A SMALL earthquake hit Melbourne's outer eastern suburbs today, but caused no damage.

Registering 1.8 on the Richter scale, the quake struck Narre Warren at 12.29pm, the Herald Sun reports.

Geoscience Australia seismologist Dr Jonathan Bathgate said they received about 20 inquiries about the tremor.

There was an even smaller aftershock in the same location about 10 minutes after the initial quake.

“It is always difficult to tell what we are going to get. We can’t rule out another earthquake in coming days,” Dr Bathgate said.

This is not the first time the area has experienced an earthquake. Tremors measuring under 3 were recorded in Berwick in 1973, Officer in 1990 and Pakenham in 1997.
