The eruption has built 23 cinder cones along a 2.5-km zone that trends generally NE, ~15 km NE of Nyamuragira caldera and 5 km ENE of the 1957 Kitsimbanyi vent (figure 12 and table 1). The most active volcano in Africa, Nyamulagira often emits lava and ash, though fatalities are rare. Subduction Zones and Volcanoes At some convergent boundaries, an oceanic plate collides with a continental plate. Eventually all of the underlying plate will be consumed, and the subduction zone will encounter the far side of the plate, which may have another subduction zone with an island arc, or possibly a continent. Satellite images showed hotspots at Nyamuragira volcano in early 2017, indicating ongoing eruptions. Money from visitors is used for developing and protecting the park. Lava could cover the Goma and Sake road within weeks. +243 971 327 207 Such hazards include shaking by large earthquakes in subduction zones, where one tectonic plate compresses another (Cascadia, Aleutian Trench); or on strike-slip faults, where one tectonic plate moves horizontally past another (central and southern California).
