Divya Delhi: A massive earthquake with a magnitude of 7.5 rocked South America, and the potential of a tsunami was being evaluated. When the United States Geological Survey (USGS) decided that the earthquake's magnitude was 7.5, it was lowered from its original designation of 8.0. The US Geological Survey reports that at least 15 aftershocks followed the earthquake, which occurred 15 kilometers (9.3 miles) north of Poso district in Central Sulawesi province. There was no tsunami warning issued by Indonesian authorities. The majority of the injured, who were primarily churchgoers attending a Sunday morning worship session, have already been transported to the regional government hospital, according to Indonesia's National Disaster Mitigation Agency. When a powerful 8.8-magnitude earthquake occurred in the eastern Kamchatka region of Russia in July, tsunami warnings were sent out for the whole Pacific. According to data, the earthquake in Russia was one of the strongest earthquakes ever recorded in the modern age.
