Odds & Ends: Rabaul Volcano Erupts (in 1999)

September 19th, 2011 by Robert Simmon

Once upon a time Landsat images were expensive (Landsat 7 data was $600 per scene, and the earlier satellites were even pricier) and difficult to find. Now the data—which dates to 1972—is free, and reasonably easy (or at least not painfully difficult) to browse and download from the Global Visualization Viewer, or even the Google Earth Engine (which still has some rough edges).

An ash plume rises from Tavurvur Volcano (part of the Rabaul Volcanic Complex) on November 19, 1999. NASA/USGS Landsat 7.

There are some amazing things buried in the archive, like this natural-color image of an eruption at Rabaul. According to the Global Volcanism Program the activity at the time was “continuous, forceful emissions of thick, light-to-dark gray ash clouds.”

Poke around, and let me know what you find.
