The Tiran cluster is named for the Strait of Tiran and Tiran Island at
the northwestern end of the Red Sea. It includes earthquakes from the
northern Red Sea and the southern portions of the Gulf of Aqaba and the
Gulf of Suez. Local station coverage was poor until about 2004 but is
quite good since then. To achieve adequate location calibration it was
necessary to retain many small events that were observed only to
near-regional distances, but the cluster contains 19 earthquakes, up to
magnitude 5.1, that were recorded teleseismically. Unfortunately it was
not possible to include the Ms 6.6 earthquake of March 31, 1969 due to
insufficient connectivity with the modern events.
