Vent-fed `a`a lava flow from January 14

Vent-fed `a`a lava flow from January 14 surge on left; on right is tube-fed pahoehoe lava that oozed from a weakened part of tube that same evening. Main direction of spread for both lava flows is toward the viewer. Forest adjacent to flow in upper left corner killed and partly burned by heat from the lava. Pre-January `a`a forms isolated, more reddish-brown areas within expanse of the January 14 lava. Skylight into lava tube visible at lower right. Field of view about 500 m across center of photo.
