A magnitude 6.4 quake shook people awake at 4:24 a.m. local time Jan. 7, less than 24 hours after a magnitude 5.8 temblor shook the island in the predawn hours of Jan. 6.
Aftershocks ranging in magnitude from 3.8 to 6 were felt throughout the island following the early morning temblor, reported the U.S. Geological Survey.
The continuous shaking has taken a psychological toll, said Father Enrique Camacho, executive director of Caritas of Puerto Rico, which is affiliated with Catholic Charities USA.
"Right now we are helping the people with emotional support," Father Camacho told Catholic News Service Jan. 7. "What we fear is that we continue having these earthquakes. If we have bigger ones, the damage is going to be very, very, very bad."
Archbishop Jose H. Gomez of Los Angeles, president of the U.S. Conference of Catholic Bishops, offered "prayerful solidarity" to the people of Puerto Rico in a Jan. 7 statement.
"The church in the United States stands with you," he said. "In our prayer, we recall in trust that Jesus is the resurrection and the life, offering himself to us and calling us to himself even in our darkest hour."
Meanwhile, charitable and aid agencies have begun collecting funds to assist in the emergency response and recovery.
Catholic Charities USA established a donation page on its website, catholiccharitiesusa.org.
In addition, Catholic Extension is seeking donations to help with pastoral needs at its website, catholicextension.org/relief.
"We stand in solidarity once again on the front lines offering our support and comfort to those enduring the terror and destruction of these earthquakes," Father Jack Wall, the agency's president, said in a statement.
The latest earthquake sent people scurrying from their homes into the streets from Ponce, the island's second-largest city, westward along the island's southern coast to the towns of Guayanilla, Guanica, Yauco and Lajas, all near the epicenter of the quakes.
Police in Ponce said a 73-year-old man died when a wall fell on him, reported El Nuevo Dia, Puerto Rico's largest newspaper.
Immaculate Conception Church in Guayanilla was severely damaged, Mayor Nelson Torres Yordan told a local television station. Photos posted by El Nuevo Dia showed residents removing the church's undamaged tabernacle to safety.
Father Camacho said the church had survived the island's major earthquake of 1918, only to be shaken apart by the Jan. 7 temblor. "The only church that remained on the street (in 1918) was that," he said. "Then 100 years later, with this earthquake, it is the one that fell down.
"That's really sad because it was a very historical monument, a tourist place," he added.
Father Camacho said he had been in contact with Bishop Ruben Gonzalez Medina of Ponce, where the cathedral experienced some damage. Mass was canceled Jan. 7 at the cathedral and numerous parishes across the diocese, he said.
"I talked with a priest in charge of social ministry in Ponce," Father Camacho told CNS. "He told me even himself he is not traveling to see what is happening (in the diocese) because they are afraid there could be more ruts in the road and their lives are in danger.
Puerto Rico has experienced a series of minor earthquakes beginning the night of Dec. 28-29 leading to the major shakers, reported the U.S. Geological Survey.
The most recent large quake knocked out power to much of the island, including the capital of San Juan. The Puerto Rico Electric Power Authority reported that all of its power plants went offline after its "auto protection" systems were activated.
The company reported damaged to one of its main power plants near the earthquake's epicenter, but that technicians were working to restore electricity to other parts of the island.
Archbishop Robert Gonzalez Nieves of San Juan tweeted soon after the quake Jan. 7: "A 6.7-point earthquake has just shaken all of Puerto Rico that is now without light. Prayer, serenity, solidarity and charity are important. We are one family!"
In his statement, Archbishop Gomez offered prayers for Archbishop Gonzalez and all people who serve local faith communities.
He also noted that Puerto Rico continues to recover from extensive damage caused by two hurricanes in September 2017. "In this moment of continued trial, may you know of God's consolation and strength to confront this trial, through the loving intercession of his mother and ours, Our Lady of Divine Providence, patroness of Puerto Rico," he said.
Father Camacho said if more powerful earthquakes occur, he feared damage in the rural mountainous center of the island, where housing is less sturdy, would be severe.
As for an immediate response, Caritas of Puerto Rico is in a holding pattern.
"We are waiting to see what are the damages," the priest said. "We are willing to help people reconstruct as soon as possible."
