A series of aftershocks followed across the country. A 5.0-magnitude aftershock struck 27 kilometers (about 16.8 miles) south-southwest of Nuevo de Julio, about 1,000 kilometers (620 miles) east of the first earthquake and about 20 minutes later.
Then, a 4.9-magnitude earthquake occurred in the same area as the first, followed by a 5.3-magnitude earthquake.
Earthquakes of magnitude 4.9, 5.0, and 5.3 are considered aftershocks because they are smaller in size than the main earthquake and in the same area.
Based on available data, there is no risk of a tsunami at this time, according to the Pacific Tsunami Warning Center (PTWC).
San Juan Governor Sergio Unac urged people to remain calm after the earthquakes.
“Let us apply all measures that we have learned to prevent accidents, while we are committed to knowing the impact (of the earthquake) to cooperate in everything necessary,” he wrote on Twitter.
UNAC added that the district is working with civil and security forces to respond, as well as with municipalities to respond to “taking care of them.”
In its initial statement, PTWC recorded the depth of the earthquake at about 20 kilometers (12.43 miles).
CNN correspondent said Espanol, Agustina Montaño in San Juan, it was a “strong” earthquake, adding that everything fell on the shelves of his house.
This is a developing story, more to come.
