SAN CRISTOBAL CUCHO, Guatemala — The 10 members of the Vasquez family were found together under the rubble of the rock quarry that had been their livelihood, some in a desperate final embrace, others clinging to the faintest of dying pulses.
As Guatemalans sought Thursday to pick up the pieces after a 7.4-magnitude quake, one family’s tragic story came to symbolize the horror of a disaster that killed at least 52 people and left thousands of others huddling in the cold shadows of cracked adobe buildings, most without electricity or water.
On Thursday, neighbors came to pay their respects. They filed past 10 wooden caskets in the Vasquez family living room, and contemplated the unspeakable future that awaits the family’s only surviving son. Justo Vasquez, his wife Ofelia Gomez, six children, and two nephews died in the rubble.
Only the eldest son, Ivan, 19, survived. He had stayed in the house when the rest of his family went to the quarry, taking care of some last-minute details to receive his accounting degree — the first in his family to have a professional career.
His father had been saving for a party to celebrate his Nov. 23 graduation.
‘‘He died working,’’ said Antonia Lopez, a sister-in-law of Justo Vasquez. ‘‘He was fighting for his kids.’’
Hundreds of villagers in the humble town of San Cristobal Cucho ran to dig the family out on Wednesday after Guatemala’s biggest quake in 36 years.
When they uncovered some of the children, one body still warm, two with pulses, they were in the arms of their father, who had tried to shield them from a falling mountain.
The death toll was expected to rise as 22 people remained missing, President Otto Perez Molina said at a press conference.
Eight were killed in the neighboring state of Quetzaltenango.
Perez said a powerful 7.4-magnitude quake, felt even in Mexico City 600 miles away, affected as many as 1.2 million Guatemalans. A little more than 700 people were in shelters, with most opting to stay with family or friends, he said.
‘‘They have no drinking water, no electricity, no communication, and are in danger of experiencing more aftershocks,’’ Perez said. The president said there had been 70 aftershocks in the first 24 hours after the quake, some as strong as magnitude 5.1.
Damaged homes are among the biggest problems the country will face in the coming days, Perez said.
The Vasquezes were the only ones to die in San Cristobal Cucho, a mountain village of cobblestone streets, where buildings suffered some cracks and damage and early reports said the family had perished in a collapsed house.
Like the rest of several thousand people in town, the Vasquez family was humble, the parents without much education. Most of the people in the town are subsistence farmers or sell things on the streets and in the markets.
‘‘We have never seen a tragedy like this. The whole town is sad,’’ said Justo’s brother Romulo Vasquez, whose 12-year old son, Ulises, also died at the quarry.
Justo Vasquez and his wife left for work at 5 a.m. Wednesday to the land they rented to quarry white rock, which is pulverized to make cinder blocks. They returned later in the morning to eat breakfast, then took six of their seven children and two nephews back to the quarry with them, because the children were on vacation from school.
The oldest child to die was Daisy Vasquez, 14, the youngest Dibel Vasquez, 3.
The eldest son, Ivan, was too distraught to speak or even stay at the red-and-yellow block house where hundreds of people gathered, passed by the caskets, or waited outside the door marked by candles and just a few flowers. Wood smoke bathed the memorial as more than a dozen women in the back of the house cooked rice, beans, corn, and eggs to feed the crowd.
‘‘He was a very good father, he was a very good neighbor,’’ said Antonia Lopez, who was among the many paying respects.
Guatemalans fearing aftershocks huddled in the streets of the nearby city San Marcos, the most affected area, where at least 40 people died. Others crowded inside its hospital, the only building in town left with electricity.
More than 90 rescue workers continued to dig with backhoes at a half-ton mound of sand at a second quarry that buried seven people.
‘‘We started rescue work very early,’’ said Julio Cesar Fuentes of the municipal fire department. ‘‘The objective is our hope to find people who were buried.’’
But they uncovered only more dead.
