Location: 5.6S, 150.5E
Elevation: 742 m
Last Update: April 27, 2004
This information was summarized from the GVP/USGS Weekly Volcanic Activity Report
Volcanic and seismic activity remained at low levels: Small amounts of "fume"
were released with trace amounts of SO2. A local tectonic earthquake on 9 August
led to an increase in energy release and number of earthquakes recorded at one
seismic station.

Lava continued to flow, but at slower rates than before. Along the fissure
system, and from the summit crater, vapor continued to be emitted. Seismicity
remained at low levels and a decrease in the number earthquakes was reported.

Seismicity continued at low levels; no significant ground deformation was recorded.
Also, lava flows continued and white vapor was released from vents in the fissure
system. Incandescence was visible on the evening of the 28th.

Weekly Volcanic Activity Report
Through Dec. 2nd, effusive lava accompanied with vapor continued to erupt.
Also small volcanotectonic earthquakes, stayed at background levels.

Volcanic activity continued but residents in low-risk areas were allowed to
return to their residences.

On Nov. 3, a low-level ash plume was visible on satellite imagery.

Volcanic activity has continued and scientists found that inflation has continued
with ~1 cm of uplift occurring in the past month. Fifteen thousand residents
have been evacuated since activity began in August.

Large volumes of lava continue to flow from a vent in the NE portion of a fissure
system inside the caldera.

On September 7 and 8, a 1.5-km high ash-and-steam plume drifting northwest was
observed on satellite images.

Lava erupted from four of the five craters northwest of the Pago central cone during August 25th to September 3rd. The largest amount of lava was emitted from the lowest cone, the lava flowed northeast and then was directed southeast after reaching the crater wall. No eruption from the cone was observed, only blue-white fumarolic gas was emitted.

Intermittent eruptions with low ash content produced low-level plumes on the
16th. The low level of activity was expected to continue according to the Rabual
Volcano Observatory.

The eruption that began last week is still continuing through this week. The
eruption was characterized by the ejection of light gray to dark ash clouds,
with very little ash being deposited in areas around the volcano.

An eruption that began on August 5th at approximately 05:30 (local time) caused
an 18-kilometers wide ash cloud that rose to 1.2 kilometers above sea level
and extending 37 kilometers northwest. Another eruption occurred around midday,
raining ash on Hoskins. The Rabaul Volcano Observatory reported that eruptions
were continuing on August 6 at 1800 (local time) with the ash plume moving north-northwest
to north.
