Lava fountaining from the MLK vent

(February 9, 2005, 18:00:30 to February 10, 2005, 08:00:31) On February 9, 2005, an increase in lava discharge from Pu‘u ‘Ō‘ō, part of a longer term increase in effusion rate (Miklius and others, 2006), resulted in vigorous spattering and low fountaining from the MLK vent. Before the event, the tallest of the small complex of spatter cones over the MLK vent was about 6–7 meters high. This suggests maximum fountain heights of about 10 meters. The time-lapse camera was positioned on the south flank of the Pu‘u ‘Ō‘ō cone, about 70 meters from the erupting cone and about 25 meters upslope from passing lava flows. The prevailing wind direction was from behind the camera, which aided in keeping the camera relatively cool. Simultaneous heightened activity is also visible over the PKK lava tube, indicating that this was a surge through at least the local magmatic system.
