Ask the Pacific: A Better Way to Read the Ring of Fire

19 August, 2026

I like rocks, techtonic plates, and like to learn more about thinks that make them move

“The Ring of Fire” sounds like a neat circle around the Pacific. The real story is much more interesting—and much less tidy.

It is a huge, changing system of volcanoes, earthquakes, trenches, faults, island chains, and communities. There is no single line to follow, and a map full of red dots does not tell us where danger is or what will happen next.

That is why I built Restless Pacific: an interactive atlas for exploring the evidence behind the name. You can move from the map to historical records, compare volcanic and earthquake data, and see what tsunami records can—and cannot—tell us.

The heart of the project is Ask the Pacific, a conversational guide to the atlas. Ask a question in plain language and it helps you investigate the data, find relevant patterns, and understand the limits of the answer. It is meant to make the Pacific easier to explore, not to pretend that complex geology has simple explanations.

For example, you might ask:

• Where are the most active volcanic regions in the record?
• How do recent earthquakes line up with plate boundaries?
• What does the historical tsunami data leave out?

Ask the Pacific points to the relevant evidence and keeps the context attached. A cluster of observations may reflect activity, monitoring, reporting, or all three. Missing values do not necessarily mean zero. Nearby plate boundaries provide context, but they do not prove what caused a particular event.

The quiet engine underneath

The map is powered by PostgreSQL with PostGIS, an extension that gives a normal database a working understanding of geography. Instead of storing a volcano as only a name and a latitude, the project can store points, lines, and regions as spatial data.

That makes questions about place possible. PostGIS can find earthquakes within a chosen distance, count records inside a Pacific region, compare observations with plate boundaries, and group events into geographic grid cells. Spatial indexes make those searches practical even when the database contains many years of records.

The data arrives from sources including the Smithsonian Global Volcanism Program, USGS, and NOAA. It is cleaned and shaped in PostgreSQL, while the original source, date, location, and missing values remain visible in the analytical model. PostGIS then acts as the bridge between the raw record and the map: the database does the geographic work, and the interface turns the result into something people can explore.

The project combines that spatial database with a focused Data Lab powered by Metabase. The dashboards use read-only analytical views, so Ask the Pacific and the charts can work from a deliberate public data surface rather than an unrestricted database browser.

Restless Pacific is not a warning system, forecast, evacuation tool, or claim that the historical record is complete. It is an invitation to look more closely—to ask better questions, follow the sources, and keep uncertainty in view.
