Forked from Earthquakes on Map

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.

AI-generated description

Previous version

  • 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.

Updated version

  • added dropdown menus. User can select to view earthquakes by choosing depth and magnitude.
  • fixed coding error on the colorscale
  • added tooltip

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.

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.

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.

Earthquakes on 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.

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.

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.

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 Ver6 Earthquakes_drb

This interactive visualization displays earthquake data from the USGS feed on an equirectangular world map, with tectonic plate boundaries overlaid. Users filter events by depth and magnitude through dropdown menus, while circle size encodes magnitude and color encodes depth category (shallow, intermediate, deep). The D3.js visualization supports dragging to rotate the globe, zooming, and clicking circles to open the USGS event page in a new tab. Hovering reveals a tooltip with magnitude, location, time, and depth. Data is fetched from the USGS GeoJSON API and the world atlas via `d3.geoEquirectangular` and `geoPath`.
