The Croatian Seismographic Service recorded two more earthquakes on Monday whose epicentre was 5 km southeast of Petrinja, the first at 7.49 a.m., measuring 4.7 on the Richter scale, and the second at 7.51 a.m., measuring 4.1.
The epicentre was 10 km underground, 44 km southeast of Zagreb and 11 km southwest of Sisak.
The first quake today occurred at 6.28 a.m., measuring 5 on the Richter scale.
Seismologist Kresimir Kuk said the epicentre of first tremor was in Pokupsko near Petrinja, 50 km southeast of Zagreb and 12 km southwest of Sisak.
The quake occurred at 7-8 km below ground and given the magnitude, aftershocks are possible, Kuk told Croatian Radio after the first quake.
He said damage could be expected in near the epicentre. Damage to buildings has been reported in Sisak.
Kuk warned about the danger posed by the buildings in Zagreb which were damaged in the March 22 quake.
