Hurricane Katrina
2005/08/29

The disastrous hit of hurricane Katrina to southern coast of the US became the worst storm disaster in known American history. Heavy rain and high sea waves drowned New Orleans, the city of 480,000 people in seawater. This MODIS satellite image shows a closer view of deadly Katrina, before its landfall. This report wrote after the landfall and latest information indicated some hundreds of people might have killed by the disaster. In yesterday's MODIS image, the flooded region is visible through clouds (figure 01). Over 80% of the New Orleans city flooded and damage easily passed US$ 25 billion within first few days.

Raging Amazon forest fire

This MODIS satellite image is showing uncontrolled forest fire set for land clearance by Brazilian farmers. Fire is destroying even natural forests close to already cleared forests. These fires are causing no major threat to villagers, but they are contributing negativity for global warming. Satellite data are providing a very successful data source to detect and record these types of fires in very remote locations.

Pakistan earthquake
2009/10/09

A disastrous big earthquake occurred in northeast Pakistan, in the disputed area with Indian border. Magnitude 7.6 quake centered just near the Muzzafarabad city, which has about 0.2 million people. The weak building construction, shallow depth of the quake epicenter (10km), and aftermath landslides increased the death toll dramatically passing 20,000 within first three days. Map shows the hilly terrain of the region with some cities and tectonic plate boundary. Pakistan government news says the Muzzafaeabad city has completely destroyed. Telephone, power, water, and other public services were downed and mountain villages became inaccessible due to damaged roads. Pakistan meteorological department says this is the worst quake hit in this area within last 100 years. The disaster occurred after 10 months that the historical tsunami tragedy in Asia.

Hurricane damage
2005/09/12

Hurricane Katrina, which demolished coastal Louisiana, Mississippi, and Alabama states, became the costliest natural disaster in the US history. Latest records say death toll has passed 1,163 people with a total economic damage of about $200 billion. This NOAA aerial photograph shows one the hardest hit areas of the hurricane, Biloxi city region, east to New Orleans city of Louisiana. See the completely collapsed bridge and other damage locations (red arrows). The damage accompanied with after-hurricane flood caused by broken levee system that protect New Orleans city from Lake Pontchartrain. Estimated 1 million people displaced and about 5 million people lost power connection. Katrina was a category 5 hurricane and also was the 11th of the 21 storms hit in this hurricane season.

Heavy rains in India
2005/09/12

Heavy rains associated with a storm flattend India's southeast region, including Chennai city of Tamilnadu district. Remote areas received heavy damage from floods, including a killer train accident occurred near Valigonda city of Andhra Pradesh (mark as a red + on the image). Train crashed into a river, after the track washed away by flood. Image shows these intensive rains recorded within last 7 days. Authorities say about 100 people or more killed by the train disaster, apart from about another 100 deaths caused by flood. Satellite data based image shows heavy rains in purple color (over 500 mm within the 7 days). These rainfall data are coming from TRMM satellite, which is a joint project of the USA and Japan. TRMM data are useful to monitor rainfall conditions in remote areas and over oceans.
