WebPlank, 2013). These approaches have revealed magma ascent rates that vary over orders of magnitude (0.1–30 m/s) for volcanism with a diversity of magma composition and viscosity, eruption explosivity, and depth resolution from source to vent (i.e. some tech-niques are sensitive in the shallow crust, while others may provide deeper constraints). WebDetermining the rate at which magma ascends during volcanic eruptions is challenging for several reasons because we cannot directly observe it and ascent …
