  A 7.7 magnitude earthquake struck Southeast Asia, specifically the Myanmar-Thailand border region, on September 24, 2024. Initial reports indicated shaking felt across a wide area, including Bangkok, Thailand. The earthquake's depth was relatively shallow, raising concerns about potential damage. Specific details about the impact were still emerging at the time of the report.

  On the afternoon of March 24th, 2012, a significant seismic event, specifically a powerful earthquake measuring a substantial 7.7 on the moment magnitude scale, jolted the Southeast Asian region. The epicenter of this terrestrial tremor was located within the geographical boundaries of Myanmar (also known as Burma), with its effects radiating outward and impacting neighboring Thailand. Initial reports from the United States Geological Survey (USGS) pinpointed the quake's origin approximately 265 kilometers (or roughly 165 miles) north of the city of Chiang Mai, Thailand, and at a depth of approximately 84 kilometers (52 miles) beneath the Earth's surface. This substantial depth likely mitigated the surface-level damage, although the magnitude of the quake was such that it was widely felt across a vast expanse, including regions of Laos, Vietnam, and parts of China. The shaking prompted concerns about potential structural damage and the possibility of ensuing tsunamis, though initial assessments suggested the risk of a widespread, devastating tsunami was low due to the inland, rather than undersea, nature of the earthquake's origin. The event spurred immediate responses from international monitoring agencies and regional authorities who commenced efforts to assess the full extent of the impact, including casualties, infrastructural damage, and the need for emergency assistance in affected communities.

  HN commenters discuss the earthquake's impact, focusing on the lack of widespread information due to Myanmar's political situation and limited internet access. Some express concern about the potential for significant damage and casualties in Myanmar, given the country's vulnerability and the difficulty in getting aid. Others mention feeling the tremor in Bangkok, Thailand, and the general rarity of noticeable earthquakes in the region. Several commenters share resources for tracking earthquake activity and discuss the geological context of the event. The lack of immediate reports from inside Myanmar is highlighted as a major source of worry.

  The Hacker News post titled "7.7 magnitude earthquake hits Southeast Asia, affecting Myanmar and Thailand" has a modest number of comments, primarily focused on the surprising lack of widespread damage and casualties given the earthquake's significant magnitude.

  Several commenters discuss the apparent effectiveness of earthquake-resistant building codes and practices in Thailand, speculating that this contributed to the relatively low impact. One commenter highlights the role of building materials, noting that lighter materials like wood and bamboo, commonly used in the affected region, can perform better in earthquakes than heavier concrete structures, particularly those not built to code. This observation sparks a small discussion about the trade-offs between different building materials and their suitability in earthquake-prone areas.

  Another commenter questions the initial magnitude estimate of 7.7, pointing to subsequent revisions by the USGS that downgraded the earthquake to a 7.0. This raises the point that preliminary magnitude estimations can be subject to change as more data becomes available. The discussion around this highlights the complexities of accurately measuring earthquake magnitudes in real-time.

  One commenter shares a personal anecdote about experiencing a similar-sized earthquake in San Francisco and contrasts the relatively minor damage in Thailand with the potential for more significant damage in a densely populated urban area like San Francisco. This emphasizes the role of population density and infrastructure vulnerability in determining the overall impact of an earthquake.

  Finally, a few commenters express relief at the limited damage and casualties reported, acknowledging the potential for a much more devastating outcome. One commenter mentions the 2004 Indian Ocean earthquake and tsunami as a sobering reminder of the destructive power of large seismic events in the region.

  Overall, the comment section reflects a combination of surprise at the low casualty count, cautious optimism about the effectiveness of building practices, and a recognition of the inherent uncertainties and potential dangers associated with large earthquakes. The discussion remains factual and avoids speculation beyond the observations about building materials and the revised magnitude.

• Man's brain turned to glass by hot Vesuvius ash cloud

  Analysis of a victim's remains from Herculaneum, a town destroyed by the Vesuvius eruption in 79 AD, revealed that the extreme heat of the pyroclastic flow vitrified the victim's brain tissue, turning it into a glassy substance. This is the first time this phenomenon has been observed in archaeological remains. The victim, believed to be a man in his 20s, was found lying face down on a wooden bed, likely killed instantly by the intense heat. The glassy material found in his skull, analyzed to be mostly fatty acids and human brain proteins, provides unique insight into the extreme temperatures reached during the eruption and their effects on human tissue.

  In a macabre yet scientifically fascinating discovery, researchers studying the remnants of the catastrophic eruption of Mount Vesuvius in 79 AD have unearthed evidence of an unprecedented phenomenon: vitrification of brain tissue. The eruption, infamous for burying the Roman cities of Pompeii and Herculaneum under volcanic ash and pyroclastic flows, claimed thousands of lives. This latest finding, originating from the archaeological site of Herculaneum and detailed in the New England Journal of Medicine, focuses on the remains of a young man, believed to be in his mid-twenties, discovered in the 1960s within the Collegium Augustalium, a building dedicated to the imperial cult.

  While previous studies have identified skeletal remains and even partially preserved soft tissues at Herculaneum, this particular case presents a truly exceptional occurrence. The intense heat generated by the pyroclastic surge, a rapidly moving current of hot gas and volcanic debris, is postulated to have caused the victim's brain tissue to undergo vitrification, a process where organic material is transformed into a glassy substance. This process, akin to the formation of obsidian from molten rock, is exceptionally rare in archaeological contexts. The presence of glassy material within the victim's skull, identified through microscopic analysis and confirmed to contain proteins and fatty acids characteristic of brain tissue, provides compelling evidence for this extraordinary transformation.

  The researchers hypothesize that the extreme heat, estimated to have reached temperatures as high as 520 degrees Celsius, rapidly vaporized the victim's bodily fluids, creating an oxygen-deprived environment within the skull. This anoxic environment, combined with the intense heat, facilitated the vitrification process, essentially preserving the brain tissue in a glassy state for centuries. The preservation of such delicate organic material within the context of such a violent and destructive event provides invaluable insights into the extreme conditions experienced by the inhabitants of Herculaneum during the eruption and highlights the unique preservational properties of pyroclastic flows. Furthermore, the discovery sheds light on the destructive power of volcanic eruptions and contributes significantly to our understanding of the taphonomic processes involved in the preservation of human remains in such catastrophic events. This unprecedented find underscores the continuing potential for archaeological discoveries to enhance our comprehension of the past, even in sites that have been extensively studied for centuries.
