Mr. Cuomo’s criticism of the federal government’s response to the earthquakes focused on the fact that Mr. Trump still has not released hurricane-related federal funds that he said could be used to address damage from the earthquakes. The seismic activity began in late December and have forced thousands of fearful residents from their homes: More than 8,000 residents are scattered in more than 40 shelters, and thousands more are sleeping in makeshift tents and inside parked cars near highways.

But the island is clearly showing signs of recovery: Electricity has been restored to 99 percent of customers, and the Army Corps of Engineers has mobilized personnel to help install generators.

Mr. Cuomo, along with a delegation of elected officials from New York, toured a major natural gas power plant that was damaged in the southern part of the island. It used to produce about a quarter of the island’s electricity, but officials expect it will now be shut down for several months.

Mr. Cuomo also visited Guánica, a coastal town that received the brunt of the damage from the earthquakes. He walked its narrow streets with the town’s mayor, observing homes — most of them built on stilts — that had collapsed.

Santos Seda, the mayor, said that 700 of the town’s 8,000 homes sustained damage and that there was a lack of engineers to inspect the structures.
