A local seismometer recorded over 700 earthquakes per day in comparison to 100 earthquakes per day recorded approximately 2 weeks earlier. SO2 gas emissions increased from 253 tons/day to 550 tons/day. In addition, lava was visible in the summit region at MacKenny Crater.

Satellite imagery showed possible low-level ash near the volcano's summit. Source: Washington VAAC -------------------------------------------------------------------------------- 12-18 June 2002 The Washington VAAC reported that on 17 June at 0815 satellite imagery showed a very thin SW-drifting plume of unknown composition emitted from Pacaya. In addition, satellite imagery showed a faint hotspot at the volcano's summit.

By 1430 the plume was no longer visible, possibly obscured by thunderstorm clouds in the area, and the Guatemala Volcano Observatory reported that only steam was emitted from Pacaya.

White plumes rose to heights 500-700 m from the central crater.

Weak glow was visible from MacKenney cone, variable tremor was recorded, and white plumes rose to ~200 m above the crater.
