One day Conurbano shuddered. At the site where the highest population density is concentrated in the country, more specifically to the south of the region, the country was moving, Millions of Buenos Aires perceived it and – sign of times – into social networks to express fear, wonder or confusion.
The huge social consequence corresponds one of the three most intense records the brief seismological history of the province of Buenos Aires. Observatory teams of the Faculty of Astronomy UNLP captured an earthquake at a local station at 10.27.44. The report reveals that "the epicenter is located in the province of Buenos Aires at a distance of about 30 km from La Plata" and that it has a size of 3.8 points
"There is no common earthquake in the province of Buenos Aires, but there are precedents: in 2016 there were two in the Olavarría area, which was similar in size, about 4 points on the scale, he said Clarin, Nora Sabbione, Head of the Department of Seismology and Meteorological Information of the Faculty of Astronomy and Geophysical Sciences, UNLP
He was also among the strongest in the region. The River Plate is the largest record 5.5 points occurred in 1888 and captured in details of Río de la Plata, Sabbione. And with an intensity very similar to the intensity of this Friday, it appeared in November 2016 north of Montevideo. They are only close background episodes recorded in the River Plate area.
Sabbione concentrated his work team in his offices in the Platens forest to analyze all the data of the measuring instruments when the first consequences of the earthquake that hit the morning occurred.
A technical explanation of this phenomenon: "It was an inland earthquake. These are mistakes that interrupt the ground caused by plate movements. In this case, the rupture was recorded at a depth of 25 kilometers, within what we call the Earth's crust, "Sabbione added.
Source, origin of the movement is tectonic, or be naturalIt's not a man-made noise, it's not a wind. "Seismology registers another type of noise, but this signal is captured by our teams and the Institute of Seismology it is clearly an earthquake, movement in the interior of the country. We can assure it by form, frequency, waves. There was no human intervention here. It was a natural phenomenon: an earthquake"he repeated, so there was no doubt.
"According to our teams, it took time for more than four seconds, When this size is negligible, there are no changes. Perception is similar to rumor or intense noise, movement. And after four or five seconds, even more, "said UNLP expert.
This type of demonstration can not be predicted because there are no previous indications. That is, they hit without warning. And they cause fear and worry. Also other moves, but people. In the building of the Buenos Aires prison service (5 between 35 and 36 years) evacuated the body after moving and found a rupture in the floor.
Sabbione assures, however, that there are no risks for the population. "With this intensity there is no possibility of collapse or the fall of the masonry"Everything will return to normal in Buenos Aires, when the shock that he trembles.
