Etna (Sicily, Italy): The activity of the volcano has remained similar to the previous days: so far, relatively weak but more or less steady ash emissions are occurring at the North-East crater, and tremor continues its slow rise. Whether this is a precursor to more vigorous activity (from the New SE crater?) remains to be seen probably in the coming days.
El Hierro (Canary Islands, Spain): No new significant earthquake activity has occurred over the past week, and deformation has stabilized on all stations: the latest crisis can be regarded as over (but it is probably only a matter of time until the next one).
Shiveluch (Kamchatka): A series of ash plumes to altitudes around 20,000 ft (6 km) from the volcano were reported by VAAC Tokyo, suggesting that the lava dome is currently in a relatively active phase with frequent explosions and/or rockfalls / pyroclastic flows.
Sakurajima (Kyushu, Japan): Following an unusually long interval with no real explosions, two small to modest vulcanian eruptions have again occurred on 6 January and today, with ash plumes reported to 10,000 ft (3 km) and 6,000 ft (1.8 km) altitude.
Suwanose-jima (Tokara Islands, Japan): Occasional stronger explosions at the volcano produce dark ash plumes rising up to 1-1.5 km altitude.
Rabaul (Tavurvur) (New Britain, Papua New Guinea): Rabaul caldera's Tavurvur cone was quiet during 16-31 December. White and occasionally blue vapor plumes rose from the crater. An explosion at 0732 on 22 December generated an ash-poor plume. Weak fluctuating glow was visible at night on 31 December. (Smithsonian/USGS Weekly Volcanic Activity Report)
Ulawun (New Britain, Papua New Guinea): RVO reported that activity at Ulawun was low during 16-31 December; diffuse ash plumes rose from the crater during 51-21 December, and white vapor emissions were visible during 22-31 December. (Smithsonian/USGS Weekly Volcanic Activity Report)
Marapi (Western Sumatra, Indonesia): The volcano (not to be confused with MErapi in Central
According to local newspapers citing PVMBG, the new eruptions were preceded by an increase in seismic activity under the volcano since 1 Januaryt and there were 5 explosions at 05:34, 05:53, 05:59, 06:12 and at 07:14 am local time, as well as some weaker ash emissions at 08:07. The current alert status of Mount Marapi, a popular climbing destination, still stays at level 2 (out of 4), but it is recommended not to approach the crater within a radius of 3 km. Pagan (Mariana Islands): Low-level unrest continued at Pagan during 27 December 2013-2 January 2014; seismicity remained above background levels. A robust steam-and-gas plume was occasionally visible in web camera images during the It may have produced a diffuse ash emission, but the webcam was not in operation at the time to |
