Indonesian Island of Sumatra and Malay Peninsula in Southeast Asia

This FAPAR image shows the Indonesian island of Sumatra (below) and part of Malaysia on the lower end of the Malay Peninsula, although the entire peninsula including parts of Thailand and Myanmar is visible after opening the full version.

Most of the land appears green to red, indicating good to high levels of photosynthetic activity. Only a few areas appear yellow, indicating a low vegetation index.

Sumatra supports a wide range of vegetation types which are home to a rich variety of species, including 17 endemic genera of plants. The island has lost 48% of its natural forest cover since 1985, however, and many of the remaining species are endangered.

Sediments Around the Riau Islands, Indonesia

Sediments flow off the coast of the Indonesian island of Sumatra, around the Riau Islands, and into the Strait of Malacca.

The strait stretches 805 kilometers (500 miles) between the Malay Peninsula and Sumatra. Across from the Riau Islands, on the peninsula, is the city of Singapore.

Riau Islands is a province of Indonesia, consisting of Riau Archipelago, Natuna Islands, Anambas, and Lingga Islands. There are around 3,200 islands in the province.

Batam has a majority of the province’s population. Other populated major islands include Bintan and Karimun. Sizewise, however, the sparsely populated Natuna Islands are larger.

While the amount of sediments is densest, appearing golden brown, around the Riau Islands, sediments are also present along the entire coastline of Indonesia and the Malay Peninsula.

Sediments in the Bangka Strait

While clouds rest above the landscape of two of Indonesia’s islands, Bangka (above) and Sumatra (below), the Bangka Strait is cloud-free and lined with dark brown, golden tan, and green sediments.

These sediments come from big rivers carrying silt down from the mountains of Sumatra. They run through a large area of swampy lowlands before discharging into the Bangka Strait.

Like this eastern part of Sumatra, most of the geographical faces of the Bangka consist of lower plains, swamps, small hills, beautiful beaches, white pepper fields and tin mines.

Sediments and Swampy Plains of Sumatra, Indonesia – April 4th, 2009

Sumatra (also spelled Sumatera) is the largest island completely in western Indonesia. The interior of the island is dominated by two geographical regions: the Barisan Mountains in the west and swampy plains in the east.

In this eastern region, big rivers carry silt from the mountain, forming the vast lowland interspersed by swamps. Here, several rivers pour dark and light brown sediments into the sea, south of the Lingga Islands.

Even if mostly unsuitable for farming, the area is currently of great economic importance for Indonesia. It produces oil from both above and below the soil—palm oil and petroleum.

Ruptured Dam Causes Flooding Near Jakarta, Indonesia

Jakarta, Indonesia - March 27th, 2009

A dam burst south-west of the Indonesian capital Jakarta on March 27th, reports the BBC, killing at least 58 people. Flash floods of up to 4m (13ft) deep engulfed hundreds of homes in Cirendeu in the Tangerang district. The waters swept away houses, cars and telephone lines.

An official said the Situ Gintung lake behind the dam became overloaded after hours of heavy rain. The dam, which was an old, earthen structure 16m (52ft) deep, is thought to have released two million cubic metres (70 million cubic ft) of water.

Here, the Indonesian islands of Java (right) and Sumatra (left) are visible. Jakarta and Cirendeu,  near the northern coast on the far right, are partially covered by clouds.  Yellowish sediments frame the shorelines of both islands.
