Piton de la Fournaise (La Réunion): The eruption that had begun more than a month ago (in the evening of 9 April) still continues with moderate lava effusion, making this eruption one of the longer-lasting ones at the volcano in recent years.
Magma erupts from the two vents on the original eruptive fissure, where small cones have formed. The latest measurements show that the larger of the two cones now has a width of 226 m and a height of around 35 m. Mild strombolian activity and spattering is occurring at the cones having open craters, with some lava ejected to the immediate surroundings, but most of the lava is diverted directly into underground tubes and flows to the active surface flows with fronts at about 5-6 km distance downslope.
