MADRID, Aug. 18 (Xinhua) -- Three people sustained minor injuries on Tuesday as a series of earthquakes struck Spain's southern province of Granada, the latest seismic activity to hit the area following a magnitude-5.0 earthquake early Saturday, according to the Andalusian regional government.

One of the injured, a minor, was taken to hospital. The tremors also caused cracks and falling debris and prompted precautionary evacuations from several buildings.

The strongest earthquake, measuring magnitude 4.8, struck at 10:37 a.m. local time (0837 GMT), according to Spain's National Geographic Institute (IGN). Its epicenter was located northwest of the municipality of Gojar, near the city of Granada.

It was followed by several tremors, including earthquakes of magnitude 4.2 and 3.9, IGN data showed.

The latest seismic activity came three days after a magnitude-5.0 earthquake struck Granada and surrounding areas early Saturday, damaging buildings and vehicles but causing no injuries.

Juanma Moreno, president of the Andalusian regional government, urged residents to exercise "maximum caution," warning that further seismic activity and aftershocks could occur.

Antonio Sanz, the regional minister responsible for emergency services, said authorities would convene the advisory committee under Andalusia's seismic-risk emergency plan to assess the situation. The plan has remained active since Saturday's earthquake.

Southern and southeastern Spain are among the country's most seismically active areas due to the convergence of the African and Eurasian tectonic plates.
