Chile was rocked by a massive 7.8 magnitude aftershock late on Wednesday, April 2. The aftershock followed the huge 8.2 quake which struck just 24 hours before, killing six people. Wednesday’s aftershock shook the west coast of the country, prompting the authorities to evacuate some areas and issue a tsunami alert. This footage from Iquique shows the impact of the aftershock and the tsunami alert sounding. Credit: YouTube/Gerardo Alejandro
