Great mag. 8.2 earthquake - 79km WNW of Iquique, Chile on Tuesday, 1 April 2014

Earthquake waves are fast, but still take time: This is the seismic signal showing the Chile's earthquake waves arriving at one of Etna's seismic stations approx. 7000 miles (11,000 km) away. It took the (fastest P-waves) about 30 minutes to travel almost half of the globe after the quake occurred.

The magnitude 8.2 quakes occurred off shore the Tarapace coast, about 99 km NW of the city Iquique. A tsunami alarm was issued, and the coastal areas were evacuated. Fortunately, no large tsunami was triggered by the quake (which would have had the power to generate one).
At least 5 people were reported dead and significant damage has occurred in the coastal towns, but much less than what could have been expected had the quake occurred under land or closer to the coast.

According to the German magazine
"Focus"
300 prisoners used the chaos resulting from the quake to escape.
Numerous aftershocks have been occurring including a strong magnitude 7.6 quake. Many more aftershocks will likely occur during the coming weeks and months.
