Kilauea Daily Update issued Jun 19, 2007
14:32 HST Volcanic-Alert Level WATCH - Aviation Color Code ORANGE

Report prepared by the Hawaiian Volcano Observatory
(HVO):

Field crews have returned from this morning's overflight to report
more details on the Episode 56 outbreak. The fissure that erupted lava was about
200 m (600 feet) long. The erupted lava extended only about 50 m (150 feet) from
the fissure. When the crew arrived at 6:45 a.m. this morning, the flows were
still moving sluggishly and the fissure was emitting heavy smoke and steam. By
the time they left at 11:00, the flow had stopped and the smoke and steam had
decreased significantly. We continue to record intermittent seismic tremor and
earthquakes in the area.

At Kilauea summit, two days of deflation have
turned into inflation. Seismic tremor levels, indicative of subsurface magma
movement, continue to decrease. GPS receivers in the vicinity of Makaopuhi
crater and Kane Nui o Hamo are recording continuing extension (widening), which
has slowed significantly since yesterday. At this location, the rift zone is now
nearly 100 cm (33 inches) wider.

Pu`u `O`o vent continues to collapse.
Views into the crater this morning were difficult due to extensive steaming.
From a few glimpses, HVO observers could see that the crater floor continues to
collapse from yesterday and that several chunks of the cone itself collapsed on
the west side.

HVO has scheduled another overflight tomorrow morning. We
continue to monitor the situation closely.

(HVO):

New Lava outbreak in Upper East Rift Zone of Kīlauea
Volcano

The intrusion of magma that was signaled by a swarm of
earthquakes and rift zone widening over the last two days has finally made it to
the surface. Early this morning, HVO scientists confirmed that a small outbreak
of lava had oozed from a 250 m long fissure in the forest northeast of Kane Nui
o Hamo, approximately 6 km west of Pu‘u ‘Ō‘ō and 13 km southeast of Kīlauea
summit. In addition, steam was issuing profusely from a spot high on the north
flank of Kane Nui o Hamo. This event will be called Episode 56 of the ongoing
eruption.

When observed at about 7 a.m., the lava was cooling and not
advancing. Steam and gas were issuing from the fissure. The outbreak appeared to
be a short one that had been over for at least a few hours by the time it was
seen this morning. This may be related to the abrupt eastward migration of
earthquake epicenters into this area noted between 3:45 and 5 p.m. yesterday.
Small earthquakes continue to occur in the area at low levels.

The crater
of Pu‘u ‘Ō‘ō vent was shrouded in steam this morning and no views were visible.
No incandescence was seen in the webcam overnight. No active surface flows were
seen anywhere on the flow field. The only molten lava seen was a small stream
dribbling into the ocean at Poupou that that may be draining from the Campout
tube system. Gas emission measurements yesterday confirmed that the activity
level at Pu‘u ‘Ō‘ō has decreased significantly.

Kīlauea summit continues
to deflate, although at decreasing rates. Seismic tremor levels, indicative of
subsurface magma movement, also decreased overnight. GPS receivers in the
vicinity of Makaopuhi crater and Kane Nui o Hamo continue to record extension
across the rift zone; preliminary data indicate total widening of nearly 95 cm
(37 inches).

Report prepared by the Hawaiian Volcano Observatory
(HVO):

The earthquake swarm in the upper East Rift Zone of Kīlauea
Volcano that started early Sunday morning, June 17, is continuing. Tremor at the
summit area remains strong. The earthquake activity between Makaopuhi and Napau
craters, farther east than where the earthquakes began, has slowed significantly
in the past 12 hours.

Tiltmeters in the summit area continue to show
deflation, but at slowly declining rates. A tiltmeter on Pu`u `O`o is recording
steady deflation. GPS receivers in the vicinity of Makaopuhi crater continue to
record extension across the rift zone; preliminary data indicate total widening
of nearly 90 cm (35 inches).

All data indicate that an intrusion of magma
started at shallow levels in the Mauna Ulu area early on June 17. The intrusion
has moved eastward about 6 km (3.8 miles) along the rift zone during the ongoing
activity.

No incandescence is visible on the Crater cam views of the Pu`u
`O`o crater. A large area of the crater floor has subsided by about 20 meters
since the earthquake activity began early Sunday morning, and no active surface
lava flows were visible between Pu`u `O`o and the ocean on Monday. This strongly
suggests that activity at Pu`u `O`o has decreased substantially in response to
the intrusion.

An overflight of Pu`u `O`o and the surrounding area is
scheduled for early Tuesday morning. HVO staff continues to monitor the volcano
closely.

Earthquake Swarm Beneath Kīlauea’s Upper East Rift Zone
Continues

The earthquake swarm in the upper East Rift Zone of Kīlauea
that started early Sunday morning, June 17, is continuing. From midnight to 3:45
p.m. on June 18, HVO located about 3 earthquakes greater than magnitude-1.7 per
hour, down from the average of 12/hr yesterday, June 17. At 3:45 p.m. today, HVO
detected an increase in earthquake activity between Makaopuhi and Napau craters,
farther east than previously noted. The activity lasted about an hour and rates
were approaching yesterday's levels. Currently, the number of events average 3
per hour.

Tiltmeters in the summit area continue to show deflation; the
rates have increased slightly since 3:45 p.m. A tiltmeter on Pu`u `O`o also
registers steady deflation. GPS receivers in the vicinity of Makaopuhi crater
continue to record extension.

Crater cam views of Pu`u `O`o crater are
dark.

An overflight is scheduled for Tuesday morning to evaluate
changes. HVO staff continues to monitor the volcano closely.

Earthquake Swarm Beneath Kīlauea’s Upper East Rift Zone
Continues

The earthquake swarm in the upper East Rift Zone of Kīlauea
that started early Sunday morning, June 17, is continuing. From midnight to 3:45
p.m. on June 18, HVO located about 3 earthquakes greater than magnitude-1.7 per
hour, down from the average of 12/hr yesterday, June 17. At 3:45 p.m. today, HVO
detected an increase in earthquake activity between Makaopuhi and Napau craters,
farther east than previous quakes, that lasted about an hour. During this
increase, the earthquakes were occurring at near yesterday's rate. As of this
posting, the rate of earthquake occurrence has again decreased.

Tiltmeters in the summit area continue to record steady deflation,
totaling more than 40 microradians since early Sunday; the rates have increased
slightly since 3:45 p.m.. GPS receivers in the area of most intense seismic
activity continue to record widening across the rift zone near Makaopuhi crater;
preliminary data indicate total widening of more than 70 cm (28 inches). An HVO
field crew have identified new cracking in the area between Mauna Ulu and
Makaopuhi consist with this widening. A tiltmeter on Pu`u `O`o continues to show
steady deflation.

This morning, HVO scientists inspected Pu`u `O`o vent
and the entire flow field. The crater floor within the vent had dropped about 20
m. Several spatter cones within the crater had further collapsed into pits. Lava
ponds were seen in East Pond vent and the pits that were January vent. No active
surface lava was found on the flow field; no flowing lava was seen in skylights
in the Petunia tube indicating that it is no longer active. Similar views were
not available on the Campout tube, but lava was seen trickling into the ocean at
the Poupou entry. This information strongly suggests that activity at Pu`u `O`o
has decreased substantially in response to the June 17 intrusion.

Such an
effect on the activity at Pu`u `O`o has been expected because similar past
events, most recently the 1997 episode 54 eruption and the 1999 intrusion,
resulted in cessation of Pu`u `O`o activity for several days to
weeks.

All data indicate that an intrusion of magma started in the Mauna
Ulu area early Sunday morning and moved slowly 5 km (3 miles) east along the
rift zone throughout June 17. This afternoon, the intrusion moved a bit farther
east in a burst of earthquake activity starting at about 3:45
p.m.

Another overflight is scheduled for Tuesday morning to evaluate
changes, if any. HVO staff continue to watch the volcano closely.

Earthquake Swarm Beneath Kīlauea’s Upper East Rift Zone
Continues

The earthquake swarm in the upper East Rift Zone of Kīlauea
that started early Sunday morning is continuing but at a lower rate. Most of the
earthquakes are located between Pauahi and Makaopuhi craters at depths of about
1.5-3 km. Less than 10 small earthquakes per hour are being recorded in this
area compared to more than about 100 per hour Sunday morning. Seismicity in the
summit area consists of strong tremor.

Tiltmeters in the summit area are
recording steady deflation, totaling about 40 microradians since early Sunday;
tilt rates are slowing this morning. GPS receivers in the area of most intense
seismic activity have recorded widening across the rift zone in near Makaopuhi
crater that has slowed; preliminary data indicate total widening of more than 40
cm (15 inches). A tiltmeter on Pu`u `O`o is also showing steady
deflation.

Incandescence has not been visible from the East Pond vent in
the crater of Pu`u `O`o since the early morning hours; steam from the crater
obscured views for most of the night and morning. On Sunday afternoon, HVO
observers noted many rockfalls from the south wall of Pu`u `O`o cone and
collapse of the crater floor around the vents. January vent collapsed at 4:30
p.m. This morning after the sun rose, Pu`u `O`o crater is steaming; the floor is
still there but the January vent and Drainhole pits have enlarged. An HVO crew
of observers is scheduled to inspect Pu`u `O`o and the flow field this
morning.

All data indicate that an intrusion of magma started in the
Mauna Ulu area early Sunday morning and moved slowly 5 km (3 miles) east along
the rift zone during the day. The intrusion appears to be
waning.

Fieldwork in the Mauna Ulu - Makaopuhi area is scheduled for
Monday morning to evaluate changes, if any.

Early Morning Earthquake Swarm Beneath Kīlauea’s Upper East
Rift Zone

About 70 shallow earthquakes in 2 hours occurred beneath the
upper east rift zone of Kīlauea early this morning. The swarm began at 2:15 a.m.
on Sunday, June 17 and is ongoing. The earthquakes are centered 1 km (1 mile)
southwest of Mauna Ulu and are concentrated between 1.5 and 3 kilometers (1-2
miles) deep. As of 4:30 a.m., ten of the quakes had magnitudes greater than 3
and were felt by nearby residents. All data so far is consistent with the event
being a shallow intrusion of magma. The Hawaiian Volcano Observatory is watching
the situation closely and has deployed field crews to the scene.

Hawai‘i
Volcanoes National Park has taken the following precautionary measures: Chain of
Craters road is closed. Crater Rim Drive is closed between Jaggar museum and the
Thurston lava tube parking lot. NPS personnel are sweeping both roads to
evacuate visitors.

Kilauea Information Release issued Jun 17, 2007 08:06 HST
Volcanic-Alert Level WATCH - Aviation Color Code ORANGE

Report prepared by the Hawaiian Volcano
Observatory:

Summary: A swarm of earthquakes and rapid deflation started
at 2:15 a.m. in the upper east rift zone near Mauna Ulu. The event is most
likely an intrusion of magma. Low magnitude earthquakes are continuing at a rate
of one per minute. The summit tiltmeter network recorded strong changes nearest
the focus of earthquakes with smaller responses in the summit caldera and even
smaller at Pu`u `O`o vent.

The summit continues to expand at slow rates.
Kilauea volcano continues to erupt from the Pu`u `O`o vent on the East Rift
Zone. Lava feeds Pu`u `O`o crater vents, vents in collapse areas on the south
side of Pu`u `O`o cone, and the PKK tube, which feeds two lava tube systems,
named the Petunia and Campout tubes. The Petunia flow continues to advance and
came over the top of Pulama pali about June 14. The Campout tube is feeding
widespread surface flows on the west side of the flow field and the Poupou ocean
entry.

The last 24 hours at Kilauea summit: An earthquake swarm started
at 2:15 a.m. with at least 70 quakes recorded in the first two hours. At least
10 of those quakes were magnitude-3.0 or greater. As of this writing,
earthquakes of approximately magnitude-1.0 are occurring at a rate of one per
minute. The earthquake activity is centered between Mauna Ulu and Pauahi crater.
The tiltmeter network recorded significant deflation, consistent with extension
across the upper east rift zone and summit. Seismic tremor remains at low
levels.

Air quality was good.

Last 24 hours at Pu`u `O`o: No big
changes; fog and rain obscured views into the crater. Incandescence could be
seen reflected in the gas plumes at East Pond, January, South Wall Complex, and
Drainhole vents. The POC tiltmeter recorded weak deflation in response to the
summit activity. Seismic tremor remains at moderate levels. HVO scientists are
en route to Pu`u `O`o to directly assess any activity changes at the vent or on
the flow field.

NPS eruption crew report from the coast for Saturday
evening: The front of the Petunia was visible advancing down Pulama pali. The
`a`a flow had advanced to the 1100'. Breakouts could also be seen during the day
on the Campout flow on the pali. Surface flows on the east side were widespread
inland of Poupou. The steam plume from the Poupou entry was visible by day.

The last 24 hours at Kilauea
summit: Several small, shallow earthquakes were recorded beneath the summit
immediately south of Halema`uma`u crater, away from the summit beneath the
southwest rift zone, and beneath the south flank. The tiltmeter network recorded
no significant inflation or deflation across the summit; in the past two days,
the UWE tiltmeter, across the road from HVO, recorded two abrupt but small
deflations that are not accompanied by significant changes in seismicity. These
have happened before and usually occur in runs - we are watching them but don't
interpret them as a significant change in activity. Seismic tremor remains at
low levels.

Air quality was good.

Last 24 hours at Pu`u `O`o: No
big changes; fog and rain obscured views into the crater. Incandescence could be
seen reflected in the gas plumes at East Pond, January, South Wall Complex, and
Drainhole vents. The POC tiltmeter recorded the usual oscillations; the
inflation recorded yesterday has slowed accompanied by a decreasnoone in
rainfall. Seismic tremor remains at moderate levels.

NPS eruption crew
report from the west sides of the coastal plain for Friday evening: The front of
the Petunia was visible advancing down Pulama pali. It appeared to be 100-200
yards wide and had advanced to the 1200' level by 9 pm. Breakouts could also be
seen from the Campout flow on the pali below the bottom of the big kipuka.
Surface flows on the east side were widespread inland of Poupou. The steam plume
from the Poupou entry was visible by day and was replaced by dim glow at night.

east rift zones that started May 12, 2007 may be waning.

The long story
that won't change daily: Over the past several months, Kilauea caldera has been
expanding at a rate of 1.5 cm/month indicating minimal magma storage there; most
of the magma supply continues to feed the Pu`u `O`o vent. Pu`u `O`o cone is
slowly collapsing as shown by cracks spreading on its south flank and about 1
cm/month subsidence of its north flank.

The PKK lava tube, the primary
tube from Pu`u `O`o, is active but only to feed the Campout and the Petunia
tubes within about 1 km from the vent. The Campout tube provides lava to the
coast toward the base of Royal Gardens subdivision and into the ocean on May 16
at Poupou. The Petunia flow has advanced about 2 km and is not yet visible below
the pali. While we can't see it except on helicopter overflights, twice daily
satellite imagery confirms that the Petunia flow is still somewhat active. Lava
continues to enter the ocean only at the Poupou location within the Hawai`i
Volcanoes National Park.

The last 24 hours at Kilauea summit: A few,
small, shallow earthquakes were recorded in the summit; most were deeper
earthquakes recorded in the south flank. The tiltmeter network recorded no to
slow inflation across the summit. Seismic tremor remains at low levels.

Air quality was good.

Last 24 hours at Pu`u `O`o: No big changes;
fog and volcanic gas obscured views into the crater. Incandescence could be seen
reflected in the gas plumes at East Pond, January, South Wall Complex, and
Drainhole vents. The POC tiltmeter recorded the usual oscillations on slow
inflation. Seismic tremor remains at moderate levels.

NPS eruption crew
report from the coast for Tuesday evening: No incandescence visible from the
west side above or on the pali or on the coastal plain. A steam plume could be
seen from the Poupou entry by day; incandescence was visible at night.

Report prepared by the Hawaiian Volcano
Observatory:

Summary: Kilauea volcano continues to erupt from the Pu`u
`O`o vent on the East Rift Zone. The eruption is stable - the Poupou ocean entry
continues to build a delta. The flurry of small shallow earthquakes in the upper
east rift zones that started May 12, 2007 may be waning.

The long story
that won't change daily: Over the past several months, Kilauea caldera has been
expanding at a rate of 1.5 cm/month indicating minimal magma storage there; most
of the magma supply continues to feed the Pu`u `O`o vent. Pu`u `O`o cone is
slowly collapsing as shown by cracks spreading on its south flank and about 1
cm/month subsidence of its north flank.

The PKK lava tube, the primary
tube from Pu`u `O`o, is active but only to feed the Campout and the Petunia
tubes within about 1 km from the vent. The Campout tube provides lava to the
coast toward the base of Royal Gardens subdivision and into the ocean on May 16
at Poupou. The Petunia flow has advanced about 2 km and is not yet visible below
the pali. While we can't see it except on helicopter overflights, twice daily
satellite imagery confirms that the Petunia flow is still somewhat active. Lava
continues to enter the ocean only at the Poupou location within the Hawai`i
Volcanoes National Park.

The last 24 hours at Kilauea summit: Small
shallow earthquakes were recorded in the summit; deeper earthquakes were
recorded in the south flank. The tiltmeter network recorded no to slow inflation
across the summit. Seismic tremor remains at low levels.

Air quality was
good but a computer problem prevented data from being recorded for much of the
last 24 hours.

Last 24 hours at Pu`u `O`o: No big changes; fog and
volcanic gas obscured views into the crater. Incandescence could be seen
reflected in the gas plumes at East Pond, January, South Wall Complex, and
Drainhole vents. The POC tiltmeter recorded the usual oscillations on very slow
deflation. Seismic tremor remains at moderate levels.

NPS eruption crew
report from the coast for Monday afternoon: "Great" surface flow activity is
reported at the base of the pali and Royal Gardens subdivision on the eastern
side of the flow field. A steam plume could be seen from the Poupou entry by
day.
