Volcanic Activity Summary: On June 27, 2014, new vents opened on the northeast flank of the Pu‘u ‘O‘o cone that fed a narrow lava flow to the east-northeast. On August 18, the flow entered a ground crack, traveled underground for several days, then resurfaced to form a small lava pad. The sequence was repeated three more times over the following days with lava entering and filling other cracks before reappearing at the surface, in two of the cases farther downslope. Lava emerged from the last crack on September 6 and moved as a surface flow to the north. Between September 6 and 8, the flow advanced northward at a rate of 400 m/d (1,300 ft/d). In this way, the flow had advanced approximately 13.7 km (8.5 miles straight-line distance) from the vent, or to within 1.2 km (0.7 miles) of the eastern boundary of the Wao Kele o Puna Forest Reserve, by the afternoon of September 8. At the average rate of advancement of 400 m/day (1,300 ft/day) since September 6, we project that lava could flow from its current location either through the north part of Kaohe Homesteads, or to the north of Kaohe Homesteads, and reach the government road in P?hoa within 16-18 days if lava is not further confined within the cracks and down-dropped blocks within the East Rift Zone of K?lauea volcano. These estimates will be continually refined as we track this lava flow.

Kaohe Homesteads is located between the Wao Kele o Puna Forest Reserve and the town of P?hoa in the Puna District of the County of Hawai`i.

Recent Observations:
[Lava flow/dome] Lava flow advancing to the north at a rate of 400 m/day (1,300 ft/day).
[Volcanic cloud height] Unknown
[Other volcanic cloud information] Unknown

Hazard Analysis:
[Lava flow/dome] Lava Flow from Pu‘u ‘?‘? vent could reach the government road in P?hoa within 16-18 days.

Remarks: The Pu‘u ‘?‘? vent in the East Rift Zone of K?lauea Volcano began erupting on January 3, 1983, and has continued erupting for more than 31 years, with the majority of lava flows advancing to the south. Over the past two years, lava flows have issued from the vent toward the northeast. The June 27th flow is the most recent of these flows and the first to threaten a residential area since 2010-2011.

    Can I access a map tracing the lava flow from its first eruption to its current position on Cemetery Road and its projected trajectory? Possibly a map with dates of breakthroughs and/or changes in directions?
