🚨Petra Alert🚨 Within the last hour, a 7.0-magnitude earthquake occurred in Northern California, approximately 30 miles off the coast of Eureka, CA. The National Weather Service (NWS) issues tsunami warnings for the United States through its Tsunami Warning Centers. In California, these warnings are disseminated by the California Governor's Office of Emergency Services (Cal OES) and local emergency management agencies. Alerts are broadcast via Wireless Emergency Alerts (WEA) to mobile devices, NOAA Weather Radio, and other public alert systems. In anticipation of any aftershocks, tremors, or additional earthquakes, we recommend hotels promptly evacuate guests and staff to locations at least 0.25 miles inland or 50 feet above sea level. If evacuation is not feasible, implement vertical evacuation by moving individuals to the upper floors of sturdy, reinforced buildings. Ensure that staff are trained to assist all guests, particularly those with mobility challenges, and communicate evacuation instructions clearly in multiple languages if necessary. Keep emergency kits accessible and remain in safe zones until authorities declare the area secure. Preparedness and swift action are crucial to ensuring safety and minimizing risks. Thank you and stay safe. https://lnkd.in/gjdq73NV

A catastrophic earthquake and tsunami are anticipated for the Pacific Northwest coast, stemming from the Cascadia Subduction Zone. This 700-mile fault, stretching from Northern California to Vancouver Island, could trigger a 9.0 magnitude earthquake similar to Japan's 2011 disaster. Recent research has revealed the fault is divided into several segments, each with unique geological properties, with the segment off Washington's coast posing the greatest risk. Despite the known dangers, infrastructure built before 2005 was not designed to withstand such an earthquake, and tsunami building codes were only implemented in 2016. The geological record indicates these mega earthquakes and tsunamis occur approximately every 500 years, with the next one expected within the next 200 years. The preparedness of the Pacific Northwest is inadequate, with many bridges, buildings, and critical facilities in vulnerable locations. Experts like Corina Allen from the Washington Geological Survey and Yumei Wang from Portland State University highlight the pressing need for retrofitting and building vertical evacuation structures. Currently, only three such structures exist in the region, with four more planned, though at least 50 are needed in Washington alone. Despite the potential for severe consequences, investment in necessary preparations is slow, hindered by the uncertain timing of the next event and the substantial costs involved. Seismologist Diego Melgar emphasizes that comprehensive preparations are a long-term effort that may not yield immediate benefits but are crucial for future generations. Ensuring safety involves building codes, early warning systems, and accessible evacuation zones, but achieving this requires significant financial and societal commitment . --- Sources: 1.

Northern California coast under tsunami warning after 7.0-magnitude earthquake BREAKING: Tsunami Warning Issued for Northern California Coast After Powerful Earthquake As we reported earlier, a powerful earthquake struck off the coast of Northern California, triggering a tsunami warning for communities along the coast. Now, we're going back to NBC News meteorologist Bill Karens, who has been tracking this developing story. Bill, can you tell us more about the earthquake and the tsunami warning? The Earthquake A magnitude 7.0 earthquake rocked the coast of Northern California today, with the epicenter located approximately 10 kilometers beneath the ocean surface, about 60-75 miles (6-12 kilometers) offshore. While damage from the shaking is expected to be significant in the immediate area, the impacts are expected to be limited given the relatively unpopulated region. The Tsunami Warning The tsunami warning has been issued for several areas, including Fort Brag, which received the alert 20 minutes ago. As of now, there have been no reports of devastating tsunamis or any significant damage. As we wait for updates, fears are gradually easing, but it's essential to remain prepared for any potential disruptions. Impacts and Preparations The tsunami warning also extends to Southern Oregon, with the waves expected to arrive in the San Francisco area around 1:10 pm local time. The coastline is relatively dense and wooded, with few coastal communities, which could limit the impact of a potential tsunami. Conclusion This powerful earthquake is a significant event, with only about 18 earthquakes of magnitude 7.0 or larger occurring annually worldwide. Fortunately, preliminary reports suggest that the tsunami warning may have minimal impacts, but it's essential to continue monitoring the situation closely. We'll keep you updated on any new developments.

High-resolution numerical modelling reveals tsunami risk hotspots in Xiamen City, China - Frontiers in Marine Science: Tsunamis, generated by submarine earthquakes, landslides, or volcanic eruptions, are a significant hazard to coastal areas owing to their sudden onset and rapid propagation speed. Thus, tsunami disaster risk assessment is crucial to determine potential losses and severity of future tsunami impacts, providing essential support for disaster prevention and mitigation efforts. This study presents a case study of Xiamen City in Fujian province for developing a high-precision tsunami model. Utilizing nearshore water depth and digital elevation model data, we established a high-resolution tsunami numerical simulation model for Xiamen City that accounts for the impact of water overrunning levees and overshoals. Historical tsunami disaster records were used to validate the numerical model. By determining multiple tsunami source scenarios that could potentially affect the counties of Xiamen City, we simulated the inundation range and water depth distribution required for the potential maximum tsunami event. The simulation results facilitated a tsunami hazard assessment. Considering land use and important tsunami-affected exposures including industrial and chemical enterprises and ports, we evaluated the vulnerability of Xiamen City to tsunami disasters. Based on the determination of hazard and vulnerability levels, we investigated the risk distribution of tsunami disasters in Xiamen City. The results of this study lay the groundwork for developing methodologies to improve tsunami disaster risk assessment in coastal areas. https://lnkd.in/edWX98bF

Japan just had a 7.1 magnitude earthquake, triggering a Tsunami warning. Japan and its surrounding areas account for 18% of earthquakes in the world. Japan and earthquakes go hand in hand due to the country's position along the Pacific Ring of Fire, and on the convergence of four major tectonic plates - the Pacific, Philippine, Eurasian, and North American plates. The Pacific Plate, in particular, is responsible for much of Japan's seismic unrest. As the world's largest tectonic plate, it is perpetually colliding and grinding against the smaller Eurasian and North American plates under the Japanese archipelago. Compounding this precarious tectonic positioning is Japan's mountainous terrain, which is the product of ancient seismic activity. The ongoing deformation and uplift of the Japanese landmass creates inherent structural instability that is routinely shaken by tremors and temblors. Tragically, Japan's long history of deadly quakes underscores the country's unenviable status as one of the world's most earthquake-prone regions. Yet remarkably, the Japanese people have cultivated a culture of earthquake preparedness that is the envy of the world. Rigorous building codes, advanced early warning systems, and community-based disaster planning have saved countless lives. Japan's resilience in the face of these natural calamities is a testament to the country's strength of spirit and unwavering determination.

It’s extremely concerning the reduction of Tsunami program funding in Alaska is even being considered! And that news came on March 27, 2024 - the day of the 60th anniversary of the 1964 earthquake that claimed the lives of over 130 people, 122 of which were fatalities caused by tsunami’s. As stated in the below article- The National Tsunami Hazard Mitigation Program (NTHMP) has provided Alaska with up to $700,000 a year and those funds are used to provide guidance to at-risk populations with tsunami hazard assessment, evacuation planning and public education - which includes tsunami inundation mapping, sirens, research and, critical public education that can SAVE LIVES!!! The Tsunami Workshop I recently presented at in Seward is one of those outreach and education events possible because of that NTHMP funding. What hazards does Alaska have that can cause tsunamis?? 🫨Earthquakes 🌋Volcanoes ⚠️Landslides 🌋The Augustine Volcano in Alaska (2006). In 1883, a debris flow from the collapse of the north face of the Augustine Volcano's peak caused a local tsunami. Damage to homes and fishing boats was reported. (Source: U.S. Geological Survey, Game McGimsey) 🫨⚠️According to Alaska Seismic Hazards Safety Commission. scientists have long recognized that Alaska has more earthquakes than any other region of the United States and is, in fact, one of the most seismically active areas of the world. ➡️Alaska is home of the the second largest earthquake ever recorded (1964 Great Alaska Earthquake, magnitude 9.2) ➡️Alaska has 11 percent of the world's recorded earthquakes ➡️Three of the eight largest earthquakes in the world were in Alaska ➡️Seven of the ten largest earthquakes in the United States were in Alaska. Since 1900, Alaska has had an average of: 🌊Six magnitude 6 to 7 earthquakes per year 🌊Forty five magnitude 5 to 6 earthquakes per year 🌊Three hundred twenty magnitude 4 to 5 earthquakes per year 🌊An average of a 1,000 earthquakes are located in Alaska each month. 🌊⚠️According to the Alaska Earthquake Center, coastal Alaska communities live with the most serious tsunami risk in the United States. Historically, tsunamis generated by earthquakes in Alaska have caused damage and loss of life along the West Coast and across the Pacific (Alaska Earthquake Center, 2022). Is saving $700,000 more important than providing tools, education, information, and resources to at risk coastal communities that can save lives? $700,000 is a drop in the bucket and a sound investment for a program that helps protect the lives of the people in our coastal communities by providing education and resources that help them be more resilient and better prepared for when the next tsunami hits. Cutting funding for the NTHMP program would be a grave mistake. The conversation SHOULD be how can we increase funding or fight to save what little funding we do have. 🙏🏽
