Piton de la Fournaise. The massive Piton de la Fournaise on the island of Réunion is one of the world’s most active volcanoes. It is seen here in 1977 with a fresh black lava flow descending the outer NE flank of the shield volcano to the sea. An unvegetated summit lava shield (upper left) was constructed within an 8-km-wide caldera that is breached to the sea. Its sloping northern rim is marked by the diagonal vegetation line at the left. More than 150 eruptions have occurred since the 17th century, mostly from vents within the caldera. (Caption:Global Volcanism Program ).
