During 19-26 April, there were several emissions of gas, steam, and ash. The highest rising ash cloud reached 800 m above the volcano and visual observations suggested that rockfalls probably accompanied the eruption. Seismicity decreased slightly during the report period; there were earthquakes with magnitudes less than or equal to 2.0 at depths of 0-5 km, many local shallow seismic signals (from possible avalanches or weak gas-and-ash explosions), and intermittent episodes of weak volcanic tremor.

The Darwin VAAC stated on 24 April that reports of an eruption at Lamington on 22 April were false. Based on information from Geoscience Australia and satellite imagery, the Darwin VAAC originally reported that an E-drifting ash cloud from Lamington seemed to be evident on satellite imagery on 22 April at 1741. Thunderstorms near the volcano made it difficult to locate possible ash on satellite imagery. Read all- More about Lamington volcano

During 12-19 April, the level of volcanism at Soufrière Hills slightly decreased in comparison to the previous week. Lava-dome growth was concentrated on the SE area of the dome complex, although small rockfalls occurred in other areas. The lava dome evolved from a large striated lobe at the beginning of the week, to a series of small spines by week's end. Read all- More about Soufriere Hills volcano
