A 6.4 magnitude earthquake struck Croatia on Tuesday (December 29), killing at least one person - a child, wrecking houses, and leaving many wounded.
The epicenter was in the town of Petrinja, roughly 30 miles south of the capital Zagreb.
It came just one day after a 5.2 magnitude earthquake hit the same area.
Tuesday’s quake was felt in neighboring Bosnia and Serbia.
It even rattled the Slovenian parliament during a session.
As a precaution, Slovenia shut down its nearby nuclear power plant, according to local media.
Back in Croatia, army troops were sent into the area to help as rescuers tried to pull people from the rubble of collapsed buildings.
N1 news channel quoted a Petrinja town official as saying that a 12-year-old child had been killed, but gave no details.
In Zagreb, people rushed onto streets strewn with broken roof tiles and debris.
Patients and medical staff were evacuated from a nearby hospital.
Croatia’s Interior Minister Davor Bozinovic said the country was expecting help from the European Union as it had activated the bloc's emergency situation mechanism.
