Dhaka on Banks of Buriganga River, Bangladesh

April 7th, 2012 Category: Rivers

Bangladesh - April 6th, 2012

This APM image shows the city of Dhaka, the capital of Bangladesh, appearing here as a yellowish area. The city is located in central Bangladesh on the eastern banks of the Buriganga River. The city lies on the lower reaches of the Ganges Delta and covers a total area of 360 square kilometres (140 sq mi). Tropical vegetation and moist soils characterize the land, which is flat and close to sea level. This leaves Dhaka susceptible to flooding during the monsoon seasons owing to heavy rainfall and cyclones (click here to see images of cyclones near Bangladesh).

Indonesia - January 4th, 2012

This APM image shows several volcanoes on the island of Java, Indonesia. Visible near the bottom edge is Mount Sumbing or Gunung Sumbing, an active stratovolcano in Central Java, Indonesia, symmetrical with Sundoro. The only report of historical eruptions is from 1730. It has created a small phreatic crater at the summit.

Moving to the northwest of Mount Sumbing one comes to  Mount Gede, followed by the Dieng Volcanic Complex. The complex of volcanoes is located on the Dieng Plateau in the Central Java, Indonesia. The volcanic complex consists of two or more of stratovolcanoes, more than 20 small craters and Pleistocene-to-Holocene age volcanic cones.The Prahu stratovolcano was truncated by a large Pleistocene caldera and then filled by parasitic cones, lava domes and craters.

Indonesia - January 7th, 2012

This APM image shows the city of Semarang, located on the northern coast of Java, Indonesia. The capital of the province of Central Java, it has an area of 305.17 km². The northern part of the city is built on the coastal plain while the southern parts are on higher ground.

Four stratovolcanoes can be observed in a curved line due south of Semarang: (from top to bottom) the deeply eroded Mount Ungaran, Mount Telomoyo, the dormant Mount Merbabu and the active Mount Merapi. In the lower left quadrant are two active stratovolanoces: Mount Sundoro (left) and Mount Sumbing (right).

Mexico - January 3rd, 2012

This APM image shows a change from mountains to flat terrain by the border of Chiapas, Mexico and Guatemala. Visible in the upper left quadrant is the Lacandon Jungle (Spanish: Selva Lacandona), an area of rainforest which stretches from Chiapas, Mexico into Guatemala and into the southern part of the Yucatán Peninsula. The heart of this rainforest is located in the Montes Azules Biosphere Reserve in Chiapas near the border with Guatemala in the Montañas del Oriente region of the state.

The Lacandon has approximately 1.9 million hectares stretching from southeast Chiapas into northern Guatemala and into the southern Yucatán Peninsula. The Chiapas portion is located on the Montañas del Oriente (Eastern Mountains) centered on a series of canyonlike valleys called the Cañadas, between smaller mountain ridges oriented from northwest to southeast. It is bordered by the Guatemalan border on two sides with Comitán de Domínguez to the southwest and the city of Palenque to north.

The dark red spot near the right edge of the image is the Laguna Lachuá, a Karstic lake in Guatemala. It is located in the middle of a national park covered with tropical rain forest, northwest of Cobán, near the border between the departments of Alta Verapaz and El Quiché. The lake is near circular in shape and is probably a cenote or doline. The Peyan river forms the principal water inflow and the Lachua river its main outflow.

Bangladesh - January 7th, 2012

Visible along the left edge of this APM image of southern Bangladesh is the easternmost part of the Sundarbans, the largest single block of tidal halophytic mangrove forest in the world. The Sundarban forest lies in the vast delta on the Bay of Bengal formed by the super confluence of the Padma, Brahmaputra and Meghna rivers across Saiyan southern Bangladesh. The seasonally-flooded Sundarbans freshwater swamp forests lie inland from the mangrove forests on the coastal fringe.

The Sundarbans is intersected by a complex network of tidal waterways, mudflats and small islands of salt-tolerant mangrove forests. Here, even after moving farther eastward beyond the limits of the forest, one can still see many rivers in the Barguna District. The district has a total area of 1831.31 km². Important rivers of Barguna district include the Payra River, Bishkhali River and the Baleshwar River.
