Fig. 3.

Variation of volcanic gas components concentrations in the volcanic plume obtained by UAV measurement. The figure shows a part of the results obtained during the second flight on May 18, 2011. The slight differences of the peak positions are due to the different time lag of each sensor. The H2 sensor shows a long tailing due to the slow response of the sensor particularly in the low concentration range.
