Forked from Simple World Map

This map visualizes global earthquake activity from the past week, highlighting that most events cluster along tectonic plate boundaries, particularly around the Pacific Ocean. Circle size corresponds to magnitude, while color indicates depth category (shallow, intermediate, deep). The visualization uses D3’s geoEquirectangular projection, fetch and json for loading data from the USGS earthquake feed and tectonic plate GeoJSON, and includes dropdown menus to filter by depth and magnitude. Users can click circles to open earthquake detail pages, drag to rotate the globe, and zoom via D3’s zoom and drag interactions.

AI-generated description

This map intuitively shows that the majority of the earthquakes occurred along the boundaries of the plates. There are more earthquakes around the Pacific Ocean than in other places on Earth. The region along the south coastline in Alaska and the west coast of America has the most seismic activity. These earthquakes are predominantly less than Magnitude 2.5 (M2.5). Luckily, this is a level that won't cause damage and is not felt by humans. Click and Check the Earthquake Magnitude Scale, cited from Michigan Tech.

  • use data from an API
  • circle size related to magnitude value
  • interaction: click circle and direct to a url
  • added color to the circles, according to depth (shallow, intermediate, deep)
  • added interaction: dragging to make the earth turn left and right.
  • added dropdown menus. User can select to view earthquakes by choosing depth and magnitude.
  • added tooltip
  • added zoom

Fork of Earthquakes on Map

This map depicts global earthquake epicenters, with circle size scaled by magnitude and color coding by depth category—shallow (red), intermediate (blue), and deep (green). Tectonic plate boundaries overlay the landmasses, visually confirming that seismic activity concentrates along plate edges. The visualization uses d3-geo projections, topojson for world map data, and USGS earthquake feed JSON. Interactive features include drag-to-rotate, zoom, dropdown filters for depth and magnitude, tooltips, and clickable circles that open event details.

Ver6 Earthquakes

This interactive map visualizes the world's recent earthquakes as colored circles on a geographic projection. Users can filter the display by earthquake depth and magnitude through dropdown menus, revealing patterns in seismic activity. Circle size corresponds to magnitude, while color indicates depth category (shallow, intermediate, or deep). The visualization uses d3.geoEquirectangular to project the map, fetches live earthquake data from the USGS API, and includes tectonic plate boundaries for context. Earthquake circles link to event detail pages and display a tooltip with magnitude, location, time, and depth on hover. Users can drag the globe to pan the world view.

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.

Earthquake Map

This map visualizes global earthquake activity over a two-week period in September 2015. Each circle marks an earthquake, sized by magnitude and colored by depth, with larger and darker circles indicating stronger, shallower events. The visualization uses the D3.js library to project earthquake epicenters onto a world map, with a legend clarifying the depth-color mapping and magnitude scaling. The map is rendered with SVG, with circles positioned by latitude and longitude coordinates from the dataset. The included data shows a cluster of significant seismic activity off the coast of Chile, as well as events across the Pacific Ring of Fire. The visualization effectively communicates the global distribution of earthquakes and relative intensities through its circle sizing and color scheme.

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.

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.

Ver4 Earthquakes

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.

Ver6 Earthquakes

This visualization shows earthquakes from the USGS live feed on an interactive 3D globe, with circle size representing magnitude and color indicating depth category (shallow, intermediate, deep). Users can filter earthquakes using dropdown menus for depth and magnitude ranges. Clicking a circle opens the earthquake’s details page; hovering reveals a tooltip with location, time, and depth. The map uses d3.geoOrthographic with drag-to-rotate, and fetches world map data from topojson and tectonic plate boundaries as GeoJSON.
