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
Eruptions continue at Kilauea Volcano’s summit and East Rift Zone. Seismic activity and deformation rates throughout the volcano are within background levels. East rift zone webcams show a new fuming, incandescent, but otherwise inactive, spot on the east rim of Pu’u ‘O’o crater and persistent scattered activity on the June 27th lava flow field within 6 km northeast of Pu’u ‘O’o vent. Lava flow activity poses no threat to nearby communities.
The lava lake remains active and circulating within Halema’uma’u Overlook crater. Seismic tremor levels have been variable but within background values. Tiltmeters resumed recording weak deflationary tilt overnight and the lava lake surface fell several more meters. Summit sulfur dioxide emission rates averaged around 4,200 metric tons/day for the week ending December 1.
Pu’u ‘O’o Observations:
Webcam images still show the new incandescent, fuming source on the east rim of the crater mentioned in yesterday’s update (far right edge of PNcam view). Seismic activity remains low. Pu’u ‘O’o tiltmeters recorded slightly more than one microradian of deflationary ground tilt since noon on December 07. The sulfur dioxide emission rate from all East Rift Zone vents was about 280 metric tons/day when measurements were last measured on November 30, 2015.
June 27th Lava Flow Observations:
Webcam views confirm continued activity mostly within the Pu’u ‘O’o flow field with minor burning along the forest edge. Active flows persist within roughly 6 km (4 mi) of Pu’u ‘O’o and are not threatening any nearby communities.

Bromo, Indonesia :
Authorities in East Java have ordered the closure of an airport until at least Saturday morning, following a volcanic eruption blowing ash around the region.
All flights out of and into Abdulrachman Saleh Airport in Malang were cancelled as of 9:30 a.m. on Friday, with authorities only planning to resume operations after 24 hours, conditions permitting.
Affected airlines have had to refund tickets, reschedule flights, or bus passengers to Surabaya, a two-hour drive away, to catch a flight from Djuanda Airport.
The closure was ordered after Mount Bromo, some 50 kilometers east of Malang, erupted, sending a thick column of volcanic ash up into the atmosphere.
Volcanic ash can damage jet engines, and a series of eruptions at other volcanoes this year have resulted in multiple and lengthy closures, particularly of Bali’s Ngurah Rai.
The VSI rating, based on the evaluation of the monitoring team, increased tremors, volcanic earthquakes, and the amplification of RSAM graphics (Realtime measuring seismic amplitude). Prohibition of entering the area with a radius of 2.5 km.

Ubinas, Peru :
The Volcanological Observatory Ingemmet (OVI) warned that the eruption process of Ubinas volcano, located in the Moquegua region, and continues activity may slightly increase in the next few days or mild to moderate explosions occur.
According to the monitoring of last week, experts commented that the seismic activity was dominated by massive earthquakes rate Volcano Tectonic (VT) that are associated with the fracturing of rocks within the volcano.
It has also been sporadically Hybrid types identified events associated the possible rise of magma. Specialists also detected slight bluish continuous emissions and gases containing water vapor emissions reached up to 1,100 meters above the crater rim of the volcano.
It is very possible that the increase of internal pressure stages (days: 29 October, 19 November and December 5) are in connection with rock fracturing produced by ascending magma movement, in pulses, with minimal resistance through the conduit, to very superficial volcanic levels. Low to moderate thermal anomalies in the registration thresholds (30 October–19 November and 5 December) were detected.
