Eruptions generally occur on the flanks of the volcano and produce small
cinder cones and lava flows. Cameroon was the site of one of the earliest
recorded volcanic eruptions--in the 5th century BC--observed by a Cathaginian
ship captain while sailing down the Atlantic Coast of Africa.
On 7 June, officials in Cameroon issued a stand-by evacuation warning for people living on the slopes of the Mount Cameroon Volcano. The lava flow has increased in speed to 65-80 feet per hour. The lava flow is only three miles from a village.
This information was summarized from Discovery Online.
On 29 May, earthquakes were recorded at the Mt. Cameroon Volcano. On 31 May, a 3 mile long lava flow developed, and incandescent eruptions continued at the volcano's summit. The flames and lava flow are primarily on the less populated side of the volcano. Government officials said there was no immediate cause for alarm. Mt. Cameroon is located on a seismic fault line that crosses the country of Cameroon.
This information was summarized from Smithsonian Instituion's Preliminary Notices of Volcanic Activity.
An increased volume of magma is pouring out of the Mount Cameroon Volcano. After a quiet period of six weeks, the volcano appears to be on the verge of another eruption.

MOUNT CAMEROON ERUPTION SUMMARY:
The 1999 Mt. Cameroon eruption (the sixth this century) that began on 28
March 1999 is now over. The principal vent at about 1,400 m elevation initially
sent a voluminous 'a'a flow in a south-southwest direction through dense
rainforests toward the village of Bakingili. This flow (alkalic basalt) eventually extended 6-7 km from its source vent and cut about 80 m of the important Limbe-Idenau road on 15 April. By this time, the
10-12 m thick 'a'a flow was very sluggish and ceased all forward movement
on 17 April, about 200 m from the Atlantic Coast. The last glow from the
1,400 m vent was seen on 14 April, and lava production probably ended about
this time. A new road has been built along the distal end of the flow to
restore normal traffic along the coastal road. As of late April, about 400
evacuees from Bakingili were still being housed in a nearby refugee camp,
but were expected to be allowed to return to their homes shortly.

The lava flows from Cameroon have missed the villages of Bakinguili and
Batoke and are on their way to the sea. The air and local drinking water
remains contaminated from recent eruptive activity, however. Over 1,000
people from these villages had to be evacuated due to the advancing flows.
This information was summarized from Discovery Online.
A lava flow 1.3 miles (2 km) wide and 100 feet (30 m) thick has burned
virgin rain forests and small farms on its way to the sea. The flow is
now just a few hundred yards from the villages of Bakingele and Batoke.
Authorities have issued new orders to evacuate these communities, as many
of the local residents have ignored past warnings and remained in their
homes. Soldiers and doctors have been sent to the area, and air and sea
evacuation teams are on standby. About 500 evacuees will be taken to a
camp at an abandoned airport in Tiko, 20 miles (30 km) to the east. At
least 1,000 people have already fled since the volcano began erupting two
weeks ago. Gas and ash emissions have blackened the air around the
volcano and polluted drinking water for about 2,600 people living in the
area.
This information was summarized from a report on the CNN site.
Evacuation plans are being drawn up and gas masks are being distributed to
the residents of three villages on the flanks of Mount Cameroon.
Continued eruptions have led to the advance of lava flows towards Idenau,
Batoke, and Bakingili. Lava flows may reach these villages within the
next few days. Eruptions over the weekend increased the number of
fissures feeding the flows from nine to 12. Over 100 homes have already
been damaged or destroyed by volcanic tremors during the current eruption.
This information was summarized from a report on the CNN site.
Violent quakes and lava flows forced the evacuation of many villagers in
Cameroon on March 29. Several homes have been destroyed by the lava
flows, but no casualties have yet been reported. Lava began flowing down
the southern slopes of the volcano towards the villages of Edenau and
Bakingele on March 28. Another lava flow is moving towards a
state-owned oil refinery on the outskirts of the resort town of Limbe.
Several thousand residents are believed to be living in the danger zone.
