Yellowstone’s Super Volcano Eruption Forecast

Yellowstone’s Super Volcano Eruption Forecast

Yellowstone's Volcanic Future: Insights from Recent Research

Meteorology Matters reviews research concerning volcanic activity at Yellowstone National Park. The sources provide insights into the likelihood of future eruptions, the structure of the magma system beneath the park, and the potential shift in volcanic activity.

Key Findings:

  • Yellowstone is not "overdue" for an eruption. Despite past supereruptions, volcanoes don't operate on predictable schedules. (Source: USGS)
  • The magma chamber under Yellowstone is largely solid. Only 5-15% is molten, raising questions about the feasibility of a large-scale eruption. (Source: USGS)
  • New research using magnetotellurics reveals a different picture of the magma system. Instead of one large reservoir, there are multiple, segregated pockets of magma with low melt percentages. (Source: Fox Weather & The Washington Post)
  • This finding suggests that eruptions are unlikely in the foreseeable future, particularly in the northeastern region. (Source: Fox Weather)
  • The research pinpoints the heat source driving Yellowstone's volcanic activity in the northeast region. This area also houses the largest magma storage, suggesting future eruptions may be concentrated there. (Source: Fox Weather)
  • The study confirms a shift in volcanic activity towards the northeast. This aligns with the movement of the North American plate over the Yellowstone hotspot. (Source: The Washington Post)
  • Scientists emphasize that future eruptions are likely thousands of years away. The park's volcanic activity is dynamic but does not pose an immediate threat. (Source: The Washington Post)

Important Considerations:

  • Supereruptions are rare events. Most volcanic systems that experience them do not have multiple occurrences. (Source: USGS)
  • Even if Yellowstone erupts again, it may be a smaller, non-explosive event. The most recent eruption 70,000 years ago was a lava flow. (Source: USGS)
  • Continued monitoring of Yellowstone is crucial. Seismographs and GPS help scientists understand stress changes in the Earth's crust, which could trigger earthquakes and influence volcanic activity. (Source: USGS)

Quotes:

  • "When we used magnetotellurics, we were able to see, actually, there’s not a lot there… There are these segregated regions where magma is stored across Yellowstone, instead of having one sort of large reservoir." - Ninfa Bennington, lead author of the study (Source: Fox Weather)
  • "Nowhere in Yellowstone do we have regions that are capable of eruption. It has a lot of magma, but the magma is not connected enough." - Ninfa Bennington (Source: The Washington Post)
  • "By no means is Yellowstone 'due for an eruption.' There will be eruptions, but it will probably be thousands of years before we can expect an eruption." - Erik Klemetti Gonzalez, associate professor of earth and planetary sciences (Source: The Washington Post)

Conclusion:

Recent research provides a more nuanced understanding of Yellowstone's volcanic system. While the potential for future eruptions remains, the current scientific consensus suggests that such events are unlikely in the near term. Continued monitoring and research are essential to further refine our understanding of Yellowstone's volcanic activity and its potential impacts.

Engineered for Hurricanes: The “Three Little Pigs” Were Almost Right

Engineered for Hurricanes: The “Three Little Pigs” Were Almost Right

Meteorology Matters examines the impact of hurricanes and extreme weather on residential buildings. Many Europeans believe their older buildings are stronger than American’s when in reality they’re not engineered to handle extremes, while survivorship bias may play a role in their perception. While many think the “Three Little Pigs” are the end all and be all of tough building examples, engineering plays a vital role in how those materials actually perform. Wood can actually perform better than concrete if it’s engineered better than brick for example. We analyze different building materials and construction techniques, exploring their resistance to high winds, storm surge, and flooding. Then dive into the importance of strong connections between building components, such as roofs and walls, and explore vulnerabilities in different types of construction, such as wood-framed homes. Highlighting the importance of understanding regional wind vulnerabilities and using building codes and design practices that meet local needs, research emphasizes the need to address the growing problem of residential building failures due to extreme weather events, particularly in areas prone to hurricanes and tornadoes.

NO, Hurricane Milton and Hurricane Helene were NOT Products of Weather Control but were Influenced by Climate Change

NO, Hurricane Milton and Hurricane Helene were NOT Products of Weather Control but were Influenced by Climate Change

We debunk the claim that Hurricanes Helene and Milton were artificially engineered or manipulated by the government, HAARP, or other individuals or groups. Experts in meteorology, geoengineering, and atmospheric research confirm that the technology needed to control or create hurricanes does not exist. They attribute the intensity of these storms to natural processes, emphasizing the role of climate change in intensifying hurricanes. We further expose the spread of misinformation online, particularly among right-wing influencers and accounts, highlighting the potential dangers of these unfounded theories. They underscore the importance of critical thinking and reliance on credible scientific sources in the face of such misinformation. While climate change may be influencing hurricanes in some ways, most notably by rapid intensification, these conspiracy theories lack real evidence and have no basis in science.

Tampa Soap Opera: Hurricane Evacuation Defier “Lieutenant Dan” Arrested After Surviving Helene and Milton on Boat

Joseph Malinowski, is the Florida man who went viral for his decision to ride out Hurricanes Helene and Milton on his small sailboat. He was dubbed "Lieutenant Dan" after the character in Forrest Gump because he was missing a leg among other similarities with the movie character and garnered considerable attention online. While he initially received support and even donations, Malinowski was eventually arrested for trespassing and failing to appear in court. We detail his legal troubles, as well as the concerns of his daughter who fears the attention will negatively impact her father.

Florida Homeowners Sell Due to Hurricanes, Flooding and Out of Control Costs

Florida Homeowners Sell Due to Hurricanes, Flooding and Out of Control Costs

Florida is facing a number of issues related to the insurance market and hurricanes. Insurance premiums are at an all-time high, with many homeowners facing an increase of up to 400%. The recent hurricanes, Helene and Milton, have caused billions of dollars in damage, further straining the insurance market. Some insurers are raising rates, while others are pulling out of the state entirely, leading to a shortage of insurance options. This is leading some homeowners to sell their properties at a loss, while others are hesitant to buy homes in Florida due to the risk of hurricanes. Despite the challenges, some residents are choosing to stay in Florida, citing the benefits of the state's weather, attractions, and overall lifestyle as outweighing the risks of hurricanes. There is also a growing interest in building hurricane-resistant homes, particularly domed structures, which have been proven to withstand even category 5 hurricanes. However, the high cost of building these homes presents a significant barrier for many.
