Several explosions and the occurrence of tectonic earthquake at Nyamuragira
may reveal the renewal of activity.

On the 26th, an increase in long-period and tectonic earthquakes as well as
tremor amplitude was recorded. Spasmodic tremor on the 19th and 23rd lasted
several minutes and scientists stated that an eruption may occur relatively
soon.

The eruption that in July appears to be over; only fumarolic activity and weak
tremors are recorded.

The eruption that began on July 25th continued this week. Two volcanic cones were built by the accumulation of ejectas from two 100- to 200-meter high lava fountains. These cones grew on the eruptive fracture. The main NNE flow produced by the eruption was estimated to be 15 kilometers long. On August 6th, the eruption moved to the lowest part of a fracture on the northern flank. Three more lava fountains reaching a height of about 100 meters were observed.

On the evening of July 25th an eruption produced 100 to 200-m high lava fountains and lava flows down the north and south flanks of the volcano.

On 6 February, the Nyamuragira volcano began erupting, and observers were able to view active lava flows originating from two fissures. Nyamuragira is Africa's most active volcano.

On 26 January, the Nyamuragira volcano, straddling Rwanda's border with eastern Congo, sprang to life and started spewing lava ejecta. The volcano erupted on 29 January and continued to erupt intermittently over the weekend. The present eruption site is estimated to be in close proximity to the large fissure with a direction NW-SE crossing the southeastern rim of the Nyamuragira crater. The volcano is located 50 km NW of the rebel stronghold of Goma, and many residents first thought the area was under an artillery attack. Although the lava has flowed toward the unpopulated side of the mountain and the Virunga National Park, two nearby communities have been evacuated as a precautionary measure.
This information was summarized from Discovery Online and Global Volcanism Program.
Nyamuragira has been producing lava flows from its cone and from a fissure on its flank since October 17. It is still very active, although the lava flows appear to be slowing down. This is the first time this volcano has produced flows since December 1996. Goma, the nearest town to the volcano, is the headquarters of rebels who are currently revolting against President Laurent Kabila. Clashes between these rebels and Rwanda Hutu militia in this area make it extremely dangerous for anyone to approach the area. This has made monitoring this eruption nearly impossible.
