A powerful 7.1‑magnitude earthquake swayed buildings and cracked streets and foundations in Southern California, USA on Friday night sending terrified residents into the streets a day after another quake hit.
According to the US Geological Survey, it was five times bigger and 11 times stronger than Thursday's 6.4 ‑magnitude earthquake.
The region has seen an average of one aftershock per minute since Friday's quake in the southern part of the state.
