Topography of the Isthmus of Tehuantepec, Mexico

17.6N 94.9W

Mexico - December 29th, 2011

This wide-swath ASAR image shows the Isthmus of Tehuantepec, an isthmus in Mexico that represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. The isthmus includes the part of Mexico lying between the 94th and 96th meridians west longitude, or the southeastern parts of Veracruz and Oaxaca, including small areas of Chiapas and Tabasco. The states of Tabasco and Chiapas are east of the isthmus, with Veracruz and Oaxaca on the west.

At its narrowest point, the isthmus is 200 km (120 mi) across from gulf to gulf or 192 km (119 mi) to the head of Laguna Superior on the Pacific coast. The Sierra Madre breaks down at this point into a broad, plateau-like ridge. The northern side of the isthmus is swampy and densely covered with jungle. Visible in the upper right quadrant is the Términos Lagoon.

The Sierra Madre de Oaxaca mountains flatten out to form Chivela Pass before the Sierra Madre de Chiapas mountains resume to the south, so geographically the isthmus divides North America from Central America. However, the southern edge of the North American tectonic plate lies across the Motagua Fault in Guatemala, so geologically, the division between North America and Central America (on the Caribbean Plate) is much farther south than the isthmus of Tehuantepec.

Mexico - March 30th, 2011

While the land of the Yucatan Peninsula (above) is mostly flat, mountains can be seen to the south in this image of Mexico, Guatemala, Belize, Honduras and El Salvador (clockwise from left).

The mountains are a continuation of the Sierra Madre del Sur called the Sierra Madre de Chiapas. The extremely volcanic range runs from northwest to southeast along the Pacific Ocean coast.

Mexico - December 23rd, 2010

This FAPAR image shows the vegetation index of the Yucatán Peninsula in Mexico as well as Belize, Guatemala, and parts of El Salvador and Honduras.

The peninsula shows a vegetation index ranging from good (green) to high (rusty red). The lowest vegetation index (yellow) can be observed near the southern coast by the Sierra Madre Mountains.

Yucatan Peninsula and Sierra Madre Mountains, Mexico and Guatemala

Mexico and Guatemala - December 23rd, 2010

Green sediments can be observed along the western and eastern shores of the Yucatán Peninsula in Mexico. Sediments are often present here, particularly along the western coast by the Laguna de Términos (Términos Lagoon) and the Bay of Campeche.

The southern shoreline appears sediments free. A range of mountains, the Sierra Madre (known in Mexico as Sierra Madre de Chiapas), can be noted parallel to the coast, running northwest-southeast from the state of Chiapas in Mexico across Guatemala and into El Salvador and Honduras.

Lakes and Mountains in Tabasco and Chiapas, Mexico

Mexico - June 2nd, 2010

This APM image shows mountains and many lakes in Tabasco and Chiapas, Mexico. The largest lake visible is the Catazajá Lagoon, with a surface area of 16,000 hectares.

The mountains below belong to the Central Highlands and Sierra Madre de Chiapas. A continuation of the Sierra Madre del Sur, the Sierra Madre de Chiapas runs from northwest to southeast along the Pacific Ocean coast. It is extremely volcanic, resulting in high peaks, occasional eruptions and earthquakes, and rich soils.
