A very strong earthquake registered by the USGS as M6.7 hit near Coquimbo, Chile at 01:32 UTC on Jan 20 (22:32 local time, Jan 19). The agency is reporting a depth of 53 km (33 miles).
Two residents of Coquimbo suffered cardiac arrests as a result of the quake, local police have said, adding that the death toll is likely to grow.
The epicentre was located 15 km (9.3 miles) SSW of Coquimbo (population 161,317), and 25 km (15.5 miles) SW of La Serena (population 154,521), Chile.
At the time of writing, four aftershocks have been registered ranging from M4.0 to M4.5.
430,000 people are estimated to have felt very strong shaking, 96,000 strong, 105,000 moderate and 2,760,000 light — the USGS issued a yellow alert for shaking-related fatalities and economic losses.
Immense damage was reported across the region, including landslides on national highways and a huge boulder destroying a house in Andacollo.
Residents of Coquimbo and La Serena fled to high ground following the quake, but returned back after authorities ruled out a tsunami.
The Coquimbo region experienced a devastating tsunami in September 2015 after an M8.3 earthquake struck, killing a dozen people.
Chile is one of the world’s most earthquake-prone countries — the 1960 Valdivia earthquake was the strongest ever recorded, at magnitude 9.5, according to the USGS.
Seismic and Volcanic activity has been correlated to changes in our sun.
The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, and the increase in Galactic Cosmic Rays penetrating silica-rich magma.
