columns of ash that deposits a layer of 2.5 cm of fine slag in El Caracol. Eruptive column up to almost 1,700 meters in height. Losses of almost Q. 70,000 for damage to crops of coffee, maize, beans, and repayment of livestock evacuated to other pastures (MAGA
data). Air navigation detects ash at 18,000 feet.

flows to the WNW, north and south towards the hamlet El Caracol. Column of ash of almost 5 kms of height.
December 11: Explosions with expulsion of incandescent material
up to 25 m above the active crater.
2000: January 6: Eruption with incandescent source. Lava flow to SW accompanied by fiery clouds reaching
the base of the cone. Deposition of basaltic slag to almost 7 km of distance and ash in Escuintla. Due to a dark cloud of very fine ash, visibility and traffic on a section of the CA-2 Highway between Tiquisate and Patulul (Suchitepequez) is difficult. Due
to falling slag evacuation of 1168 people from the populations of the Rodeo, El Caracol, El Patrocinio.

April: After the eruption of the year 2000, the Pacaya Volcano maintained a period of generation of water vapor and sulfur dioxide, manifested by a light colored column emanating from the volcano's active crater occasionally reaching almost one kilometer
High above the crater.
2005: Incandescence in the crater product of magma within the same to a depth of 30 meters, emanation of fumarola (gases).
2006: February 02: Generation of mesh-like cracks associated with the ascent of magma trapped in the volcanic building, located mainly on the east, north
and west flanks, causing deflation in the north flank.
March 14: Start of eruptive phase on the northern flank. Stack of lava flows that filled the plateau. The effusive
activity generated cracks.
May: Total filling of the plateau.
The constant effusion of lava filled the plateau from the east to the south with important stacks of lava by the flanks of the volcano.
2010: May 13:
Increase in seismic activity. Close up of Pacaya National Park.

moving to the south, then to the west and later to the north. Closure of the international airport "La Aurora". Incandescent sources that reached 3000 m in height. Collapse of the western edge of the Mackenney cone. Ballistic material and thick columns of
ash affected the communities of San Francisco de Sales, Calderas, El Bejucal, Mesillas alta and Bajas, the continuous ash column advancing affecting populations such as Amatitlán, Villa Nueva, Santa Elena Barillas, Boca del Monte and finally 1000 kilometers
to the north. Ballistic and ash caused the collapse of more than 800 houses, some injured and the death of a journalist
May 28: eruption with columns of ash in the direction of the north
flank of the volcano affecting Guatemala City.
May 29: Effusive eruption on the southeast flank of the volcanic building through a fissure is formed a conict with lava flow
that reaches 6 kilometers in length. Threat to the Pocitos and Dolores communities. The Mackenney crater was left with an opening of 70 m of diameter by 50 m of depth, besides until.
ash expulsions that at times exceed the 10 km of displacement.
2014: January: Eruption with incandescent source 3000 msnm, flows of lava of
4 kilometers of length in south direction.
March: Strombolian eruption, extensive ash feather of 5000 msnm. It moved 240 kilometers arriving in Mexican territory, ash fall
is reported throughout the southern coast. Lava flows to the southwest, affecting avocado and coffee crops in this area.
2016> At the present
time inside the crater of the Mackenney cone is observed the growth of small cones that to this date are still observed.
