Scientists measure a shattered block ejected during Colima's February 10, 1999 explosion. Several impact craters were measured about 3 km NE of the summit, including this block, which landed on the road to the caldera. This was the biggest explosion reported for the volcano in the last 80 years. A substantial number of incandescent blocks fell and started fires on the volcano's upper slopes.
