Kanlaon , Philippines :

 29 Mars 2016 19:00

At around 6:20 PM, an ash eruption occurred from the active crater of Kanlaon Volcano that lasted around 12 minutes based on seismic records. The event was accompanied by a booming sound heard in Sitio Guintubdan, Brgy. Ara-al and Brgy. Yubo, La Carlota City, Negros Occidental and Brgy. Pula Canlaon City, Negros Oriental. From the southeastern side of the volcano, the eruption plume was observed to have reached 1500m above the active crater. Traces of light ashfall were reported in Sitio Guintubdan, Brgy. Ara-al, La Carlota City, Negros Occidental.

kanlaon

Alert Level 1 status remains in effect over Kanlaon Volcano, which means that it is at an abnormal condition and is in a period of current unrest. The local government units and the public are reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as airborne ash from a sudden eruption can be hazardous to aircraft. DOST-PHIVOLCS is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned.

 

 

 

 BULLETIN 30 March 2016 8:00 A.M.

Two (2) minor eruption events occurred at Kanlaon Volcano’s active crater at around 6:20 PM and 7:18 PM of 29 March 2016 that lasted around 12 minutes and 25 seconds, respectively, based on visual observation and seismic recording. These events were recorded by the Kanlaon Seismic Network as explosion-type earthquakes. The first event was accompanied by a booming sound heard in Sitio Guintubdan, Brgy. Ara-al and Brgy. Yubo, La Carlota City, Negros Occidental and Brgy. Pula Canlaon City, Negros Oriental.

 

 

 

From the southeastern side of the volcano, the eruption plume was observed to have reached 1500 meters above the active crater. Incandescent ejecta apparently caused small bushfire at the upper slope as observed from La Castellana. Traces of light ashfall were reported in Sitio Guintubdan, Brgy. Ara-al, La Carlota City, Negros Occidental. The eruption was followed by two episodes of volcanic tremor from 10:38 PM 29 March to 00:26 AM 30 March and from 01:30 AM this morning to present (ongoing). Continuous GPS data as of 14 March 2016 indicated slight inflation of the Kanlaon edifice since December 2015.

Soputan, Indonesia :

Dated March 27, 2016, it was recorded two distant tectonic earthquakes (TJ) with a maximum range of 6 to 15 mm and a length of 22 seconds, two (2) earthquakes swarms (HB) with a maximum amplitude of 15 to 31 mm and a length of from 17 to 22 seconds, 15 avalanche earthquakes with a maximum amplitude of 4 to 33 mm.
Dated March 28, 2016 and until 18:00, it was recorded 1 local tectonic earthquakes (TL) with a maximum amplitude of 10 mm and a length of 9 seconds, 9 seconds of tremor, 6 avalanche earthquakes with an amplitude of more than 4 to 12 mm and a length of 10 to 32 seconds.

soputan
Based on visual observations of Soputan volcano, this one is usually visible and appears hazy. The main crater was observed emitting white smoke, thin to moderate, rising approximately 20-100 meters moving eastward. The temperature was 20 to 40 ° C
Seismic data from March 21 to March 28, 2016 have been dominated by the earthquake avalanche and earthquake swarms. The tremor volcanic earthquake (VA) were recorded the first time on March 21, 2016. The local and distant tectonic earthquakes were often recorded repeatedly. The earthquake of still high avalanche indicate the supply of magma from the interior to the surface. Every day the data of earthquake and RSAM data showed no decrease in seismic activity from March 21 until March 28, 2016.

Soputan

Based on visual and seismicity observations , and the potential threat of eruption of the Soputan, dated of March 28, 2016 18:00 the level of activity of Soputan is to LEVEL III (SIAGA).
Intensive monitoring is ongoing to assess the activity of Soputan well as to provide information on the danger of the eruption of Mount Soputan continuously so that people who live around Soputan understand.
If changes, decrease / increase , significant , of volcanic activities of Soputan, activity levels can be lowered / raised in accordance with the level of activity and threats.

Chikurachki ,  Northern Kuriles, Russia :

Current Aviation Color Code: ORANGE

Ash plumes is raising up to 3 km a.s.l. and extended about 50 km to the north-east from the volcano. Chikurachki volcano is not monitored with seismic instruments. KVERT has satellite monitoring and receives occasional visual observations of this volcano. KVERT continues to monitor Chikurachki volcano.

Ash explosions up to 32,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

 

Chikurachki

Chikurachki, the highest volcano on Paramushir Island in the northern Kuriles, is actually a relatively small cone constructed on a high Pleistocene volcanic edifice. Oxidized basaltic-to-andesitic scoria deposits covering the upper part of the young cone give it a distinctive red color. Frequent basaltic plinian eruptions have occurred during the Holocene. Lava flows from 1781-m-high Chikurachki reached the sea and form capes on the NW coast; several young lava flows also emerge from beneath the scoria blanket on the eastern flank. The Tatarinov group of six volcanic centers is located immediately to the south of Chikurachki, and the Lomonosov cinder cone group, the source of an early Holocene lava flow that reached the saddle between it and Fuss Peak to the west, lies at the southern end of the N-S-trending Chikurachki-Tatarinov complex. In contrast to the frequently active Chikurachki, the Tatarinov volcanoes are extensively modified by erosion and have a more complex structure. Tephrochronology gives evidence of only one eruption in historical time from Tatarinov, although its southern cone contains a sulfur-encrusted crater with fumaroles that were active along the margin of a crater lake until 1959.

Pavlof , Alaska :

55°25’2″ N 161°53’37 » W,
Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Based on a decline in ash emissions and seismicity, AVO lowered the Aviation Color Code to ORANGE and the Volcano Alert Level to WATCH yesterday at 6:01 pm AKDT (18:01 UTC). Periods of low-level ash emission and somewhat elevated seismicity persisted overnight, but decreased during the early morning hours. A satellite image from this morning at 6:25 am AKDT (14:25 UTC) showed minor ash emissions from the volcano.

 

pavlof

Clear web camera views from this morning confirmed intermittent low-level ash emissions at the volcano at maximum altitudes of 15,000 feet above sea level. Areas of drifting remnant ash from the initial energetic emissions on March 27 and 28 continue to be observed in satellite data over Bristol Bay and Interior Alaska. AVO received confirmed reports of trace ashfall (less than 1/32 in) that occurred yesterday near Dillingham in southwest Alaska. No significant ashfall is expected in communities at this time.

pavlof


Seismic activity remains elevated at levels above background and over the past 24 hours has been characterized by short tremor bursts. Occasionally, small explosions at the summit have produced airwave signals on the local seismic network. Infrasound (pressure sensor) signals from Pavlof were also detected on an array of sensors in Dillingham overnight.

Although the intensity of the eruption has diminished, it is possible for conditions to change at any time and more significant ash emissions may resume with little to no warning. AVO will continue to monitor the volcano closely.
