On the morning of August 26, a glacial collapse brought on catastrophic flooding and mudslides on the China-Nepal border, destroying a port and border crossing in Gyirong County in Shigatse, Tibet, and inundating communities on each side of the border. Nepalese authorities have confirmed 1,050 deaths, with practically 4,000 individuals nonetheless lacking. Chinese language state media reported as of September 2 that 16 individuals have been killed in Tibet, with over 546 nonetheless lacking, roughly half of them international nationals. Search and rescue efforts are ongoing.
Along with highlighting the growing dangers of local weather change to Himalayan communities, the collapse and flooding have additionally drawn consideration to Chinese language authorities’ unrelenting efforts to clamp down on and management the tone of data within the wake of pure disasters. Chinese language and abroad netizens alike have famous the stark asymmetry between the common updates and open info sharing from Nepalese authorities, and the tight press controls, restricted info sharing, and lack of first-person survivor accounts on the Chinese language aspect. Latest reviews that ten individuals in Tibet have been punished for “spreading rumors” on-line concerning the flooding solely serve to strengthen these observations.
CDT Chinese language editors have been monitoring on-line censorship of video and pictures of the flooding, in addition to search censorship on varied platforms and muting of Weibo subjects associated to the flooding, dying toll, variety of lacking, and different disaster-related info. Their observations intently match the well-established playbook for dealing with of accidents and disasters, during which narratives are aggressively steered towards "constructive power" about government-led reduction efforts and away from impartial accounts or scrutiny of human components. Translated under is a CDT abstract of on-line info controls tracked and noticed within the days after the catastrophe:
CDT Editor’s Be aware: On the morning of August 26, 2026, a catastrophic mudslide struck Gyirong County in Shigatse, Tibet, destroying the principle constructing of Gyirong Port [a major border crossing between Nepal and Tibet]. Chinese language officers subsequently attributed the trigger to a flood triggered by a high-elevation glacial collapse upstream. As of 1:00 a.m. on August 29, Chinese language official reviews put the toll at 7 useless and 554 lacking in Tibet; an earlier report had damaged this determine down to incorporate 260 international nationals.
Within the aftermath of the flooding, quite a few clips of surveillance footage unfold throughout the Chinese language web, exhibiting the mudslide swallowing heavy vans, automobiles reversing to flee, half a freeway sheared away, and aerial panoramas of the scene. Two clips specifically—surveillance footage recording the second Gyirong Port’s border gate was swept away—have been restricted on home social-media platforms.
1. The Footage That Was Singled Out
Each clips look like from fastened surveillance cameras, exhibiting the port’s freight car parking zone and customs-and-border inspection space. A roiling flood surges down from the gorge above, water and dirt sweeping away the multi-story customs constructing and inundating every part in sight.
The movies have been first revealed by way of abroad channels such because the X account "Instructor Li Is Not Your Instructor." Web customers tried repeatedly to ahead these two clips by way of WeChat, with out success. In the meantime, surveillance footage of the identical catastrophe from different angles, filmed throughout the identical window of time, circulated broadly on WeChat, Weibo, Douyin, and Xiaohongshu (RedNote). A substantial share of this content material was picked up and reposted in varied codecs by mainstream Chinese language media accounts.
The disparity in censorship of video content material appears to be occurring on the stage of the pictures themselves, relatively than the accompanying textual content. The platforms clearly aren’t utilizing key phrase filtering to dam these movies. No matter censorship technique is getting used—video fingerprinting, body hashing, or model-based recognition of specific scenes—the result’s that particular movies are being positioned on a blocklist. We haven’t but been capable of decide whether or not this outcomes from the dichotomy between home WeChat and the abroad model of the WeChat app, or from another know-how geared toward figuring out these two specific movies.
The enlargement of censorship from phrases to pictures is a pattern CDT has documented with growing frequency in recent times, in the midst of our ongoing work monitoring sensitive-word lists.
2. “Sanitized” Search Outcomes on Xiaohongshu (RedNote)
As of August 28, CDT editors discovered that trying to find "Tibet mudslide" on the social-media platform Xiaohongshu (RedNote) returned the next prime video outcomes:
- "Dwell Footage! Gyirong County, Tibet Suffers Mudslide Catastrophe, Leading to Giant Numbers of Casualties and Lacking Individuals" (CCTV.com)

3. Weibo’s “Trending Subjects Checklist” Exhibits Solely Content material From Verified Accounts
Based mostly on repeated monitoring from August 27-28, Weibo’s trending subjects record noticed 714 situations of subjects associated to the Gyirong catastrophe falling off the record; of those, 306 subjects disappeared abruptly. Among the many 12 subjects we selected for extra in-depth analysis and cross-checking, a number of Gyirong-related subtopics displayed the identical sample: solely posts from verified Weibo accounts (“blue V” accounts) remained seen on the subject web page, whereas unusual customers’ content material didn’t seem within the outcomes in any respect. The next are a few of these subtopics, with their preliminary place on the record, period of time spent on the record, and their “warmth rating,” which is Weibo’s proprietary, algorithmically computed recognition rating for every hot-search entry.
"Tibet mudslide: 3 useless, 558 lacking" at one level occupied the #1 spot on Weibo’s trending subjects record. It remained on the record for 20.1 hours, and had a warmth rating of 704,000.
"Tibet mudslide: 265 lacking, 3 useless" likewise occupied the #1 spot on the record, the place it remained for 10.9 hours, with a warmth rating of 1.35 million.
"Gyirong, Tibet mudslide: 260 international nationals lacking" and "Extra collapses hit the slope above the landslide dam at Gyirong Port." Each of those subjects disappeared from the trending subjects record in lower than an hour.
"PLA and Folks’s Armed Police deploy over 500 rescue personnel" as soon as ranked #3, with a warmth rating of 1.79 million, and remained on the record for 2 hours.
"Port police continued directing evacuation whilst crowds fled" likewise stayed on the record for below an hour.
Please observe that regardless of search outcomes being "solely from verified accounts," that is an editorial statement on our half. At current, it can’t be taken as definitive proof of censorship or smooth censorship; we’re together with it for readers’ and researchers’ reference solely.
The next is a listing of photos and information concerning the catastrophe that continues to be seen on Chinese language home on-line platforms:
- CCTV’s before-and-after comparability photos of the Gyirong catastrophe zone
- Earlier than-and-after comparisons of Gyirong Port
- Excessive-definition footage of the mudslide catastrophe zone relayed by a Wing Loong drone
- Footage of a drone transporting firefighters
- Footage of Folks’s Armed Police troopers clearing roads
- Hearth and rescue groups arriving on the core catastrophe zone
- Port employees shifting in opposition to the gang to evacuate individuals in the course of the catastrophe
- Police persevering with to direct evacuation whilst crowds fled
- Information that 30,000 packages of reduction provides have been despatched to help Tibet’s catastrophe reduction
- Information that Apple would donate to Tibet
- Information that Premier Li Qiang arrived in Gyirong to direct emergency rescue efforts
4. A Brief-Lived Clue
At 3:00 p.m. on August 27, a subject briefly appeared on the trending record — "Gyirong Port solely reopened to cross-border site visitors six months in the past," with a warmth rating of 347,000 — earlier than disappearing.
The next sequence of dates explains the backstory: on July 8, 2025, Gyirong Port suspended cross-border operations resulting from a catastrophic flash flood. It resumed operations on January 1, 2026, on which day it processed 425 person-crossings and 64 vehicle-crossings. On August 26, 2026, it was destroyed once more by flooding and mudslides. In different phrases, inside fourteen months, the identical border crossing was reduce off twice by flash flooding and mudslides.
Equally short-lived have been the subjects "Investigating the recurrence of geological disasters close to Gyirong Port" (warmth rating 230,000, remained on the record for just one hour) and "Vacationers say Gyirong Port was once busy and bustling" (warmth rating 469,000, and solely remained on the record for below an hour).
From this, we are able to see that questions on web site choice, border infrastructure, glacial-lake and ice-collapse monitoring, and early-warning methods didn’t maintain any ongoing dialogue on the most important Chinese language-language trending-topics record.
5. The Trajectory of the Numbers
We additionally tracked the trajectory of formally reported numbers of the lacking and the useless.
At 11:00 p.m. on August 26, the official figures from the Chinese language aspect have been 265 lacking and three useless. By the morning of August 27, this had modified to a few useless and 558 lacking (together with 260 international nationals), a determine that “held regular” for roughly 36 hours. At 5:00 p.m. on August 28, it was up to date to 5 useless and 558 lacking. At 1:00 a.m. on August 29, per the newest report from Xinhua, two residents of Rexuo Village had been rescued, and there have been seven useless and 554 nonetheless lacking.
Inside that very same window of time, reviews from the Nepalese aspect of the border, as relayed on Weibo, climbed steadily from 157 useless, to 270, to 289, to 359. As of 6:00 a.m. on August 29, per the newest knowledge from Nepali police, the dying toll had risen to 616.
We imagine this appears to be like much less like a mass takedown marketing campaign, and extra like a finely calibrated operation: one during which public-opinion steerage is completed by means of a saturated info setting, relatively than by means of wholesale submit deletion. [Chinese]
