Every event from 18 August 2020 to the latest update in 2026, mapped and charted by year, magnitude and depth.

Indonesia Earthquake Activity Analysis
An interactive Tableau Public dashboard of 13,023 earthquakes recorded in and around Indonesia from August 2020 to 2026. It shows where they happen, how activity changes from year to year, how strong and how deep they are, and the strongest events on record.

MEASURED EVIDENCE
What can be verified.
Metrics and outputs drawn from the project artifacts—not estimates added for presentation.
Events from magnitude 5.0 up, about one in ten of all recorded earthquakes.
The largest magnitude in the catalogue, top of the ten strongest events ranked on the second dashboard.
11,707 of the 13,023 events, which makes moderate earthquakes the bulk of recorded activity.
VALIDATION
The figures agree with each other: the yearly counts add up to the 13,023 total, the magnitude bands add up to the same total, and the bands from 5.0 upward add up to the 1,278 headline figure.
PLAIN-LANGUAGE INTERPRETATION
These are counts of recorded earthquakes, not a measure of risk to any place. Magnitude is shown as recorded in the catalogue.
Why this project matters
An earthquake catalogue is a long table of coordinates, magnitudes and depths. Read as a table, it’s hard to see where activity clusters, whether it’s rising or falling, or how often strong events happen. This dashboard turns that table into a few views a reader can take in at a glance.
What was developed
Two linked dashboards. The overview pairs five headline figures with an activity map coloured by magnitude and an annual trend line, all filtered by year. The second dashboard covers the magnitude distribution, the ten strongest events and a magnitude against depth scatter. Buttons move between the two.
What it means
Most recorded activity is moderate. Events between magnitude 4.0 and 4.9 make up about 90% of the catalogue, while 1,278 reached magnitude 5 or above and the strongest was 7.8. Across the full years 2021 to 2025, the catalogue recorded between 1,831 and 2,251 earthquakes a year.
04 / WHERE THIS WORK APPLIES
From project to practical use.
Briefing material for disaster preparedness and response teams, teaching regional seismic patterns, and a reusable layout for any event catalogue that has a location, a size and a date.
05 / LIMITATION
What the project does not solve yet.
It describes the catalogue; it doesn’t forecast earthquakes or measure risk. 2020 starts on 18 August and 2026 is a partial year, so those totals can’t be compared with full years. Only 38 events below magnitude 4.0 appear, which most likely reflects what the catalogue records rather than a lack of small earthquakes.
06 / NEXT ITERATION
Future advancement
Group aftershocks with their main shock, break activity down by depth class, and refresh the data automatically from the USGS feed.
