Legnica - A moderate earthquake struck northwest of the Polish city of Legnica on Saturday morning, seismologists said. There were no immediate reports of damage or casualties.

The earthquake, which had a preliminary magnitude of 4.9, struck about 27 kilometers (16.7 miles) northwest of Legnica at a depth of 2 kilometers (1.2 miles), according to the European-Mediterranean Seismological Centre. It happened at 05.55 a.m. local time.

Earthquakes of such magnitudes are rare in Central Europe, and a seismologist at the United States Geological Survey (USGS) called it a "significant event" for the region. The strongest earthquake ever recorded in Poland since 1973 was a 5.4 on December 31, 1999.

There were no immediate reports of damage or casualties from the earthquake.
