Choices about which artists you see in our galleries, choices about what relevant facts we share about the works, and choices about what - out of an infinite number of options - we don\u2019t say about them.\n \nPieces in this exhibition were made at a time when the world came to be shaped by the ideologies of colonial expansion and Western domination. And yet, that history and the stories of those marginalized do not readily appear in the still lives and portraits on display here. By grappling with what is visible and what remains hidden, we are forced to examine whose stories and histories are prioritized and why.\u00a0\u00a0\n \nIn this online exhibition, you can explore our efforts to deeply question the Museum\u2019s collection and our own past complicity in favoring colonial voices. In the Museum gallery, which will open in early 2021, you\u2019ll be able to experience the changes we\u2019re making to the physical space to highlight a more honest version of European and American history.\u00a0\n \nBy challenging our own practice, and continuing to add to what we know and what we write about the works we display, UMMA tells a more complex and more complete story of this nation - one that unsettles, and fails to settle for, simple narratives.\u00a0\n \n\u201cInvisible things are not necessarily \u2018not there\u2019....

It relies heavily on the availability and quality of data from a wide range of sources. Distributed Acoustic Sensing (DAS) is an emerging technology with the potential to greatly expand seismic data coverage by converting fiber-optic cables into dense arrays of seismic sensors. Compared to conventional instruments, DAS offers unique advantages in spatial density and convenient deployment, particularly in challenging or previously inaccessible environments. However, DAS also presents several limitations, including lower signal-to-noise ratios for individual channels, indirect measurements of ground motion, and directional sensitivity to axial fiber orientation. As a result, data processing procedures for routine seismic monitoring need to accommodate these features. This thesis contributes to developing modified processing techniques and evaluating the performance of DAS arrays under various conditions across three key applications: event detection, source imaging, and shallow subsurface characterization. The findings of these case studies aim to provide implications to the seismological community in assessing the potential for integrating DAS into modern seismic networks.\r\n\r\nIn Chapter 2, we focused on assessing the recording capability of an Ocean-Bottom DAS (OBDAS) array in the Sanriku region, Japan. We introduced two array-based detection methods\u2014Waveform Similarity Search (WSS) and Spectrum Similarity Search (SSS)\u2014that utilize the dense spatial sampling of OBDAS to detect coherent earthquake signals over subsections of the array. These techniques detected thousands of cataloged and previously uncataloged earthquakes. By analyzing the detection statistics, We found that the recording capability of the OBDAS array varies substantially across channels, and the array is well capable of recording regional earthquakes within a 100 km radius region. The array also recorded local repeating earthquakes across different subregions. These results highlight the feasibility of using OBDAS for long-term seismic monitoring and its potential to address the scarcity of offshore instrumentation, especially near subduction zones with extensive submarine fiber networks.\r\n\r\nIn Chapter 3, we investigated the potential of DAS on earthquake rupture imaging. We utilized both synthetic data and realistic recordings to identify the significant challenges of applying the Back-projection method (BP) to DAS data: the unstable solvability caused by highly asymmetric array geometry and limited azimuth coverage. Considering these constraints, we also proposed several data processing procedures to better adapt DAS data for BP analysis. We demonstrated the effectiveness of BP with the 2022 MW7.6 Michoac\u00e1n earthquake recorded by a DAS array in Mexico City. Our analysis demonstrated that, despite some limitations, DAS-based BP could successfully capture key rupture features, including multiple subevents and rupture direction. Meanwhile, we analyzed several sources of uncertainty and proposed practical guidelines for improving DAS-based BP performance. We also proposed an initial assessment scheme to understand the feasibility of BP analysis for a given event-array geometry, which is transferrable to other similar studies. Our work highlights the potential of DAS to enhance earthquake source imaging on a regional-to-local scale, offering alternative yet valuable insights into regions under-served by conventional seismic networks.\r\n\r\nIn Chapter 4, we used ambient seismic fields recorded by an ocean-bottom DAS array to image the shallow subsurface beneath the Florence region. Leveraging the long-duration recordings of DAS, we retrieved coherent surface waves through extensive stacking and applied a double-beamforming (DBF) approach to stably measure multimode dispersions. We performed a perturbational-based inversion method to invert for S-wave velocities over the first 2000-meter sediments underlying the fiber-optic cable. Our results demonstrate the effectiveness of the DBF method in enhancing spatial resolution. While the high cost and limited availability of underwater instruments hinder progress in imaging shallow structures in marine settings, this work demonstrates the potential of OBDAS arrays for high-resolution passive imaging.", "occurrence_notes":null, "guid":"135139-21876354@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/135139", "building_id":"1000188", "building_name":"1100 North University Building", "campus_maps_id":"628", "room":"2540", "location_name":"1100 North University Building", "has_livestream":0, "cost":"", "tags":["Dissertation"], "website":"", "sponsors":[ { "group_name":"Earth and Environmental Sciences", "group_id":"3170", "website":"http:\/\/www.lsa.umich.edu\/earth" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/04\/event_135139_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/04\/event_135139_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21876354 } , "134823-21875310": { "datetime_modified":"20250425T102012", "datetime_start":"20250425T103000", "datetime_end":"20250425T120000", "has_end_time":1, "date_start":"2025-04-25", "date_end":"2025-04-25", "time_start":"10:30:00", "time_end":"12:00:00", "time_zone":"America\/Detroit", "event_title":"Poetry and Poetics Workshop End of Year Celebration", "occurrence_title":"Reading Tracie Morris Together: \u201cThe Mrs Gets Her Ass Kicked\u201d", "combined_title":"Poetry and Poetics Workshop End of Year Celebration: Reading Tracie Morris Together: \u201cThe Mrs Gets Her Ass Kicked\u201d", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Reading Tracie Morris Together:\u201cThe Mrs Gets Her Ass Kicked\u201dFriday, April 25, 202510:30-12pmConversation and Celebration3222 Angell Hall\nWhat does it mean to \u201cread\u201d a sound poem together?
