OVSICORI-UNA report that no ash emissions was detected from the volcano. Seismicity is of a stable amount. Carbon dioxide/Sulfur dioxide (CO 2 / SO 2) and Hydrogen sulfide/Sulfur dioxide (H 2 S / SO 2) ratios remain within a normal range. Sulfur dioxide emissions was measured at an average of 100 tonnes/day. Crater depth was measured at 140 m, compared to 220 m in 2019. This shallowing of the crater is due to “frequent collapses of the internal walls.”

Colima volcano photos
: This beautiful stratovolcano in western Mexico is one of the most active volcanoes on the American continents. It is known for its often spectacular explosions and sometimes glowing avalanches.
Igneous or magmatic rocks
: The most primitive rock type forms when magma (molten rock) solidifies - either inside the earth (plutonic rocks) or during volcanic eruptions (volcanic rocks). A short overview.
A selection of photos of different features: lava flows, lava fountains, lava lakes, fumaroles and more.
