Colima is located 280 miles (450 km) west of Mexico City. Nearly 300,000 people live within 25 miles (40 km) of the volcano. It is considered Mexico's most dangerous and active volcano. In 1991, Colima produced a dome that rose 100 ft (30 m) above the crater rim. The dome collapsed producing flows on the upper slopes of the volcano. Bombs were also shot from the volcano during this event, causing several brush fires.

May 11, 1999
A strong explosion occurred at the summit dome of the Colima Volcano. The shockwave could be felt in the city of Colima. An eruptive column rose up to more than 7,000 m.a.s.l. The Civil Protection authorities reported that the explosion triggered two small pyroclastic flows that descended on Barranca La Lumbre. The ballistic projectiles reached distances up to 4.5 km, causing small fires on the Southern, Western, Northern, and Southwestern parts of the edifice.
This information was summarized from the Smithsonian Institution's Preliminary Notices of Volcanic Activity .
February 22, 1999
Activity at Colima has increased over the last 24 hours. Four explosive eruptions have occurred at the summit. There has also been an increase in seismic activity. The new danger zone has a radius of 6.5 miles (10 km) from the summit.
This information was summarized from the Smithsonian Institution's Preliminary Notices of Volcanic Activity
February 14, 1999
Further explosions and small earthquakes forced the evacuation of about 350 more individuals from the flanks of Colima on February 14. Small pyroclastic flows have accompanied many of these explosions. Army troops remain in the area to guard villages against looting.

February 11, 1999
Toxic gasses released during an eruption of Colima forced the evacuation of 118 people from the town of San Marcos. Vulcanologists detected sulfur dioxide in the volcano's emissions. An eruption plume from the event reached heights of 3 miles (5 km). There were no injuries or property damage caused by the eruption, but grass fires were started from a small lava flow.

January 5, 1999
The eruption that began in November is waning. The lava flows have not lengthened significantly since late December. The main flow is 9000-10,000 ft (2700-3000 m) long and 1500 ft (500 m) wide. The active second flow is about 7000 ft (2200 m) long. Small block and ash flows occur from the margins of this flow. Both flows are flowing down the Cordoban Ravine. Areas that were evacuated due to recent acivity are permitting indivicuals to return.
This information was sent to us by Dan Shackleford and summarized from the University of Colima website.
November 19, 1998
Nearly 250 people have been evacuated from villages surrounding Colima due to warnings that an eruption is likely to occur within days. Thousands of small tremors have been recorded at the volcano. A plume was seen above the volcano on November 18. Planes surveying the volcano recorded temperatures of 1,470 degrees Fahrenheit (800 degrees Celsius) inside the crater. Lava was also reported to have risen high within the crater and is in danger of spilling over the crater rim.
