Dr. Eric J. Fielding, PhD<p>NASA Radar Imagery Reveals Details About Los Angeles-Area Landslides. Landslides on Palos Verdes peninsula have been moving rapidly in last two years. NASA airborne radar called UAVSAR flies on piloted NASA planes and measures displacements of the ground surface using InSAR analysis. We requested flights in three directions to map motion of landslides on the Palos Verdes peninsula next to Los Angeles. <a href="https://mastodon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NASA</span></a> <a href="https://mastodon.social/tags/NASA_JPL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NASA_JPL</span></a> <a href="https://mastodon.social/tags/InSAR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>InSAR</span></a> <a href="https://mastodon.social/tags/radar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>radar</span></a> <a href="https://mastodon.social/tags/landslides" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>landslides</span></a> </p><p><a href="https://www.jpl.nasa.gov/news/nasa-radar-imagery-reveals-details-about-los-angeles-area-landslides/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">jpl.nasa.gov/news/nasa-radar-i</span><span class="invisible">magery-reveals-details-about-los-angeles-area-landslides/</span></a></p>

偉吉<p>There was a Sentinel-1 scene capture some hours after the Vanuatu earthquake yesterday, so I went to create an interferogram using ASF's on-demand Vertex service from an image pair (2024-12-05 to 2024-12-17).

Jascha Polet<p>Interesting paper: using InSAR the authors found widespread subsidence of up to 8 cm along the coastal strip of the Miami barrier islands from 2016 to 2023, probably related to construction activities. The subsidence is likely due to prolonged creep deformation of sandy layers within the limestone.<br><a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024EA003852" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">agupubs.onlinelibrary.wiley.co</span><span class="invisible">m/doi/10.1029/2024EA003852</span></a></p><p><a href="https://mastodon.social/tags/geoscience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>geoscience</span></a> <a href="https://mastodon.social/tags/satellite" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>satellite</span></a> <a href="https://mastodon.social/tags/insar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>insar</span></a> <a href="https://mastodon.social/tags/subsidence" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>subsidence</span></a> <a href="https://mastodon.social/tags/florida" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>florida</span></a> <a href="https://mastodon.social/tags/coast" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>coast</span></a> <a href="https://mastodon.social/tags/construction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>construction</span></a></p>
