Small eruptions are recorded since 1828, but only in 1834 the volcano showed a significant activity with an eruption of ash accompanied by strong underground eruptions. Other explosions were recorded in 1880, 1895, 1899, 1903-1906.

One of the most important historical eruptions, with explosion of stones, mud and ashes was recorded on January 25 1910. A column that reached the 8,000 meters was formed. The volume of ejected ash reached 800,000 cubic meters. Other major explosive eruptions occurred in 1914, 1915, 1916, 1925, and 1929, 1932-34.

In 1968, there were  eruptions and fumarolic activity which continued in 1970, 1979, 1987 and 1989. In 1989 and 1990 as a result of the activity, the main lagoon crater began to decrease.

In 1994, there were some eruptions of ash, until the lagoon dried, it was not recovered until 1998, and then it was visible again.
