Pacaya erupted between 0630 and 0700 on 1 June 1995, sending up a 6-km-high plume. Hot ash burned vegetation and damaged radio-antenna equipment near the summit. A thin layer of ash extended as far as 2 miles (3.5 km) away from the vent, with ashfall reported 2.5 km N in San Francisco de Sales and 3.5 km W in El Patrocinio. Analysis of the eruption using GOES-8 satellite images revealed a plume moving to the southeast at 12 miles/hr (19 km/hr). The plume rose to a height of 5.6 miles (9 km). A plume visible at 0715 on GOES-8 satellite images was moving SE at ~19 km/hr, prompting a NOAA Volcano Hazard Alert at 1000. Analysis based on comparison of wind shear data and observed translation of the plume suggested that the plume rose to ~9 km altitude. Eddie Sanchez noted that venting ash destroyed the 1984 spatter cone (SEAN 10:03), called El Hornito, located roughly midway between the N caldera rim (Cerro Chino) and the previously active MacKenney cone. In place of El Hornito was a small crater venting lava, a substantial amount of which flowed south.



Pacaya is 18 miles (30 km) south of Guatemala City, the capital of Guatemala. Pacaya is a stratovolcano that has erupted at least 20 times since 1565. Since 1965, the volcano has been erupting almost continuously with pauses between eruptions lasting only a few months. Recent eruptions produced a 2.8-mile (4.5 km) tall Strombolian eruption column in 1989 and lava flows in 1989-91.



Eruptions from Pacaya, one of Guatemala's most active volcanoes, are frequently visible from Guatemala City, the nation's capital. Pacaya is a complex basaltic volcano constructed just outside the southern topographic rim of the 14 x 16 km Pleistocene AmatitlÓn caldera. A cluster of dacitic lava domes occupies the southern caldera floor.
