 The extrusive activity of the volcano has increased.

The local volcanologist Alexey Demyanchuk (volkstat.ru) carried out a field survey in the vicinity of the volcano a few days ago to report that the lava dome is growing again at intense values.
The active lava dome continues to produce frequent incandescent rock falls to the south-southeast, from at least two active areas of the huge dome. From time to time, ash plumes separate from block-and-ash flows (so-called phoenix clouds) as it descends the slope.
Emissions of gas and steam plumes with minor amounts of ash reached heights between 12,000 ft (3,700 m) and 15,000 ft (4,600 m) over the past few days.
As time passes and the dome continues to grow larger and larger, the risk of a sudden, potentially very large collapse event resulting in massive pyroclastic flows and explosions increases.

Important year based on some earthquake events between 2010 and 2011; Feb27,2010>Chile Earthquake_M8.8-06:34 UTC Sep3,2010>New Zealand Earthquake_M7.2-16:35 UTC March11,2011>Japan Earthquake_M9.0-05:46 UTC Sep15,2011>Fiji Earthquake_M7.3-19:30 UTC As maybe more interesting,amazing correlation as time of events that 4522 hours and one minute between Chile and New Zealand Earthquakes 4525 hours and 11 minutes between New Zealand and Japan Earthquakes 4525 hours and 44 minutes between Japan and Fiji Earthquakes Yes,we are witnessing a "perfect equidistance"  as 188 days ~!

Orfeus as European Infrastructure for Seismic Waveform in European Observating System on AlpArray Initiative is knowing on Seismologic Infrastructure Studies  into European Hinterland. New vision that shortly,expressing as "Synergy" With this aim,widening of organisational structure is basepoint.For this,emphasizing to powerfulness of a "mass approach" on observing of European Hinterland on opensource programming language As a conclusion of efforts in this field,a "Data Network Structure System" on Obspy&Python Programming Capabilities have developed. Shortly,reading on internet network of basedata &carrying-out by user of some data process steps.And next,presenting on some types of some conclusions... So,summarying as "Platform Structure" On earthquake researches,providing to international a "synergy" on ground researches besides earthquake via user networks at hinterland countries for establishing as powerful of inf
