Explosions occurred very often, normally 30 or 40 explosion everyday. A major indirect impact of activity has been the frequent mobilization of loose volcanic material during the rainy season, which has resulted in numerous lahars (mudflows). These lahars have damaged infrastructure and settlements, notably El Palmar Viejo village 10km downstream of the volcano, which had to be abandoned in 1998.
One of the most bigest explotion ocurred on 25th april 2010, volcanic material was lunched over 27230 ft/8300 mts. And the most mortal explotion was on 1929, killing more that 2,500 persons. At least 10 persons died in the last years, some intoxicated, other after falldowns or hitted by rocks.
Getting ThereThe summit of Santa Maria volcano provides a birds-eye view of activity at Santiaguito. Alternatively, viewpoints exist to the North. Approach from the South is complicated by private fincas and numerous inpassable deep erosion gulleys. Climbing on El Brujo Dome is possible via a Northerly approach, but a guide is absolutely necessary to find the route. Clearly, this is dangerous and rarely offers better views than the other locations mentioned. Recently, even climbing onto the rim of active Caliente dome has been offered.
This geographical location would be very useful using a GPS, also recommended to go with an experienced guide.
Canaleta Arriba (big rocks)-14º45´10-91º34´26-2297
El Caliente-14º44´39-91º34´13 (Never try to go this point, this final location is a GoogleEarth navigator)
CampingIs possible to camping in a crater area "Circus". But no facilities at all. No huts, no water, be prepare with enough water and food.
