Merry Christmas to all. That these moments bring peace in your hearts, and on this poor planet which really need.


 Kanlaon, Philippines :

At around 2:57 PM, an ash explosion occurred at Kanlaon Volcano based on seismic records. An intensity II earthquake was reportedly felt at Sitio Guintubdan, Brgy. Ara-al, La Carlota City. The explosion event was not visually observable due to thick clouds covering the summit but was accompanied by a rumbling sound heard in Brgy. Cabagnaan, La Castellana, Sitio Guintubdan, Brgy. Ara-al and Brgy. Yubo, La Carlota City. Traces to light ash fall were reported at Sitio Guintubdan, Brgy. Ara-al, Brgy. Haguimit, and Brgy. La Granja, La Carlota City.



Today , Kanlaon Volcano’s seismic monitoring network recorded six (6) volcanic earthquakes during the past 24 hours.

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.





Bromo, Indonésia :

An increase in volcanic activity at Mount Bromo in East Java left at least 28 villages smothered in ash, but is still not considered severe enough to warrant an evacuation, officials say.
The volcanic ash has damaged crops and forced residents to remain indoors. Bromo has been active for some time, but began showing elevated signs of volcanic activity last month, throwing columns of ash up into the atmosphere.
On Tuesday, it began spewing lava, which was only visible at night due to the thickness of the ash plume.



Officials say they are bracing for a potential evacuation of the more than 30,000 residents living around the volcano. They have already declared a 2.5-kilometer exclusion radius around Bromo’s crater and closed off hiking trails on the nearby Mount Semeru that could be affected by the hot gases and ash from Bromo.
“We have set up signs to help with the evacuation process,” Dwijoko, the head of the local disaster mitigation agency, or BPBD, said on Wednesday.
Ahmad Suban, the head of the Bromo observation post, said the volcano was expected to continue spewing lava for the next two months.

Copahue, border Chile / Argentina :


37.856°S, 71.183°W
Elevation 2953 m

Based on satellite and webcam views, the Buenos Aires VAAC reported that during 18-20 December steam and gas emissions with minor amounts of ash rose to altitudes of 3-3.6 km (10,000-12,000 ft) a.s.l. Plumes drifted N on 18 December and 55-150 km SSE and SE on 19 December. During 20-22 December the webcam recorded continuous ash emissions drifting short distances.


Volcán Copahue is an elongated composite cone constructed along the Chile-Argentina border within the 6.5 x 8.5 km wide Trapa-Trapa caldera that formed between 0.6 and 0.4 million years ago near the NW margin of the 20 x 15 km Pliocene Caviahue (Del Agrio) caldera. The eastern summit crater, part of a 2-km-long, ENE-WSW line of nine craters, contains a briny, acidic 300-m-wide crater lake (also referred to as El Agrio or Del Agrio) and displays intense fumarolic activity. Acidic hot springs occur below the eastern outlet of the crater lake, contributing to the acidity of the Río Agrio, and another geothermal zone is located within Caviahue caldera about 7 km NE of the summit. Infrequent mild-to-moderate explosive eruptions have been recorded at Copahue since the 18th century. Twentieth-century eruptions from the crater lake have ejected pyroclastic rocks and chilled liquid sulfur fragments.
