HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE

Friday, June 9, 2017, 8:38 AM HST

KILAUEA VOLCANO
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)

Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: Kīlauea Volcano continues to erupt at its summit in
Halemaʻumaʻu and on the East Rift Zone at Puʻuʻōʻō. Yesterday's M5.3
earthquake beneath Kīlauea Volcano's south flank had no apparent effect on
these eruptions. The summit lava lake remains active and was about 22 m (72
ft) below the floor of Halemaʻumaʻu crater when measured this morning. The
episode 61g lava flow continues to enter the ocean at Kamokuna. Active
surface flows persist above and in the vicinity of the pali southeast of Puʻuʻōʻō.
These flows pose no threat to nearby communities. Low rates of ground
surface deformation and seismicity continue across the volcano.

Summit Observations: After a brief deflationary excursion yesterday, inflationary
tilt has resumed at the Kīlauea summit. The lava lake was about about 22 m
(72 ft) below the rim when measured by laser rangefinder this morning, putting
the lake surface and current spattering activity in view from Hawaii Volcanoes
National Park's Jaggar Overlook. Generally, low levels of seismicity continue,
with amplitudes of volcanic tremor fluctuating with the strength and extent of
lava lake spattering. Summit sulfur dioxide emission rates remain high.

Puʻuʻōʻō Observations: Web camera views overnight during periods of clear
weather suggest no major change at Puʻuʻōʻō. Seismicity and deformation at
Puʻuʻōʻō have not changed significantly in the last 24 hours. The sulfur dioxide
emission rate from the East Rift Zone vents has been steady over the past
several months and remains significantly lower than the summit emission rate.

Lava Flow Observations: The episode 61g flow remains active and is entering
the ocean at Kamokuna. As of May 31, the new lava delta was approximately
3.2 acres in size, extending about 100 m (328 ft) out from the sea cliff. A solid
lava ramp has formed around the stream of lava reaching the growing delta.
See the HVO web site for images. Based on web camera views overnight,
surface breakout activity continues within the 61g flow field southeast of
Puʻuʻōʻō and on the pali. The lava flows pose no threat to nearby communities
at this time.

Ocean Entry Hazards: The ocean entry is a hazardous area. Besides walking
on uneven, glassy lava flow surfaces and around unstable, vertical sea cliffs,
venturing too close to an ocean entry on land or the ocean exposes you to
flying debris from sudden explosive interaction between lava and water. Also,
the lava delta is unstable because it is built on unconsolidated lava fragments
and sand. This loose material can easily be eroded away by surf, causing the
new land to become unsupported and slide into the sea. This occurred most
recently on May 3. In several instances, such collapses have also incorporated
parts of the older sea cliff. Additionally, the interaction of lava with the ocean
creates a corrosive seawater plume laden with hydrochloric acid and fine
volcanic particles that can irritate the skin, eyes, and lungs.
This map shows recent changes to Kīlauea’s East Rift Zone lava flow field. The
area of the active flow field as of April 10 is shown in pink, while widening and
advancement of the active flow as of May 3 is shown in red. Older Puʻu ʻŌʻō
lava flows (1983–2016) are shown in gray. The yellow line is the trace of the
active lava tube (dashed where uncertain).
A steady stream of lava exiting the episode 61g lava tube pours into the
ocean at the Kamokuna ocean entry. The interaction between the lava and
ocean water causes explosive reactions, throwing bits of lava.
TIME-LAPSE sequence of lava lake activity at Halemaʻumaʻu
On May 3, Kīlauea Volcano's Kamokuna lava delta, which had been
growing since late March, collapsed. Within five minutes, between
9:55 and 10:00 a.m. HST, nearly the entire delta disappeared,
collapsing into the sea.
