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

Activity Summary:
Eruptions continue at Kilauea Volcano’s summit and East Rift Zone. The lava flow to the southeast of Pu’u ‘O’o continues to be active on the coastal plain. The flow does not pose a threat to nearby communities. The lava lake at Halema’uma’u Crater continues to circulate and spatter. The summit tilt reversed, begining an inflationary trend late yesterday. Low rates of seismicity are observed across the volcano.



Summit Observations:
Tiltmeters at the summit of Kilauea recorded a switch to inflationary tilt that began at around 9 PM yesterday. The level of the summit lava lake at Halema’uma’u which had been dropping, once again began to rise, and as of this morning stood at 34 meters (112 feet) below the floor of Halema’uma’u. Minor fluctuations in seismic tremor related to variations in lava lake circulation and spattering continue. Sulfur dioxide emissions from the summit vent over the past week ranged from 3,900 to 7,300 metric tons/day.



Pu’u ‘O’o Observations:
HVO webcams show several incandescent vents on the floor of Pu’u ‘O’o crater, as usual. There were no significant changes in seismic activity at Pu’u ‘O’o. A tiltmeter on the north flank of Pu’u ‘O’o that had been recording gentle deflationary tilt saw that tilt flatten out Monday evening. The sulfur dioxide emission rate from all East Rift Zone vents when last measured on July 8 was about 280 metric tons/day.

Lava Flow Observations:
The 61G lava flow, southeast of Pu’u ‘O’o continued to be active on the coastal plain on Kilauea’s south flank. HVO had no field crews on the flow field on Monday but is planning fieldwork there today. When mapped on Sunday afternoon, the flow front had advanced only 40 m (44 yards) since Saturday’s measurements; at that time, the flow front was still about 1 km (0.6 miles) from the ocean. Bright incandescence is visible in the overnight webcam views of the active lava flow field, marking lava tube skylights above the pali.

Popocatepetl , Mexico :

July 12, 11:00 h (July 12, 16:00 GMT)

Over the past 24 hours, the monitoring system of Popocatépetl volcano registered 75 long-period earthquakes (LPs). Also were detected 2 small volcanic explosions by infrasound microphones and seismometers . Also were recorded 600 minutes of low-amplitude harmonic tremor and one volcano-tectonic earthquake with duration magnitude Mc=1.8.




At night, webcam images show some glow sources within the crater .
At the time of this report the weather conditions not allow observing the volcano continuously, but yesterday and today morning it was observed a continuous emission of steam and gas in northwest direction.

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.

Sheveluch , Kamchatka :

56.64 N, 161.32 E;
Elevation 10768 ft (3283 m),
the dome elevation ~8200 ft (2500 m)
Aviation Color Code is ORANGE

A growth of the lava dome continues (a viscous lava flow reveal in the northern its part), strong fumarole activity, ash explosions, hot avalanches and an incandescence of the dome blocks and hot avalanches accompany this process. A hot avalanche sent ash up to 3.5 km a.s.l. at 2117 UTC on 12 July, 2016.



Hot avalanche from western flank of the lava dome of Sheveluch volcano sent ash up to 3.5 km a.s.l. on 12 July, 2016.

Satellite data by KVERT showed a thermal anomaly over the lava dome.
Explosive-extrusive eruption of the volcano continues. Ash explosions up to 32,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.
Distance of ash plume/cloud of the volcano: 6 mi (10 km)
Direction of drift of ash plume/cloud of the volcano: NNE
