The most powerful earthquake to hit Japan in 100 years has left a wake of destruction, and numerous people trapped and injured.
Compounding the danger, the threat of radiation exposure from damaged nuclear plants.
Ninette Sosa has some facts on surviving an earthquake's aftermath in today's Health Minute.
Time is of the essence for relief workers trying to find and treat survivors of the devastating earthquake and tsunami that struck japan last week.
"Unlike with Haiti, you saw so many people who had neither survived nor had died, but were really caught in between. Crushed by the rubble- in need of amputations, in need of acute medical care- here the situation seems to be different at least from the people that we've been talking to, the medical personnel, talking about the fact that people lived and they were going to be okay getting to these refugee camps or they died due to drowning, severe trauma due to head injury or.. just the force of the tsunami."
The Red Cross and other aid organizations are deploying numerous emergency response teams.
With frigid temperatures throughout the affected areas--those who were in the path of the tsunami could suffer from hypothermia.
"We're certainly taking supplies in to the evacuation centers. We've got things like blankets for people who had to leave everything behind."
Fresh water, food, sanitation and shelter are critical.
And if dangerous levels of radiation are released from damaged nuclear reactors... Iodine tablets will need to be distributed to those within close proximity to prevent the thyroid gland from taking on too much radioactivity.
