Eruption of Kīlauea Volcano in Hawaiʻi Sends Lava East of Puʻu ʻŌʻōOn June 27, 2014, several new fissures opened on the northeast flank of Puʻu ʻŌʻō, within the East Rift Zone (ERZ) of Kīlauea volcano, Hawaiʻi. Many short lava flows were erupted initially, but within days activity focused solely on the lowest elevation fissure, which subsequently built a shield and lava pond. On July 10, eruptive activity shifted to the next lowest fissure, and a lava flow began to advance continuously to the northeast. This lava flow eventually intersected a system of deep ground cracks along the ERZ on August 18. After repeatedly entering, filling, and exiting several ground cracks and spreading to the east-northeast, lava escaped the crack system on September 6 and resumed flowing northeast. Throughout September and October, the lava flows have stopped and started, and on October 25 at 3:15 AM, HST, the flow crossed Apa`a Street/Cemetery Road and advanced toward Pāhoa Village Road. The flow front is presently stalled, but breakout activity continues in areas upslope of the leading edge. Hawaiian Volcano Observatory scientists are vigilantly monitoring the eruption and advancement of the lava flow. Please check the HVO website for the latest information.
Information about Volcanic Eruption Northeast of Bárðarbunga Volcano in IcelandThe fissure eruption, which began early on 31 August 2014, continues. The eruption is not explosive and has not created an ash plume. For the most accurate and up to date information, visit the Icelandic Meteorological Office Bárðarbunga information webpage.
