falling ash in populated areas on the peninsula, including Petropavlovsk, where 60% of the Kamchatka Peninsula residents live.
However, the ash could affect the operations of aircraft. Particles of ash may get into the mechanisms of airliners and provoke an accident.
There are more than 150 volcanoes on Kamchatka, 29 of them active.

Indeed, Africa is starting to split apart. The first tear came in the last million years, resulting in the Red Sea and the Gulf of Aden. And now the earth is opening up in a massive expanse of land stretching south from Ethiopia to Mozambique.
The fissures began appearing years ago. But in recent months, seismic activity has accelerated in northeastern Africa as the continent breaks apart in slow motion. Researchers say that lava in the region is consistent with magma normally seen on the sea floor -- and that water will ultimately cover the desert.
Cynthia Ebinger, a geologist from the University of Rochester in New York, could hardly believe what the caller from the deserts of Ethiopia was saying. It was an employee at a mineralogy company -- and he reported that the famous Erta Ale volcano in northeastern Ethiopia was erupting. Ebinger, who has studied the volcano for years, was taken aback. The volcano's crater had always been filled with a bubbling soup of silver-black lava, but it had been decades since its last eruption.
The call came last November. And Ebinger immediately flew to Ethiopia with some fellow researchers. "The volcano was bubbling over; flaming-red lava was shooting up into the sky," Ebinger told Spiegel Online.
The earth is in upheaval in northeastern Africa, and the region is changing quickly. The desert floor is quaking and splitting open, volcanoes are boiling over, and seawaters are encroaching upon the land. Africa, researchers are certain, is splitting apart at a rate rarely seen in geology.
