Weekly seismic activity briefing in Notion

Every Monday at 09:00 local time, generate a weekly seismic activity briefing and publish it as a new page in Notion so my team has a narrative record of the week's notable earthquakes.

Trigger: a cron schedule that fires once a week, Monday at 09:00 in my local time zone. Make the weekday, time, and time zone easy to change.

Data gathering from the USGS Earthquake service:

1. Call Query Earthquakes for the past 7 days with minmagnitude = 4.5 to get the headline events. Use format = geojson and an explicit starttime and endtime so the window is exact.

2. Call Query Earthquakes a second time for the same 7-day window filtered to alertlevel = orange and alertlevel = red (regardless of magnitude) so PAGER-tagged impact events are always captured, even if they were below 4.5.

3. Call Count Earthquakes twice at minmagnitude = 2.5: once for the past 7 days and once for the prior 7 days. Use these counts for the week-over-week comparison. The common docs explicitly recommend Count Earthquakes over re-running the full catalog query for totals.

Synthesis: write an analyst-style briefing, not a raw event dump. Prioritize, group, and explain. The brief should have these sections:

- Top 5 events of the week. Rank by a blend of magnitude and PAGER alert level. For each event include magnitude (with magnitude type), place, depth in km, PAGER alert color, tsunami flag, and the USGS event detail URL.

- Regions with elevated activity. Group the 4.5+ events by FE region or country and call out clusters or aftershock sequences in plain language.

- PAGER orange and red events. For any event with alert = orange or red, summarize the population exposure and impact context (PAGER ordering is green, yellow, orange, red ascending).

- Week-over-week comparison. Compare the M2.5+ count for the past 7 days to the prior 7 days as both a raw number and a percent change, and add a one-line interpretation.

Publish to Notion:

1. Call Create a Page under a configured parent (page or database) with the title formatted as "Seismic Weekly: {Mon DD} to {Mon DD}" using the window's start and end dates.

2. Call Append Block Children to populate the page with: an H2 for each section above, bulleted lists for the event details, and a callout block at the top with the quick stats (total M4.5+ count, total M2.5+ count, orange/red event count, week-over-week delta).

Notes on quality:

- Treat USGS timestamps as Unix milliseconds and render them in my local time zone in the brief.

- If a week is quiet (no M4.5+ events), still publish the page. State that explicitly, include the M2.5+ context count, and surface any orange/red PAGER events anyway.

- The Notion connection only sees pages that have been explicitly shared with it, so the destination page or database must be shared with the General Input connection.

- Keep the tone analyst-like: prioritize, interpret, and provide context. Do not paste raw JSON.
