官方分析，说到了哪一步？What do the official analyses establish?

报告支持怎样的理解？

作者综合地震、卫星、无人机及其他记录，认为岩体失稳切下了上覆冰川的一部分，随后形成级联碎屑洪水，区别于传统冰湖溃决。报告引用 Hendrickx 初步模型，估计岩石与冰共同体积约 1.32 亿 m³，仍需高分辨率灾前、灾后数字高程模型验证（印刷页 12–13、21）。

印刷页 10 报告：Sentinel-1 InSAR 在 7 月 7 日至 8 月 24 日的 48 天内测得最高约 40 cm 视线向位移。它提供后续调查线索，不能直接读成 40 cm 的垂直下沉。

预警部分强调，应核对消息是否及时到达、能否被理解，以及人们能否采取行动；发出短信的数量本身不能证明预警有效。

What does the report support?

The authors combine seismic, satellite, drone and other evidence to interpret a bedrock failure that removed part of an overlying glacier and triggered a cascading debris flood, rather than a conventional GLOF. Citing Hendrickx's preliminary model, the report estimates about 132 million m³ of rock and ice combined, still requiring validation with high-resolution pre- and post-event elevation models (printed pages 12–13 and 21).

Printed page 10 reports up to about 40 cm of Sentinel-1 InSAR line-of-sight displacement over the 48 days from 7 July to 24 August. This is evidence to investigate, not a measurement of 40 cm vertical subsidence.

The warning assessment asks whether people received, understood and could act on alerts in time. The number of SMS messages sent alone does not establish warning effectiveness.

官方材料要点

USGS 初步分析认为，这次碎屑流与洪水可能由涉及冰川的快速坡体失稳触发，沿河谷传播约 100 公里。截至 8 月 28 日，尚不能区分是滑坡卷入冰川，还是冰川本体崩塌。

Agency findings, paraphrased

USGS provisionally links the debris flow and flood to rapid glacier-involving slope failure, travelling roughly 100 km. Its 28 August account does not resolve whether a landslide incorporated glacier ice or the glacier itself collapsed.

官方材料要点

Copernicus 以灾后卫星影像对部分河段开展灾损判读。本站接入四个产品的物质运动范围：夏布鲁贝西、提姆里、比杜尔与 Phosretar；它们只回答对应分区和日期的问题。

Agency findings, paraphrased

Copernicus interpreted post-event imagery in selected river sections. This site uses mass-movement polygons from four product versions for Syapru Besi, Timure, Bidur and Phosretar, each limited to its area and imagery dates.

官方材料要点

UNOSAT 对拉苏瓦与努瓦科特的泥流／岩屑流影响开展初步评估，使用 8 月 26 日 PlanetScope 与 27 日 Sentinel-2 影像。它提供的是分析区内的历史影像判读，不是全流域持续观测。

Agency findings, paraphrased

UNOSAT assessed mudflow and rockflow impacts in Rasuwa and Nuwakot using 26 August PlanetScope and 27 August Sentinel-2 imagery. It describes a historical interpretation within the analysed area, not continuous basin-wide monitoring.

官方材料要点

UNOSAT 从 8 月 28 日 CARTOSAT-3 影像判读两处新形成的堰塞水体，正文估计约 12 和 19 公顷，位于边境附近及潜在冰岩崩源区一带。

Agency findings, paraphrased

UNOSAT interpreted two newly formed barrier lakes in 28 August CARTOSAT-3 imagery, estimating about 12 and 19 hectares near the border and potential ice-rock avalanche source area.

官方材料要点

JAXA 用 8 月 28 日 ALOS-2 雷达资料生成自动洪水代理图，由 Sentinel Asia 发布，提供与光学影像不同的判读线索。

Agency product, paraphrased

JAXA produced an automatic flood proxy from 28 August ALOS-2 radar observations, published through Sentinel Asia. It offers a different line of evidence from optical imagery.
