 crater lake closed for access

Thursday, October 8, 2015 9:39

Access to the volcano’s famous crater lake (and its sulfur mining area) has been temporarily closed by authorities. It seems that weak phreatic explosions occurred under the lake on 1 October, without causing damage or fatalities.
No further details are currently available.

The Ijen volcano complex at the eastern end of Java consists of a group of small stratovolcanoes constructed within the large 20-km-wide Ijen (Kendeng) caldera. The north caldera wall forms a prominent arcuate ridge, but elsewhere the caldera rim is buried by post-caldera volcanoes, including Gunung Merapi stratovolcano, which forms the 2799 m high point of the Ijen complex. Immediately west of Gunung Merapi is the renowned historically active Kawah Ijen volcano, which contains a nearly 1-km-wide, turquoise-colored, acid crater lake. Picturesque Kawah Ijen is the world’s largest highly acidic lake and is the site of a labor-intensive sulfur mining operation in which sulfur-laden baskets are hand-carried from the crater floor.

Many other post-caldera cones and craters are located within the caldera or along its rim. The largest concentration of post-caldera cones forms an E-W-trending zone across the southern side of the caldera. Coffee plantations cover much of the Ijen caldera floor, and tourists are drawn to its waterfalls, hot springs, and dramatic volcanic scenery.

Popocatepetl, Mexique :

October 08, 11:00 h (October 08, 16:00 GMT)

In the last 24 hours, through seismic records of the surveillance system of Popocatepetl volcano, recorded, on the one hand, 105 low-intensity exhalations. Apart from 18 isolated explosions, of medium intensity. The most important took place at 12:25 h yesterday, generated an ash column close to three kilometers high that winds dispersed the northeast. The burst launched ballistic fragments at distances up to 300 meters on the southern and southeastern slopes  .

Today also happens an explosive event at 6:22 h throwing ballistic-hot fragments less than 100 meters from the crater on the northeast slope  .
On the other hand, five minutes of low-amplitude harmonic tremor were registered.

Along yesterday´s nightfall was observed intense incandescence over the crater, increasing when the major exhalations . At the time of this report there is no visibility to the volcano, owing to weather conditions. Nevertheless, this morning Popocatépetl was seen free of emissions  .
Other monitoring parameters remain unchanged.

CENAPRED emphasizes that people SHOULD NOT go near the volcano,

Fuego, Guatemala :

The Fuego volcano, located 31 miles (50 kilometers) west of Guatemala City, began Thursday a new eruption with explosions and the release of ash, officials said.
According to the National Institute of Seismology, Volcanology, Meteorology and Hydrology (INSIVUMEH), the activity of the cone of 2,338 miles (3763 meters) high, started at 4:50 local time.
According to the scientific body, the effusive eruption maintaining an incandescent source that ejects lava flows 1,000 meters long south of the volcano.
There is also another stream to the north-west, 700 meters, he said.
The eruption, the eighth so far this year of the Fuego volcano, located between the departments of Chimaltenango, Escuintla and Sacatepequez, expels gases and ash 4,800 meters above sea level and forms a column of smoke that moves south and southwest at 12 kilometers away.

The Bulletin of the National Coordinator for Disaster Reduction (Conrad), with information from the volcanology institute said that in recent weeks, the volcano maintained a high activity level, which is reflected in the increased frequency and energy explosions.
At the moment, the activity poses no danger to nearby populations, according to INSIVUMEH. However, Conrad declared a yellow alert (prevention).
In addition, it was recommended to the Directorate General of Civil Aviation that the necessary precautions are taken to air traffic due to volcanic columns and ash particles in the atmosphere.

The authorities estimate that in the coming hours the volcano can increase the energy of its eruption.
Last February, the eruption of Fuego volcano had recorded a powerfull eruption,  forcing the authorities to declare a preventive alert and close the airport in the capital, because of the ash, which had also affected the tourist in the colonial city of Antigua, Guatemala.
