Slow-moving and far-travelled dense pyroclastic flows during the Peach Spring super-eruption
Pyroclastic flows of the 18.8 Ma Peach Spring Tuff super-eruption travelled >170 km and entrained substrate blocks up to ∼1 m diameter. Here, the authors show that these flows had a dense base and speeds of ∼5-20 m s−1, fed by an eruption discharging magma at rates up to ∼107-108 m3 s−1for at lea...

| Summary: | Pyroclastic flows of the 18.8 Ma Peach Spring Tuff super-eruption travelled >170 km and entrained substrate blocks up to ∼1 m diameter. Here, the authors show that these flows had a dense base and speeds of ∼5-20 m s−1, fed by an eruption discharging magma at rates up to ∼107-108 m3 s−1for at least 2.5-10 h. |
