Guided trials

Examples to get started

Change one variable at a time and observe the effect.

Tokyo: frequent activity

Use 35.6762, 139.6503, 100 km, M4.5+ and 25 years. Then reduce the radius.

Use −0.1807, −78.4678. Compare M4+ and M5+ with the same period.

Use 37.8846, −4.7794. Broaden the radius before interpreting a low observed frequency.

Search M6+ over ten years and find the busiest months. Aftershocks mean events are not always independent.
