Soputan, Indonesia :

The intensity of the eruption of Mount Soputan in Southeast  , South Minahasa region, and  Minahasa   has been further intensified until Tuesday (01/05/2016) afternoon.
But the eruption columns are not visible from the monitoring station due to the overcast sky.
According to one observer, Asep, the conditions are similar to the eruption of 2011. These events, because of strong winds, have resulted in the ash fall on the airport Sam Ratulangi.

State-owned airport operator PT Angkasa Pura (AP) I authorities shut down Sam Ratulangi International Airport in Manado, North Sulawesi starting from 7:30 p.m. local time on Tuesday to about 6 a.m. on Wednesday because of volcanic ash from the eruption of Mount Soputan, which was dangerous to aircraft.
The general manager of the AP I office at Sam Ratulangi Airport, Halendara Waworuntu, said the closure was done for the safety of passengers, since the volcanic ash had spread over the airport and its surrounding areas, disrupting flights.

“We needed to close the airport because of the volcano’s activity, which had affected flights,” said Waworuntu. He said it was possible for the office to extend the closure if Mt. Soputan continued to blow volcanic ash over the airport.
Waworuntu said AP I authorities would always be on 24-hour alert to anticipate the impacts of the volcanic eruption on airport activities while they continued to receive reports on the situation in the area.

Around 2:17 p.m., HST, on January 2, a rockfall from the east rim of the Overlook vent within Halemaʻumaʻu Crater at the summit of Kīlauea impacted the lava lake, generating a small explosive event captured by HVO webcams.


Activity Summary:
Eruptive activity continues at Kilauea Volcano’s summit and East Rift Zone. Seismicity and deformation rates throughout the volcano are largely at background. Scattered lava flow activity continues on the June 27th lava flow field within about 6 km (4 mi) northeast of Pu’u ‘O’o. These flows currently pose no threat to nearby communities.

In this photo of Kilauea Volcano’s summit lava lake, the light-colored rock in the vent wall to the left of the spattering lava shows were a rockfall occurred on January 2. The shadow of the gas plume appears as a brown streak perpendicular to the dark-colored lava on the floor of Halema’uma’u Crater. HVO and Jaggar Museum are visible on top of the caldera wall (upper left)..

 

Summit Observations:
The lava lake remains active within the Halema’uma’u Overlook crater. Summit tiltmeters recorded continuing inflationary tilt over the past 24 hours. The surface of the lava lake rose slightly with the inflation and was about 28 m (92 feet) below the floor of Halema’uma’u Crater this morning. Seismic tremor has been weakly variable, reflecting small changes in the vigor of spattering on the lava lake. For the period December 22–29, the summit sulfur dioxide emission rate averaged 1300 metric tons/day.

Pu’u ‘O’o Observations:
Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and high on the northeast flank of the cone. Seismic activity remains low at Pu’u ‘O’o, and tiltmeters recorded no significant inflationary or deflationary tilt (tilt was flat). 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.

 


This picture of a Quicktime movie shows the same rockfall as captured by the USGS Hawaiian Volcano Observatory webcam perched on the rim of Halema’uma’u Crater. Note the fragments of molten lava flying toward the camera—just one of the hazards that led to the closure of this area.


June 27th Lava Flow Observations:
Webcam images show continued surface flow activity on the June 27th flow field, with smoke plumes where lava is igniting forest . The most distal active lava is about 6 km (4 mi) northeast of Pu’u ‘O’o and is not currently threatening any nearby communities. The most proximal active lava is a small breakout from the lava tube on the north flank of Pu’u ‘O’o.

Ubinas , Peru :

LP type of earthquakes associated with fluid movement, maintain low levels, and decreased slightly compared to the previous week. They were observed on the average of 65 LP / day. Similarly, the energy of this type of low seismicity is maintained.
Regarding the activity of hybrid-type earthquakes, linked to the rise of magma, they have increased slightly, showing in this period analyzing two peaks of high seismic activity (30 hybrids in one day). It was, on average, 17 hybrid recorded daily. The hybrid energy values are low
The type of seismicity VT (fracture type earthquakes) again show an increase in the number of earthquakes observed on average with 117 VT / day.The energy values are low and show an average of 1 MJ / day.

 


During this period (December 29, January 4), and observing the images captured by the camera Campbell Scientific IGP, it has been possible to continue to enjoy the bluish gas emissions (magmatic gases) sporadically, with low density .
The maximum height reached by emissions was 1800 meters above the base of the crater. In this period, there was the expulsion of ash.
Temperature anomalies: The Mirova system (monitoring hot spots on the surface of the crater – www.mirovaweb.it) continues to detect temperature anomalies for the period, with a maximum of 4 MW. Note that, between November and December the number of thermal detections increased, including two 10-megawatt peaks, indicating the presence of a warm body to the surface of the crater.
Anomalies SO2: The satellite system « EOS Aura » GSDM-NASA (monitoring the density of SO2 gas – http://so2.gsfc.nasa.gov/) did not notice any major anomalies in the density values SO2 gas during this period.
