View westward along the Kapoho fault scarp in the village of Kapoho following a swarm of earthquakes in the area. The ground cracking was caused by subsidence of a graben (down-dropped block) that spanned the community. The subsidence accompanied the rise of magma along this part of the East Rift Zone, which erupted a few hours later less than about 600 m (1,970 ft) from
