January 7, 2014 - Kīlauea Volcanoes East Rift Zone: 31 years and still erupting
January 3, 2014, marks the 31st anniversary of Kīlauea's ongoing East Rift Zone eruption. During its first 3 years, spectacular lava fountains spewed episodically from the 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 produced dramatic lava flows in past years, it has been relatively subdued in recent years, with mostly steady, but unusually weak, activity. Tim Orr, a geologist with the USGS Hawaiian Volcano Observatory, reviews highlights from the past 31 years and talks about recent developments on Kīlauea's East Rift Zone.
