A rogue wave recorded off the west coast of Canada in 2024 has been confirmed as the most extreme ever officially measured. The wave, which reached about four storeys high, was detected by a buoy operated by Marine Labs near Ucluelet, British Columbia. It was roughly three times the height of the waves around it and did not cause any injuries or damage. Researchers at the University of Victoria analyzed the data and confirmed it was not a technical error.
Rogue waves are defined as waves more than twice as tall as the waves surrounding them. They can appear suddenly in stormy seas or in relatively calm water and are known to pose risks to ships and offshore structures. Scientists have documented accounts of such waves for centuries, though these reports were often met with skepticism. A wave recorded in the North Sea in 1995, known as the Draupner wave, was the first to be officially confirmed by instruments and helped establish rogue waves as a recognized phenomenon.
The cause of rogue waves is not fully understood. One explanation is that waves traveling at different speeds can combine and temporarily form a much larger wave. Another theory involves groups of waves exchanging energy, which can also produce an extreme wave. Recent research suggests that strong winds over young waves play a significant role in their formation. A study conducted near Antarctica found that rogue waves occurred roughly once every six hours when winds were strong, and were not observed in calmer conditions.
Scientists have also studied how waves meeting from different directions can create unusually tall waves. Laboratory experiments have shown that when waves converge at wide angles, they can continue to grow even after breaking, becoming steeper than previously thought possible. This research may inform future designs for offshore infrastructure such as wind turbines and oil platforms.
Rogue waves are distinct from tsunamis, which are caused by displacement of the entire water column, typically from earthquakes, volcanic eruptions, or landslides. Rogue waves form at the surface, although similar phenomena can occur deep underwater.
Separately, researchers have identified a fault line in northwestern Canada that may pose a greater earthquake risk than previously recognized. The Tintina Fault runs beneath Dawson City in the Yukon, a town of about 1,600 residents. For decades, the fault was believed to have been inactive for tens of millions of years. However, recent studies suggest that the fault has accumulated roughly 20 feet of strain and could produce an earthquake of magnitude 7.5 if that tension is released at once. Such an earthquake would be capable of damaging roads and unreinforced buildings, though the region’s remote location would limit the scope of impact.
The Tintina Fault is not currently listed on Canada’s official seismic hazard map. Researchers are using satellite data, trench excavations, and land surveys to better understand the fault’s history and whether it poses an immediate threat. They caution that long periods of quiet do not necessarily indicate whether a fault is preparing for a large event or slowly releasing stress. While the fault’s status remains uncertain, scientists recommend preparedness measures such as reinforced construction and updated hazard assessments.
In another development, geologists studying the ocean floor near Madagascar have documented a large underwater volcano that formed after a deep earthquake in 2018. The volcano, which rises about 2,700 feet from the seafloor, was discovered during an expedition following increased seismic activity in the area. Between February and May 2019, instruments recorded roughly 17,000 seismic events beneath the ocean floor, an unusually high number. The findings suggest that magma reservoirs and drainage systems exist deep within the Earth’s crust, and that large eruptions can occur in relatively short periods.
Underwater volcanoes are common, with most volcanic activity on Earth occurring beneath the ocean. When magma reaches the seafloor, it cools rapidly and can eventually build up over time to form islands. These volcanic islands often develop unique ecosystems because of their isolation. One notable example is the island of Oshima in Japan, where a city was built within the crater of an active volcano. The volcano last erupted in 1785, and while residents were evacuated at the time, the island remains inhabited today with continuous monitoring.
Scientists have also reported significant interest in naturally occurring hydrogen gas beneath the Canadian Shield, an ancient geological formation stretching across much of Canada. Researchers from the University of Toronto and the University of Ottawa have measured hydrogen flowing continuously from underground holes near Timmins, Ontario. This so-called white hydrogen is produced naturally when water interacts with iron-rich rocks deep underground. Unlike industrial hydrogen, which is typically made from fossil fuels or renewable electricity, white hydrogen may offer a cleaner source of energy.
The discovery has attracted attention from the energy industry, though significant questions remain about the size of the underground reservoirs and whether the gas can be extracted at commercial scale. Hydrogen is difficult to store and transport because its molecules are very small and can leak easily. While some experts compare the potential of white hydrogen to the early days of the oil industry, others caution that the hype is moving faster than the science. Further drilling and study will be needed to determine whether the Canadian Shield can become a meaningful source of hydrogen.
The Canadian Arctic is receiving renewed attention for its mineral resources, which are essential for electric vehicle batteries, electronics, and defense technologies. The region contains deposits of lithium, graphite, nickel, cobalt, copper, and rare earth elements. Canada has introduced a critical minerals strategy with billions in funding to support mining and processing operations. The country already produces more than 60 minerals and metals, and officials hope to build domestic supply chains that reduce reliance on foreign processors, particularly China, which refines most of the world’s rare earths.
Mining in the Arctic faces significant challenges, including extreme cold, remote locations, and limited infrastructure. Many mineral deposits are located on Indigenous lands, which requires consultation and consent from local communities. Some Indigenous-owned corporations are already participating in resource development. Advances in artificial intelligence are also helping geologists analyze decades-old rock samples to identify promising mineral deposits without new drilling. If successful, the Arctic could become a major supplier of critical minerals for North America, which could lower costs for batteries and other clean energy technologies over time.
Northern Ontario remains one of the least populated regions in Canada despite its large size. The area covers about 87 percent of the province but is home to only about 6 percent of its population. The region’s rugged landscape, remote location, harsh winters, and limited infrastructure make it difficult for communities to grow. Many towns have aging populations, and young people often leave for education or work in southern cities. The region does have a strong mining economy, particularly in gold and critical minerals, but mining companies struggle to find enough skilled workers. Local authorities are exploring incentives such as tax breaks and healthcare recruitment bonuses to attract new residents.
China has completed a major project to contain the Taklamakan Desert, the world’s second-largest shifting sand desert. The effort involved planting a belt of drought-resistant trees and shrubs around the desert’s edge, stretching about 2,000 miles. The project took 40 years to complete and involved hundreds of thousands of workers. Desertification has been a growing problem in China, with deserts expanding by more than 1,300 square miles per year at their peak. The green belt is designed to prevent sandstorms from reaching populated areas and to protect roads and railways. Officials report that the portion of the country covered by deserts has declined slightly since the project’s completion, though the long-term effectiveness of the effort remains to be seen.
Several island nations and coastal regions are facing increased risks from rising sea levels. The Maldives has built an artificial island called Hulhumalé, which sits about six feet above sea level and serves as a potential evacuation site during storms. Fiji is planting mangroves to reduce wind damage from cyclones and prevent coastal erosion. In Egypt, the coastal city of Alexandria faces flood risks, with nearly half its population living below sea level. The Netherlands, which already has extensive experience with flood management, is expected to rely on storm barriers and seawalls. Tuvalu, an island chain in the Pacific, is considered among the most vulnerable countries, with much of its land only a few feet above sea level. The Philippines, Vanuatu, the Marshall Islands, and other Pacific nations are also taking steps to fortify infrastructure and relocate communities to higher ground.
Scientists have also been examining the risks posed by large-scale geological events. An earthquake of magnitude 9.5, the most powerful ever recorded, struck Chile in 1960 and slightly altered the length of the day. While earthquakes above magnitude 10 are theoretically possible, scientists say the Earth’s crust does not contain enough stored energy to produce an event of magnitude 15, which would be capable of causing global devastation. The most destructive earthquakes occur along the Ring of Fire, a zone of intense tectonic activity around the Pacific Ocean where most of the world’s earthquakes and active volcanoes are located.
Underwater avalanches, known as turbidity currents, are another natural hazard that can cause significant damage. These flows of sediment and water move rapidly along the ocean floor and have been known to break seabed communication cables. In 1929, an earthquake off the coast of Newfoundland triggered an underwater avalanche that snapped 11 cables and produced a tsunami that killed 28 people. In 2006, an earthquake near Taiwan cut multiple undersea cables, disrupting internet traffic across Southeast Asia. Researchers have been studying these events using seafloor mapping and 3D models to better understand how they begin and how they can be predicted.
Fossils from the Cambrian period, which lasted from about 541 to 485 million years ago, have provided a window into the early evolution of complex life. One creature, known as Mosura, was a small arthropod with three eyes, a cone-shaped mouth, and claws that may have been used to capture prey. Despite its tiny size, it is considered one of the more distinctive predators of its era. Another ancient organism, Prototaxites, stood up to 26 feet tall and may have been neither a plant nor a fungus. Chemical analysis has suggested it belonged to an unknown branch of life that existed before the major kingdoms of organisms were established.
A large piece of continental crust has been identified beneath the Davis Strait between Greenland and Canada. The formation, described as a proto-microcontinent, is about 12 to 15 miles across and lies roughly 6,500 feet underwater. It began to break away from the larger landmass between 58 and 49 million years ago, but the separation stalled, leaving the chunk stranded beneath the ocean. Scientists say the discovery offers insight into how continents break apart and why some fragments fail to fully separate. Similar formations, such as Zealandia near New Zealand, have raised questions about how continents are defined.
The Earth’s crust is in constant motion, and geological understanding continues to evolve as new data becomes available. Fault lines once considered inactive may warrant renewed attention, and natural resources once thought inaccessible may become viable with new technology. While the timeline for such changes remains uncertain, the evidence gathered so far points to a planet that is far more dynamic than static maps might suggest.
