In summer 2025, following the rapid retreat of South Sawyer Glacier, a large landslide sent rock careening into the fjord, altering the wider landscape in a matter of minutes.<\/p>\n<p>The slide culminated on the morning of August 10, 2025, when at least 64 million cubic meters of rock slid downslope. Material entering the fjord induced a tsunami that stripped trees and other vegetation from the opposing fjord wall up to 1,578 feet (481 meters) above sea level. While this peak was the highest \u201crunup\u201d reached by the tsunami, shores and islands down the fjord also saw substantial destruction.<\/p>\n<p>NASA-USGS Landsat satellites captured these images on July 26 (left) and August 19 (right), before and after the event, respectively. \u201cThe bright landslide scar on the north side of the fjord is striking, as is the \u2018bathtub\u2019 ring around the fjord showing the areas where the forest was leveled by the tsunami,\u201d said Dan Shugar, a geomorphologist at the University of Calgary.<\/p>\n<p>Note that Sawyer Island, about 6 miles (9 kilometers) from the landslide, also turned from green to brown. Only a few trees still stood at the island\u2019s higher elevations.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-wide\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm%E2%80%99s-post-tsunami-landscape\/tracyarm_landslide_pho_20250813.jpg?w=5900&#038;h=3884&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" rel=\"noopener\"><img decoding=\"async\" width=\"5900\" height=\"3884\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm%E2%80%99s-post-tsunami-landscape\/tracyarm_landslide_pho_20250813.jpg?w=5900&#038;h=3884&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"An aerial view shows a glacier ending in a fjord with small icebergs in the water.

Rainfall, which was moderate prior to the event, and the rapid retreat of glaciers can both destabilize a slope. What is clear, however, is that the glacier\u2019s retreat exposed a new area of open water, leaving it vulnerable to a landscape-reorganizing tsunami.\u00a0<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-wide\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm%E2%80%99s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=2160&#038;h=2070&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" rel=\"noopener\"><img decoding=\"async\" width=\"2160\" height=\"2070\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm%E2%80%99s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=2160&#038;h=2070&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"A satellite view shows Tracy Arm, centered, in context with other nearby waterways and glaciers in southeast Alaska.\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" loading=\"lazy\" srcset=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=2160&#038;h=2070&#038;fit=crop&#038;crop=faces%2Cfocalpoint 2160w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=300&#038;h=288&#038;fit=crop&#038;crop=faces%2Cfocalpoint 300w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=768&#038;h=736&#038;fit=crop&#038;crop=faces%2Cfocalpoint 768w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=1024&#038;h=981&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1024w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=1536&#038;h=1472&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1536w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=2048&#038;h=1963&#038;fit=crop&#038;crop=faces%2Cfocalpoint 2048w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=400&#038;h=383&#038;fit=crop&#038;crop=faces%2Cfocalpoint 400w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=600&#038;h=575&#038;fit=crop&#038;crop=faces%2Cfocalpoint 600w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=900&#038;h=863&#038;fit=crop&#038;crop=faces%2Cfocalpoint 900w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=1200&#038;h=1150&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1200w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/tracy-arm\u2019s-post-tsunami-landscape\/alaskatracyarm_oli2_20250819.jpg?w=2000&#038;h=1917&#038;fit=crop&#038;crop=faces%2Cfocalpoint 2000w\" sizes=\"auto, (max-width: 2160px) 100vw, 2160px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\">\n<div class=\"hds-caption-text p-sm margin-0\">Tracy Arm and other nearby fjords connect with Stephens Passage, a major waterway in southeast Alaska, visible in this image captured on August 19, 2025, by the <a href=\"https:\/\/science.nasa.gov\/mission\/landsat\/oli\/\" rel=\"noopener\">OLI<\/a> (Operational Land Imager) on <a href=\"https:\/\/science.nasa.gov\/mission\/landsat-9\/\" rel=\"noopener\">Landsat 9<\/a>.<\/div>\n<div class=\"hds-credits\">NASA Earth Observatory\/Michala Garrison<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\n<p>No one was injured in the event, though it did catch some by surprise.
