The Western Volcanic Zone (WVZ) is a 170-km long plate boundary that has experienced > 40 separate eruptions since the end of the last major glaciation, producing >110 km3 of subaerial lava. See map under downloads (below) |
 |
Following an initial pulse, probably related to the effects of deglaciation on mantle melting, eruption rates have steadily decreased in post-glacial time along the WVZ |
