It’s time to add another treasure to our folder of enlightening scientific visualizations, which has grown thick over the past few years thanks in large part to researchers attempting to understand black holesOpens in a new tab, planetsOpens in a new tab, and the SunOpens in a new tab. This time around we have a scientific visualization focused not on outer space, however, but on Earth, and the way it quakes throughout its outermost shell.
Outstanding animated globe shows a year worth of earthquakes by depth (July 2017 to July 2018). In the interactive online version you can click on each individual #earthquakeOpens in a new tab to learn more. Epic #datavizOpens in a new tab!

The 3D visualization was created by Product Engineer Raluca NicolaOpens in a new tab, who says she has fun “mapping things in 3D.” The visualization was inspired by a 30-day geographic information system (GIS) challenge initiated by Finnish geographer, Topi TjukanovOpens in a new tab. The challenge, which trended on twitter via the hashtag, #30DayMapChallenge, called for creating a map each day in the month of November 2019. The maps focused on topics such as “resources,” “population,” “climate,” and “funny.” The challenge resulted in tons of inventive maps—e.g. this one mapping the paths of tornadoesOpens in a new tab in the U.S. and this one optimizing journeys around LondonOpens in a new tab in order to circumvent densely populated areas.
Nicola’s 3D interactive visualization, which can be found hereOpens in a new tab, was made utilizing data from the United States Geological Survey (USGS) collected between July 2017 and July 2018. Clicking on any one of the large, colored dots located on the surface of the 3D Earth image—which looks a lot like the hologram of the Death Star from Star Wars, bee-tee-dubs—immediately brings up information on a given earthquake.

Although the little earthquake profiles note when a particular earthquake happened, where it hit, and how strong it was on the Richter scale, perhaps the most relevant bit of information concerns the depth at which it occurred in Earth’s lithosphere—the lithosphere is the outermost shell of a terrestrial-type planet, and on EarthOpens in a new tab, is made up of the crust and the portion of the upper mantle. It’s the depth that seems like the highlight here because it’s this feature of the 3D map that stands out as the most insightful. At least to those not all that familiar with the way seismic waves ripple throughout Earth.
Announcing #30DayMapChallengeOpens in a new tab in November 2019! Create a map each day of the month with the following themes ???
No restriction on tools. All maps should be created by you. Doing less than 30 maps is fine. #gischatOpens in a new tab #geographyOpens in a new tab #cartographyOpens in a new tab #datavizOpens in a new tab pic.twitter.com/6Go4VFWcJBOpens in a new tab

Nicola does note that the depth at which the earthquakes first occurred has been exaggerated by a factor of 8, which means all of these earthquakes happened much closer to Earth’s surface than it seems. But visualizations of dataOpens in a new tab can’t always be super-accurate, obviously, and this 3D map does its job of letting us know that Earth is in a state of constant tumult that seems quite unnerving when you stop and think about it. Or worse, when you see it visualized like something the Rebel Alliance wants to blow to smithereens.
What do you think about this 3D map of all the earthquakes around the world from July 2017 through July 2018? Has this visualization completely changed the way you think about earthquakes, or were you already familiar with these patterns? Map out your opinions in the comments!
