• Data: R’s built-in quakes dataset
• 1,000 seismic events near Fiji since 1964, all magnitude 4.0 or greater
• Variables: latitude, longitude, depth (km), magnitude (Richter) and number of reporting stations
• Goal: explore where the earthquakes happen, how deep they go and how strong they are, using interactive Plotly charts

Hover, zoom, rotate and click legend items on the following slides.

• Earthquakes trace a sloping subduction zone: they get deeper toward the west, visible in the 3D plot
• Depths are bimodal, with clusters of shallow and very deep events
• Stronger earthquakes are picked up by more stations, a near-linear relationship
• Plotly makes these patterns easy to explore interactively

Thank you!
