Mount Nyamulagira Erupting, Again?

Posted by feww on January 3, 2010

Mount Nyamulagira in DR Congo erupted

Lava from Mount Nyamulagira Saturday eruption sent lava into the surrounding Virunga National Park, BBC reported.


Photo released by the Congolese Wildlife Authority, Virunga National Park, shows Nyamulagira erupting early Saturday local time on January 2, 2010.

Mount Nyamuragira, Africa’s most active volcano, is located about 25km (16 miles) north of Goma. A large section of the city of Goma (population of 200,000 plus at least 100,000 war refugees), located in the east of the country was destroyed in 2002 after  Mount Nyiragongo erupted.

Lava spewed along the volcano’s southern flank into Virunga National Park, but avoided the nearby villages. there were no casualties reported. However, about 4 dozen endangered chimpanzees as well as other animals live near the volcano.

One of Virunga’s wardens told reporters: “I saw the mountain was on fire with sparks flying.”

Nyamulagira has erupted about 40 times since the late 19th century.


Following a loud explosion at 03:45 local time (01:45 UTC) Lava from Nyamuragira flowed along the volcano’s southern section incinerating everything on its path. Freeze frame from CCTV. Image may be subject to copyright.

FEWW Comment: If we are looking at a sulfur dioxide dispersal scenario in relation to the Earth’s defense mechanism against Warming, then the latest eruption could have been just an opening salvo in the upcoming eruptions of Nyamulagira and its neighbor Nyiragongo volcano.

Major Volcanoes of the DR Congo

In May 2009 Scientists in the DR Congo recorded a significant increase in volcanic activity around the city of Goma.

Lava fountains from the new cone of Mikombe on the lower NE flank of Zaire’s Nyamuragira volcano feed the lava flow in the foreground. This photo was taken from the SE on September 29, nine days after the start of the eruption. During the first week the new cone, whose name means “many bats,” grew to a height of 60-70 m. Lava flows had traveled 6-7 km NE by the time of this photo. The eruption continued until February 1993, by which time lava flows had traveled 19 km to the NE.

The summit of Nyamuragira volcano is truncated by 2 x 2.3 km wide caldera whose floor is partially covered by unvegetated historical lava flows. This view from above the SW caldera rim shows a pit crater on the far side of the caldera at the upper left that was the site of a lava lake, active since at least 1921, which drained in 1938 at the time of a major flank eruption. Africa’s most active volcano, 3058-m-high Nyamuragira rises about 25 km north of Lake Kivu in the East African Rift Valley NW of Nyiragongo volcano.  Photo by Simon Carn, 2004 (TOMS Volcanic Emissions Group, University of Maryland, Baltimore County).

Africa’s most active volcano, Nyamuragira is a massive basaltic shield volcano that rises north of Lake Kivu across a broad valley northwest of Nyiragongo volcano. The volcano has a volume of 500 cubic kilometers and extensive lava flows from Nyamuragira cover 1500 square kilometers of the East African Rift. The 3058-meter-high summit is truncated by a small 2 x 2.3 kilometer summit caldera that has walls up to about 100 meters high. Historical eruptions have occurred within the summit caldera, frequently modifying the morphology of the caldera floor, as well as from the numerous fissures and cinder cones on the volcano’s flanks. A lava lake in the summit crater, active since at least 1921, drained in 1938. Twentieth-century lava flows extend down the flanks more than 30 km from the summit, reaching as far as Lake Kivu.

SO2 emissions from Mount Nyamulagira’s previous eruption on November 27, 2006


The Ozone Monitoring Instrument on NASA’s Aura satellite tracked the emission of SO2 gas from the volcano between November 28 and December 4, 2006. The sulfur dioxide concentrations are shown here using a logarithmic color scale. (The value at the top of the scale is about 149 times greater than the value at the bottom.) Credit: NASA.

Honduras

Dozens of people have been killed among 270,000 Hondurans who have been affected by severe flooding and landslides caused by heavy rains, and at least 20,000 others have been forced to flee their homes for shelters. Half of those affected are children. UNICEF

The Permanent Commission for Contingencies (COPECO) has reported

  • 33 deaths were reported a
  • 42,234 persons evacuated
  • 467 houses were destroyed
  • 10,000 homes are flooded or damaged.
  • About 100,000 hectares of crops have been lost.
  • Approximately 50% of the roads are damaged or destroyed.
  • Some 114 out of 298 municipalities are affected.
  • Public health is an area of concerns even though no outbreaks have been reported.
  • PAHO/WHO reports that 14 potable water systems are damaged.
  • Currently no severe food security issues, but the next production will be affected.

The main health concerns are gastrointestinal diseases and acute respiratory infections. Primary needs include portable latrines, water purification and household hygiene kits.

Guatemala, Nicaragua, El Salvador, Costa Rica and Belize

Up to 100,000 people have also been affected by the flooding in the neighboring Central American countries of Guatemala, Nicaragua, El Salvador, Costa Rica and Belize.

Haiti and Cuba

Two of the countries most impacted by the devastating 2008 hurricane season so far effects on are Haiti and Cuba. Widespread crop damage due to the numerous storms has aggravated the effects of the global food crisis, raising concerns about nutrition for children and pregnant/breastfeeding mothers. UNICEF

Kenya

As the drought worsens due to the generally poor long rains this year food security deteriorates in kenya. The worst affected areas include Turkana, Mandera, Samburu, Baringo, Marsabit, Wajir, Moyale and Garissa districts. Also affected are the districts of Isiolo, Laikipia, Ijara, Taita Taveta, Kitui, Mwingi, Makueni, Mbeere, Malindi, Kilifi, Kwale, and Tana River districts. Source: Office of the President

DR Congo

Tens of thousands of civilians are fleeing from the areas of Tongo, Kalengera, Kabiza and Rumangabo, in the North Kivu province (east Democratic Republic of Congo), where new fighting broke out Friday between the Congolese military and rebels of the renegade pro-Rwandan general Laurent Nkunda.

Bangladesh

Several people have been killed, and dozens injured as tropical storm Rashmi struck southern Bangladesh damaging thousands of homes, uprooting trees and destroying vast areas of croplands. Further details of certain damage to coastal areas are not yet available.

Cyclone Sidr destroyed the coastal areas last November, killing up to 3,500 and displacing about two million people. (Reuters)

Pakistan

More than 15 per cent of the children, living in the camps set up by the government for the internally displaced persons (IDPs) of Bajaur tribal region, are suffering from malnutrition. (source: DG Newspapers)

Meanwhile, a strong magnitude 6.4 earthquake centered about 60 km (35 miles) NNE of Quetta, Pakistan, 640 km (400 miles) WSW of the capital, Islamabad, struck at 04:09:58 am local time, on October 29, 2008, killing at least 135 people, injuring hundreds more, making about 15,000 homeless.
