A dome of lava grows larger inside the crater of Mount Shinmoedake in the Kirishimna range on Japan's southernmost main island of Kyushu Monday, Jan. 31, 2011. Officials urged more than 1,000 residents to seek safer ground on Monday and expanded a no-access zone around the 4,662-foot (1,421-meter) volcano that has exploded back to life. The volcano erupted last week for the first time in 52 years.
A revived volcano in southern Japan erupted Tuesday with its biggest explosion yet, shooting out a huge plume of gas, boulders and ash and breaking windows 5 miles (8 kilometers) away.

The danger zone around Shinmoedake volcano was widened to keep residents safe. The largest eruption since it burst back to life last week covered wide areas in ash, shot boulders onto distant roads, knocked down trees and broke hundreds of windows in hotels and offices.

No serious injuries have been reported since the initial eruption last Wednesday, but public broadcaster NHK said a woman suffered cuts from shattered glass in Tuesday's blast.

NHK said the eruption was five times larger than the initial activity last week, which was Shinmoedake's first major eruption in 52 years.

Japan's Meteorological Agency has restricted access to the mountain, and on Tuesday broadened the no-go zone to anywhere within a 2 1/2-mile (four-kilometer) radius of the crater. Two lodges and scattered homes are within the perimeter.

Dozens of domestic flights in and out of Miyazaki - about 590 miles (950 kilometers) southwest of Tokyo - were grounded last week and more cancellations followed. Train service was temporarily suspended in the area and many schools closed.

The local government also reported damages to crops.

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.

Colima Volcano, Mexico's most active, has been erupting since 1998. The eruption began with several months of earthquakes beneath the volcano, followed by explosions and rockfalls at the summit lava dome as it began to grow.

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.

Hundreds evacuate as Japan volcano erupts

Mount Shinmoedake has been belching smoke and ash into the air since late Wednesday
Tokyo - Hundreds of people living near a Japanese volcano that has been spewing columns of smoke and ash thousands of metres into the air were forced to evacuate their homes Monday, a local official said.

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.

Shinmoedake Peak in Japan Erupts Dramatically with Powerful Lightning Display

Shinmoedake Peak in Japan erupted last January 26, 2011, and alert level was raised to 3 as of January 27, 2011. This is because the volcano spurted lava, 2.5 km into the air.

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.

Lightning and fire: Japan on alert after volcano's biggest eruption in 50 years

A one-mile cordon has been established around a volcano on Mount Kirishima after it erupted scattering rocks and ash across southern Japan and sending smoke billowing 5,000ft into the air.

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.

Jakarta - Several international flights to and from the resort island of Bali were cancelled or diverted Thursday to avoid dangerous ash spewing from an Indonesian volcano, officials said.

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.

"Gooey" New Mud Volcano Erupts From Arabian Sea

There's a new island in the azure waters off Pakistan, but you might want to hold off on vacation planning: The tiny dot is a mud volcano that will likely disappear before it sees 1,001 Arabian nights.

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.

Kirishima Volcano Violently Erupts in Japan

The Kirishima Volcano, located in Japan, erupted violently this morning hurling rock bombs and plumes of ash up into the atmosphere. Frequent small-to-moderate explosive eruptions have been recorded since the 8th century.

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.


Volcano in Russian Far East continues to spew ashy plume

Kizimen Volcano
Petropavlovsk-Kamchatsky -- The active Kizimen Volcano on Russia's Kamchatka Peninsula continues spewing plumes of ash at a height of up to six kilometers (3.72 miles), a representative for the Russian Academy of Sciences' Institute of Volcanology and Seismology said on Thursday.

"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.
