Colima-volcano is situated about 450 km W of Mexico City. It is
not one, but two
different volcanoes, the oldest one called Nevado de Colima at 4.200m
asl, and the youngest
Volcan de Fuego or Volcan de Colima, which is 200 m lower, and is situated
5 km S of Nevado.
Approx. 300.000 people live within a 40 km radius from the volcano.
Colima is considered the most dangerous and active volcano in Mexico.
The last big eruption was in 1994, when several 'bombs'
caused big fires in the neighborhood.

Mexico's 12,540-foot Colima volcano spewed a column of rock,
ash and lava almost three miles
into the sky in its largest eruption in at least 20 years. The
government was considering evacuating
tiny communities around the volcano in the western state of Colima.
A shower of ash closed the
airport in the city of Colima 19 miles away, and lava crept down
the side of the mountain,
At 3:26 in the morning (local time) of May 30th, one registered
the greatest explosion caught by
our volcanic monitory system in the last 20 years. Satellite datas
show that the ash cloud reached a
height of 8,500m and was taken by winds to the Southeastern and
in a 5,400 lower level it was
taken to the Northeast. 1:48 hours after the explosion the Southeastern
portion extended 102 km
from the volcano and the Northeast portion extended 81,5 km. The
pyroclastic flows headed in
a direction westward.

a video at www.ucol.mx - 5 minutes of the eruption
19:10 local time yesterday the largest explosion since 1999 was
registered, with a height of the
column that exceeded 3.000 m above the summit. Pyroclastic
flows weresendt down the San
Antonio and Monte Grande ravines, at distances considered preliminarily
between 4 and 5 km.
Friday, March 11th, 2005
In last the 24 hours yesterday, 2 explosions have been registered.
At 08:10 a.m. a greater explosion
was registered, and that was the largest there has been this year.
The event produced piroclásticos
flows by South, the West and North flanks of the volcano, and
they reached about 3 kilometers.
The ash cloud I travel quickly to the Northeast and its considered
height was around 2000 ms
above the crater. Ash fall has been reported in City Guzmán,
Jalisco and populations nearby.
It is possible to mention that the amount of ash emitted until
the moment does not put risk to the
health of the population. One does not discard that the activity
evolves towards an explosive scene
like the 1999 type or greate,r that can cause a landslide.

As of the 4th of November, the Universidad de Colima reported
that during 27 October to
1 November, block-lava flows continued to travel down Colima's
N, W, NW, and S flanks as they
have since 30 September. Several explosions occurred daily. By
1 November, the block-lava flows
on the N flank reached about 1,800 m long and about 200 m wide,
and on the WNW flank
block-lava reached about 600 m long and 200 m wide at its widest
point. During the report period,
block-and-ash flows spilling from the fronts of the advancing
block-lava flows on the W flank
reached ~2 km from the summit.

last the 24 hours have been registered approximately 112 landslides
on the North flanks,
the Northwest, the West and the south because the lava emission
in blocks continues.
Following report was issued at noon, yesterday, local time.
The lavafront on the North flank is at least 1200 m of length
and 150 ms wide approximately.
The lavafront on the NW flank is at least of 400 ms length and
200 m wide.
The landslides, which all come from the western lavafront, stay
in the rank of up to 2 km from the top.
During the last 24 hours there have been registered 23 small explosions.
The ash presence in the atmosphere is due to the fragmentation
of the lava blocks that descend
on the flanks.

Thursday, October 7th, 2004
During 24 hours on Tuesday and Wednesday 294 landslides came down
by all flanks, because the
lava emission partly in blocks, continues. The flow on the South
side has increased.
The lava front on the North flank, reaches approximately 600m
of length and is 150 ms wide.
The lava front on the WNW flank has reached 250 ms approximately.
During the same periode 32 small explosions with peak altitudes
of 400 m.s have been registered,
and great activity of degasificación is reported.
The landslides have come as far as up to 2 km from the top.

||As of the 4th of October, the Universidad de Colima
reported that Colima volcano erupted on
Friday, October 1st. A wide stream of lava had been clearly visible
at night flowing down the volcano.
A column of ash was ejected several miles into the air. Explosions
have continued since activity
started with small blasts on Wednesday. The activity has been caused
by pressure building under a
dome that covers Colima's crater. Smoke and gas are now emitting
from a crack in the dome.
It is hoped the lava flows continue, relieving pressure inside the

A comparison of the total values of the amplitude of the daily seismic
registries (RSEM) for the
last 24 hours, with the eruptions of 2002 and 1998, suggests the
extrusion of this eruption is
approximately five times greater than the previous ones.
It is to be hoped that the lava emission continues as until now.
Yesterday at 20:00 hours and
00:20 today, October 1st, the web-camera showed material expelled
from the top towards the
northern side of the volcano. These landslides continued during
the night extending towards the
western side and throughout the day they have been increased in

night there were three explosion, where incandescent material
were shot out from
the volcano. So far there has been no damages to human or on any
material in the communities
A zone of exclusion goes 6,5 kilometers round the volcano, as
well as a preventive zone
11,5 kilometer radius is recommended. Rural communities consists
of only 1.000 inhabitants
closer than 10 kilometers from the summit, and in case of intensified
activity those will
hopefully be evacuated.
The explosions began Wednesday after the collapse of a dome that
had formed recently in the
crater of the 12-thousand-533-foot volcano.
Small landslides began on the north side of the volcano Wednesday
night and spread to the
west side on Thursday. The slides also grew in size, according
to the volcano observatory
at the University of Colima.
For now, officials say there's no need to evacuate the surrounding
communities. They remain
on yellow alert, which bars people from within four miles of the

|The Universidad de Colima reported that as of
10 February about five explosions occurred at Colima daily, which
was slightly more than during the previous few months. Ash columns
rose 2-3 km above the crater and predominately drifted NE and ENE.
A significant explosion on 9 February at 0958 produced a plume to
~3.6 km above the volcano that drifted NE. According to the Washington
VAAC, during 12-17 February ash plumes were sometimes visible on
satellite imagery at a maximum height of ~3 km above the crater.
|VAAC reported that on 6 September at 1026 a strong ash emission
occurred at Colima. The resultant ash cloud rose to ~6.7 km a.s.l.
and drifted N. Ash was not visible on satellite imagery. Another
ash emission occurred on 8 September that was visible on the Colima
from the web-cam early in the morning (6.30 - 6.41 GMT)
seconds between. 7.22-7.23 GMT

the past 500 years the Colima volcano has had a frequency in eruptions
at about 30 years.
Look at these years: 1585, 1606, 1622, 1690, 1818, 1869, 1890, 1903
