Sinabung - status of the eruption.

A point on the evolution of the eruption of Sinabung was done in the last detailed VSI report dated March 17, 2014 - for the period from 8 to 15.03.

At the seismicity level , the amplitude of tremor varies between 6 and 48 mm , with a dominant in the area 18-23 mm . Thirty-seven volcanic earthquakes ( VA ) were recorded between 8 and 15 March , and hybrid earthquakes related to fracturation and magma movements have disappeared ... The SO₂ flux variations between 300 and 598 tonnes per day indicates a continued magma supply : the intrusion continues without fracturation.

The instability of the lava dome /  lava tongue is rising, led by earthquakes associated with avalanches of blocks ( Guguran ), with an average of 223 per day.

Visual observation shows that the progression of the front of the tongue of lava is still valid ; on March 13 , it covered 2,421 meters from the top.
