Movie of the complete growth of the 2018-2019 lava dome of Merapi volcano (Indonesia) done from thermal images of Somerapi1.




Movie of the complete growth of the 2018-2019 lava dome of Merapi volcano (Indonesia) done from visible images.




Additional photographs of the lava dome and the monitoring stations




Movie of the last weeks of the lava dome growth done with anaglyphs calculated from the stereoscopic images of Somerapi1 and 3 (use blue and red glasses to see the relief).


 

Code used with the software Matlab.
(1) viscous_profile_3D.m shows how the viscous profiles are calculated to relate the volume rate with the surface velocities.
(2) VolcFlow_phase1_Fig7a and VolcFlow_phase2_Fig7b were used for Fig. 7. They must be used with Matlab and VolcFlow. Download VolcFlow here ( lmv.univ-bpclermont.fr/volcflow/), run VolcFlow in the command window of Matlab and load the input files.



Weather station data of Pasar Bubar, close to the summit. The data cover the whole dome emplacement. No correlation has been identify between rainfalls and collapses




Details of the calculation of the cohesion of the lava dome and of the volume rate estimation from the measurement of the surface velocities.
