Use cases

What it unlocks

⌁

For an agent

A property-catastrophe risk agent ingests ADW-356 daily and gates model-run scheduling based on alert level: when score > 66 (WATCH-equivalent pressure for a single high-severity US volcano), the agent automatically queues an updated Oasis loss simulation for any insured properties within 100 km of the flagged volcanoes named in the Signal tier's elevated_volcano_names field. The methodology_version tag — tied directly to USGS HANS alert weights (WARNING=100, WATCH=66, ADVISORY=33) — lets the agent reference authoritative government thresholds rather than an internal heuristic, preserving audit chain for reinsurance treaty documentation.

📈

For the business

A specialty-lines underwriter covering hospitality and agricultural businesses in Pacific Northwest and Hawaii uses the daily ADW-356 refresh to make binding decisions with same-day awareness of eruption-risk escalations — something impossible with proprietary EMSI or Verisk volcanic datasets that update on event-driven, irregular schedules. When the index rises above its 50-baseline (equivalent to five mid-severity advisories simultaneously), the underwriter suspends new binding authority for at-risk ZIP codes and initiates policy-holder notification, replacing the current practice of monitoring USGS pages manually across eight separate volcano observatory feeds.

Forward outlook

Prediction

Horizon: —
Recommended use: Real-time US volcanic alert pressure index. Rising scores signal more or higher-severity volcanic unrest — relevant to aviation route risk, natural-hazard insurance exposure, and supply-chain disruption screening (ash plumes affect Pacific/Alaska air freight). Descriptive only — not an eruption-probability model.

Methodology

How it's built

alert-weight sum normalized to 5-volcano baseline (BASELINE_SUM=250)

Version ADW-356-live-1.0 · validated to beat a naive baseline · benchmark: No equivalent free real-time index; EMSI/Verisk volcanic datasets are proprietary
