Cadamosto Seamount
- ... that past eruptions of Cadamosto Seamount dispersed volcanic ash underwater over thousands of square kilometres? Two widespread (> 3100 km2) phonolitic tephra layers (C1 and C7) of 0.12 and 0.21 km3 volume (VEI 4) are geochemically associated to the Cadamosto seamount, indicating that explosive eruptions of phonolitic composition can occur at > 1400 m water depths. The vesicle-poor, hyaloclastitic glass shard morphologies and the sediment structures of C1 and C7 indicate that thermal granulation disintegrated the rising magma to thermally driven aqueous ash plumes that converted to eruption-fed density currents.

5x expanded by Jo-Jo Eumerus (talk). Self-nominated at 21:18, 21 February 2020 (UTC).
5x expansion and date verified. QPQ done. Interesting hook, within rules. Earwig found no copyvio. Sourcing in general appears good and hook source verified. Good to go. —David Eppstein (talk) 00:22, 1 March 2020 (UTC)
