The northern fissure vent (CONRED)
The ongoing eruption of the volcano involved the opening of at least two effusive fissure vents on the northern and southern base of the Mackenney cone (this info according to images and maps published by CONRED, although CONRED / INSIVUMEH at the same time report 3 vents on the east, west and south flank).

These fissures feed two large (and possibly one smaller third) lava flows that have reached lengths of 3-5 km length and are several hundred meters wide at their fronts (up to 800 m on the western side). The lava flows have burned extensive areas of farmland and woods and are close to some villages.
In the meantime, moderate to violent strombolian activity continues at the summit.
CONRED declared orange civil alert and started to evacuate families living in areas close to the volcano.
The lava flow from on the north side started from an eruptive fissure at approx 2250 m elevation on the flank of the cone, traveled north towards the caldera rampart of Cerro Chino and then turned left - west - when meeting the topographic obstacle. It is now close (less than 1 km) from the village El Patroncino and has a 500-800 m wide front.
On the southern side, a vent opened low at the base of the cone, at approx. 1880 m elevation, and started to feed a lava 200 m wide lava flow that seems to have reached about 5 km length near the Rincon de Pacaya area (part of Los Pocitos) on the SSW side.
At the moment, a decreasing tendency of tremor and activity is visible.

A strong increase in activity began last night at the volcano. Accompanied by steeply rising tremor, the so-far mild strombolian activity picked up to become intense enough to produce pulsating lava fountains that eject glowing material to several hundred meters height and is visible from tens of kilometers distance (e.g. the Pacific coast at 50 km to the west). ...

Mild strombolian activity continues with little changes. Incandescent ejections can be seen from the capital on clear nights. [more]

Mild stombolian activity with ejections to 10-50 m height above the new cone inside Mackenney crater continue at intervals of approx. 30 seconds. [more]
