Fig. 5From: Investigation of geomechanical properties of tephra relevant to roof loading for application in vulnerability analysesVariation of bulk density with magma composition. Values are for proximal-medial samples (< 50 km from source), distal samples (≥ 50 km from source) or the whole deposit. Dotted lines indicate a range of values was reported. Proximal-medial and distal values from the same eruption are linked by a solid green lineBack to article page
