This visualization displays earthquake data from the USGS for the past week, with each earthquake’s position mapped using a geographic projection. Circle size encodes magnitude, and color encodes depth category (shallow, intermediate, or deep). Tectonic plate boundaries are overlaid in orange. Users can drag to pan the globe and scroll to zoom; clicking an earthquake opens its USGS detail page.

AI-generated description

Previous

  • use data from an API
  • circle size related to magnitude value
  • interaction: click circle and direct to a url

Now

  • added color to the circles, according to depth (shallow, intermediate, deep)
  • added interaction: zooming (using d3.zoom())
    • Problem: Panning does not work after zoom in
  • added interaction: dragging

Ver4 Earthquakes (past 30 days)

This visualization displays earthquakes from the past 30 days on an interactive world map, with circle size representing magnitude. Circle color encodes depth category: red for shallow (less than 70km), green for intermediate, and blue for deep (300km or more). Users can zoom and pan using d3.zoom(), and clicking any circle opens the corresponding USGS earthquake report. The map uses d3.geoEquirectangular and d3.geoPath to render countries from topojson data and tectonic plate boundaries, while earthquake data is fetched live from the USGS API.

Ver3 Earthquakes (past 30 days)

This visualization displays global earthquake activity from the past 30 days on an interactive world map. Circles are positioned using a D3 geoEquirectangular projection, with circle size encoding earthquake magnitude. Color encodes depth, with red for shallow (<70km), green for intermediate (70-300km), and blue for deep (≥300km) earthquakes. The map also shows country boundaries, graticules, and tectonic plate boundaries. Users can click any earthquake circle to open its USGS details page in a new tab, or pan and zoom using the d3.zoom() interaction. Additional brush-based zooming is implemented to allow for more intuitive exploration of the data.

Ver2 of Earthquakes (past 30 days)

This map shows the locations of earthquakes from the past 30 days, with each event drawn as a circle scaled by magnitude and colored by depth. The visualization uses real-time GeoJSON data from USGS.gov, and each earthquake marker is hyperlinked to its corresponding USGS event page. Built with D3.js, the map colors circles along a gradient to represent depth, with clickable markers that open detailed information for each recorded earthquake.

Fork of Fork of Fork of Earthquakes (past 30 days)

This map shows all earthquakes from the past 30 days, with point size encoding magnitude and color encoding depth category (red for shallow, green for intermediate, blue for deep). The visualization overlays tectonic plate boundaries in orange, drawn from a GeoJSON dataset, atop a world map rendered from TopoJSON. Earthquake data is fetched live from the USGS feed, with each quake rendered as a circle positioned by its longitude/latitude, sized by magnitude (proportional to 1.5^mag), and colored by depth (shallow <70km, intermediate 70–300km, deep ≥300km). Circles link to the USGS event page. The map uses an equirectangular projection with graticule and outline, combining three data sources: country boundaries, tectonic plate boundaries, and recent earthquake records.

earthquakes

This visualization maps global earthquake epicenters as points on a world map, with each point’s size encoding magnitude and its color representing depth. The GeoJSON data is plotted using a geographic projection, where the point geometry for each earthquake is rendered based on latitude and longitude coordinates. Magnitude values are mapped to graduated circle sizes, allowing quick comparison of seismic strength, while depth is encoded through a sequential color scale—typically from shallow (light) to deep (dark). The map reveals clusters of seismic activity along tectonic plate boundaries, such as the Pacific Ring of Fire, with larger circles indicating stronger earthquakes. Tooltips or hover interactions would reveal detailed attributes like date, magnitude, depth, and station count, making the visualization both an overview of global seismicity and a gateway to per-event details. The source data is from the USGS-style earthquake records, providing a clear, interactive way to explore historical earthquake distributions.

Earthquake Map

This map shows earthquake locations across the United States, with each quake colored by magnitude range from green (0-1.0) to red (3.0-4.0). The visualization uses d3.geoPath and d3.geoAlbersUsa to project USGS earthquake feed data onto state boundaries from a TopoJSON file, with d3.legendColor providing the magnitude legend. Separate SVG layers render quakes for each magnitude bin, and text annotations display counts per category.

draft earthquake data

This visualization uses earthquake data from a USGS dataset to map seismic events by location and magnitude on a world map. Each earthquake is represented as a circle, with its size scaled by magnitude and its position determined by latitude/longitude coordinates. The depth of the quakes is encoded through color, creating a gradient from shallow to deep events. The map is rendered with SVG paths for continents, and a custom tooltip provides details on click or hover. Circles are drawn with D3's data-join and scaled using a linear magnitude scale, while the map projection and graticule are set up with D3's geo utilities. The visualization highlights the global distribution and intensity of recent seismic activity, with Nepal, Japan, and the South Pacific clearly standing out.

Ver04 of Magnitude of Earthquakes - Added Responsiveness

This interactive scatter plot visualizes earthquakes from the past seven days, showing magnitude over time while color-coding each point by depth category—red for shallow, blue for intermediate, and green for deep quakes. The visualization uses D3 scales and axes to map the data, and implements responsive rendering via `observeResize` and the `axes` helper library, adapting to container size changes. Circles enlarge on mouseover through D3 transitions. The plot fetches data from the publicly available Earthquake Dataset on VizHub.
