Based on observations from satellites, webcams, pilots, and the Vanuatu Geohazards Observatory (local community reports), the Wellington VAAC reported that during 11-14 April ash plumes from the vent at Ambae?s Lake Voui rose to altitudes of 1.8-4.9 km (6,000-16,000 ft) a.s.l. and drifted N, NW, W, and SE. On 12 April news articles noted that ashfall had affected the N part of Ambae, with photos showing thick ashfall deposits on houses and agricultural land, and reports of contaminated water supplies. On 15 April a VAAC office reported that the eruption has ceased. The Alert Level remained at 3 (on a scale of 0-5).

- Fuego (Guatemala) - Report for 11 April-17 April 2018
INSIVUMEH reported that on 9 April a lahar descended the Seca (Santa Teresa) drainage on Fuego?s W flank. The lahar was 10 m wide, 1.5 m deep, and had a consistency similar to cement mix. During 12-13 April explosions generated ash plumes that rose as high as 1 km and drifted 15 km SW and W. Incandescent material was ejected as high as 300 m above the crater rim, and generated avalanches of material in the Seca, Cenizas (SSW), Las Lajas (SE), and Honda (E) ravines. Ash fell in areas downwind including in Santa Sofía (12 km SW), Morelia (9 km SW), Panimaché (8 km SW), (SSW), Las Lajas (SE), and Honda (E) ravines. Ash fell in areas downwind including in Santa Sofía (12 km SW), Morelia (9 km SW), Panimaché (8 km SW), El Porvenir (8 km ENE), and Finca Palo Verde. Activity increased on 14 April and remained elevated through 17 April. Moderate-to-strong explosions were detected at a rate of 6-9 per hour, and sometimes produced shock waves that vibrated houses in Morelia and Panimaché. Dense ash plumes rose as high as 1.1 km and drifted 20 km W and S, though winds also carried the ash to higher altitudes to the SE. Incandescent material was ejected as high as 300 m above the crater rim, and generated avalanches of material in the crater area. Ashfall was reported in areas downwind including in Santa Sofía, Morelia, Panimaché I and II, El Porvenir, and Finca Palo Verde. The rate of explosions increased to 7-10 per hour on 16 April; explosions sometimes caused structures in Panimache, Morelia, La Reina, and Alotenango (8 km ENE) to vibrate. A lava flow traveled 1.3 km down the Seca drainage.
