How many people died in colimas last eruption?

Surprisingly, nobody. The most violent eruptions ocurred in 1585, 1606, 1622, 1690, 1818, 1890, 1903, 1913, 1999 and 2005.

As the Colima volcano is a stratovolcano, its lava flows are very slow; the biggest danger takes the form of pyroclastic flows (dense clouds of superheated gases, ash and debris), but these rarely reach beyond 7 kilometers (4.3 miles) from the volcano's cone. Most communities around the volcano are at a fairly safe distance of 16 kilometers (10 miles) or more from the cone.
