Mini-tsunamis in Mallorca: Harmless natural phenomenon — or an underestimated danger?

Answer

What are rissagas and why do they happen around Mallorca?

Rissagas are rapid changes in sea level caused by a combination of air pressure shifts and harbor geometry. In Mallorca they tend to be small, but certain bays with specific orientations can show stronger fluctuations. The phenomenon is well explained by meteorology, with local variability on the island.
