Quito, Ecuador: The death toll from the powerful earthquake that struck Ecuador over the weekend has risen to at least 413, government officials reported on Monday.

‘We are counting 413 people dead at present,’ the country’s security ministry said. The new toll from the 7.8-magnitude earthquake that hit Ecuador on Saturday evening updates an earlier count of 350.

At that time authorities said more than 2,000 people were injured.

Foreign countries and organizations dispatched rescue teams to help the search and medical units to treat the thousands of people injured, saying tens of thousands would need aid.

Rebuilding the destroyed areas will probably cost billions of dollars, President Rafael Correa said during a visit to Pedernales.

Along the Pacific coast, in the towns of Pedernales, Manta and Portoviejo, the stench of rotting bodies filled the tropical air among heaps of rubble and twisted metal. Rescuers with sniffer dogs roamed the wreckage.

Rising death toll

Correa said on Sunday that the death toll would ‘certainly rise and probably in a considerable way’ in the hours ahead.

‘There are still lots of bodies in the rubble,’ he warned. ‘These are extremely difficult times, the biggest tragedy in the last 67 years.’

He was referring to an August 1949 earthquake near the central Ecuadoran city of Ambato that killed some 5,000 people.

In Pedernales, Mayor Gabriel Alcivar estimated there were hundreds of dead buried under the rubble of collapsed hotels.

Soldiers patrolled the beach town, and the Red Cross and the army opened a field hospital and a makeshift morgue at the local stadium.

‘Here in Pedernales survivors have been rescued among the rubble and we are not losing hope that more will be found,’ Ecuador’s Vice President Jorge Glas, who visited the town, told AFP.

Aid flows in

Foreigners killed by the quake include two Canadians, five Colombians and at least one US national, officials said.

A Catholic missionary nun from Northern Ireland was killed along with three trainee nuns at a school, her religious congregation said.

Although Ecuador frequently suffers seismic shudders because of its position on the Pacific Rim’s ‘Ring of Fire,’ the weekend’s quake—which lasted a full minute—was the worst in nearly 40 years.

Since 1900 Ecuador has been rocked by seven earthquakes of magnitude 7.0 or higher in the region of Saturday’s quake, the US Geological Survey said. One in March 1987 killed about 1,000 people.

International sympathy and offers of help flowed in.

The United Nations refugee agency UNHCR said it was preparing to airlift supplies including hundreds of tents and kitchen sets as well as mosquito nets to protect people from the Zika virus.

It said it aimed to provide shelter and aid to 40,000 people, including Colombian refugees settled in the area.

The Spanish Red Cross estimated that up to 100,000 people would need assistance.

The World Bank said it had a credit line of $150 million ready to help with reconstruction. Correa’s government said it had access to $600 million in emergency credit overall.

But Correa said that rebuilding the various ruined towns ‘will take months and years and will cost hundreds of millions, and probably billions, of dollars.’
