Pu‘u ‘Ō‘ō and episode 61g flow

At Pu‘u ‘Ō‘ō on Kīlauea volcano's East Rift Zone, the ridge separating the main crater (above) and the west pit (below) has been subsiding over the past several months due to small rock falls and unstable ground. As the ground shifts, cracks along the ridge and on either side of it continue to open. The lava pond contained within the west pit (bottom) has risen several meters (yards) in the past month, and has produced overflows (darker lava) onto the floor of the pit as it rises. A small lava flow also erupted onto the floor of the main crater on March 25 and remained active through this evening (March 27). The crater flow is also darker in color, and visible in this image on the bottom half of the crater.
