Earthquakes

Unlike regular wind-generated sea waves, which usually have wavelengths of about 300 to 600 feet, tsunami waves can have wavelengths of about 300 to 600 miles in the deep ocean

A 6.1 magnitude earthquake struck near western Cuba on Monday, shaking buildings in Havana and beyond. No injuries or damage were immediately reported. The quake struck at a depth of 10 kilometres in waters just west of the capital, according to the US Geological Survey. Flavia Pupo, a manager at the Pinar del Rio hotel, in Pinar del Rio, described how the building shook and caused some fear. "Everyone here is OK," she said by telephone. "The people on the street are a little bit scared." The latest earthquake was felt as far away as Florida. The National Weather Service in Miami said in a tweet that it received several reports of shaking in the southwestern part of the state. The Oriente fault zone is located just off Cuba's southeast coast and has unleashed damaging earthquakes in recent centuries, including a 7.7 magnitude quake on January 2020 in open waters that caused damage in Cuba and the Cayman Islands.

Numerous aftershocks followed the 7:37 am Monday quake, which was felt in nearby Malaysia. Tsunami waves were also detected in Indonesia and Malaysia

Tremors were felt across Sikkim and parts of north Bengal after a 5.6-magnitude earthquake struck Bhutan late on Sunday, officials said. Tremors lasted for a few seconds, and there was no immediate report of any loss of life or property damage in these states, they said. According to the United States Geological Survey, the earthquake took place at 11.06 pm near Punakha in Bhutan. Residents in Gangtok and other parts of Sikkim said they felt tremors for a few seconds, prompting many to rush out of their homes as a precaution. A Sikkim State Disaster Management Authority official said the situation is being monitored. People in some places of Siliguri city and in Cooch Behar, Jalpaiguri and Alipurduar districts in West Bengal said they felt the tremors and came out of their residences. There was no report of injury to any person or damage to property in these places of north Bengal adjoining Bhutan, the officials said.

A 5.2 magnitude earthquake struck south China's Guangxi region early Monday, killing two people, toppling buildings and triggering the evacuations of thousands, state media reported. Four others were injured, while more than 7,000 residents were evacuated from Liuzhou city. The search for several missing residents wrapped up around midday Monday, after the last trapped person, a 91-year-old man, was found alive in good condition, authorities said. Images aired by state broadcaster CCTV showed excavators clearing debris. At least 13 buildings collapsed, while landslides triggered by the quake blocked roads to the area, according to CCTV. Train services around Liuzhou were cancelled or delayed. Earthquakes occasionally strike south China, with more intense ones usually occurring toward the mountainous west or the east, toward Taiwan. The most devastating recent earthquake with a magnitude of 7.9 occurred in the southwestern Sichuan province in 2008, leaving more than 87,000 dead or

The quake occurred at a shallow depth of 150 km, with the epicentre located at latitude 36.722 N and longitude 74.456 E

A magnitude 6.2 earthquake shook part of northern Japan early Monday, but no damage or casualties have been reported. No tsunami advisory was issued by the Japan Meteorological Agency. The quake struck 18 kilometres west of the small town of Sarabetsu on Japan's northernmost main island of Hokkaido at a depth of 81 kilometres, according to the US Geological Survey. It measured the quake's strength at 6.1 magnitude. A week ago, a 7.7 magnitude earthquake prompted Japan to issue an advisory of a slightly higher risk of a possible megaquake for the nation's northeastern coastal areas.

The earthquake originated at a depth of 62 kilometres beneath the surface, indicating a moderately deep seismic event

A powerful earthquake struck off the northern Japanese coast, and the Japan Meteorological Agency issued a tsunami alert in the region. The quake, registering a preliminary magnitude of 7.4, occurred off the coast of Sanriku in northern Japan at around 4:53 pm (0753 GMT), at a depth of about 10 kilometres (6 miles) below the sea surface, the agency said.

A magnitude 5.7 earthquake struck a rural part of Nevada east of the state's capital of Carson City on Monday. The temblor hit just before 6:30 p.m., the US Geological Survey said. It was centred 20.7 kilometres east of the town of Silver Springs at a depth of 5 kilometres. Video shot in the town of Fallon showed shattered glass and food scattered on the floor in the aisles of a grocery store. Trina Enloe was sitting with one of her daughters as she did homework in their dining room when the quake hit. "You could hear the rumbling just coming before it even got to us," Enloe said. The shaking continued for about a minute, she said. The jolt knocked over some cast iron candle holders but Enloe didn't see any cracks or damage in her home in Fallon. The USGS said some residents in nearby communities reported strong to very strong shaking and light to moderate damage.

An earthquake in Indonesian waters set off small tsunami waves Thursday morning, killing at least one person and damaging houses and buildings, officials said. The 7.4 magnitude earthquake was centred in the Molucca Sea at a depth of 35 km, the US Geological Survey said. Tsunami waves were recorded at several monitoring stations less than half-an-hour later, including in Bitung with a height of 8 inches and in West Halmahera with a height of a foot, according to Indonesia's Meteorology, Climatology and Geophysics Agency. The Pacific Tsunami Warning Center in Honolulu said waves of 2 inches were recorded in Davao in the southern Philippines, but there was no threat for more distant areas about three hours after the quake. Strong shaking lasting 10 to 20 seconds was felt in Bitung, a coastal city in North Sulawesi province, and surrounding areas, as well as in Ternate city in neighbouring North Maluku province, according to Indonesia's Disaster Management Agency.

A strong preliminary magnitude 7.6 earthquake struck near Tonga in the South Pacific Ocean on Tuesday. The United States Geological Survey said the quake struck early Tuesday evening local time at a depth of about 237 km. Earthquakes at shallower depths are felt more strongly at the surface.

A moderately strong earthquake struck central Turkiye on Friday, Turkiye's emergency response said. The tremor sent some residents rushing into the streets but no damage has been reported. The magnitude 5.5 quake was centred in the town of Niksar in Tokat province, at a depth of 6.4 kilometers (4 miles), according to the Disaster and Emergency Management agency, AFAD.
