to movements of rocks/solidified lava inside the crater.
Gas measurements
Several measurements of gases have been done around and at the crater rim.
Walking across the lava field,
CO and SO2 have been measured with the personal sensors.
CO reached
values of 3 ppm, whereas SO2 up to 2.5 ppm.
MultiGAS instrument has been used for measuring concentrations of SO2, CO2, H2S and H2
