Abstract
The weather radar is generally employed to forecast the potential of hydrometeorological hazard. In the present paper, we focus on the application of C-band Doppler Weather Radar (CDR) to identify February 19th, 2018 Sinabung volcanic eruption and its dispersion by using a direct product in the form of CMAX (Column Max) retrieved from reflectivity factor (dBz). The distribution of reflectivity factor varies from the center of the eruption to the farther location indicating the dispersion of material size erupted by the Sinabung. Lapili which is larger material size with 48dBz tends to locate in the nearby volcanic area. The medium size of the material like coarse volcanic ash with 33 dBz of reflectivity was floating in the air and carried away by the wind. Meanwhile fine volcanic ash with 10 dBz of reflectivity flies a great distance along with the wind.
