SAN JUAN, Puerto Rico — After a 6.4 magnitude earthquake rattled Puerto Ricans before dawn on Tuesday, the island found itself in total darkness. The massive quake and its hundreds of aftershocks took down the electrical grid with it, leaving millions without power, one dead, and dozens of homes and businesses in the southern coast in shambles.

The 6.4 quake is the most powerful occur since seismic activity began to shake the island on December 28.

When the dust settled and the sun finally rose, Puerto Ricans in the south found extensive damage to homes, schools, churches, and historical landmarks. This was followed by what many on social media called the longest day ever, which included several strong aftershocks, choppy cell service, and emotional distress for many.

Governor Wanda Vázquez Garced declared a state of emergency on Tuesday, and that same night, president Donald Trump signed it into effect. It is important to note that the initial declaration only covers immediate needs and not full damage assessment, which will be expected later, although it is not clear when or what will actually happen. There are calls by local leaders whose municipalities were impacted to have the federal government declare a federal disaster zone.

Similar to when Hurricane María hit in 2017, it’s been the united communities that have helped those struck harder by the earthquakes get through. But in times of an unprecedented and unpredictable crisis like this, people are also scared, moody, and paranoid.

Twitter, Facebook, and WhatsApp are being used as primary sources of important information, memes, and real-time reactions to the ongoing seismic event.

Social Media and Misinformation

When it comes to disaster situations such as hurricanes or earthquakes, people tend to rely on the use of social media to get quick information.

Before María struck, Puerto Ricans relied on the Facebook Live videos that local meteorologist Ada Monzón would publish daily to get accurate information on the trajectory of the hurricane. But at the same time, rumors like the “first ever Category 6 Hurricane” or conspiracy theories began to make social media rounds, especially through WhatsApp.

Similarly, during the Summer of 2019 protests, rumors about former governor Ricardo Rosselló’s resignation —weeks before it actually happened— were circulating through the same sites.

And since the beginning of the continuous seismic activity that began during the last days of 2019, so did inaccurate facts about what to do during a crisis, false “8.0 magnitude” earthquake predictions, and fracking in the southern coast conspiracy theories.

It’s important to note that the most reliable sources of information during emergencies are government agencies and experts on the topic.

Organizations like the Red Sísmica de Puerto Rico and Central Meteorológica y Geológica del Caribe, and experts like José Molinelli and Víctor Huérfano post quick and accurate information on earthquakes and meteorological events.

It’s important you trust experts and not what the friend of a friend forwarded through WhatsApp.


Although the major earthquake rocked the entire island, most of the damage has been concentrated on the south and southwest regions of the island, near the epicenter. People in the southern municipalities have been sleeping in their cars, makeshift tents, and shelters, due to collapsed homes, or fear of their homes collapsing. The main areas impacted are Guánica, Guayanilla, Yauco, Peñuelas and the city of Ponce.

There have also been multiple reports of bad cell service, and water and electric power aren’t expected to come back for a while. A Thursday morning CBS News report showed the damage to Costa Sur, one of the island’s most important power plants.

Meanwhile, parts of the Metropolitan Area in San Juan, Carolina, and Guaynabo have already had power and water service restored, meaning some people are beginning to see the island as business as usual.

It’s clear that the earthquakes didn’t hit everybody equally, and it’s the poorer communities who have no choice but to build houses that aren’t up to regulation that have lost everything. Instead of using social media to rub salt on the wound and flaunt non-existent engineering and construction experience, donate to local organizations or help rebuild homes.

Meanwhile, it is expected that aftershocks and more seismic activity will continue, heightening concerns about conditions getting worse. In fact, there were at least six aftershocks recorded on Thursday morning.
