The ongoing earthquake sequence along the south coast of Puerto Rico continues today with a M6.6 earthquake just now. Yesterday's M5.8 earthquake (now can be called a "foreshock") caused some damage to buildings, so further damage can be expected with today's quake.

Una de las casas en la urbanización que estoy se derrumbó. Yauco. Pilló al carro y todo lo que estaba debajo. Sus residentes están bien.

Wonder what Dutchsinse will have to say about this when he wakes up?
He'll probably give us a pretty good idea as to what to expect next.
Stay tuned!​

The Ricans are going to have a real water problem on their hands. Cisterns are draining as I write this. Down there they build out on hillsides. One portion is anchored to the hill, the opposite is supported on concrete stilts. Most cases the cisterns are part of the anchoring foundation to the hillside. Many are poured, some cheaper are constructed of block. Cisterns not integral of the house are usually stand alone plastic tanks.
Cheaper concrete homes with little rebar are probably the hardest hit. Water is precious down there. Most of it is collected off roof tops and directed into the holding tanks. But wells do exist in some of the valleys. That would be where the water trucking companies draw water for customers that run low during drought and need buy water. You don't buy water for a leaking cistern. It would be an expensive waste. I bet the plastic ones will sell out. The worst is a slow leaking cistern. Hard to detect. It's a slime job to crawl inside one to work.

PR can’t catch a break. Hurricanes, earthquakes and corrupt government only interested in lining their own pockets is not a recipe for succes.

Neither here nor there.
Puerto Rico sits smack dab on the Puerto Rico Trench, it's a massive fault/trench that runs east to west from the Mariana Trench in the Atlantic to some other north to south fault line to the west. It sits on what is considered the ring of fire. An 8.5+ is not out of the question for PR.

I think you're in the wrong ocean. The Mariana Trench is south (more-or-less) of Japan and it's the Pacific Rim that's called the "Ring of Fire." There is a subduction zone in the Caribbean, but as far as I know it's fairly far south of Puerto Rico.

The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean. The oceanic trench is associated with a complex transition between the Lesser Antilles subduction zone to the south and the major transform fault zone or plate boundary, which extends west between Cuba and Hispaniola through the Cayman Trough to the coast of Central America.

The trench is 800 kilometres (497 mi) long and has a maximum depth of 8,376 metres (27,480 ft) or 5.20 miles in the Brownson Deep, which is the deepest point in the Atlantic Ocean and the deepest point not in the Pacific Ocean. On December 19, 2018, its deepest point was identified by the DSSV Pressure Drop using a state-of-the-art Kongsberg EM124 multibeam sonar and then directly visited and its depth verified by the manned submersible Deep-Submergence Vehicle DSV Limiting Factor (a Triton 36000/2 model submersible).[1][2][3]

Scientific studies have concluded that an earthquake occurring along this fault zone could generate a significant tsunami.[4] The island of Puerto Rico, which lies immediately to the south of the fault zone and the trench, suffered a destructive tsunami soon after the 1918 San Fermín earthquake.

I wasn't disputing the Puerto Rico Trench. I was noting that your reference to the Mariana Trench and the Ring of Fire were not in the Caribbean or the Atlantic.

Haiti's 2010 earthquake that killed anywhere from 100,000-300,000 (depending on the source) was "only" a 7.0. Haiti had an estimated 8.0 earthquake in 1751. There was an estimated 8.3 in the Lesser Antilles in 1843. So clearly the Caribbean is no stranger to very large and very destructive earthquake events (including devastating tsunamis). So your overall point was totally valid, even if you did misplace the Mariana Trench by about 8,000 miles. :)

SAN JUAN, Puerto Rico (AP) — A magnitude 5.9 quake shook Puerto Rico on Saturday, causing further damage along the island’s southern coast, where previous recent quakes have toppled homes and schools.

The U.S. Geological Survey said the 8:54 a.m. (1254 GMT) quake hit 8 miles (13 kilometers) southeast of Guanica at a shallow depth of 3 miles (5 kilometers).

Puerto Rico’s Electric Power Authority said outages were reported across much of southern Puerto Rico and crews were assessing possible damage at power plants.

Bárbara Cruz, a prosecutor who was in the southern coastal city of Ponce when the new quake hit, said concrete debris hit the sidewalk as buildings continued to crumble.

“Everyone is out on the street,” she said.
There were no immediate reports of injuries.

The quake, which initially had been calculated at magnitude 6.0, was the strongest shake yet since a magnitude 6.4 quake — the strongest to hit the island in a century — struck before dawn on Tuesday, knocking out power across Puerto Rico and leaving many without water. More than 2,000 people remain in shelters, many fearful of returning to their homes, and others unable to because of extensive damage.

Hundreds of quakes have shaken the island since the new year, though most were too slight to be felt.
NASA reported Friday that the quakes had moved the land in parts of southern Puerto Rico as much as 5.5 inches (14 centimeters), based on satellite images before and after the temblors.

Víctor Huérfano, director of Puerto Rico’s Seismic Network, told The Associated Press that he expects still more aftershocks as a result of the latest large one.

“It’s going to re-energize an unstable situation,” he said, adding that seismologists are studying which faults were activated. “It’s a complex zone.”

Hundreds of thousands of Puerto Ricans are still without power and water, and thousands are staying in shelters and sleeping on sidewalks since Tuesday’s earthquake. That temblor killed one person, injured nine others and damaged or destroyed hundreds of homes and several schools and businesses in the island’s southwest region.

I haven't seen it in stories posted here, but as I understand many (if not most) of the power outages result from shutting down various parts of the infrastructure to assess damage and not from damage caused by the earthquakes themselves. Why it would take them so long to assess damage and get the power back on is, I guess, another story.
