Volcano Activity in New Zealand on Wednesday, 14 October, 2015 at 03:45 (03:45 AM) UTC.

Description Recent monitoring of White Island in the Bay of Plenty suggests a slight increase in volcanic unrest, GNS Science says. Scientists measured an increase of carbon dioxide in the gas emitted at the largest accessible steam vent on October 1. These subtle changes also coincided with the presence of volcanic tremor and more elevated amounts of sulphur dioxide gas being emitted from the volcano, a statement from GNS said this morning. This indicated that unrest at White Island might have increased slightly in recent weeks. GNS geochemists sampled the largest accessible steam vent on October 1, which indicated a small increase in the temperature to 170C and an increase in the amount of carbon dioxide gas. These are consistent with the other gas measurements made at White Island. Volcanic tremor is a common type of volcanic earthquake activity recorded on the island. Since October 8, this has been increasing in strength and become "banded". Banded tremor is common at White Island and many active volcanoes worldwide. It has been recorded during increasing unrest and a variety of eruptive periods in the past. "During visits to the island in October, GeoNet staff also sampled and measured the lake temperature (54C) and it remains similar to other recent measurements," GNS said. "However, the lake level has risen about two metres since June. Since the lake re-established in late 2013 we have measured a rise of about 6m." The Volcanic Alert Level remains at Level 1 (minor volcanic unrest). "The changes we are seeing presently are common for the island," GNS said. "Activity may continue to increase or die away. Typical volcanic unrest hazards like hot ground and gas remain. A range of activity can occur under these conditions with little or no useful warning." GNS Science is continuing to closely monitor the activity at White Island and other New Zealand volcanoes through the GeoNet project.

A team of scientists is exploring the darkest corners of a huge underwater volcano in the Caribbean in hopes of better understanding the mysteries of earthquakes and tsunamis, ultimately saving lives.
Kick'em Jenny is a dangerous and active volcano sitting roughly 6,000 feet below the surface of the Caribbean Sea, and located off the coast of the island of Grenada, south of St. Lucia.
Robert Ballard, famous for discovering the Titanic 12,000 feet below the surface of the icy North Atlantic in 1985, set his sights on exploring the Kick'em Jenny to study its eruption history and learn more about how underwater volcanoes can pose a threat.
Ballard, the president of The Ocean Exploration Trust and the director of the Center for Ocean Exploration at the University of Rhode Island’s Graduate School of Oceanography, said the Kick'em Jenny volcano has a history of explosive eruptions, which could have the potential to trigger tsunamis, the effects from which could be felt as far away as the northeastern United States.

Description The Scientific Permanent Monitoring Committee and the Peruvian have declared Ubinas volcano on orange alert, meaning that local communities have to be evacuated. The volcano, which has been active again since September last year, erupted March 31, giving off ash for one thousand meters. The 20 families living in Querapi were temporarily evacuated shortly after the eruption, but are yet to be permanently relocated to Pampas de Hawái. As well as residents of Querapi, people living in Tonohaya, also in Moquegua, and San Juan de Tarucani, Arequipa, also need to be evacuated. Civil Defense chief, Miguel Alayza said that they were waiting for the alert to go from yellow to the more serious orange before they could proceed. Regional president of Moquegua, Martín Vizcarra said that the volcanic activity would affect five thousand people in that area, while in San Juan de Tarucani, Arequipa, 637 families would be affected, according to El Comercio. Ubinas volcano is considered to be the most active volcano of Peru. Eruptions have been reported since 1550.

Peru evacuates Ubinas volcano area after ash cloud

Footage shows huge clouds of ash escaping from Ubinas

The authorities in Peru say they are evacuating people living near the Ubinas volcano, in the south of the country, because of increased activity.

Officials said it would take three days to move 4,000 residents and their livestock to safer grounds.
Ubinas, Peru's most active volcano, recently began spewing ash clouds up to 4km (two miles) high.
An eruption of cinder and toxic gases in 2006 killed livestock and forced a similar evacuation.

Volcano Eruption in Japan on Monday, 07 April, 2014 at 05:25 (05:25 AM) UTC.

Description The ongoing eruption continues to add new land to the island with what seems a relatively steady effusion of lava flows. A new overflight by the Japanese Coast Guard shows that at least the second vent that appeared in late January is still active, feeding lava flows that continue to spread and currently have active fronts all along the eastern coast. The first original vent (cone 1, right in the picture) that build the new island and grew to a nice, symmetrical cone, seems to be inactive at present. The other vent is still active and has grown a bit since the previous overflight, with a crater that emits an ash and steam plume, presumably from mild explosive activity caused by infiltrating sea water that becomes in contact with the magma. Bluish gas on the pictures shows areas where active lava flows near their vents. Landsat 8 infrared images from 30 March show that there are active flow fronts all along the eastern coast, while only 2 lobes are active towards the west.

Volcano Activity in MultiCountries on Saturday, 22 March, 2014 at 05:22 (05:22 AM) UTC.

Description

SERNAGEOMIN raised the alert level of the volcano to orange yesterday after an increase in seismic activity. A pulse of volcanic tremor was detected that could indicate magma moving into the volcano's plumbing system. On the surface, no unusual activity has been seen at the volcano so far, except that an increase in SO2 emissions (approx 2,300 tons / day) was measured. This supports the idea that magma has risen under the edifice. Whether this activity is followed by new eruptive activity remains to be seen. In most cases, intrusions of magma under volcanoes do never reach the surface, i.e. produce eruptions. ONEMI (Civil Defense) published a bulletin stating that civil alert remains at yellow for the highest risk areas, in particular the most proximal areas around the volcano itself, but also include the city of Alto Biobío located 40 km west of the volcano, because it is at the mouth of a valley that drains Copahue on the north side and therefore, a potential pathway for mud flows that could occur during an eruption.

Volcano Eruption in Indonesia on Tuesday, 11 March, 2014 at 11:06 (11:06 AM) UTC.

Description

New eruptions were observed at Java's second highest volcano since yesterday evening. A series of explosions produced ash plumes rising 800-1000 m above the summit, the local observatory reported. This activity came after a steep increase in volcanic earthquakes from averages of approx 50 to more than 200 per day, volcanologist Mr Sudrajat from the local observatory told the press. The first explosion occurred Monday evening at 20:06, causing the glass windows of the observatory building to vibrate. Shortly after, the Center for Volcanology and Geological Hazard Mitigation (PVMBG) raised the status of Mount Slamet from normal to alert (2 on a scale of 1-4). According to local press, the vibration from the eruption could be felt in up to 10 km distance and described the plume as "thick smoke". Slamet is one of Java's most active volcanoes and often has strombolian to vulcanian-type activity in its summit crater.

Volcano Hiking Routes Closed as Mount Slamet Put on Alert in Central Java

By Jakarta Globe on 01:32 pm Mar 11, 2014

Jakarta/Purbalingga. Indonesia’s geological agency sounded an alert for the Central Java volcano Mount Slamet on Tuesday, advising hikers to avoid the crater rim but falling short of instructing local communities to evacuate.
“It started on Monday evening at 9 p.m,” said Sutopo Purwo Nugroho, head of the National Disaster Response Agency (BNPB), in a text message sent on Tuesday.
The Center of Volcanic and Geological Disaster Mitigation (PVMBG) raised the status of Mount Slamet in Central Java activity to the second level of alert: waspada.
Sutopo said volcanic activity was a potential risk for five sub-districts located around Mount Slamet: Banyumas, Brebes, Pembalang, Purbalingga and Tegal.
The PVMBG has recorded 441 minor quakes and 9 shallow volcanic quakes since March 8.
“We suggest residents stay calm and not panic,” Sutopo said. ”We also recommend tourists, hikers and residents do not to hike the mountain or do anything within the two-kilometer radius of Mount Slamet’s crater.”
The Regional Disaster Mitigation Agency (BPBD) has not warned residents directly.
“We have not officially warned the people living in around Mount Slamet, especially the ones in Purbalingga sub-district, like Kutabawa village, Karangreja ward, and others,” Purbalingga BPBD chief Priyo Satmoko said on Tueday.
