Pisco is a town that has been devastated and thousands of its residents are waiting for aid, for food, for basic services to be restored.
People in Pisco need urgent help amid the ruins of their town
There is no electricity, no fresh water, not enough supplies and people are exposed to the bitter winter cold.
Some aid is starting to get through from the capital, Lima, but deliveries have been badly held up because the roads to Pisco are so badly damaged.
Pisco is a town on the coast, in a desert region where heat during the day is unbearable and where at night the temperatures fall dramatically.
Only those who have managed to get hold of a blanket have any protection from the cold.
People have taken wood from the destroyed houses to use for fires, and on every street corner there is a fire with people huddled around it, waiting for someone, anyone, any official to come to help them.
It really is a desperate situation.
In Pisco, Ica and other affected areas, the authorities are trying to register those who have lost their homes so the government can get an idea of the scale of the damage.

The director of the civil defence told me they had been overwhelmed by the disaster and that no country could have been prepared for an event on this scale.
We still don't have a clear idea of the situation in the more remote villages and hamlets.
Civil defence officials have started to get news from these areas, and the indications are that many homes, which are often built from flimsy materials, have collapsed. It is clear that these remote areas need urgent help.
But if aid is only now getting through to Pisco, people affected by the earthquake in more remote areas are clearly going to have to wait even longer for help to arrive.
