Which volcano is popularly known as the Lighthouse of the Mediterranean?
- A.Mount Etna
- B.Krakatoa
- C.Stromboli
- D.Mount Fuji
Correct answer
Explanation
The correct answer is C, Stromboli. Stromboli is a small island volcano in the Lipari or Aeolian group north of Sicily, and it has been in almost continuous mild eruption for centuries. The glow of its frequent bursts of incandescent material can be seen at night far out to sea, which earned it the name Lighthouse of the Mediterranean.
Option A, Mount Etna, also in Italy on the island of Sicily, is the tallest active volcano in Europe and erupts often, but the lighthouse epithet belongs to Stromboli. Option B, Krakatoa, lies in the Sunda Strait of Indonesia between Java and Sumatra, far from the Mediterranean, and is remembered for its catastrophic eruption of 1883. Option D, Mount Fuji or Fujiyama, is the composite cone of Japan and the standard textbook example of that type. This nickname is a favourite one-line question, so tie it to Stromboli alone.
