Unfortunately, natural disasters like the recent landslide in Washington state serve as a reminder of the unexpected and potentially devastating events that can occur. This landslide, which is one of the deadliest in US history, was not entirely unexpected as the area, known as Slidehill, has been identified as a potential risk since the 1960s. Despite warnings, there were still significant losses and ongoing uncertainty regarding the number of missing individuals. It's essential to be aware of potential risks in our surroundings and take necessary precautions where possible.

    • Understanding Mass Movements: Landslides and MoreMass movements, including landslides, are natural phenomena caused by gravity overcoming friction. Human activities can increase the risk, but people have the right to live where they choose. Awareness and preparation are key to mitigating potential damage.

      Mass movements, including landslides and mudslides, are natural geological phenomena caused by gravity overcoming friction. These movements can occur on various scales and can be triggered by various factors, such as water or earthquakes. Landslides are a type of mass movement characterized by fast soil movement off of bedrock. Other types include creeps, which are slow movements, and slumps and flows. The risk of mass movements can be increased by human activities, such as building homes on unstable land. It's important to be aware of the potential risks and take necessary precautions, but ultimately, people have the right to make their own decisions regarding where they live. The 2023 California landslide, which covered about a square mile and was 15 feet deep, was a devastating example of this natural process. While some may argue that those affected should have known better, it's important to remember that not everyone may have been fully aware of the potential risks. Additionally, it's important to note that mass movements can occur in areas where they have happened before, making it crucial for individuals and communities to stay informed and prepared.

    • Understanding Earth's constant soil and rock movements: creep, slump, and flowSoil and rock movements like creep, slump, and flow are natural processes caused by water, shaping the earth's surface over time. Understanding these movements' causes and consequences is crucial for safety and infrastructure planning.

      The earth's surface is constantly changing, and this change can manifest in various forms, including creep, slump, and flow. These mass movements can be caused by water, which can both stabilize and destabilize soil, depending on the amount. Creep refers to the slow, continuous movement of soil or rock over a long period, often unnoticed. A slump, on the other hand, is a sudden, large-scale movement of soil or rock, usually triggered by water or the inability of the base to support the weight above it. Lastly, flow is a fast-moving mixture of water and soil or rock, which can be particularly deadly. It's essential to understand that these mass movements are the result of long-term weathering and erosion processes, even if the actual event may seem sudden.

    • The interconnected processes of weathering and erosion shape the Earth's landscapeWeathering breaks down rocks and materials, making them susceptible to erosion by natural forces such as water, wind, gravity, waves, and glaciers, ultimately leading to landslides and other forms of mass movement.

      Weathering and erosion are interconnected processes that shape the Earth's landscape. Weathering refers to the various physical and chemical processes that break down rocks and other materials, making them more susceptible to movement. Erosion, on the other hand, is the movement of weathered material due to natural forces such as water, wind, gravity, waves, and glaciers. The two main types of weathering are mechanical, where the material retains its original chemical composition despite being broken down, and chemical, where the material undergoes a fundamental change in composition. Weathering is crucial because it makes the land more prone to landslides and other forms of mass movement, particularly in extreme environments. A notable example of this is the aftermath of a landslide, where the deposited sediment, known as talus, can be seen at the base of the hill. The constant cycle of weathering, erosion, and deposition is a fundamental aspect of the Earth's geology. A poignant reminder of this process can be found in the aftermath of a landslide, where the devastating impact of these natural forces becomes clear.

    • Natural occurrences causing mass movementsHeavy rainfall, earthquakes, and wildfires can trigger landslides by weakening the ground's stability, making it more prone to sliding

      Mass movements, such as landslides, are triggered by various factors that suddenly and rapidly cause gravity to overcome friction. These triggers can include heavy rainfall, earthquakes, and wildfires. For example, water saturates the ground, making it heavy and prone to sliding. Earthquakes vibrate the Earth's crust, disrupting friction. Wildfires burn vegetation, leaving behind unstable soil and pockets that make the ground more susceptible to landslides. These natural occurrences demonstrate how even small changes can lead to significant and sometimes catastrophic events.

    • Landslides after wildfires and volcanic eruptionsWildfires weaken trees and make land unstable, volcanic eruptions trigger pyroclastic flows and lahars, both causing devastating landslides, and landslides can cause flooding by damming rivers or creating dams that break.

      Landslides can occur long after wildfires and volcanic eruptions, leading to devastating consequences. Wildfires can weaken the roots of trees, making the land more unstable. Volcanic eruptions can trigger two types of flows that contribute to landslides: pyroclastic flows and lahars. Pyroclastic flows are fast and deadly, reaching speeds of 450 miles an hour and temperatures over 1500 degrees Fahrenheit. Lahars are slower but more voluminous, moving at 20 to 40 miles an hour and carrying large boulders. They are often triggered by water and occur near stratovolcanoes. Volcanic soil is loose and unstable, turning to slurry with water, and eruptions can shake the ground, causing landslides. The Mount St. Helens eruption in 1980 is a well-known example, causing a landslide that traveled at 150 miles an hour and destroyed 27 bridges, about 200 homes, and miles of road. Additionally, landslides can cause flooding by damming rivers or creating dams that can break, leading to downstream flooding.

    • Historical natural disasters with devastating consequencesNatural disasters can cause significant damage and loss of life, but not everyone is affected. Being aware of natural hazards and taking necessary precautions can help minimize their impact.

      Natural disasters can have devastating consequences, as seen in various historical events such as the most expensive landslide in US history in Thistle, Utah in 1984, and the Lake Peigneur disaster in Louisiana in 1980. These events, including the Thistle landslide that dammed up the Spanish Fork River and caused flooding, and the Lake Peigneur disaster triggered by a drilling accident that caused a whirlpool and sucked in surrounding land and barges, demonstrate the destructive power of nature and the potential for significant damage and loss of life. Despite the severity of these events, it is remarkable that not everyone lost their lives, as was the case in the Lake Peigneur disaster where only one person and possibly three dogs died. These disasters serve as reminders of the importance of being aware of natural hazards and taking necessary precautions to minimize their impact.

    • Landslides: A costly and deadly natural disasterLandslides cause thousands of deaths and billions in damage annually, primarily in mountainous regions with heavy rainfall. Humans contribute significantly to the risk through activities like deforestation and road building, and landslide damage is not typically covered by insurance.

      Landslides are a significant natural disaster, causing thousands of deaths and billions of dollars in damage each year, primarily in areas with mountainous terrain and heavy rainfall. Human activities, such as deforestation, road building, and mining, can exacerbate the risk of landslides. While some causes are natural, like earthquakes and animal activity, humans are the leading instigators. Interestingly, in the United States, landslides are the most expensive natural disaster, costing more than tornadoes and earthquakes combined. Despite this, landslide damage is typically not covered by homeowners insurance. To mitigate the risk of landslides, measures such as drainage pipes, permeable membranes, retaining walls, and reforestation can be implemented during construction projects. However, there is currently no law requiring that an equal or greater number of trees be planted when timber is harvested. This is a missed opportunity for prevention and mitigation.

    • Georgia's 'Slowpoke Bill' and European Driving HabitsGeorgia's new law aims to prevent slow drivers from obstructing fast lanes, while Europeans typically use left lanes for passing only.

      Georgia's new "slowpoke bill" aims to reduce traffic congestion by making it illegal to impede the flow of traffic in the fast lane, even if you're going the speed limit. This law, while subjective and potentially difficult to enforce, is seen as a bold step to keep traffic moving smoothly in a state known for its fast drivers. Meanwhile, in other parts of the world like Europe, the left lane is traditionally used for passing only.

    Dr. Gio Roberti's Bio

    Dr. Gio Roberti is Section Head, Natural Hazards at Minerva Intelligence in Vancouver, BC, Canada. At Simon Fraser University website, where he did his PhD, in the Centre for Natural Hazards Research section, he has specialised in Quaternary geology and Landslide modelling. He is currently working in the application of artificial intelligence (AI) approaches to the automated identification and risk assessment of geohazards such as landslides. Dr. Roberti has also studied the effects of climate change on the stability of glaciated volcanoes. His main test site was the Mt Meager volcano, near Squamish and Whistler, just north of Vancouver, British Columbia, Canada. During the summer of 2010, snow and ice melt caused the collapse of Mt. Meager's south flank generating the largest historical landslide in Canada. Using remote, field and numerical techniques Dr. Roberti did in-depth study of such landslides and glacial activity, as well as their influence on the deeper volcanic system.
