Santiaguito is the name of the dome complex that grew inside the collapse scar left by the catastrophic eruption and partial collapse of Santa María stratovolcano in 1902. Its currently active dome is called Caliente (the "hot one").
Symmetrical, forest-covered Santa María volcano is one of the most prominent of a chain of large volcanoes that rises dramatically above the Pacific coastal plain of Guatemala. Santa Maria erupted catastrophically in 1902 destroying its former summit.
Santa Maria is a popular excursion destination and the summit offers spectacular views onto erupting Santiaguito.

Pyroclastic flow and phoenix cloud from Santiaguito volcano on 15 September (image: INSIVUMEH) The activity of the volcano has remained essentially unchanged at elevated levels during the previous months characterized by pyroclastic flows and new period of extrusion of the dome blocks. ...màsINSIVUMEH reported that extrusion of the dome blocks is appeared reaching over the edge of the crater of the Caliente dome and causes block-and-ash flows that continue to descend over the western and southwestern slopes, sometimes phoenix clouds are formed. The length of the flows is about 800 m. Accumulating of the volcanic material in the lower part and on the west and southwest flank of the Caliente dome can lead to formation of lava flows or moderate to strong lahars (mud flows) towards the San Isidro river channel. A weak to moderate explosions at regular intervals of 15 to 20 per day are generated which reached approx. 9,842 ft-10,826 ft (3,000-3,300 m) altitude and extending about 10-12 km of the volcano.

Incandescent avalanches from Santiaguito volcano on 20 August (image: INSIVUMEH) INSIVUMEH reported that incandescence avalanches continue to be observed in the Caliente dome and caused avalanches of material in S-SE-SW direction that reached the base of the dome. ...màsA weak to moderate explosions are generated which reached approx. 10,826-11,811 ft (3,300-3,600 m) altitude and extending about 10-12 km of the volcano. Seismicity remained elevated including periods of high amplitude tremor. [ Menos]

Pyroclastic flow from Santiaguito volcano (image: INSIVUMEH) The activity of the volcano continues at elevated levels during the past two months. ...màsAccording to INSIVUMEH the volcano entered to a new period of activity associated with lava extrusion of dome blocks which continue to descend on the west, east and northeast slopes. It produces frequent pyroclastic flows that travel over the slopes, as can be seen in the webcam screenshot. Incandescence of the dome blocks is visible from the crater and caused hot avalanches of material on the S, SW and SE flanks.

Explosion from Santiaguito volcano yesterday (image: @insivumehgt/twitter) INSIVUMEH recorded a white fumarole in Caliente dome that rose 9,842 ft (3,000 m) above the summit. ...màsSurveillance cameras observed small to moderate explosions that generated a plume of ash that rose to an altitude of 10,498 ft (3,200 m) and drifted S-SW. Material is ejected above the crater and caused weak avalanches of material on the south, southeast and southwest flanks of the Caliente dome. [ Menos] lun, 11 may 2020, 01:49

INSIVUMEH report continued degassing plume expulsion reaching heights of around 3300 m.a.s.l. that drifted southwest over the villages of Loma Linda and San Marcos Palajunoj. The STG3 seismic station recorded mostly weak explosions, where some generated airplane turbine sounds. On the southern, eastern and southeastern flanks, the activity was generally block avalanches.
