There were no immediate reports of injuries or damage after the 7.4 magnitude earthquake.A 7.4 magnitude earthquake struck northern Chile on Thursday. There were no immediate reports of injuries or damage.The quake struck 28 miles south of San Pedro Atacama at a depth of 72 miles, or 117 kilometers, according to the United States Geological Survey. San Pedro is a town in the Atacama desert that is a major tourist hub for northern Chile.This is a developing story. More

No injuries or deaths were immediately reported, but two buildings partially collapsed in the tremors, which followed a powerful April 3 quake that killed 17 people.Taiwan was shaken by a series of earthquakes on Monday and early Tuesday, the strongest with a magnitude of 6.3, partially toppling two buildings and keeping frightened residents up overnight. The tremors were aftershocks from the magnitude 7.4 quake that killed 17 people three weeks ago, the authorities said.The tremors began just after 5 p.m. on Monday local time with a 5.5 magnitude quake in Hualien County on Taiwan’s east coast, according to Wu Chien-fu, the director of the Taiwanese Central Weather Administration’s Seismological Center. It was followed by a series of smaller tremors some minutes later in the same area.Two buildings in the city of Hualien partially collapsed, some residents were evacuated and schools and offices in Hualien County were ordered to close on Tuesday because of the threat of continuing tremors, according to local news outlets. No injuries or deaths had been reported by Tuesday morning.Mr. Wu said at a news conference on Monday night that the quakes were aftershocks from the deadly April 3 quake, which was the strongest to hit Taiwan in 25 years. The epicenter of that earthquake was also in the Hualien County area.Maps: Earthquakes Shake Eastern TaiwanView the location of each quake’s epicenter and shake area.By Tuesday morning, more than 180 shocks had been recorded in the previous 24 hours, according to the Central Weather Administration. The strongest were at 2:26 a.m., at magnitude 6, off Taiwan’s eastern coast, and 2:32 a.m., at magnitude 6.3, about 10 miles from Hualien County. The latest big tremor came at about 8 a.m. on Tuesday, according to the Central Weather Administration.Chen Mei-hui, 58, a retired saleswoman who lives in Hualien, said the tremors had put her in a “very torturous mood.”“I have been unable to sleep well since the earthquake this month,” she said on Tuesday morning. “We can only pray that our house is strong enough to get us through this difficult time.”Chris Buckley More
Seismologists said that severe earthquakes are relatively rare around the city and cannot be predicted. But if one were to hit, it could inflict serious damage.The earthquake that hit the Northeast on Friday morning rattled nerves but did not do much damage. Still, it left many New Yorkers wondering how afraid they should be of a bigger one hitting closer to the city.The answer? It’s hard to say.Some news reports suggest that a large earthquake is “due” in New York City because moderate ones — with a magnitude of 5 or more — typically occur every few hundred years. The last one took place in the 1700s. Friday’s earthquake, in comparison, was a magnitude 4.8.In 2008, Columbia University’s Lamont-Doherty Earth Observatory found that the risk of earthquakes in the New York City area was greater than previously believed. That is because smaller earthquakes occur regularly in New York City, like a magnitude 1.7 earthquake that was recorded in Astoria, Queens, in January.Experts caution that it is impossible to know when an earthquake will strike or how much damage it might cause. But if an earthquake much stronger than Friday’s were to hit closer to New York City, “it would be a different story,” said Kishor S. Jaiswal, a research structural engineer with the U.S. Geological Survey. Forecasts from the city suggest that such a quake could result in dozens of injuries and billions of dollars in damage.There were few reports of damage or injuries after Friday’s earthquake. Still, city officials said they were inspecting bridges, train tracks and buildings, and that people should be prepared for aftershocks for at least several days. There were 29 aftershocks as of Saturday afternoon, including one with a magnitude of 3.8, according to U.S.G.S.Earthquakes with a similar magnitude to Friday’s are “rare, but they’re not unheard-of” close to New York City, said Leslie Sonder, an associate professor of earth sciences at Dartmouth College.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

And what else to know when the Earth moves.If you just felt the ground shaking, you might be wondering what happened or how to react the next time an earthquake strikes. Here are the answers to some common questions about earthquakes.What causes them?To understand earthquakes, imagine the Earth as an egg, said Mark Benthien, the communications director for the Statewide California Earthquake Center, a research organization.The egg’s shell represents the Earth’s crust, and “if you look at it from a worldwide view, there are 12 or so major egg pieces of the crust that are called plates,” Mr. Benthien said. Pieces of the egg’s shell — tectonic plates — move around slowly, about as quickly as your fingernails grow, building up pressure between them.Most earthquakes occur when the force of the moving tectonic plates exceeds the friction between them. When this happens, the pressure releases suddenly and plates move into, past or away from one another. The pressure is released as seismic waves that pass through the earth, causing the ground to shake.In rare cases, an earthquake can also occur in the interior of a tectonic plate.Earthquakes can also be caused by human action, such as the disposal of waste fluids as part of the process of oil production.Can earthquakes be predicted?No. It is not possible to predict where or when an earthquake might happen.However, national seismic hazard maps from the U.S. Geological Survey describe how many strong earthquakes are likely to happen in the next 10,000 years in the United States. More earthquakes with damaging shaking are likely to occur along the West Coast, along Alaska’s south coast and in parts of Hawaii, Puerto Rico and the Virgin Islands.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

The magnitude 7.4 earthquake in Taiwan on Wednesday was the strongest in 25 years, the island’s Central Weather Administration said.Here’s a look back at some of the major earthquakes in modern Taiwanese history:In September 1999, a 7.6 magnitude earthquake in central Taiwan killed nearly 2,500 people, the United States Geological Survey said. It was the second-deadliest in the island’s history, according to the U.S.G.S. and Taiwan’s Central Weather Administration. More than 10,000 people were injured and more than 100,000 homes were destroyed or damaged.Taiwan’s deadliest quake registered a magnitude of 7.1 and struck near the island’s west coast in April 1935, killing more than 3,200 people, the Central Weather Administration said. More than 12,000 others were injured and more than 50,000 homes were destroyed or damaged.A magnitude 7.3 earthquake in December 1941, which struck southwestern Taiwan, caused several hundred deaths, the U.S.G.S. said.A 6.4 magnitude earthquake in February 2016 caused a 17-story apartment complex in southwestern Taiwan to collapse, killing at least 114 people. The U.S.G.S. later said that 90 earthquakes of that scale or greater had occurred within 250 kilometers, or 155 miles, of that quake’s location over the previous 100 years. More
