Rinjani, Indonésia :

The activity of Mount Barujari, located in the National Park of Mount Rinjani, Lombok, West Nusa Tenggara (NTB) increases.

On November 1, 2015 at 5:52 p.m., an eruption of Mount Rinjani (Barujari) amounted to 1500m above the crater Barujari and 3900m above the level of the sea. The wind was blowing toward the WestNorthwest .


The history of eruptive activity is characterized by explosive and effusive eruptions which the center of activity is the Barujari , located in the G. Rinjani caldera.
In the history of its activity, the eruption of Mount Rinjani indicate a potential hazard in the form of pyroclastic flows , lava, and ash fall. The areas potentially threatened by pyroclastic flows and ash fall are located inside the caldera, falling ash can also spread around Mount Rinjani depending on the wind direction.

The alert status of Rinjani is Level II (Waspada) since October 25, 2015. No community activities / visitor are allowed in the Rinjani caldera and within 3000m around the top of Barujari.

Kilauea, Hawaï:


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:
Eruptions continue at Kilauea Volcano’s summit and in its east rift zone at Pu’u ‘O’o. Summit deflationary tilt continues this morning. The lava lake level is roughly 70 m (230 ft) below the Overlook crater rim. Scattered breakouts remain active northeast of Pu’u ‘O’o, within about 7 km (4 miles) of the vent. There is no lava flow threat to nearby communities.

A time-lapse camera located in HVO’s observation tower captured these interesting images of Halemaʻumaʻu during an intense lightning storm at Kīlauea’s summit on October 16. Image captured at 11:43 PM.


Summit Observations:
The deflationary tilt at Kilauea’s summit that began yesterday morning continues. The lava lake level, after rising several meters has dropped during the past day and is roughly 70 m (230 ft) below the Overlook crater rim. During the past day, intermittently high tremor and associated spattering activity at the lake’s surface has been occurring. Summit sulfur dioxide emission rates averaged 3,400 metric tons per day for the past week.














 An inactive spatter cone on the floor of Pu’u ‘O’o crater releases sulfur dioxide, while serving as a window to the churning reservoir of lava within.












Pu’u ‘O’o Observations:
Web cam images this morning show no significant change in eruptive activity within the crater. Tilt measured at Pu’u ‘O’o, switched from inflationary to gentle deflationary Saturday night. No significant changes in seismicity have occurred. The sulfur dioxide emission rate from all East Rift Zone vents was about 150 metric tons per day when last measured on October 21, 2015.

June 27th Lava Flow Observations:
This morning, webcam images show that scattered breakouts remain active between about 2.2 and 6.4 km (1.4 and 4 mi) northeast of Pu’u ‘O’o There is no lava flow threat to nearby communities.

Piton de la Fournaise, La Réunion .

End of the effusive Phase on October 31 to 4:17 p.m.

From 4:17 p.m., October 31, the tremor recorded by the instruments of the Observatory has fallen sharply in the space of 2 minutes, announcing the end of the current phase effusive. At the time of writing this message, a slight degassing remains.

On Saturday, October 31 at 17:00, no more lava fountain activity or strombolian explosion is visible at the vent newly appointed Piton Kalla and Pele. The weather conditions remain good on-site, and the Piton Kalla and Pele remains observable from the path leading to the Piton de Bert.


We photographed the end of the eruption with a drone in a world exclusivity, lava fountains over 80 meters high suddenly gone before us and there is virtually nothing remains inside the eruptive cone.

To recall, in eruptive phase and no major change in the activity or in the recorded signals, the transmission frequency of detailed bulletins from the observatory is one by week.
