Santa Maria and the steaming Santiaguito volcanoes.
The scores on the cards are based on what we know about the past and continuing activity of Santa Maria. Elevation m: Like this: The bulk of the domes were built by the extrusion of lava flows and spines, but the dacite lava is so viscous that it poses no immediate hazard on eruption.

The dome complex has since grown to include four domes totaling more than 1 km3 0. Bimodal soda-rich calc-alkalic stratovolcano.
Rose 1973 described the evolution of Santiaguito. Name required.Top 10 Deadliest Volcanic Eruptions in History
From 1922 to 1972 there were four periods of rapid extrusion separated by periods of little magma production. Santiaguito bottom left , Santa Maria, and the town of Quezaltenango top.
The massive dacitic Santiaguito lava - dome complex has been growing at the base of the 1902 crater since 1922.
Explosions were heard in Costa Rica 850 km south of the volcano. Santiaquito dome complex as viewed from above and just north of the dome, so that the north face is observed.
For this reason, its unpredictability score is quite high. The final report of the workshop is available by clicking here.

From 1972-1975, both Caliente and El Brujo the domes on either end of the complex were active at the same time, producing lava flows, pyroclastic flows, and ash-and-gas eruptions. On the 4th January there were three explosions which produced an ash column 200 m high.
