Original Note:
Lava expelled from a volcano cannot melt concrete. Concrete melting point: 1550C Lava max temperature at eruption: 1200C The idea of plugging a volcano with concrete is dangerous for a different reason. The concrete plug will cause pressure build up resulting in a explosion www.structuralguide.com/concrete-melting-point/ en.m.wikipedia.org/wiki/Lava
