SANTIAGO, Chile (AP) -- Authorities have lifted tsunami warnings for Chile's long coastline after a magnitude-8.2 earthquake struck the country's northern coast.
Six people were crushed to death or suffered fatal heart attacks.
President Michelle Bachelet says the extent of damage from Tuesday night's quake is still being assessed. She's declared a state of emergency in the region and has sent a military plane with 100 anti-riot police to join 300 soldiers deployed to prevent looting and round up 300 inmates who escaped from a women's prison.
The powerful quake and more than 20 significant aftershocks touched off landslides that blocked roads, knocked out power for thousands, damaged an airport and provoked fires that destroyed several businesses.
Near the quake's offshore epicenter, authorities say hospitals treated minor injuries and some homes made of adobe were destroyed.
