Lava Events (continued)
July 8-22, 2010
HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
Saturday, July 24, 2010 7:35 AM HST (Saturday, July 24, 2010 17:35 UTC)
Lava from the TEB vent flowed through tubes that carried lava down-slope to feed active surface flows in two locations on
the coastal plain: a cluster of advancing lobes about 1 km (0.6 mi) behind and to the west of the lead lobe that has been
creeping east over highway 137 in Kalapana and expanding to the south against the north-facing scarp of Hakuma horst
(see status report from yesterday afternoon). Surface activity continued through dawn as suggested by thermal anomalies
recorded in GOES-WEST imagery overnight. Another update on Kalapana activity will be posted by 4 pm H.s.t.

Saturday, July 24, 2010 4:24 PM HST (Sunday, July 25, 2010 02:24 UTC)
Lava from the TEB vent is flowing through tubes that carry lava down-slope to feed active surface flows in two locations on
the coastal plain:
(1) Lava moving along Hwy 137 has not advanced significantly eastward; instead, substantial activity has expanded the
flow to the north and south filling the area between the highway and the northern edge of Hakuma horst (see map). As of
1:30 pm this afternoon, active lava had destroyed an out building and entered the driveway of the western-most house on
HWY 137.
The lava is also expanding to the west along the northern edge of Hakuma horst and filling a low area between the
currently active lobes and the narrow strip of 1989 lava on which the old County Viewing trail was marked. Lava spreading
to the west is approaching a low area in the fault scarp which could provide a path for flows to reach the ocean.
Establishment of a robust ocean entry could slow the eastward advance of lava farther into Kalapana.
(2) Scattered lava flows also remain active about 1 km (0.6 mi) west and upslope of the Hwy 137 flow.
HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
Thursday, July 29, 2010 7:20 AM HST (Thursday, July 29, 2010 17:20 UTC)
Past 24 hours in Kalapana: Lava from the TEB vent flowed through tubes that carried lava down-slope to feed active
surface flows in two locations on the coastal plain: 1) scattered, small active lobes about 0.9 km (0.6 mi) to the west of the
highway 130/137 intersection and 2) several broader lobes which have not advanced significantly eastward since Tuesday
afternoon; three lobes have now topped Hakuma horst and two were entering the ocean yesterday.
Surface activity continued overnight as suggested by thermal anomalies recorded in MODIS and GOES-WEST imagery
overnight. The next Kalapana activity update will be posted by 4:30 pm H.s.t. today.
Kalapana Public Access Information from Hawai`i County Civil Defense: Kalapana Gardens is a private subdivision and
access will only be granted to subdivision residents. Private property borders highway 130 through Kalapana and no one is
allowed access off the highway easement. Hawai`i County Police will be monitoring the area.

Thursday, July 29, 2010 4:43 PM HST (Friday, July 30, 2010 02:43 UTC)
Lava from the TEB vent is flowing through tubes that carry lava down-slope to feed active surface flows in two locations on
the coastal plain:
(1) Geologic mapping this afternoon revealed minor activity on the north side of the lava that has been advancing toward
Kalapana Gardens, with very little eastward expansion. A few scattered lava breakouts on the north side of the flow
advanced up to 60 m (200 ft) in the past 24 hours, but most advanced less than 30 m (100 ft).
Lava continues to enter the ocean at two locations southwest of Kalapana Gardens, with numerous breakouts atop
Hākuma horst burning through the forest. The lava flow halfway between the two ocean entries (noted yesterday)
stagnated before reaching the ocean and remained inactive this afternoon.
(2) Scattered lava flows remain active about 1 km (0.6 mi) west and upslope of the Hwy 137 flow.
Public Access Information: Kalapana Gardens is a private subdivision and access will only be granted to subdivision
residents. Private property borders highway 130 through Kalapana and no one is allowed access off the highway
easement. Hawai`i County Police will be monitoring the area.
Lava from the TEB vent flowed through tubes that carried lava down-slope to feed active surface flows in two locations on
over highway 137 in Kalapana; the lead lobe made no significant eastward progress by early yesterday afternoon but, (see
status report from yesterday afternoon). Surface activity continued through dawn as suggested by thermal anomalies
recorded in GOES-WEST imagery overnight. Another update on Kalapana activity will be posted by 4:30 pm H.s.t.

Sunday, July 25, 2010 3:58 PM HST (Monday, July 26, 2010 01:58 UTC)
Lava from the TEB vent is flowing through tubes that carry lava down-slope to feed active surface flows in two locations on
the coastal plain:
(1) Lava continues to move northeast into the few remaining, topographically low kipuka at the west edge of the Kalapana
Gardens subdivision. There was a max of about 75 m (250 ft) of advancement in the past 24 hours. The advancing flows
set on fire the western-most house on highway 137 at about 3:30 am this morning, according to CD officials, leaving only
the roof and water tank visible by sunrise.
The lava, which had filled the depression on the northern edge of Hakuma horst, advanced through a low spot over the
horst about 600 m (2,000 ft) southwest of the leading flows. A narrow lobe crossed the horst and reached the ocean at
2:07 pm this afternoon according to residents.
Establishment of a robust ocean entry, in addition to the ongoing DI deflation at the summit and at the east rift zone vents
producing this lava, may temporarily slow eastward progress of the flows into Kalapana.
(2) Scattered lava flows also remain active about 1 km (0.6 mi) west and upslope of the Hwy 137 flow.

Monday, July 26, 2010 8:02 AM HST (Monday, July 26, 2010 18:02 UTC)
Past 24 hours in Kalapana: Lava from the TEB vent flowed through tubes that carried lava down-slope to feed active
surface flows in two locations on the coastal plain: a cluster of advancing lobes about 1 km (0.6 mi) behind and to the west
of the lead lobe advancing northeast over highway 137 into Kalapana Gardens subdivision; the lead lobe destroyed one
house early Sunday morning and filled the area between the north-facing scarp of Hakuma horst and highway 137; in one
location, a narrow lobe topped Hakuma horst and entered the ocean just after 2 pm yesterday (see yesterday afternoon's
status report and map). Surface activity continued through dawn but may be slowing as suggested by thermal anomalies
recorded in MODIS imagery yesterday and GOES-WEST imagery overnight. The next Kalapana activity update will be
posted by 4:30 pm H.s.t. today.

Monday, July 26, 2010 4:13 PM HST (Tuesday, July 27, 2010 02:13 UTC)
Lava from the TEB vent is flowing through tubes that carry lava down-slope to feed active surface flows in two locations on
the coastal plain:
(1) Lava continues to move eastward toward Kalapana Gardens, advancing about 130 m (425 ft) in the past 24 hours. A
nearly continuously active flow front is creeping into a remaining and topographically low kipuka at the western edge of the
subdivision, causing small brush fires and methane explosions.
Lava continues to enter the ocean, where it is beginning to form a small delta. It appears, however, that the amount of lava
reaching the ocean is less than the amount feeding the eastward-advancing flows. A few small breakouts near the western
end of Hakuma horst were making no headway toward the ocean.
(2) Minor scattered lava flows also remain active about 1 km (0.6 mi) west and upslope of the Hwy 137 flow.
Public Access Information: Kalapana Gardens is a private subdivision and access will only be granted to subdivision
residents. Private property borders highway 130 through Kalapana and no one is allowed access off the highway
easement. Hawai`i County Police will be monitoring the area.
The air was thick with smoke from burning
vegetation and asphalt. Flows here were
crossing Highway 137 and moving slowly
towards a residence.
More breakouts were active along Highway
137 today, with this lobe burning through a
grove of ironwood trees before reaching the
asphalt.

lava abutting the Hakuma horst, which is
directing flows towards the east. The fault
scarp extends about 2 meters above the level
of the lava here.
Tuesday, July 27, 2010 7:57 AM HST (Tuesday, July 27, 2010 17:57 UTC)
Past 24 hours in Kalapana: Lava from the TEB vent flowed through tubes that carried lava down-slope to feed active
surface flows in two locations on the coastal plain: a cluster of advancing lobes about 1 km (0.6 mi) to the west of the
highway 130/137 intersection and the lead lobes advancing northeast over highway 137 into Kalapana Gardens
subdivision; the most active lobes were advancing and filling kipuka left in the lava flows that destroyed the Kalapana small
delta and continued to feed a small amount of lava into the ocean but is not yet providing noticeable diversion of supply
from the advancing lobes to the northeast.
This morning, residents reported that the ocean entry was still producing a gas plume, that the lava continued to advance
overnight and has now consumed two of the three kipuka left between 2010 and 1990 lavas makai (seaward) of highway
130, and that there may have been new activity higher on the pali last evening. The switch to DI inflation at the summit and
the east rift zone vents may produce an increase in activity today or tomorrow. The next Kalapana activity update will be
posted by 4:30 pm H.s.t. today.
Kalapana Public Access Information from Hawai`i County Civil Defense: Kalapana Gardens is a private subdivision and
access will only be granted to subdivision residents. Private property borders highway 130 through Kalapana and no one is
allowed access off the highway easement. Hawai`i County Police will be monitoring the area.

Tuesday, July 27, 2010 4:47 PM HST (Wednesday, July 28, 2010 02:47 UTC)
Lava from the TEB vent is flowing through tubes that carry lava down-slope to feed active surface flows in two locations on
the coastal plain:
(1) Lava continues to move eastward toward Kalapana Gardens, advancing at most about 100 m (330 ft) in the past 24
hours. Lava is creeping into remaining kipuka at the western edge of the subdivision, and the flow front is 75 m (250 ft)
from the nearest structure. Activity observed this afternoon is less vigorous than that observed yesterday, and the
eastward advance of lava appears to have slowed.
Lava is still entering the ocean, forming a delta that continues to grow. About 500 m (550 yards) east of this ocean entry,
another flow overtopped the Hakuma horst, and, as of noon today, this lava was about 20 m (65 ft) from the ocean.
(2) Minor scattered lava flows also remain active about 1 km (0.6 mi) west and upslope of the Hwy 137 flow.
Public Access Information: Kalapana Gardens is a private subdivision and access will only be granted to subdivision
residents. Private property borders highway 130 through Kalapana and no one is allowed access off the highway
easement. Hawai`i County Police will be monitoring the area.

Wednesday, July 28, 2010 4:46 PM HST (Thursday, July 29, 2010 02:46 UTC)
Lava from the TEB vent is flowing through tubes that carry lava down-slope to feed active surface flows in two locations on
the coastal plain:
(1) The eastward advance of lava toward Kalapana Gardens is slow and sluggish compared to the past several days, with
a maximum expansion of only about 30 m (100 ft) since yesterday.
Lava is now entering the ocean at two locations southwest of Kalapana Gardens. The second ocean entry is approximately
545 m (600 yards) east of the initial entry, where lava reached the ocean on Sunday, July 25. About halfway between the
two ocean entries, another flow has overtopped Hakuma horst, and, as of noon today, this lava was about 75 m (250 ft)
from the ocean.
(2) Minor scattered lava flows also remain active about 1 km (0.6 mi) west and upslope of the Hwy 137 flow.
Public Access Information: Kalapana Gardens is a private subdivision and access will only be granted to subdivision
residents. Private property borders highway 130 through Kalapana and no one is allowed access off the highway

A narrow finger of lava reached the ocean
just after 2 pm yesterday. By this afternoon
through the thick steam plume. Lava also
remained active on the coastal plain, close to
residences in Kalapana.
The finger of lava that reached the ocean
yesterday took out numerous trees on its
path to the water. This coconut palm was one
of many burned and fallen.
Lava exited the tube at the sea cliff and
In the past day a second finger of lava
overtopped the Hakuma horst and pushed
through thick vegetation towards the ocean.
The flow front was less than 20 meters from
the sea cliff this morning. Along the margins
of this finger, lava triggered numerous small
fires, sending thick smoke through the forest
of hala trees and coconut palms.
The flows that reached the ocean on July 25
continued to build a small delta today.
The front of this small finger of lava was
almost to the sea cliff this morning, and was
burning through low brush along the
coastline.
Friday, July 30, 2010 7:49 AM HST (Friday, July 30, 2010 17:49 UTC)
Lava from the TEB vent flowed through tubes that carried lava down-slope to feed active surface flows in two locations on
the coastal plain: 1) scattered, small active lobes about 0.9 km (0.6 mi) to the west of the highway 130/137 intersection and
2) several broader lobes which have advanced less than 60 m (200 ft) toward the north; lava was actively entering the
ocean at two locations.

130, and burning through forest adjacent to
the coast. The burned remains of trees and
brush cover the surface of the new flows at
