Scientists Say A Major Earthquake Fault Line Is Waking Up
High up in Canada's Yukon Territory, a seismic gun is being cocked and aimed at the little community of Dawson City—population 1,600. If a new study in the journal Geophysical Research Letters is correct, that town or one of many others in the region could be rocked by a major earthquake pretty much at any moment. The source of the danger is a 1,000 km (620 mi.) formation known as the Tintina fault that cuts northwest across the Yukon and terminates in Alaska. It has been mostly still for the past 12,000 years but appears to be getting ready to lurch to life. 'Over the past couple of decades there have been a few small earthquakes of magnitude 3 to 4 detected along the Tintina Fault, but nothing to suggest it is capable of large ruptures,' said Theron Finley, a recent PhD graduate at Canada's University of Victoria and the lead author of the study, in a statement. That's not the full story, though, Finley says. What the last few decades suggest and what the geological record now shows are two different things—and according to the paper, Tintina is a lot more menacing than it seems. What caught the interest of Finley and his colleagues is a 130-km (80 mi.) segment of the fault that runs near Dawson City, with surface features suggesting that numerous large earthquakes occurred in relatively recent geological history—during the Quaternary Period, which runs from 2.6 million years ago to the present. To get a better understanding, the researchers used an existing library of high-resolution imagery from airplanes, satellites, and drones, some of them captured by lidar—which uses pulsed laser emissions to produce 3D maps of the surface. This allowed them to study that stretch of the fault in unprecedented detail—and find a number of geological secrets hiding in plain sight. At one point in the Tintina segment, they discovered a fault scarp—or a ridged crack in the surface—where the land broke and shifted by 1,000 m (3,280 ft.). That is a clear fingerprint of an earthquake, one that, according to the rounding and wear and sloping of the scarp, occurred about 2.6 million years ago. At another spot they found another scarp, misaligned by a more modest 75 m (250 ft.), that they estimate to have been caused by a smaller but still considerable quake that occurred about 132,000 years ago. No evidence of significant quakes turned up at any time in the past 12,000 years, meaning Tintina has been relatively stable throughout the entirety of the Holocene Epoch, which runs from 11,700 years ago to the present. But for modern day folks living in Dawson and elsewhere, that recent period of quiescence is actually bad news. Just because a fault isn't causing quakes doesn't mean it isn't on the move. Finley and his colleagues estimate that Tintina is moving and accumulating strain on the order of 0.2 mm to 0.8 mm a year. Over the course of 12,000 years, those millimeters add up, and when the strain is suddenly released—which it ultimately must be—the result will not be pretty. "We determined that future earthquakes on the Tintina fault could exceed magnitude 7.5,' said Finley in a statement. 'Based on the data, we think that the fault may be at a relatively late stage of a seismic cycle, having accrued a slip deficit, or build-up of strain, of six metres [20 ft] in the last 12,000 years. If this were to be released, it would cause a significant earthquake.' The estimated 7.5 magnitude of the quake would put it on a scale with some of history's bigger temblors, including China's 1976 Tangshan event which claimed an estimated 240,000 to 650,000 lives; and the 2020 Haiti quake, which killed 300,000. The Yukon Territory is much more sparsely populated than Tangshen or Haiti, meaning fewer casualties. Still, there would quite likely be deaths, along with damage to local highways, mines, and other infrastructure. The area is also prone to landslides which could be triggered by a quake. 'Our results,' the researchers wrote, 'have significant implications for seismic hazard in the Yukon Territory and neighboring Alaska. If 12,000 years have elapsed since the last major earthquake, the fault may be at an advanced stage of strain accumulation.' It is impossible to know exactly when that strain will be released, of course—one of the things that makes seismology such a confounding science. The best the scientists can do is warn locals of the long term risks and leave them to prepare go bags, survival kits, and evacuation plans. The Earth will quake at will; we can only react.

Extreme weather turns Beijing into rain trap, kills at least 30
Extreme weather killed at least 30 people in Beijing after a year's worth of rain fell in a matter of days, stretching the Chinese capital's disaster management capabilities and prompting some experts to call the city a rain trap. Much of the rain inundated Beijing's mountainous north near the Great Wall, with 28 deaths reported in the district of Miyun and two in Yanqing, the official Xinhua news agency said on Tuesday. It did not say when or how the deaths occurred. Heavy rain started last Wednesday and intensified around Beijing and surrounding provinces on Monday, with the capital experiencing rainfall of up to 543.4 mm (21.4 inches) in its northern districts, Xinhua said. The average annual rainfall in Beijing is around 600 mm. "The cumulative amount of precipitation has been extremely high - reaching 80–90% of the annual total in just a few days in some areas," said Xuebin Zhang of the University of Victoria in Canada and CEO of the Pacific Climate Impacts Consortium (PCIC). "Very few systems are designed to handle such an intense volume of rainfall over such a short period," Zhang said. The local topography - mountains to the west and north - "trapped" the moist air and forced it to rise, enhancing the extraordinary amount of precipitation, he said. China's usually arid north has seen record precipitation in recent years, with some scientists linking the rainfall to global warming. In the summer of 2023, heavy rain and flooding killed at least 33 people in Beijing. Rainfall in the city of Xingtai in neighbouring Hebei province exceeded 1,000 mm in two days - double the yearly average. Late on Monday, President Xi Jinping said there had been "heavy casualties and property losses" in Beijing and the provinces of Hebei, Jilin and Shandong, and ordered "all-out" search and rescue efforts. More than 80,000 Beijing residents had been relocated, Xinhua reported, with roads and communication infrastructure damaged and power to 136 villages cut off overnight. The most intense rain occurred on Saturday in Beijing's hilly Huairou, which saw 95.3 mm of rain in one hour. In Miyun on Monday, some people were trapped at an elderly care centre as water levels rose close to the roof. Emergency rescue services swam into the building and used ropes to pull out 48 people. On Tuesday, parks, libraries and museums including the Palace Museum at the Forbidden City were closed. Train and bus services in the suburbs and along waterways were suspended. Hundreds of flights were cancelled or delayed at Beijing's two airports, state media reported. 'FLOOD STILL COMING' Heavy rain also pounded the province of Hebei and the city of Tianjin neighbouring Beijing, which are all part of the vast Hai river basin. Four people were killed in a landslide in Hebei on Monday, with eight still missing, as six months' worth of rain fell over the weekend. In two villages in Tianjin on Monday, major roads were flooded, bridges damaged, with only the roofs of single-storey houses visible, China Central Television (CCTV) reported. Heavy rain is expected to persist in parts of Beijing, Hebei and Tianjin on Tuesday, the emergency management ministry said Monday night, adding that "the disaster relief situation is complex and severe." Some residents in the region posted on social media platform Weibo calling on authorities to expedite rescue efforts.
