The earthquake, which registered a 3.3 on the Richter scale, hit the northwestern area of the body of water at 8:50 a.m., Haaretz reported.
On Sunday, two earthquakes, with magnitudes of 3.6, hit the same area.
On Saturday, a 3.6-magnitude quake hit, and last week, a 3.5-magnitude earthquake was recorded in the same region.
No damage has been reported.
"There were similar cases in the past in which a number of earthquakes clustered around the same time and place, among other cases in Lebanon and the Gilboa [in northern Israel]," Dr. Uri Friedlander, the head of the Israel Geophysical Institute, said. "The truth is we don't know what this recent string means."
The sea is located on a seismically active rift, which has seen devastating earthquakes with magnitudes of 6 and higher, Haaretz said.
