Assessment

Why?

Strongest counted support: The primary study reports the roughness finding and its scale. weight 1.800000 evidence

Suppressed as dependent: The quoted passage directly concludes roughness at scales up to 10 km lacks primary control over maximum earthquake potential.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

Qualifications

• The analysis covered 15 globally distributed subduction zones and used a proxy for maximum earthquake magnitude.

  From Maximum earthquake magnitude unlikely to be controlled by subduction interface roughness Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  Specifies global subduction-zone scope and the earthquake-potential proxy.

• The dataset comprised 35 seismic-reflection profiles across 15 subduction margins.

  From Maximum earthquake magnitude unlikely to be controlled by subduction interface roughness Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  Adds profile and margin denominators.

• Maximum earthquake size was determined from the USGS catalogue within the study area.

  From Maximum earthquake magnitude unlikely to be controlled by subduction interface roughness Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  Clarifies the operational earthquake-size measure.

• The authors describe the sample as current best available but call for more 3D observations before broader linkage claims.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.
