Executive overview
A filtered command-center view of earthquake occurrence, severity, depth, impact, and energy release.
Monthly event trend
Filtered events by month.
Magnitude class mix
Share of M5, M6, M7, and M8+ events.
Impact by depth class
Average impact reveals shallow-event exposure.
Top risk countries / regions
Composite of frequency, average magnitude, and average impact.
Real latitude/longitude map
Published world country geometry is drawn underneath the earthquake epicenters. Every point uses the dataset longitude and latitude.
Epicenter map
Color = magnitude, size = impact score. Hover any point for event details.
Occurrence patterns
Frequency by year, season, hour, weekday, and rolling rate.
Events by year
Seasonality by month
Events by UTC hour
Events by weekday
90-day rolling monthly rate
Smoothed count expressed as events per 30 days.
Magnitude and depth
Magnitude distribution, Gutenberg-Richter fit, depth classes, and magnitude-depth relationship.
