Bali Governor Appeals to Refugees of Mount Agung Eruption .

23 SEPTEMBER 2017. Bali Governor, Made Mangku Pastika appealed to the refugees whose group is less than 200 inhabitants to join other refugees at the government-appointed evacuation post. The appeal was issued by Pastika after the status of Awas, Gunung Agung.
« This will facilitate the distribution of aid, whether food, health or other assistance needed, » Pastika said as he toured several refugee camps in Amlapura, Karangasem, Saturday (23/9).
According to him, the number of refuge points, causing difficulties for officers to record their existence. Therefore, groups of refugees who number less than 200 souls to immediately join the refugee posts that have been determined by the government. As in GOR Sweca Pura in Klungkung District, Refugee Post in Rendang and Sidemen, Ulakan, in Karangasem District, and Refugee Posts in Les and Tembok Village in Buleleng Regency.

Until Saturday (23/9) at 12.00 Wita, the number of refugees who have been recorded to reach 15,124 people spread in 126 points in all regencies / cities in Bali. The location of evacuation both in refugee posts that have been set by the government and the village halls, the field, as well as in the homes of the people who are considered safe.
The number one person in Bali also ordered that the public kitchen originally located at Tanah Ampo Port to be immediately transferred to the Refugee Post in Rendang.

He also had the opportunity to visit the refugees at UPT Rendang.
He asks people to calm down, not panic, and not easily believe in the unknown. « Our people expect to be attentive and listen attentively to the instructions of the sub-district or village chiefs, » said Pastika.

Copahue , Chile :

Special volcanic activity report (REAV)
Region of Biobio. 21 September 2017.12: 30 hours (local time).

The Chilean National Geological and Mining Service (Sernageomin) announces the following information, obtained through the monitoring equipment of the National Volcanic Monitoring Network (NVNV), processed and analyzed at the Southern Andes Volcanic Observatory ( OVDAS):

According to the IP cameras that monitor the Copahue volcano, an increase in the height of the gas column with presence of particulate matter from the main crater has been observed over the past few days. However, the energy levels of discrete and continuous seismic signals, as well as the absence of deformation of the volcanic building, represent a scenario that can be considered as its current base activity.


Since the beginning of the volcanic activity recovery in 2012, there have been numerous crises and periods of continuous emissions of particulate matter, which exhibited low intensities, as well as pressures and seismicity identical to those currently recorded, without showing a major escalation in the eruptive process. The latter are mainly associated with an increase in the level of energy and the presence of seismic activity. At present, there is a rise of a small magmatic body to more superficial levels, which affects the hydrothermal system and generates ash emissions and nighttime incandescence. This state of semi-stability can last for some time.

At the time of this report, the column remains fluctuating with low energy, reflecting the persistent activity in the volcanic system. This suggests that the system remains active but with passive emissions which, with their dispersion, can affect the proximal area of ​​the volcanic building.
Because of the above, the volcanic technical alert is maintained at the GREEN level with particular attention to its temporal evolution. It is recommended that preventive restrictions be applied to access an area adjacent to the crater within a radius of 1000 m, taking into account the possibility that the processes of smoking activity as reported in this report will still occur and with more vigor.
The Sernageomin continues with on-line monitoring and will inform in a timely manner of possible changes in the volcanic activity of the region.

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:
Kīlauea Volcano continues to erupt at the summit and from the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow continues to enter the ocean at Kamokuna. Firehose lava activity was reported this morning to have returned at the ocean entry delta. Surface flow activity persists on the upper portion of the flow field, on the pali, and in scattered areas of the coastal plain. These lava flows pose no threat to nearby communities at this time. Low rates of ground deformation and seismicity continue across the volcano.

Summit Observations:
Summit tiltmeters continue to recorded deflationary tilt. The lava lake surface was at 46 m (151 ft) below the rim of the Overlook crater when measured this morning. 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. Summit sulfur dioxide emission rates remain high.

Wispy fumes provided a clear view of the western wall of the Overlook crater this morning. Just above the lake surface (bottom of photo), a « bathtub ring » extends up the wall several meters, marking a recent high stand of the lake. Above that, a thick span of red, white and yellow rock is exposed in the crater wall. The colors originate from oxidation and alteration of older lava that filled Halema‘uma‘u in the 1960s and 1970s. Above the colorful rocks is an 8 m (26 ft) thick section of darker rock layers, which were formed by lava overflowing the vent rim in April and May 2015. The top of the photo shows the flat floor of Halema‘uma‘u, blanketed in a continuous layer of Pele’s hair.

Puʻu ʻŌʻō Observations:
Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from a small lava pond on the west side of the crater. There were no significant changes in seismicity over the past 24 hours and no significant change in measured ground tilt. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.

The Pu’u ‘O’o lava lake was once again very active, with bubbling over its entire surface. The plume of gas was blowing in a favorable direction, giving us a fairly clear view.

 

Lava Flow Observations:
The episode 61g flow is still active and entering the ocean at Kamokuna. Firehose lava activity was reported this morning to have returned at the ocean entry delta. Webcam images clearly show that surface lava flow activity persists on the upper portion of the flow field, on the pali, and in scattered areas of the coastal plain. The closest active lava on the coastal plain to the gravel road was 1.6 km from the road as measured on September 21. None of these flows poses a threat to nearby communities at this time.

Popocatépetl , Mexico :

23 September, 10.00 (23 September, 15.00 GMT).

Over the last 24 hours, the monitoring systems of the Popocatépetl volcano have identified 147 low-intensity exhalations. In addition, two volcano – tectonic earthquakes were recorded, one yesterday at 11:46 am, with a preliminary size of M1.8 and another today at 05:18 with a preliminary size of M2.4.
During the night there was no incandescence on the crater.
At the time of this report, the volcano was observed with low emission of water vapor and gas.
It is important to note that no significant increase was observed in the activity of the volcano that can be linked to the earthquake of magnitude M7.1, recorded on 19 September with an epicenter in the state of Puebla.
The Popocatépetl volcano is monitored 24 hours a day. Any changes in activity will be reported in a timely manner.

Update September 23, 5:20 pm (September 23, 10:20 pm GMT).

At 4:09 am and 5:08 am, two explosions were recorded with low vapor, ash and gas emissions. The height of the column was less than 2000 meters and dissipated in a preferential direction towards the northwest. This type of activity is considered in the yellow-level volcanic warning scenarios, step 2. It is important to note that no significant increase was observed in the activity of the volcano that can be linked to the earthquake land of magnitude M7.1, recorded 19 September with epicenter in the state of Puebla. Monitoring of the Popocatépetl volcano is ongoing 24 hours a day. Any changes in activity will be reported in a timely manner.
CENAPRED asked not to approach the volcano and especially the crater, due to the risk of falling projectiles.
The Popocatépetl volcanic warning semaphore is located in Amarillo Phase 2.
