In some cases additional feature type, elevation, or location details are provided. Karisimbi, the highest of the Virunga volcanoes, is a complex basanitic-to-trachytic volcano with a symmetrical sharp-peaked summit.
The 2-km-wide Branca caldera, located SE of the summit, is filled by viscous lava flows and two explosion craters. The large 1. A broad lava plain, formed from lava flows erupted within the caldera and along a chain of parasitic cones, extends SW.
The youngest Potassium-Argon date obtained is about 10, years before present de Mulder, The youngest eruptions produced a group of dome-shaped parasitic vents east of the caldera, which fed viscous lava flows that traveled as far as 12 km E, and lava flows from the SW-flank satellitic lava vents.

Date and type of imagery is unknown. Mudflows are not readily apparent in the image either because of issues such as cloud cover and resolution or most likely because the image was collected prior to the event.
Note that international boundary lines often are drawn imperfectly on many satellite images and are unconfirmed here. Courtesy of OCHA. Figure 2. Map showing the various branches of mudflows found to the W of Karisimbi volcano on 16 May Satellite data revealed that the flows were more complex than the three branches originally reported based on field observations.
Figure 3. Volcanic rocks on the order of decimeters were carried by the mudflows in some areas near Karisimbi volcano on 16 May Figure 4. Mud flowed through homes in Kibiriga village near Karisimbi on 16 May Because of the high speed and because the flow occurred at night, many residents could not escape.

The event caused human casualties and destroyed 7 hectares of crops. Information is preliminary and subject to change.

The threats of poaching are also likely to increase. To proactively address these pending threats, the International Gorilla Conservation Program IGCP - a joint initiative of AWF, Fauna and Flora International and the World Wildlife Fund - is coordinating with the agencies delivering food aid and shelter to people in the region, to ensure that the park does not become the source of these items.
