Kiebesi ( Makian ) , Indonesia :

On the basis of instrumental and visual observations and the potential dangers of eruptions the level of activity of Gunung. Kie Besi, North Maluku was raised from the level I (normal) to the level II (Waspada) on March 7, 2016 at 10:00. The recommendation of PVMBG is to declare a hazardous zone with a radius of 1.5 km around the crater. People outside of this zone must remain calm, and always follow the recommendations of PVMBG and the advice from local  government / BPBD .

Makian volcano forms a 10-km-wide island near the southern end of a chain of volcanic islands off the west coast of Halmahera and has been the source of infrequent, but violent eruptions that have devastated villages on the island. The large 1.5-km-wide summit crater, containing a small lake on the NE side, gives the peak a flat-topped profile. Two prominent valleys extend to the coast from the summit crater on the north and east sides. Four parasitic cones are found on the western flanks. Eruption have been recorded since about 1550; major eruptions in 1646, 1760-61, 1861-62, 1890, and 1988 caused extensive damage and many fatalities.

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


Small vents in the southern portion of Puʻu ʻŌʻō crater have been active recently, and erupting new lava flows onto the floor of the crater. The light-colored flow in the center of the photograph was active this morning, and slowly spreading across the crater floor.


Activity Summary:
Kilauea Volcano continues to erupt at its summit and from its East Rift Zone. Weak lava flow activity continued within Pu’u’O’o crater. Scattered surface flows remain active on the ‘June 27th’ flow field within about 6.0 km (4 mi) of Pu’u’O’o and do not currently threaten any nearby communities. Seismicity and deformation are within normal levels throughout the volcano.

Summit Observations:
Kilauea Volcano continues to host a circulating lava lake at its summit which remained about 30 m (98 ft) below the rim of the Overlook crater. Spatter from the surface of the lava lake was intermittently visible from a webcam on HVO’s roof when the weather was clear. No significant ground tilt was recorded over the past day. Rates of seismicity continue at normal levels, with periods of increased tremor associated with spattering within the Overlook vent. The sulfur dioxide emission rate varied between 800 and 7,000 metric tons/day during the past week.



The West pit, as seen in this photo looking west, contains a small lava pond that is tucked partly back under the pit’s overhanging southwest wall. The walls are, in fact, overhanging most of the pit’s circumference, making the pit wider at the bottom than at the top.

Pu’u’O’o Observations:
Small lava flows from the south vents within Pu’u’O’o crater continued to ooze intermittently. No significant ground tilt was recorded on the north flank of Pu’u’O’o cone. Seismic activity remained at background rates. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons/day when it was last measured on February 16, 2016.

Pu’u’O’o has changed dramatically over the years. This map shows the configuration of Pu’u’O’o ‘s current crater (outlined in yellow) and vents (marked in red). The base image is a mosaic created from photographs captured during a helicopter overflight on January 19, 2016. The current crater, with a maximum width of about 290 m (317 yd), is nested within a much larger crater that was present in early 2011. The current crater is about 20 m (66 ft) deep and has distinct embayments at its northeast, northwest, and south sides. These embayments were pits when the current crater formed in mid-2014. A short distance west of the current crater is a 50-m- (~165-ft-) wide pit, informallly called the West pit, that contains a 25-m- (~80-ft-) wide lava pond. The source of the currently active June 27th lava flow is a vent on the northeast flank of Pu’u’O’o, about 250 m (273 yd) downslope from the crater rim.

June 27th Lava Flow Observations:
Webcam views show that scattered surface flow activity continued on the ‘June 27th’ flow field. All active flows are within about 6 km (4 mi) northeast of Pu’u’O’o and do not currently threaten any nearby communities.

Tungurahua , Ecuador :




The volcanic activity is moderate to high.
In the last 24 hours, the volcano has registered continued emissions of steam and gas at 2500 m heights, with a moderate load of ash that moved westward. These events were also accompanied by rumbling and jets of incandescent blocks that descend on the slopes up to 2000 meters below the crater.
A seismic tremor signal, associated with emissions of gases and ash is recorded.
So far there are reports of gray and white ash falls, fine, in the areas of Pillate, Bilbao, Choglontús, Pelileo.



From 11:00 (TL) yesterday until 11:00 (TL) today, 22 episodes of tremor emission (TREM) from a few minutes to an hour and 14 explosions (EXP) were recorded.

Observations of emissions and ash.
During the night he was heard several explosions were recorded as gunshots. At night, the volcano was semi-cloudy but a glow was observed with blocks that have fallen on the northwestern side to 2,000 meters below the crater and blocks on the northeast side, down up 1000 meters below the crater.


The explosion at 5:35 (TL) produced a vibration of windows and a movement of the earth. It was heard a loud cannonade.
In the morning hours, it could be seen a continuous emission of gases with a moderate load of ash to a height of 2000 m above the crater, moving toward the southwest.
Currently, there are reporting falls of fine and white ash in the areas of Pillate, Pondoa and Vazcún.
In addition, he has report to black ash fall in areas of Bilbao and El Manzano.

Rain and lahars: No report of rain or lahars.


The Tungurahua volcano erupted. A Dantestic image. This morning, we could measure the forces of nature. In an instant, everything was illuminated by lava, the explosion was of gigantic dimensions, light from the volcanic cone flowed like rivers of fire, a few seconds later came the sound impact. I felt the ground move under my feet and for a moment my heart beat with a strong message of self-preservation: « Go from here now. »

The technicians of the OVTIGEPN have made a tour on March 6, 2016 in Sector West of the Tungurahua volcano, in the communities of Choglontús and Manzano. Through the monitoring network of ash falls, accumulation was recorded at about 7700 g / m2 in the Choglontús sector since February 26, 2016. Throughout the tour, it was clear a large affectation of agriculture because of the ash, especially maize crops. This ash falls have further encouraged the relocation of livestock.

Copahue, Chile / Argentina .

The level of activity of the volcano is at:
YELLOW level, changes in the behavior of volcanic activity probable time for an eruption : weeks / months.

Based on the analysis of information obtained by monitoring equipment and monitoring of the volcano, the Servicio Nacional de Geologia y Mineria (SERNAGEOMIN) Volcanológico Observatorio de Los Andes del Sur (OVDAS) announces:
During this period, twenty-six (26) seismic events including nine (9) who were classified as volcano tectonic (VT) associated with rock fracturing processes were recorded.
Similarly, seventeen events (17) associated with the fluid dynamics within the volcanic edifice, which fourteen (14) were identified as long-period earthquakes (LP) and three (3) as very long period events (VLP) were recorded.
As for the VT type of seismicity, their local magnitude (ML) were lower, on the order of M 1.7  , with locations widely dispersed  . The higher energy event was located on the North-East side (ENE) at 10 km of the crater El Agrio  with a depth of about 7 km.

In connection with the LP-type events, they have a reduced displacement values (DRC) under 1.5cm2. Seismicity of VLP types presented lower displacement values (DRC) of 7.0cm2, mainly located around the active crater with epicentral distances of less than 3.5 km.
During the month, there was a constant tremor signal, mainly associated with particulate emissions (gases and ash) from the crater El Agrio, which recorded DRC values with a rising trend, with values calculated below 5cm2values considered as intermediate for this volcano.

The dominant frequencies are concentrated in a bandwidth between 1.0 and 2.0 Hz.
IP cameras installed near the volcano recorded the constant emission of material from the active crater (El Agrio), accompanied by incandescence.
These emissions were characterized mostly by a gray color, showing the presence of particulate matter.
The maximum height measured during this period was 1,250 m above the active crater (El Agrio).


With satellite images, the distance reached by the ash cloud was observed up to 100 km from the El Agrio crater with directions preferentially to the southeast and east.
From the data obtained from three (3) GNSS stations that monitor the deformation of the surface of the volcano, it is observed that movements in both horizontal and vertical are minimal, the speed calculation is close to zero.

The sulfur dioxide emission (SO2) recorded on the Copahue volcano by the team DOAS (Differential Optical Absorption Spectrometry), Triplets Station, located 5 km eastnortheast of the active crater, presented a monthly average value of 1,125 ± 176 t / day and a maximum value observed during the second fortnight of 4264 t / day, registered on 25 February.
The average flow is considered at normal levels for this volcano.

Images published by the Group Sulphur dioxide (instrument to monitor ozone and NESDIS (National Environmental Satellite, Data and information – IMO Group http: // satepsanone.nesdis show no significant changes in the volcano area for SO2 emissions in the atmosphere.
Thermal radiation released by the MODVOLC (Moderate Resolution Imaging Spectroradiometer) MODIS on its website ( and Mirova (Middle InfraRed Observation of volcanic activity) on its website (http : / /, surveillance systems that indicate significant changes in surface temperature, shows no thermal warning reported in the area associated with the volcano.

According to the monitoring indicators described  above  , it follows that the activity related to the interaction of a magma body of small volume and the hydrothermal system continue, without unbalancing the system.
This activity may continue for a long period of oscillating manner, without excluding specific increases related to small phreatic explosions and / or low strombolian activity. Therefore, it is considered that, immediately next to the emission center , there is a high risk area and therefore an access restriction is recommended, within 1.5 km  around the crater El Agrio, and maintaining the level of technical  alert at level Yellow .
