Le 20 mars les modèles de séismicité et des émissions du cône MacKenney du Pacaya ont changé, bien que la caractéristique soit restée à un comportement normal pour le volcan. Le 26 mars des avalanches ont été détectées et pendant le 26-27 mars des panaches de gaz ont dérivé vers le S et SO. Le rapport a noté qu'après l'éruption du 27 mai 2010, il y a eu seulement des émissions fumerolliennes, principalement composées de vapeur d'eau, qui se sont émanées du cône MacKenney. ...plus [lire toutes]

Following the violent eruption on 28 May, a large 90-m-wide lava flow was emitted on 29 May that traveled SSE at an estimated rate of 100 m per hour and burned three houses on the Pacaya Grande ranch. The lava was within 450 m of some other properties including El Chupadero, located 2-2.5 km S of the crater, and disrupted an access road from El Caracol (3 km SW) and Los Pocitos (5.5 km S). ...plus [lire toutes]

Au cours de la période du 6-19 Février des émissions de panaches fumerolliens de couleurs blanc et bleu issu du cône Mackenney du Pacaya ont atteint une altitude de 2.6-2.7 km, et ont dérivé vers le S, SW, et W. Deux à cinq coulées de lave par jour ont parcouru environ 50-200 m à l'Ouest et NW et rempli l'espace entre le cône Mackenney et le cratère Cerro Chino au N. ...plus [lire toutes]

24 January: White and blue fumarolic plumes were drifting from Pacaya's MacKenney cone to S and SW. Four lava flows traveled about 100 m to the W. The Alert Level was lowered to Green. [lire toutes]

Mild strombolian activity and the effusion of two small lava flows continue at Pacaya volcano. New small lava flows ca. 150 and 300 m long are present on the upper NE flank, travelling NE and N towards Los Llanos y Cerro Chino. [lire toutes]samedi, juin 16, 2007
Strombolian activity continues at Pacaya from two vents at the summit crater. Incandescent projections reach 200 m height. A lava flow descends on the NE flank. ...plus [lire toutes]

INSIVUMEH reported that on 31 May, and 1 and 5 June, lava from the NE flank of Pacaya's Mac Kenney Cone continued to flow and pooled between the base of the volcano and the plateau. Gas plumes from the summit drifted N and SW and rose to altitudes of 2.8 km (9,200 ft) a.s.l. on 5 June. Small pyroclastic explosions from the N part of Mac Kenney Cone were occasionally observed.

INSIVUMEH reported that on 9 and 12 March, fumurolic activity from Pacaya's MacKenney Cone produced plumes that rose to 3 km (9,800 ft) a.s.l. and drifted S and SW. Incandescence was reflected in the plumes on 9 March. A lava flow from a crater on the NE flank was visible on 12 and 13 March to distances of 300 m. ...plus [lire toutes]

Pacaya volcano remains active producing a lava flow that travels, partly in a 0.5-1.5 m wide tube, about 500 m down the NNE flank of the summit cone. White steam and gas plumes are rising about 300 m ober the summit. ...plus [lire toutes]samedi, avril 08, 2006

Pacaya continues its slumber. Only a weak steam plume of about 150 m height is visible above its crater. [lire toutes]mardi, juin 21, 2005
Between 16-18 June, strombolian activity had been more vigorous, sending incandescent blocks to up to 150 m height and destroying parts of the intra-crater cones around the vents.
On June 20, two lava flows descended yesterday from the central crater and have reached 150 and 200 m length. Small strombolian explosions continue from the crater. [lire toutes]

The two lava flows from the central crater cone to the SW and W are still active, with fronts of about 200 and 300 m width near the saddle of Cerro Chino. Weak strombolian activity continues to be present at the summit crater. [lire toutes]

Strombolian explosions have paused since yesterday, while small quantities of white steam are still being emitted. Two lava flows, about 2-300 m long, are still active and flowing down in parallel channels at the WSW base of the intra-crater cone. Blocks detach from the flow front and arrive at the saddle between Cerro Chino and Pacaya. ...plus [lire toutes]jeudi, mai 26, 2005
