Cars, cots and plastic chairs became temporary beds for hundreds of families who lost their homes in southwest Puerto Rico as a flurry of earthquakes struck the island, one of them the strongest in a century.

The magnitude 6.4 quake that struck before dawn on Tuesday killed one person, injured nine others and knocked out power across the U.S. territory. More than 250,000 Puerto Ricans remained without water on Wednesday and another half a million without power, which also affected telecommunications.

In addition, more than 1,000 people were staying in government shelters in the island’s southwest region as U.S. President Donald Trump declared an emergency and Puerto Rico Gov. Wanda Vázquez activated the National Guard.

The hardest hit municipality was the southwest coastal town of Guánica. More than 200 people had taken shelter in a gymnasium after a quake on Monday, only for the latest shake to damage that structure – forcing them to sleep outside.

Among them was 80-year-old Lupita Martínez, who sat in the dusty parking lot with her 96-year-old husband by her side. He was sleeping in a makeshift bed, a dark blue coat covering him.

“There’s no power. There’s no water. There is nothing. This is horrible,” Martínez said.

The couple was alone, lamenting that their caretaker had disappeared and was not answering their calls. Like many Puerto Ricans affected by the quake, they had children in the U.S. mainland who urged them to move there, at least until the earth stops shaking.

While officials said it was too early to estimate the total damage caused by the string of quakes that began the night of Dec. 28, they said hundreds of homes and businesses in the southwest region were damaged or destroyed. Just in Guánica, a town of roughly 15,000 people, nearly 150 homes were affected by the quake, along with three schools, including one three-story structure whose first two floors were completely flattened.

In Guánica itself, “We are confronting a crisis worse than Hurricane Maria,” said Mayor Santos Seda, referring to the 2017 storm that devastated the island . “I am asking for empathy from the federal government.”

He said officials believe the homes of 700 families in his municipality are close to collapsing.

Tuesday’s quake was the strongest to hit Puerto Rico since October 1918, when a magnitude 7.3 quake struck near the island’s northwest coast, unleashing a tsunami and killing 116 people.

More than 950 quakes and aftershocks have been recorded in the area of Tuesday night’s event since Dec. 31, though most were too weak to be felt, according to U.S. Geologic Survey.
