  abstract = {{E}xplosive volcanic super-eruptions of several hundred cubic kilometres or more generate long run-out pyroclastic density currents the dynamics of which are poorly understood and controversial. {D}eposits of one such event in the southwestern {USA}, the 18.8 {M}a {P}each {S}pring {T}uff, were formed by pyroclastic flows that travelled >170 km from the eruptive centre and entrained blocks up to similar to 70-90 cm diameter from the substrates along the flow paths. {H}ere we combine these data with new experimental results to show that the flow's base had high-particle concentration and relatively modest speeds of similar to 5-20ms(-1), fed by an eruption discharging magma at rates up to similar to 10(7)-10(8)m(3)s(-1) for a minimum of 2.5-10 h. {W}e conclude that sustained high-eruption discharge and long-lived high-pore pressure in dense granular dispersion can be more important than large initial velocity and turbulent transport with dilute suspension in promoting long pyroclastic flow distance.},
