If you are trying to learn Japanese then this day of the week in Japanese is Kin'ybi. There were 359 days remaining until the end of the year. Image courtesy of NASA/GSFC/MITI/ERSDAC/JAROS, and the U.S./Japan ASTER Science Team. Januwas the 6 th day of the year 2006 in the Gregorian calendar. Differences in lighting and cloudiness between the two parts of the image reveal that they were not captured at the same time. The seam between the two is visible in the upper left corner of the image. Images from two overpasses were stitched together to show the entire area. This image of Toba Caldera was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite on January 28, 2006. The rapid global cooling trend would have had profound consequences for life around the globe. “Volcanic winter,” caused by the increase in sunlight-reflecting particles high in the atmosphere, probably lasted several years. Very few creatures of any kind would have survived across a broad part of Indonesia. Looking at the incredibly lush tropical vegetation that covers much of the landscape, it is difficult to picture the complete destruction of plant and animal life-including human populations-that would have resulted from the eruption. The Pusukbukit Volcano on the western shore of the lake also formed after the catastrophic eruption.

Samosir Island is a resurgent volcanic dome, a mound of rock uplifted by pressure from un-erupted magma in the chamber beneath the volcano. As far away as India, ash from the Toba eruption lies in layers up to 6 meters (about 20 feet) thick on Samosir Island, the ash layer is more than 600 meters (more than a quarter mile) thick!įollowing the eruption, the ground collapsed, leaving the modern caldera, which filled with water to make Lake Toba. Pyroclastic flows (fast-moving clouds of hot gas, rock fragments, and ash) buried at least 20,000 square kilometers around the caldera. Over what was probably a two-week span, thousands of cubic kilometers of debris spewed from Toba Caldera on northern Sumatra. The corresponding story followed the path of the Delaware River, which travels for nearly 400 miles through 4 states. Around 70,000 years ago, the Earth was rocked by the largest volcanic eruption to have occurred in the past 2 million years.
