Kilauea's lava flow burns its first house in Pahoa, Hawaii

Kilauea's lava flow burns its first house in Pahoa, Hawaii

According to Hawaii County Civil Defense update issued 22:15 UTC on November 10, the front of Kilauea's lava flow remains approximately 150 meters (480 feet) from the Pahoa Village Road. 

​An upslope breakout in the area of Apa’a Street near the cemetery had entered a private property yesterday morning and at approximately 21:55 UTC (11:55 HST) the residential structure or house was ignited by the advancing flow.

There is no threat to any other properties at this time, Civil Defense said.

The evacuation advisory for those residents down slope of the flow will continue and residents will be kept informed of the flow status and advancement.

The Pahoa Village Road between Apa’a Street and the Post Office Road will remain closed and limited to area residents only. In addition, Civil Defense and public safety personnel will be operating in the area round the clock to maintain close observations of flow activity.

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base at 1:13,000 scale to show the area around the front of the June 27th lava flow. The area of the flow on November 7, 2014, at 3:30 PM is shown in pink, while expansion of the flow as mapped on November 10 at 10:45 AM is shown in red. The latitude and longitude of the front of the narrow finger of lava advancing toward Pāhoa was 19.49590, -154.95256 (Decimal Degrees; WGS84).

In the 2.5 km (1.5 mi) upslope of Apaʻa St. / Cemetery Road, minor expansion of the flow field has occurred over the weekend, HVO reported in their latest update.

The most significant activity on the entire flow field was a narrow finger of lava that has advanced downslope from the wide portion of the flow just above the narrow gulley through which lava advanced toward Pāhoa more than two weeks ago. That finger was about 700 meters (765 yards) above the transfer station as of late Monday morning.

Summit tilt was steady for most of Monday morning, but a period of inflation began at about 14:00 HST, with a commensurate rise in lava level within the summit eruptive vent.

Active areas include regions just downslope and upslope of the transfer station, and a new lobe of lava, marked by a smoke plume at the upper right of the photo, is moving to the northeast approximately 750 meters (820 yards) above Apaʻa Street / Cemetery Road.

Geologic summary

Kilauea volcano, which overlaps the east flank of the massive Mauna Loa shield volcano, has been Hawaii's most active volcano during historical time. Eruptions of Kilauea are prominent in Polynesian legends; written documentation extending back to only 1820 records frequent summit and flank lava flow eruptions that were interspersed with periods of long-term lava lake activity that lasted until 1924 at Halemaumau crater, within the summit caldera.

The 3 x 5 km caldera was formed in several stages about 1500 years ago and during the 18th century; eruptions have also originated from the lengthy East and SW rift zones, which extend to the sea on both sides of the volcano. About 90% of the surface of the basaltic shield volcano is formed of lava flows less than about 1100 years old; 70% of the volcano's surface is younger than 600 years. A long-term eruption from the East rift zone that began in 1983 has produced lava flows covering more than 100 sq km, destroying nearly 200 houses and adding new coastline to the island. (GVP)
