Earthquakes, Cracks And Fears In Grenada
2021-01-31 | by CusiGO
Cracks and fear are two direct effects of earthquakes. When they last for a few days, they all multiply. This happened a week ago in Granada Province, where the National Institute of geology detected 740 earthquakes between January 23 and Saturday morning, five of which were more than magnitude 4 and 21 more than magnitude 3. Just look at the street and you can see the consequences: a fear spreads between some of the population and many of the broken buildings, which, according to a capital earthquake expert, may be more serious than the first review showed. At present, there is no calculation of the economic losses caused.
Manuela, 81, walked to mass in Santa Fe, a city of 15000 residents just 10 kilometers from Granada, the epicenter of several earthquakes. The woman cried and only asked how she was. “I’m scared. “Every day he’s moving the floor, I don’t know what to do,” he said, and then he blamed himself for not being calm. “I’m not worth a cent,” in a word, on a nearby street, under a damaged building, pepy and his teenage daughter bet.
The 44 year old housewife said her family still dare not sleep on the top floor of her two-story house with cracks. From Tuesday, when a series of three strong earthquakes hit the province, she, her husband and two daughters slept on the living room sofa as much as possible. “The children are very anxious these days,” PEPI stressed.
In Santa Fe and in atafi, another town affected, the city council has set up victim assistance offices. According to the mayor, 130 families have submitted documents about 500 damaged homes in Santa Fe and atafi. Grenada, by contrast, has no official data.
In addition to these records of damage, damage to schools, supermarkets and heritage areas such as Alhambra and some churches, including the capital Cathedral, must be added. With the exception of an area in Alhambra, the official statement after preliminary analysis is that the losses are “minor, not structural.”. But Enrique Hern á ndez Montes, a professor of structural mechanics at the University of Granada and an expert on building earthquake resistance, is not optimistic.
In analyzing the consequences, Hernandez Montes focused on the basic seismic acceleration or, more simply, on the horizontal thrust at the bottom of the building. The professor explained that regulations in Grenada and other regions require buildings to withstand an earthquake of 0.24 grams, compared with 0.20 grams in Santa Fe on Thursday night. This means, he added, that the earthquake is approaching, bringing many buildings “very close to their limits” and almost certainly affecting some buildings structurally, especially old ones. Therefore, Hernandez suggested not to stay on the superficial review, and urged in-depth review. Considering that the equivalent value of the capital is 0.15 g, the possibility of serious damage is reduced, compared with 0.36 g for the 2011 Loka earthquake.
Pilar, a neighbor of Santa Fe, said her house “cracked.”. She gets nervous at the thought of what happened these days. For several days, he had been sleeping in an open space in the car with his four children. He had an insurmountable fear, he said.
Jes ú s IB á nianez, a professor at the University of Granada and an earthquake risk expert, believes that recent events in Granada are “normal.”. “We’ve had shows like this before.” He recalled that a series of events occurred in Loja in 1983, which lasted for two or three months, and a series of events occurred in Granada from March to October 1979. It could happen again, he said.
The first damage inspection after the earthquake was carried out by firefighters. Gustavo Molinos is the owner of Granada and the metropolitan area. So far, he said, they have received more than 100 calls, but “nothing but cracks and faults.”. “If there is any danger, we will reinforce it. If not, we will use the lighthouse. The owner will fix it.”
Local and autonomous governments have earthquake emergency plans, as recently happened. But Professor Jesus í s IB á niez complains that these people are not trying to cultivate a population, “in the United States, but in Guatemala or Nicaraguan, children know how to express themselves in this situation. There has never been a real earthquake drill. Well, one day the politicians will come, “he said. This will help “calm.”. In fact, ibanese objected to the municipal authorities encouraging open parks and homeless people to spend the night outside. “Mayors should not underestimate that, but they should put it in the background.” The background here, he concluded, is that intensity 4 is not worrying.
