Forest Fires Across Central
…
| Title |
Forest Fires Across Central Siberian Plateau |
| Description |
On the Central Siberian Plateau, the northeastward direction of the Lena River is turned sharply northward as the river encounters the Verkhoyanskiy Mountains. The river flows northward along the base of the range for several hundreds more miles before emptying into the Arctic Ocean via the Laptev Sea. In the area where the Lena rounds this sharp corner, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite detected numerous fires (marked in red) burning in the region's boreal forests on July 7, 2005. As in Alaska, summertime thunderstorms in the northern forests often bring lightning that starts forest fires. Fires also start through carelessness or accidents of people visiting forests. In Russia's boreal forests, another major source of forest fires is arson. People set fires to acquire salvage logging permits, which are far cheaper than permits for other forests. The arsonists set fires that may only disturb underbrush and small trees, while leaving the bigger, more lucrative trees unscathed.

Flooding on the Lena River, Russia |
| Description |
*full-size images:* May 22, 2001 (1.4 MB) May 28, 2001 (1.4 MB) What a difference a week can make! This pair of true-color images acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS) on NASA's Terra [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://terra.nasa.gov/ ] satellite show the spring thaw and resulting flooding of the Lena River, a principal waterway of eastern Siberia. The first image, acquired on May 22, 2001, shows the Lena as a mostly frozen, white ribbon running north. An eastward flowing tributary, the Vilyuy, also appears frozen. In the second image, taken only 8 days later, large sections of the Lena, as well as the Vilyuy appear to be almost completely thawed. The formerly white ribbon of the river now appears decidedly brown, likely indicating sediment churned up by high water. The region is experiencing its worst flooding in one hundred years, with hundreds of thousands of people being affected by the floodwaters that have resulted from the melting of the snow pack accumulated over a particularly harsh Siberian winter. Explosives are being detonated in many places to dislodge huge blocks of ice that are backing up rivers and exacerbating flooding. The Lena River is one of the longest rivers in the world. It flows northeast and then north from its source in the Baikal Mountains south of the Central Siberian Plateau, and it empties into the Arctic Ocean via the Laptev Sea. At the mouth of the Lena River is a delta that is about 250 miles wide. The delta is frozen tundra for about 7 months of the year, but spring transforms the region into a lush wetland for the remainder of the year. Part of the area is protected as part of the Lena Delta Wildlife Reserve.
