The SO₂ camera: A simple, fast and cheap method for ground‐based imaging of SO₂ in volcanic plumes

SO 2 flux is widely monitored on active volcanoes as it gives a window into the hidden, subsurface magma dynamics. We present here a new approach to SO 2 flux monitoring using ultraviolet imaging of the volcanic plume through carefully chosen filters to produce images of SO 2 column amount. The SO 2... View More
