GIS News: Volcano Eruption in Chile, OGC Seeking Public Comments

| |

The latest GIS news includes an image showing the drift of sulphur dioxide from the Puyehue-Cordón Caulle eruption in Chile, announcements from Esri, Topcon, and Maponics; also, the OGC is seeking public comments.


The latest “image of the week” from ESA shows the huge plume of sulphur dioxide that spewed from Chile’s Puyehue-Cordón Caulle Volcanic Complex.  The volcanoes lie about 600 km south of the city of Santiago in the Andes mountain range.  The area had been dormant for 50 years before erupting on June 4th.  A plume of volcanic ash and sulphur has risen as high as 10km.  Of the more than 3000 Chilean volcanoes, 80 are currently active.

The pattern of the plume was captured using Infrared Atmospheric Sounding Interferometer on Eumetsat’s MetOp-A satellite.
