January 8, 2013 - "Volcano Awareness Month: 30th Anniversary of Kīlauea's Ongoing East Rift Zone Eruption"
Jan. 3, 2013, marks the 30th anniversary of Kīlauea's ongoing East Rift Zone eruption. During its first three years, spectacular lava fountains spewed episodically from Pu'u 'Ō'ō vent. Since then, nearly continuous lava effusion has built a vast plain of pāhoehoe lava that stretches from the volcano's rift zone to the sea. Although the eruption has been relatively quiet during the past year, with mostly steady but unusually weak activity, it has produced some dramatic lava flows in past years. Tim Orr, USGS Hawaiian Volcano Observatory geologist, will review highlights from the past 30 years and talk about recent developments on Kīlauea's East Rift Zone.
