Table with photographs of wildfire, synfire and postfire landforms. (a) First stages of the fire near Santu Lussurgiu at 6:00 pm on 24th July 2021. (b) Burnt forest few hours after the fire and evidence of spalling on building blocks made of Santa Caterina di Pittinuri marls. (c) Tephrite-phonolite boulders related to pre-fire rockfall activity with clear signs of thermal spalling. (d) Rill-interrill erosion on soils formed on Pliocene debris avalanche deposit. (e) overbank deposits made by fire ashes and organic debris close to the sea. (f) postfire debris flow deposit with clastic material showing clear evidence of thermal spalling and syn-flow fracturing.
