Volcano news: Arenal volcano, Costa Rica

Arenal volcano (Costa Rica), activity update: continuing sporadic explosions, small lava flows

Arenal volcano continues to be mildly active. Over the past weeks, activity at crater C consisted of gas emissions, sporadic Strombolian eruptions, lava flows traveling down the SW and S flanks, and occasional avalanches from lava-flow fronts. Blocks from the lava-flow fronts periodically reached vegetation and started small fires. Acid rain and small amounts of ejected pyroclastic material affected the NE and SE flanks. Eruptions produced ash plumes that rose about 2.2 km (7,100 ft) a.s.l. Pyroclastic cones on the NE and SW flanks continued to grow. Small avalanches of volcanic material traveled down several ravines. Crater D showed only fumarolic activity.

In February, activity originating from Arenal's Crater C consisted of gas emissions, sporadic Strombolian eruptions, lava flows traveling N, and occasional avalanches from lava-flow fronts. Blocks from the lava-flow fronts traveled N, NE, and NW, periodically reaching vegetation where they started small fires. Volcanic activity was at relatively low levels, however, with few eruptions occurring and a small amount of pyroclastic material ejected. Eruptions produced ash plumes that rose about 2.2 km (7,100 ft) a.s.l. Ash and acid rain fell on the NE and SE flanks. Small avalanches of volcanic material traveled down several ravines. Crater D showed only fumarolic activity. lire toutes

Arenal volcano is getting more active again. After growing lava flows on the volcano's southwestern flank during the previous months, moderate explosive activity started on 2 November at 14h54 local time. A pyroclastic flow was generated at 15h02 lasting for about 10 minutes and travelling down the volcano's western flank. An associated ash plume drifted southeast. The pyroclastic flow occurred in an area currently closed to visitors. lire toutes
