On 25 April the Vanuatu Meteorology and Geohazards Department (VMGD) reported that activity at Yasur continued at a level of “major unrest,” as defined by the Alert Level 2 status (on a scale of 0-5). Recent visual observations and photos taken in the field indicated that explosions continued, producing emissions of gas, steam, and/or ash. Gas emissions were identified in satellite images during the previous few days.

Wed, 1 May 2024, 14:00IMO reported that the cone just E of Sundhnúk and along the fissure within the Reykanes volcanic system continued to erupt lava. The average effusion rate was .9 (± .4) cubic meters per second during 15-25 April, whereas during the first half of April the rate was an estimated 3-4 cubic meters per second. By 25 April the lava-flow field was an estimated 6.16 square kilometers with an approximate volume of 34 (± 1.9) million cubic meters.

IG-EPN reported that a moderate eruption at Reventador was ongoing during 23-30 April. Seismicity was unknown due to data transmission problems. Even though cloudy weather conditions often prevented webcam and satellite observations, daily ash-and-gas plumes were visible rising as high as 1.4 km above the crater rim and drifting NW, W, and SW.

On 18 April INETER reported that there continued to be no signs of lava-lake activity at the bottom of Masaya's Santiago Crater after material from a landslide had covered the lake on 2 March. Small landslides continued to occur periodically, and one was shown in a webcam photo from 17 April. Continuous diffuse gas emissions rose from a vent on the crater floor and from a new vent located on the inner SW wall.

PHIVOLCS issued a special notice for Kanlaon at 1530 on 30 April noting increased sulfur dioxide emissions. On 30 April a Flyspec instrument measured an average of 2,707 tonnes per day (t/d) of sulfur dioxide emissions at the summit crater, the second highest value recorded in 2024; sulfur dioxide emissions average 3,098 t/d on 19 January. The report noted that higher sulfur dioxide gas fluxes had been recorded for a year with an overall average of 1,300 t/d.
