With the window for finding survivors shrinking fast, Venezuelans combed through more ruins of buildings toppled by last week’s devastating back-to-back earthquakes. Attention also turned to the country’s humanitarian crisis that could persist for years. Relief organizations say the first 72 hours after a natural disaster is the most crucial time period for rescues, though survival can be extended if people have access to food and water. Five days after the twin quakes, questions loomed about whether the cash-strapped government will be able to coordinate the effort needed to care for thousands of people who have been left homeless. The death toll stood at more than 1,700 people.

NEW YORK (AP) — For those trapped in rubble after an earthquake, survival depends on many factors, including weather and access to water and air.

Tensions are high in Venezuela as the death toll rises to 1,430 after two powerful earthquakes struck three days ago. Families have reported that 68,900 people are missing. Many civilians are leading search efforts, frustrated by what they see as an inadequate government response. International rescue teams continue to join the effort, with 17 flights bringing over 1,600 rescue workers by Saturday. The disaster is a major challenge for acting President Delcy Rodríguez. The capital's main airport is damaged, complicating aid delivery.
