The Guagua Pichincha volcano is situated about10 km from Quito, capital
raises 4.794m, from where you have a splendid view of the city.
November 5th, 2002
The Instituto Geofisico (IG), reports that 6 earthquakes of long
period, 3 volcano-tectonic and
3 explosions, happened at 2056 (local time), 2115 and 2154, of yesterday.
The most important explosion was at 2154 with a reduced displacement
of 12.9 cm2. The report of the Guard of Refuge indicates that it left
a new fumarole in south edge the crater that contains the new dome,
and it gave much noise and the scent of sulfur is strong. Around small
craters new material is observed. The volcano stays with a moderate
phreatic activityThe increase in the number of earthquakes, is the result
of this phreatic process.

alert was raised again to ORANGE for Lloa and its vicinity (map
here) Huruarco, with 100 inhabitants, Palmira with 16, San Jorge
18, were all evacuated during last night. LLoa, which has a population
of 1500 people will
be evacuated to day. Cattle and other animals will also be moved during
was made when seismicity declined. This indicates a possible eruption
during the coming 3 to 5 days, similar, or greater to the one of October
of seismicity yesterday was lover than previous days, when number of
quakes were around 3500 per day. On the other hand, temperature on the
flanks of the crater was higher, thus indicating that somethins is going
on inside, which is not allowed to come out.
Meanwhile, the inhabitants of
Quito can visit the Tungurahua volcano, near
Ambato, 125 km further south, to look at the spectacular show from this
volcano - or will it be
Guagua Pichincha to explode first?
October 21st, 1999
We are sorry that we are not able to keep this page updated, but will
try to give short information as often as possible. Guagua is now showing
up with another new dome, and tremor activity is increasing again. Another
eruption similar to the one of October 5th is anticipated. Also someone
has began talking about both Tungurahua and Guagua Pichincha
is going to erupt at the same time....To day Tungurahua,
less than 100 miles further south,
has never been closer to red alert. News about the volcanic activity
from both volcanoes is available from SWVRC
daily from around 15.00 GMT.

New ash and vapor explosion yesterday, and new ash-rain in the city.

October 6th, 1999
During the last 24 hours 334 LP quakes were registered, 420 hybrid and
88 quakes forced by rockfalls. Those values were similar to the day
before. Most quakes were in the western part of the boiler, in depth
of 1 to 2 kilometers. In addition there were 17 transmissions of ash
and vapor, including LF tremors. The most important eruption happened
at 21.27 local time, and had 'a reduced displacement of 36 cm2',
which is described as large (and which I don't
still understand the meaning of...??? anyone around knowing better?).
This eruption sent an ashcloud 8.000 meter up in the air,
from were it moved southwesternly.
Ash falling down was reported from Chillogallo area
in Quito, where also a strong smell of sulphur was felt. Yellow alert,
which has been issued day before yesterday is maintained.
Activity has been lower last day, but at the same time more volcan tectonic
quakes have occured, and magma is increasing. Still one hopes that the
now broken dome will let gasses and some magma pass, to release energy
thus avoiding an explosion.
1 Inch of ash felt over Quito yesterday, and strong smell of sulphur
awakened many people during the night of yesterday. Alltogether more
than 400.000 school pupils are staying home, as schools are closed.
Hopefully now, the dome will partly broke up, as it
now allready has, and lava will come out and cool off, then form another
dome, and every time this happens, gasses will emit, and the pressure
be lowered. Thus an explosive eruption will probably be avoided.
An earthquake of 3.4 magnitude also occured yesterday
with center in the northern part of Quito. Number of quakes at the volcano
has decreased a little again.
At .20.30 GMT yesterday, the evacuation of Lloa started. Lloa is a small
population of about 5000 inhabitants. About 2.500 farmers denied evacuation.
Sivil Defence, Red Cross, police etc forced them to evacuate, and to
get away from the danger-zone immideately, letting their property behind.
Another 60 smaller communities will have to be evacuated while the alert
is still ORANGE, waiting for RED ALERT.

At 20:30 local time yesterday night Orange Alert
Seismic activity increased from 2 quakes per minute to 3 quakes during
yesterday. It is expected that one of the two types of eruption showed
below will be what to come.
vulcanian eruption- - and plinian
Public schools and the University are
closed. People are urged to buy a food-reserve to last for 5 days. Routes
for evacuation are being published.
"Few, if any, volcanoes would have kept from erupting, if they behaved
in the same way as Guagua Pichincha has the past days" says Director
of the Institute Geofysico.
Magma is extending, and quakes are located to about
3-4 kilometers down, where one expects the magma to fill up. Gas is
erupting faster now, and consists of even more helium, which is an indication
that magma is coming up from below.

The morning of Sunday began with a large eruption, followed by a sound
like a jetplane taking off. A lahar developed, and followed the Cristal
river. Ashfall in nearby villages covered vegetagion and cars in the
streets. Last 24 hours showed 1300 volcanic quakes. Smell of sulphur
Institute Geofisico says last 24 hours has shown
an dramatic increase in activity.
An eruption cloud from fumaroles has risen to 1500 m above crater.
Yesterday Guagua Pichincha sent an ash and gas-cloud as high up as 6.000
meters, easily seen from Quito.
Pressure inside the volcano is increasing, indicating magma is trying
to find its way out. From the volcano goes a tectonic crust, passing
through Quito, and 40 km southward.
Riskzone is the slopes of the volcano, with 7.400 hectar
wood, farmland and 90 districts
having a population about 100.000.
