Lava Flow Front Emerges Again from Ground Crack, Continues Advancing Eastward

September 4, 2014

The surface flows at the front of the June 27th lava flow are fed by lava that is supplied through a lava tube that originates at the vent on Puʻu ʻŌʻō. This thermal image shows the lava tube close to Puʻu ʻŌʻō. Although the lava is several meters (yards) beneath the surface, it heats the surface sufficiently to be easily detected with thermal cameras. (USGS)

The following photos and videos were released by the Hawaiian Volcano Observatory (USGS) (Dated September 3, 2014 and September 1, 2014) . Note: these photos and videos were not taken in areas currently accessible to the public. (You can visit the official website of Hawai’i Volcanoes National Park for current information on the areas of Kilauea that are open to public). Click here to see photos from previous post.

CLICK PHOTO TO WATCH VIDEO: This Quicktime movie shows activity at the front of the June 27th lava flow. The flow front continues to advance eastward, with lava issuing out of a ground crack and spreading through dense forest, creating thick plumes of smoke. The farthest lava this afternoon was 1.3 km (0.8 miles) from the eastern boundary of the Wao Kele o Puna forest reserve. (USGS)

The June 27th lava flow remains active, with lava at the flow front issuing from a ground crack and advancing through thick forest, creating dense plumes of smoke. The farthest lava this afternoon was 13.2 km (8.2 miles) from the vent on Puʻu ʻŌʻō, and 1.3 km (0.8 miles) from the eastern boundary of the Wao Kele o Puna forest reserve. This forest reserve boundary is at the western boundary of Kaohe Homesteads subdivision, a portion of which is visible at the bottom of the photograph. (USGS)

One small portion of the flow front was quite vigorous, with an open stream of lava moving through the forest. (USGS)

This view looks east at the far end of the June 27th lava flow. In the center of the photograph is an isolated pad of lava which came out of ground crack last week. Further movement of lava within ground cracks has enabled the flow front to advance farther east, with lava issuing from a ground crack in the upper left portion of the photograph, where plumes of smoke mark the location of lava burning forest.

Map showing the June 27th flow in Kīlauea’s East Rift Zone as of September 3, 2014. The area of the flow as mapped on September 1 is shown in pink, while widening and advancement of the flow as of September 3 is shown in red. Last night, lava welled up out of the crack it was filling and spilled out onto the ground to feed new surface flows. As of early afternoon today (September 3), lava on the surface was 13.2 km (8.2 miles) from the vent and 1.3 km (0.8 miles) from the east boundary of the Wao Kele o Puna Forest Reserve. All older lava flows (1983–2014) are shown in gray; the yellow line marks the lava tube. (USGS)

The following videos were released by the Hawaiian Volcano Observatory (USGS) on September 1, 2014)

CLICK PHOTO TO WATCH VIDEO: The June 27th lava flow remains active at its leading edge, where lava is spreading out slowly into thick forest and also plunging into one of the many deep ground cracks that form Kīlauea’s East Rift Zone. This Quicktime video shows the activity near the eastern edge of the flow. This swiftly moving stream of lava was about 2 meters (yards) wide, and was visible down to about 30 meters (100 feet) depth in the crack, where it disappeared from view. (USGS)

CLICK PHOTO TO WATCH VIDEO: The Quicktime video begins with a view of the steaming ground crack, where lava is moving deep within the crack. As the view rotates west, lava can be seen on the surface burning thick forest. Finally, the camera focuses on the eastern edge of the flow, where lava is plunging into the deep ground crack. This swiftly moving stream of lava was about 2 meters (yards) wide, and was visible down to about 30 meters (100 feet) depth in the crack, where it disappeared from view. (USGS)
