Two key questions are how relevant is this exacerbation and whether tsunami design parameters are significantly affected. We perform a non-stationary probabilistic tsunami hazard assessment (nPTHA) in the Southern California bays of San Pedro and San Diego, with consideration of tsunamis generated by earthquakes in the Alaska-Aleutians (<a href="https://kolektiva.social/tags/ASZ" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ASZ</span></a>) and Cascadia subduction zones (<a href="https://kolektiva.social/tags/CSZ" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CSZ</span></a>). We evaluate the changes of the maximum considered tsunami (<a href="https://kolektiva.social/tags/MCT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MCT</span></a>) design parameter, defined as a tsunami intensity that is exceeded with a 2% probability in 50 years. MCT elevation maps in the bays are calculated incorporating tides and SLR by means of a surrogate model. MCT elevations at assessed sites in San Pedro Bay and San Diego yield 2 m. The nPTHA shows that tsunamis generated in the ASZ zone are more hazardous in Southern California than those from the CSZ when evaluating MCT intensities. A comparison of scenarios with and without SLR also shows an increase of the MCT elevations of more than a foot in San Pedro Bay and San Diego, demonstrating that SLR causes a relevant impact, comparable to the influence of tides. The effect of SLR increasing MCT values is also comparable to the sensitivity of nPTHA results to some common earthquake epistemic uncertainties, such as the slip marginal distribution. Future tsunami hazard maps shall incorporate SLR when exposure times are long, as well as the uncertainty of tsunamigenic earthquake properties."<br> <br>Key Points</p><p> - Earthquakes in Alaska and Cascadia subduction zones produce tsunami hazards in Southern California that are exacerbated by sea level rise</p><p> - The elevation of maximum considered tsunamis (MCT) in San Pedro Bay and San Diego grow by more than a foot when SLR influence is included</p><p> - The impact of Alaskan earthquake epistemic uncertainties on MCT elevations in Southern California is similar to that of the sea level rise</p><p>Plain Language Summary</p><p>"Climate-change-driven sea level rise is expected to worsen tsunami hazards in the long term. Tsunami waves will be able to propagate over rising sea levels that will enable them to inundate higher land. In this study, we quantify the increase of tsunami hazards in Southern California due to sea level rise. We consider tsunamis originated in the Alaska and Cascadia subduction zones. Changes of tsunami design parameters, as a result of the sea level rise, are also analyzed. Namely, we analyze the changes of the 'maximum considered tsunami' (MCT) elevation, defined as the elevation exceeded with probability 2% in 50 years. We find that earthquakes of the Alaska Subduction Zone constitute the main <a href="https://kolektiva.social/tags/tsunamigenic" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tsunamigenic</span></a> contributor. We also find that sea level rise increases MCT tsunami elevations by 0.3 m. With this increase, MCT levels reach 2 m in San Pedro Bay and San Diego. We compare the impact of sea level rise exacerbating tsunami hazards with the impact of common uncertainty sources of tsunami hazard assessment models. The uncertainty of earthquake models, for example, can produce differences in MCT levels that are comparable to the SLR influence."</p><p>Source:<br><a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2024EF005435" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">agupubs.onlinelibrary.wiley.co</span><span class="invisible">m/doi/full/10.1029/2024EF005435</span></a></p><p><a href="https://kolektiva.social/tags/ClimateCrisis" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateCrisis</span></a> <a href="https://kolektiva.social/tags/ClimateCatastrophe" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateCatastrophe</span></a> <a href="https://kolektiva.social/tags/TsunamiRisks" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TsunamiRisks</span></a> <a href="https://kolektiva.social/tags/SeaLevelRise" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SeaLevelRise</span></a></p>

"As Adobe explores ways to evolve mobile photography, and in order to address some of these gaps, we have developed a camera app we call Project Indigo. Today, we are releasing this for iPhone as a free mobile app from Adobe Labs, available in the Apple App Store - to share our progress and get feedback from the community. The app offers full manual controls, a more natural ("SLR-like") look, and the highest image quality that computational photography can provide - in both JPEG and raw formats. It also introduces some new photographic experiences not available in other camera apps.

Let's break this down, starting with computational photography. While this phrase has come to mean many things, in the context of mobile cameras it typically includes two strategies: (1) under-expose slightly to reduce the clipping of highlights, and (2) capture multiple images in rapid succession when you press the shutter button. These images are aligned and combined to reduce noise in the shadows. The laws of physics say that imaging noise (the digital version of film grain) goes down as the square root of the number of images that are added together, so if the camera combines 9 images, noise is reduced by a factor of 3.
(...)
What's different about computational photography using Indigo? First, we under-expose more strongly than most cameras. Second, we capture, align, and combine more frames when producing each photo - up to 32 frames as in the example above. This means that our photos have fewer blown-out highlights and less noise in the shadows. Taking a photo with our app may require slightly more patience after pressing the shutter button than you're used to, but after a few seconds you'll be rewarded with a better picture.

As a side benefit of these two strategies, we need less spatial denoising (i.e. smoothing) than most camera apps. This means we preserve more natural textures."

US Treasury yields fell as safe-haven demand rose on Middle East tensions and potential US military involvement, while the Fed's upcoming SLR meeting further boosted long-end bonds; futures markets now price in a reduced likelihood of two rate cuts this year.

80mm on a #film #slr is one thing, but it becomes an actual telephoto on the #fujifilm #xt5 due to the crop sensor.

Over the years, I've developed a feel for what distance is best for a given lens to frame things like I want. Moving this lens from film to crop sensor, I really have to re-learn / rethink.. On film, this picture would have had the whole truck in the frame...

📢 User Modeling in Model-Driven Engineering: A Systematic Literature Review 📢

In this new paper, led by Aaron David Conrardy and with Alfredo Capozucca and yours truly, we study how users are modeled in current #modeldriven processes.

Modeling user's characteristics (including, e.g. their personality) could open the door to more #personalized applications.

But, unfortunately, we argue that:

❌ User modeling is mostly ignored or very superficial

❌ There is no unified user model that can be easily adopted

❌ Opportunities leveraging AI for user modeling (and viceversa) aren't there yet

Let's change this 💪 . Starting with a discussion in #Koblenz for #STAF #ECMFA!
