Floods in Southern Africa |
| Description |
A black web of water surrounds the Zambezi River in the top image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite on February 10, 2007. Mozambique was experiencing its worst floods in six years when the Zambezi flowed over its banks in January and February 2007, reported the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/RWB.NSF/db900SID/YZHG-6YCQR4?OpenDocument&rc=1&emid=FL-2007-000011-ZMB ]). As of February 12, an estimated 29 people had died and 60,000 had been evacuated from the river's banks. Early and heavy rains fell over the entire Zambezi Basin, pushing the Zambezi and many of its tributaries into flood stage. The floods are likely to worsen as the 2,574-kilometer-long river receives water from its swollen tributaries in Angola, Namibia, Zambia, and Malawi. Releases from the massive Cahora Bassa Reservoir, [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14110 ] which is reaching its capacity, are also expected to make flooding worse along the lower Zambezi. These images show the lower Zambezi where it meets the Shire River flowing south from Malawi, one of the most severely affected regions in Mozambique. The top image provides a remarkably cloud-free view of the floods, while the lower image, taken on December 31, 2006, shows the region before the rains started in January. The images were made with a combination of infrared and visible light to highlight the presence of water on the ground. Water is black or dark blue, while plant-covered land is green. Bare earth is tan and pink, and clouds are pale blue and white. Fires are outlined in red. Images such as these and photo-like, true-color images are provided by the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_SMozambique/2007041 ] on a daily basis.

| Description |
The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite acquired these two images of the Zambezi River in central Mozambique in February 2007 just four days apart. Over the course of a weekend, floods along the lower Zambezi River in Mozambique spread to a nearby branch, the Cuecue River. According to local news reports released by the Agencia de Informacao de Mocambique, the floods along the Zambezi started to drop on February 20, though water levels on the lower Zambezi, shown here, remained high. As the top image shows, some of the water is draining into smaller offshoots along the river valley and into the Indian Ocean. These images use both visible and infrared light to increase the contrast between water and land. In this color combination, water is black or dark blue, while bare ground is tan and plant-covered land is green. Clouds are blue and white. The Sun's reflection off the surface of the water turns the river pale blue in the top image, and a web of flood water surrounds the dark line cut by the Zambezi River across the center of both images. South of the fresh floods on the Cuecue River, several dark spots along the Zambezi indicate additional flooding. To see daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Mozambique/2007051 ] of the flood area in central Mozambique, please visit the MODIS Rapid Response web site. The floods started when unusually early and heavy rain pounded southern Africa in January and February 2007. The rains triggered floods that affected nearly 170,000 people in Angola, Madagascar, Malawi, Mozambique, Zambia, and Zimbabwe, said the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/RWB.NSF/db900SID/YSAR-6YLNES?OpenDocument ]). In Mozambique, the United Nations and other organizations were providing food to more than 120,000 evacuees as of February 20, said OCHA.

Seasonal floods along the Zambezi River |
| Description |
Heavy rains through the month of March have pushed a section of Africa?s Zambezi River to its highest level since 1958. Just as the mighty river turns east in its path to the Indian Ocean, and immediately before it thunders over the Victoria Falls, it passes through the low-lying plains of Namibia?s Caprivi Strip. This section of the river floods often as the wet-season rains fill the river. This year, the floods have come earlier than normal, and are rising to levels not seen in nearly 50 years. The Namibian government expects to evacuate 40,000 to 50,000 people from the region as the flood waters continue to rise, though only 20,000 have been affected as of April 1. In comparison, last year?s floods, which at the time were declared the worst the region had seen since 1958, forced 12,000 people from their homes. On March 31, 2004, the waters reached 6.89 meters, surpassing the peak of last year?s flood, 6.64 meters. So far, two people have died in this year?s floods. The Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) on the Aqua [ http://aqua.nasa.gov/ ] satellite captured this view of the flood in the Caprivi Strip on March 30, 2004. The false color image shows the flood water in an inky black in sharp contrast to the bright green vegetation. Bare ground is tan and clouds are light blue. The image is available in true-color [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004090-0330/Caprivi.A2004090.1205 ] and additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004090-0330/Caprivi.A2004090.1205.721 ]. The Zambezi River forms at a spring in northern Zambia, and flows south through Zambia and Angola before turning east in Namibia?s Caprivi Strip and flowing through Zimbabwe, Zambia, and Mozambique to the Indian Ocean. It is Africa?s fourth largest river system after the Nile, Zaire, and Niger Rivers. The high-resolution image also shows floods along the northern section of the river in Zambia at MODIS maximum resolution of 250 meters per pixel.

Flooding in the Zambezi Valley |
| Description |
The ribbon of blue flood water that surrounds the Zambezi River in the top image is not unusual. Every year, when the rainy season sets in over southern Angola and western Zambia, the river rises and spreads wide across its flood plain. The intense rains that fell from mid-December through March 2007 caused widespread flooding across southern Africa [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14125 ] from Angola to Mozambique. The floods caused dozens of deaths, displaced thousands, and caused extensive damage to both agriculture and infrastructure, said the Dartmouth Flood Observatory. [ http://www.dartmouth.edu/%7efloods/Archives/2007sum.htm ] Many of the deadly floods have occurred along various sections of the Zambezi and its tributaries. The floods shown here caused agricultural losses. In additional to being heavier than normal, the rains also came early, reported the Dartmouth Flood Observatory. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image on March 4, 2007. The lower image was taken on December 1, 2006, by the MODIS sensor flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite, and is provided here to show the river during the dry season. The images were made with visible and infrared light to highlight the presence of water on the ground. Water is dark blue, while the surrounding plant-covered land is green. Bare or lightly vegetated ground is tan, and clouds are pale blue and white.

| Explanation |
On December 4th [ http://sunearth.gsfc.nasa.gov/eclipse/TSE2002/ TSE2002.html ], for the second time in as many years, the Moon's shadow will track [ http://sunearth.gsfc.nasa.gov/eclipse/TSE2002/TSE2002txt/ T02animate.html ] across southern Africa bringing a total solar eclipse [ http://www.mreclipse.com/Special/SEprimer.html ] to African skies. Reaching Africa just before 6:00 Universal Time [ http://aa.usno.navy.mil/faq/ docs/UT.html ], the narrow path of totality - corresponding to the path of the Moon's umbra or dark central shadow - will run eastward through Angola, Namibia (Caprivi Strip), Botswana, Zimbabwe, South Africa's Kruger National Park [ http://profjohn.com/el/el2002/index.html ], and Mozambique. Moving out across the Indian Ocean it will ultimately cross onto the Australian continent at sunset (around 9:10 UT [ http://www.csiro.au/helix/eclipse/ ]). Observers directly in this path could catch at most a minute or so of the eclipse at its total phase, but at least a partial eclipse will be visible over much of Africa, Australia [ http://astronomy.swin.edu.au/solar_eclipse_2002/ ], some parts of Indonesia, and eastern Antarctica. While watching [ http://www.mreclipse.com/TSE01reports/ TSE01galleryA.html ] last year's June 21 eclipse, astronomer Fred Espenak recorded a series of exposures used to construct this dramatic composite image. The sequence follows the 2001 geocentric celestial event from start to finish above a thorny acacia tree [ http://www.blueplanetbiomes.org/ acacia_tortillis.htm ] near Chisamba, Zambia. |
