The situation has grown more desperate by the hour in Venezuela

knowing time is running out to find survivors.

The death toll from the two quakes stands at more than 920

with at least 51,000 missing.

government rescuers to help them.

Omar Guariato, a displaced resident said

"There was no time for anything, and even though we tried to leave...

my house didn't collapse, but then when my daughter went out to look

for her child, the house next door, which is three stories,

collapsed and fell on top of her. It covered her, she was trapped.

Aid agencies consider the first 48 to 72 hours to be a crucial time frame

to retrieve people alive though that period can be extended if they

have access to food and water.

Rescue teams from Mexico and other nations began to arrive

in Venezuela Friday to help with search efforts.

Among those international aid contingents were Topos Aztecas

renowned search-and-rescue specialists.

The team has been deployed alongside Mexican Army K-9 units

and medical teams.

This rescue team member said, "The idea is to assess the structures

and deploy the dogs to guide us to where we need to work.

Naturally we are searching for survivors, which is our top priority right now."

Speaking on state TV, Venezuelan authorities announced access would

be restricted to the hard-hit La Guaira region.

The country's interior minister said acting president Delcy Rodriguez had

ordered access restricted to the region to allow first responders to travel

in and out of the state.

Meanwhile in Doral, South Florida residents brought supplies to a collection

site on Friday to be sent to the victims of the deadly earthquakes.

Dozens of volunteers manned the site, sorting donations into boxes

which included items such as non-perishable food, water, medicine and

clothes ready to be shipped to the South American nation.
