Each morning that Venezuelans wake to the aftermath of the dual earthquakes, it is a little darker, a little grimmer.

It means another night in which prayers for the miraculous recovery of missing loved ones went unanswered, in which the fitful sleep of the survivors is interrupted by nightmares of collapsed buildings and moments of sheer panic.

For ex-policeman Jan Carlos Roa Garcia and his family, it was another night sleeping rough. Their building in Caracas wasn't brought down but is too dangerous to return to.

Tears rolling down his cheeks, he says he's not sure he even knows how to rebuild his family's life again.

"If I was 30 and not 50, then maybe. But I don't know where to begin. And so far, no-one in authority has contacted us."

As a loyal public servant, Jan Carlos was careful not to over-criticise the government's response, exhausted and angry though he is.

Musician Zaira Castro had no such reservations.

"We're all pretty frustrated because the government is not showing what it should – a serious display of help," she says in a plaza just a block away from two collapsed buildings.

"It's actually us, the Venezuelans, who are helping each other. We live in a society that has grown into helping each other. We don't depend on the government – that doesn't exist for us anymore."

In the same part of town, called Chacao, the Interim President, Delcy Rodriguez, took a tour with the mayor and was on the receiving end of residents' ire.

"You're campaigning in the middle of a tragedy! The government isn't doing anything for the people," yelled one resident.

At the scene of the worst-hit areas – particularly the coastal town of La Guaira – the desperation is even greater. The scene around more than 100 flattened buildings is apocalyptic. And as hopes fade, anger grows.

"There are still people in there, we need machinery," says affected resident Eileen Lada. "Help us, please," she pleads.
