Which risk rises significantly when valley-confined lava flows develop levees?

💡 Explanation

Flow diversions increase downstream because the mechanism, thermal insulation, decreases lateral heat loss in the channel. Therefore, flow builds elevation, and levees form, rather than spreading. Heat is retained, enabling more sudden channel breakthrough.
