Spatial Distribution
The spatial distribution shows the geographic pattern of earthquakes. You can now draw shapes directly on the map to filter earthquakes by area.

Depth Distribution
The depth distribution shows how earthquakes are distributed vertically in the Earth's crust and upper mantle, which can indicate different tectonic processes.
Gutenberg-Richter Relation
The Gutenberg-Richter relation shows the relationship between earthquake magnitude and frequency, typically expressed as log(N) = a - bM where N is the number of events ≥ magnitude M. The slope 'b' represents the relative abundance of large to small earthquakes.
Parameters
Magnitude of Completeness
The magnitude of completeness (Mc) is the lowest magnitude at which all earthquakes in a space-time volume are detected. This is essential for statistical analyses as incomplete data can lead to biased results.
Analysis Results
Temporal Analysis
This analysis shows how earthquake activity changes over time, including possible trends in frequency and magnitude.
Magnitude-Frequency Distribution
This histogram shows the distribution of earthquakes across different magnitude ranges, helping to visualize the frequency of different earthquake sizes.
