Is flooding and the destruction of a bridge likely to occur in the aftermath of a volcanic eruption in the cascades range? explain.

Thick stacks of lava flows (30 m or 100 ft thick) can take years to cool completely. It also depends on the range between the volcano and bridge, the cascades range has a lot ( a LOT ) of volcanoes so most likely
