Arenal volcano (Costa Rica): strong eruption on 25 May, National Park closed

Arenal volcano in Costa Rica had a stronger explosive and/or effusive eruption around 1pm on 25 June. According to various news sources, explosions produced 8 ash avalances (or lava flows) and promted the evacuation of parts of the Arenal National Park. Although almost constantly active during the past decades, the last major eruption of Arenal was in 1968 when 89 people got killed.

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. ... read all

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. read all
