The Alert Level remained at Yellow. Other areas on the W side of the volcano could be affected by gas and dust clouds or by ash falls. Figure 57 is a time-series plot for Nyamuragira compiled by the MIROVA infrared processing system. Comm.). Their log said that the ". . The depths of the earthquakes ranged from 0 to 30 km, with two main areas of concentration; one between 15 and 25 km deep, and the other between 0 and 4 km. Information Contacts: Agence France Presse (AFP); Brussels Domestic News Service (DNS). Activity during 27 October-14 December 2002. . Another fracture was active on the S flank, with lava fountains and one lava flow traveling towards the SW. The eruption ended during the night of 14-15 January. Lava lake reappears in central crater in April 2018; activity tapers off during April 2019. Kampunzu A B, Lubala R T, Brousse R, Caron J P-H, Cluzel D, Lenoble L, Vellutini P J, 1984. Satellite imagery acquired on 3 January from the Advanced Land Imager (ALI) on NASA's EO-1 satellite showed an active lava flow to the NE of the central vent over the fissure located 11-12 km ENE of Nyamuragira's main crater. An Associated Press story described lava flows escaping the crater on 1 December and reaching 10 km NW that evening. of Hawai'i, 2525 Correa Road, Honolulu, HI 96822, USA (URL: http://modis.higp.hawaii.edu/); Kervyn, F, d'Oreye, N, van Overbeke, A-C, 2010, GORISK: The combined use of Ground-Based and Remote Sensing techniques as a tool for volcanic risk and health impact assessment for the Goma region (North Kivu, Democratic Republic of Congo). Heavy tephra falls occurred N, E, and S of the cone. That (720p) video shows both daylight and night scenes, features sound, and has people in the foreground, which helps establish scale. Additional information about late-December 1976 activity. Information Contacts: S. Ueki, Institute de Recherche Scientifiques Afrique Centrale (IRS). 20) became active on 14 July, producing a voluminous lava flow for the first two days, and high lava fountains that rose 50 m on 21 July. When a team from the CRSN visited the eruption site 21-25 September, a cinder cone (cone 1 on figure 8) had already reached 60 m height and lava was fountaining to as much as 180 m above the surrounding lava field. MODVOLC thermal alerts ceased after 8 April, and the MIROVA thermal data also confirmed a decrease in the strength of the thermal signal during April 2019 (figure 84). Information Contacts: Goma Volcano Observatory, Departement de Geophysique, Centre de Recherche en Sciences Naturelles, Lwiro, D.S. Toombs, A., & Wadge, G., 2012. Pressure from the ascending magma caused the ground to rise more than 50 cm at the eruptive site where a spatter cone developed. The team landed by helicopter in the summit caldera, reached the eruption site by foot, and spent 24 hours on the scene. In a report received 18 October, observers in Goma, Zaire (roughly 30 km S of the summit) described lava flows to the NW and SE [but see 17:1] and an eruption cloud rising to ~3.5 km from a site at 1.28°S, 29.22°E (on the NNE flank) [see slightly revised coordinates in 17:1]. Mt. The scoria was very vesicular and was not found in large fragments because it exploded upon striking the ground. The E wall of the cone, near the dominant vents, was about 100 m high, but the W wall was only about 30 m high. 2002 eruptions. | March. . Dario Tedesco reported SO2-rich fumaroles in Nyamuragira's central crater beginning in early March 2012, shortly before the NE-flank fissure eruptions ended (BGVN 40:01). SAR interferometry. Information Contacts: S. Peyer and H. Peyer, Gisenyi, Rwanda; H-L. Hody, GEOVAR, Kigali, Rwanda. After the initial explosion, lava was extruded from the lower end of the fissure and flowed N. Residents fled the area. Lava was ejected to 120 m above the S vent. Hirosaki: Hirosaki Univ Fac Sci, 78 p (in Japanese with English abs).
