An earthquake measuring 6.4 on the Richter Scale struck the near the town of Petrinja in Croatia on Tuesday at 1130 GMT. At least one child, a 12-year-old girl, is reported to have been killed. Petrinja is home to 20,000 people and rescue operations are still on.

Shockwaves were reportedly felt even in the capital city of Zagreb that lies 30 miles North of the epicenter. Prime Minister Andrej Plenkovic rushed to Petrinja and tweeted, “We mobilized all available services to help people and clear the destroyed parts. The most important thing now is to save human lives.”

He also tweeted pictures of the relief efforts amidst the destruction.

This earthquake comes just a day after a series of tremors were felt in the region, their epicenter located a few miles South of Sisak. Ursula von der Leyen, President of the European Union Commission, who had been monitoring the situation via contact with Prime Minister Plenkovic since the first set of tremors yesterday, also pledged support to the people of Croatia.

Croatia lies in the seismically active Balkan region and Zagreb experienced three powerful earthquakes on March 22. Balkan Insight reported that the intensity toppled one of the two spires of the capital’s cathedral.
