WASHINGTON (AP) -- The State Department is urging Americans to avoid nonessential travel to Chile.
U.S. citizens in Chile are being asked to contact family and friends in the United States by phone, Internet or cell-phone text messaging.
Those without such access are encouraged to register with the nearest U.S. Embassy or Consulate.
Looting is so bad in the earthquake ravaged Chilean city of Concepcion that the government has sent soldiers to the city and ordered a nighttime curfew.
President Michele Bachelet says Chile is facing "a catastrophe of such unthinkable magnitude that it will require a giant effort" to recover from big quake.
