The NE spatter cone complex continued to feed the Kahauale`a 2 lava flow 8km (5mi) NE of Pu`u `O`o, the farthest advance since January 2014!
Colima (Western Mexico): Mild effusive and explosive activity continue at the volcano. A recent overflight made by the Civil Protection's fire fighting department of Jalisco (UEPCBJ) showed no significant changes in the summit area of the volcano. A flat mass of viscous lava is slowly extruding and overspilling on the western and southern sides of the upper cone, causing incandescent avalanches sometimes visible at night. Intermittent explosions with ash emission also continue to occur.
