February 18, 23:25 UTC, 10:25 Sakhalin Time (SKT), 2013.

Snow (Chirpoi Is.) - YELLOW
By the satellite data the thermal anomaly and weak steam-gas emission were observed on February, 14, 15.
During another days of a week it was cloudly on the volcano.

Ivan Grozny – YELLOW
By visual data in February, 16 the ash-gas emission was observed up to the height of 3 km above sea level.

Pu`u `O`o : significant and fast deflation

...Within the Pu`u `O`o crater, the southwestern spatter cone continued to issue a small amount of lava; at about 1 am, there was a large amount of lava issued from the south side of the northeast spatter cone that was largely out of direct view of our Webcam array; this early morning breakout also resulted in new breakouts on the Kahauale`a tube high on the northeast flank of Pu`u `O`o cone. The tiltmeter on the north flank of Pu`u `O`o cone recorded fluctuations with an abrupt 1.3 microradian drop accompanying the above-mentioned crater-floor activity. Seismic tremor levels near Pu`u `O`o remained low. The most recent (preliminary) sulfur dioxide emission rate measurement was 300 tonnes/day on February 12, 2013, from all east rift zone sources.
Outside the crater and across the northeast flank of Pu`u `O`o cone, multiple lava flow lobes, informally called the Kahauale`a flow, continued to be active northeast on older Pu`u `O`o flows north of Pu`u Kahauale`a to the base of the 2007 perched channel (visible in Pu`u `O`o East Thermal and North Webcams); it's too early to tell whether the early morning activity from the NE spatter cone, the source of the Kahauale`a flow, will affect the Kahauale`a flow progress...
