Jabuka (island)

Jabuka has tall cliffs. The island is composed of igneous magnetite rocks, which cause magnetic anomalies that confuse compasses. Due to its iron-rich rock, Jabuka is frequently struck by lightning. Another series occurred in 2004–05 with a 5.2 quake. However, due to Jabuka's remoteness, these earthquakes are weakly felt on the Croatian mainland and inhabited islands. ==Flora and fauna==

Its coast is steep and difficult to approach, and landings can be made only when the weather is clear. The easiest access is on the southwest side. On the island, noteworthy species such as a Dalmatian Wall Lizard and some plants (Centaurea jabukensis and Centaurea crithmifolia, both Asteraceae) are protected endemics. In 1958, the island was declared a geological monument of nature. The surrounding sea is rich with fish, especially sea bream. However, due to remoteness, lack of safe harbour, strong currents, and sudden changes of weather, fishermen have traditionally avoided the waters around Jabuka. Birds Jabuka, along with Vis, Sveti Andrija and its neighbouring islet of Kamnik, Brusnik, Biševo and the Palagruža archipelago, forms part of the Croatian Offshore Islands Important Bird Area (IBA). This was designated as such by BirdLife International because it supports significant breeding populations of Scopoli's and Yelkouan shearwaters, as well as of Eleonora's falcons. == References ==
