Mt. Sinabung Volcanic Activities Still High:

15 OCTOBER 2016. Volcanic activities of Mount Sinabung in Karo regency, North Sumatera is still high, according to the observation of a team from the Volcanology and Geological Disaster Mitigation Center (PVMBG) who was deployed to the location near the mountain.

Arif Cahya, a PVMBG official, said that in Medan and the mountain still erupts and spew hot clouds.

Therefore, the alert status of the mountain is still in place while the red zone is also still applied for the safety of the residents nearby, Arif said.

On Saturday morning at 1 am, officials reported that the mountain erupted and spew hot clouds. However, the height of the white clouds could not be monitored because the mountain was covered with mist.

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:
Kilauea Volcano continues to erupt at the summit and the Pu’u’O’o vent on its East Rift Zone. Inflationary tilt continues at the summit. The lava lake surface was 13 m (43 ft) below the floor of Halema’uma’u Crater as of yesterday morning. The 61g lava flow continues to enter the sea at Kamokuna posing no threat to nearby communities.

 

Summit Observations:
Tiltmeters at Kilauea’s summit continue to record inflationary tilt. The lava lake surface as of yesterday morning was 13 m (43 ft) below the rim of the Overlook Vent. Webcam views of the lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php.

Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Average daily summit sulfur dioxide emission rates ranged from 5,400 to 6,000 metric tons/day over the past week.

 

Pu’u’O’o Observations:
Webcam images over the past 24 hours show persistent glow at long-term sources within the crater. There were no significant changes in seismicity over the past 24 hours. Tilt remains flat. The sulfur dioxide emission rate from all East Rift Zone vents was about 310 metric tons/day when last measured on September 26.

Lava Flow Observations:
The 61g lava flow, extending southeast from Pu’u’O’o on Kilauea’s south flank continues to supply lava to the ocean at Kamokuna.

As a strong caution to visitors viewing the 61g flow ocean entry (where lava meets the sea), there are additional significant hazards besides walking on uneven surfaces and around unstable, extremely steep sea cliffs. Venturing too close to an ocean entry exposes you to flying debris created by the explosive interaction between lava and water. Also, the new land created is unstable because it is built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. In several instances, such collapses, once started, have also incorporated parts of the older sea cliff.

Finally, the interaction of lava with the ocean creates a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Katla , Iceland :

The National Commissioner of the Icelandic Police and the District Commissioner of Police in South Iceland have cancelled the Civil Protection Uncertainty level due to a possible eruption in the Katla caldera underneath the Mýrdalsjökull glacier.

After numerous earthquakes occuring in the time period between September 28th and October 2nd the seismic activity has now considerably reduced.

Seismic activity in Mýrdalsjökull is however the highest its been for years this autumn and experts are still keeping a close eye on the volcano.

Activity report of the Turrialba volcano
October 15, 2016, updated 5:00 p.m.

The magnitude of the tremor remained low with some discrete pulses of greater amplitude recorded from 9:08 to 9:25, 11:50 to 12:01 and from 12 h 36 to 12 40. Two other occurred at 15:25 and 3:45 p.m..

The volcano remained covered until 14:00 for partially emerge and it was possible to see a column of gas with low ash content that rose to just over 1500 above the crater, even when the amplitude of tremor remained low. The volcano is once again covered from 2:35 p.m.. He discovered again after 16:30 with an emission column directed to the Northwest, less than 1000 m above the crater.

Activity report of the Turrialba volcano
15/10/2016

At 6:28 p.m. local time, an eruption is recorded on the Turrialba volcano, with a column which is 1000 meters above the crater and up to 4340 m. (Altitude Meters) (14235.2 ft).

 


Activity duration: Ongoing.
Winds to the northwest.

No ash falls were not reported, no sulfur smell is reported.
