Red Alert on Ibiza: What the Island Must Learn Now

Answer

Why do Mediterranean islands like Mallorca and Ibiza flood so quickly after heavy rain?

Flooding can happen fast when rain falls on built-up areas with lots of concrete, sealed ground and limited space for water to drain away. Outdated drainage systems and missing retention areas can make the problem worse. When that happens, even a short storm can lead to major disruption.
