A 5.1 magnitude earthquake struck the northern region of Italy at a depth of 10.2 km or 6.3 miles below the surface. The epicenter of the earthquake was about 13 km from Parma, Italy and about 368 km from Rome. The earthquake was preceded by a much shallower 4.0 foreshock some 47 km away. Italy has seen a growing amount of seismic unrest along the northern mountainous region of the country. The Alpide Belt which runs along the southern region of Europe and Asia continues to show signs of stress. In the meantime, we continue to monitor the stresses erupting along the planet's lower southern hemisphere. A 5.1 magnitude earthquake was reported west of New Zealand's South Island.
