Ecuador earthquake destruction could force relocation of towns, UNICEF says

The devastation from Saturday's earthquake in Ecuador, with a death toll of 587 so far,is so great that some communities will likely need to "start from new," theUNICEFrepresentative in that country says.

"There are one or two locations where the government's contemplating relocating towns ... because of the level of destruction," Grant Leaitytold CBC News on Wednesday evening.

• 4 Canadians confirmed dead in Ecuador earthquake

Several days after the disaster, people desperately continue to dig through rubble in the hopes of finding survivors, as aid workers try to assess the enormous humanitarian consequences of the largest quake Ecuador had seen in decades.

"We're still going strong, and everybody is, in terms of search and rescue," Nicolas Verdy of the Canadian Red Cross told CBC News on Wednesday. "We have full teams going through the rubble, being helped by the military, by the government."

"Obviously time is running out so they're moving as quick as they can," he said.

Verdy, who lives in Ottawa,manages international emergency operations for the Canadian Red Crossand has been travelling to hard-hit areas on Ecuador's Pacific coast since he arrived on Monday.

But it's hard to get "a full picture or a clear picture of the needs," he said, as blocked roads are impeding access to some communities.

UN appeal expected

Even a partially-completed picture, however, shows that the humanitarian response required is enormous. In addition to homes, critical infrastructure like hospitals and schools were damaged, or in some cases, completely destroyed.

The United Nations is expected soon to announce a global appeal for around $70 million US ($88 million Cdn) to fund relief efforts in Ecuador over the next three months, Leaity told CBC News.

• Billions needed to rebuild, Ecuador's president says

Hundreds of Ecuadorian Red Cross volunteers mobilized in the first 24 hours following the earthquake, Verdysaid.

In addition to search and rescue efforts, the agency isfocused on providing first aid and medical treatment to the thousands of people injured, he said, as well as "psychosocial support."

"There's a lot of people that are traumatized," Verdysaid."People are sleeping outside. People are scared. There's a lot of aftershocks."

Both the Red Cross and UNICEF are also providing shelter and clean water, deploying supplies that were already pre-positioned in the region, with more coming from international warehouses.

Zika, dengue among illness concerns

Other critical items, they say, are mosquito nets to protect people while they're sleeping outside or in shelters particularlyas Ecuador battles Zika virus.

It's "a major concern," Leaity said, noting that the same mosquito that carries Zika virus also causes dengue fever.

After the initial life-saving needs are met, UNICEF and other agencies will try to restore as much normalcy as possible for children, partly by working with the Ecuadorian government to get them back to school within weeks or months,Leaity said.

But rebuilding in Ecuador will be a long process, both aid agencies say.

"We're going to see people in need not just for the next coming weeks but the next coming months," Verdy said."For some people, it's going to be for the next coming years."

'Wake-up call' for construction standards

The earthquake's epicentre "was very close to the poorer parts of the coast," Leaity said.

That contributed to the severity of the destruction in some areas, aid agencies say.

"The poorer people have less solid houses so their houses tend to get destroyed first,"Verdysaid.

A lot of the houses were "built on very poor ground soil quality," Leaity said, adding that "this earthquake is a wake-up call" for construction standards.

Both agencies say it's essential to adopt the principle of "build back better" in helping Ecuador rebuild.

If people's homes are built to appropriate standards,"the next time there's an earthquake they might not lose everything," Verdysaid. "It might save their lives."
