Final answer:
C. Congo, where Mount Nyiragongo is located in the Great Rift Valley region, and its 2002 eruption devastated the area. The volcano is still active and poses significant risk to nearby communities.
Step-by-step explanation:
C. Congo. In 2002, Mount Nyiragongo erupted, causing significant destruction in the Democratic Republic of Congo. This volcano is known for having one of the world's largest lava lakes, and it is situated in the Virunga National Park, in the eastern part of the country, near the border with Rwanda.
Considering the broader context, the African Great Rift Valley region, which encompasses Mount Nyiragongo, is characterized by high volcanic and seismic activity. This is due in part to the rifting process where the African continental plate is splitting into two parts, leading to the formation of various volcanic features, including Mount Nyiragongo.
The tragic events of the 2002 eruption demonstrate the formidable impact natural disasters can have on human populations, particularly in densely populated areas near volcanoes. Since then, Mount Nyiragongo has continued to be an area of concern due to the potential risks it poses to the surrounding communities, including the major city of Goma, which lies in its shadow.
