Fuego, Guatemala :
After a week with a high level of activity on June 5 at 4 h25 Local time, the start of an effusive eruption with an explosion and a cloud of ash 5 km high, formed two lava flows of 400 and 700 meters long. At 8:00 pm on June 5, local reactivation of two fountains of lava to the west and south, which reached a height above the crater of 100 to 300 meters per reports this one, one feeding the flow West and the other the South flows were recorded.
A flow went towards the canyon of Santa Teresa with 600 meters long and the other to Canyon Trinidad, with a length of 1,200 meters .After 30 hours of strombolian eruption and lava effusion, activity ends, still leaving lava flows of 1300, 700 and 600 meters long, which are cooling . Current activity generates explosions, ash emissions with moderate impact, degassing and moderate explosion noises.
This eruption is the fourth of 2015. The main crater was deformed, leaving two cinder cones, visible from several points. Although the eruption is over, there is always the possibility of reactivation. Possibility of moderate lahars because it rains on the Fuego volcano at the moment, which usually causes these lahars in the Canyon Trinidad and eventually in the canyons of Las Lajas and El Jute. Therefore, INSIVUMEH recommends:
At CONRED: maintain the yellow alert phase II of Fuego volcano, also to take the necessary precautions for the passage of vehicles on rivers coming from Fuego.
At the Department of CIVIL AVIATION, it is recommended to take precautions with air traffic, because of the ash column. “

Popocatepetl, Mexique :
June 07, 11:00 h (June 07, 16:00 GMT)
In the last 24 hours the seismic records of the surveillance system of Popocatepetl volcano registered 27 low-intensity exhalations Through mounted cameras on the volcano, despite the cloudy conditions don’t allow observe volcano continuously.
Overnight an in the morning of today slight incandescence was observed over the crater increasing when some of main exhalations .
CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments .

Sinabung, Indonésie :
The Volcanology and Geological Hazard Mitigation Center (PVMBG) reported on Friday that the lava dome of Mount Sinabung in Karo, North Sumatra, was growing each day due to the volcano’s high level of activity.
An officer at the PVMBG’s Mt. Sinabung observation post, Deri Alhidayat, said quick growth in the lava dome could result in an additional volume of 100,000 cubic meters per day; slower growth yielded less volume.
Data at the PVMBG showed that the volume of Mt. Sinabung’s lava dome had increased from 3 million cubic meters on Wednesday to 3.1 million cubic meters the following day.
The old tongue of lava been eroded and collapsed, radically changing the lava dome structure.
“Today, we cannot detect the growth of the lava dome because Mt. Sinabung has been covered in thick fog until this afternoon,” Deri told The Jakarta Post on Friday, adding that the activity of the volcano was still high.
Deri said the speed of the growth of the lava dome depended on the volcano’s activity. The higher the activity, the bigger the growth.
As of Friday at noon, Deri said, his post had detected low frequency volcanic earthquakes and 106 avalanche earthquakes from Mt. Sinabung.
As of 6 a.m. on the same day, the volcano was detected to have spewed lava five times, which slid down its slopes for a kilometer to the south and 1.5 km to the southeast.
“It’s feared that these small avalanches of lava will trigger bigger avalanches. Caution is needed in this situation,” Deri said.
Asked whether the situation would affect the PVMBG’s recommendation regarding the radius of the areas to be evacuated, Deri said the current recommendation of 7 km had included 1 km to anticipate a bigger volume of lava.
He said that with a volume of 3 million cubic meters, the lava could reach 6 km down the slope of the volcano. That way, the 7-km radius recommendation was considered safe.
“But if the growth of the lava dome continues, it is possible that the recommended radius for the dangerous zone will increase,” Deri said.
The PVMBG had since Tuesday night increased the alert status of Mt. Sinabung to the highest level and recommended that people residing within a radius of 7 km from the crater of the volcano were evacuated.
As many as 2,727 people or 677 families were reported to have evacuated since then. They came from four subdistricts located to the south and southeast of the crater of Sinabung.
Karo Regent Terkelin Brahmana said that so far the evacuees’ needs for basic necessities had been fulfilled from the regency budget and private sector resources.
Separately, Karo Disaster Mitigation Agency (BPBD) head Subur Tambun said the agency was temporarily using ready-to-spend funds from the National Disaster Mitigation Agency (BNPB) from last year’s remaining budget of Rp 80 million (US$6,000) to fulfill evacuees’ needs for basic necessities for the next few weeks. –

Dukono, Halmahera, Indonésie .
Strong ash emissions continue from the volcano. Based on satellite data, VAAC Darwin reported that ash plume rose to 8,000 ft (2.4 km) altitude and extended 70 km NW this morning.
Reports from this remote volcano in northernmost Halmahera are rare, but Dukono has been one of Indonesia’s most active volcanoes. More-or-less continuous explosive eruptions, sometimes accompanied by lava flows, occurred from 1933 until at least the mid-1990s, when routine observations were curtailed. During a major eruption in 1550, a lava flow filled in the strait between Halmahera and the north-flank cone of Gunung Mamuya. This complex volcano presents a broad, low profile with multiple summit peaks and overlapping craters. Malupang Wariang, 1 km SW of the summit crater complex, contains a 700 x 570 m crater that has also been active during historical time.
