MEXICO CITY (AP) — A father holds the hand of his daughter dressed as a fairy. A 24-year-old man in a pilot uniform stares proudly at the camera. A family embraces on a soccer field.

They are among the images posted by relatives within Venezuela and abroad desperately searching for their missing loved ones following two powerful, back-to-back earthquakes on Wednesday evening.

Hundreds have been killed and thousands injured. The number of casualties is expected to climb after the 7.2- and 7.5-magnitude quakes that caused widespread damage and were among the strongest to strike Venezuela in more than a century.

With communication patchy, social media and online registries have become a crucial tool for many Venezuelans seeking information and resources beyond sparse government statistics. One independent online registry documented 51,000 people missing, while another listed 24,000 people unaccounted for, reflecting the lack of official data or information on those missing.

While some rushed to search beneath the rubble of collapsed buildings, others created digital flyers on WhatsApp, Facebook and X with their relatives’ details.

Among them was Vanesa Marcano, 31, who posted photos from Madrid of her uncle and aunt, who live in La Guaira state, north of the capital Caracas, which suffered some of the heaviest damage and casualties.

Marcano posted the images in the hopes that they were only unreachable due to damaged communication lines. Her uncle’s daughter and his 7-year-old grandson were visiting from the United States and also are missing.

“It’s a feeling of impotence and uncertainty,” Marcano said by phone. “I know you must stay calm and focus on the actions you can take. But it’s very easy to fall into despair.”

Jhoyser Concalves, a Venezuelan from the northern coastal city of Catia La Mar, was talking to his partner and her daughter just minutes before the shaking. It was the last he heard from them.

When the earthquake stopped, Concalves ran out of his house to their apartment building, where they lived on the sixth floor. There was only debris and people desperately trying to rescue neighbors from the rubble.

Concalves posted a flyer reading “MISSING” on X and Facebook in a desperate attempt to find them.

“They are pulling people out of the building alive. So I still have hope that they are in there alive,” he said.
