![]() "We looked at their distribution using different spatial statistics to figure out whether the volcanoes are clustered around other structures on Venus or if they're grouped in certain areas."Īnd while 85,000 volcanoes on Venus may seem like a lot, Hahn claimed it is a conservative estimate. "They're the most common volcanic feature on the planet: they represent about 99 percent of my dataset," Hahn said. The new study includes in-depth examinations of the locations of volcanoes, their clustering patterns, and how their geographical distributions relate to planetary geophysical characteristics like crustal thickness.Īlso, Byrne and Hahn sought to investigate the smaller, fewer than 3-mile-wide volcanoes on Venus that previous volcano researchers had passed over. "People back then were manually hand-drawing circles around the volcanoes when I can just do it on my computer," she said. ![]() She explained that this tool wasn't available when the data first became available back in the '90s. "It was tedious, but I had experience using ArcGIS software, which is what I used to build the map." "We came up with this idea of putting together a global catalog because no one's done it at this scale before," said first author Rebecca Hahn in a press release, a graduate student in Earth and planetary sciences at Washington University. ArcGIS maps Venus' volcanic characteristics The publicly available map will provide scientists access to an enormous database for understanding Venus' volcanism and assist in determining where the next active lava flow may be. Now, planetary scientists Paul Byrne and Rebecca Hahn from Washington University have created the most comprehensive map of its 85,000 volcanoes, according to a paper published in JGR Planets on March 23. ![]() Since the discovery of active volcanism on Venus a few weeks ago, interest in exploring the planet has kicked up a notch lately. ![]()
