Kilauea, Hawai :
19°25’16 » N 155°17’13 » W,
Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Eruptive activity continues at Kīlauea Volcano’s summit and East Rift Zone. Seismic activity and deformation rates throughout the volcano are within background levels. Scattered lava flow activity continues on the June 27th lava flow field within about 6 km (4 mi) northeast of Puʻu ʻŌʻō. These flows currently pose no threat to nearby communities.
The lava lake remains active and circulating within Halemaʻumaʻu Overlook crater. Seismic tremor levels have been variable but within background values. Over the past 24 hours, slow inflationary tilt has resumed at the summit. The surface of the lava lake was 74.5 m or 244 ft below the Halemaʻumaʻu Crater floor late yesterday afternoon. The summit sulfur dioxide 24-hr average emission rate averaged 2300 metric tons/day over the period December 2 – 21.
The lava lake in Pu‘u ‘O‘o is visible in the lower right corner of the image. The gas plume shifted just long enough for us to get a peek at it!
Puʻu ʻŌʻō Observations:
Webcam images show persistent glow sources within the crater and high on the northeast rim. Seismic activity remains low. Puʻu ʻŌʻō tiltmeters recorded very little change in tilt over the past day. The sulfur dioxide emission rate from all East Rift Zone vents was about 260 metric tons/day when it was last measured on December 18.
June 27th Lava Flow Observations:
When not obscured by weather clouds, webcams show continued lava flow activity within the upper June 27th flow field within about 6 km (4 mi) of Puʻu ʻŌʻō. These flows are not currently threatening any nearby communities.

Popocatepetl, Mexico :
December 24 11:00 h (December 24, 17:00 GMT)
In the last 24 hours the seismic records of the monitoring system at Popocatépetl volcano registered 16 low-intensity exhalations, accompanied mainly by steam and gas emissions. Also were registered four explosions, yesterday at 16h07 pm and today at 00h43 , 00h44 and 08h50 .
During the night and early today was observed incandescence in the area of crater, which increased by episodes .
From the early hours of the morning until the time of this report, there has been a continuous emission of steam, gases and ashes .
CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments .
This type of activity is included within the scenarios Volcanic Traffic Light Yellow Phase 2.
