Isthmus of Tehuantepec Between Gulf of Mexico and Pacific Ocean, Mexico

Mexico – March 23rd, 2013

The Isthmus of Tehuantepec is an isthmus in Mexico. It represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. 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 northern side of the isthmus is swampy and densely covered with jungle.

The Sierra Madre breaks down at this point into a broad, plateau-like ridge. Since Sierra Madre de Oaxaca mountains flatten out to form Chivela Pass before the Sierra Madre de Chiapas mountains resume to the south, geographically the isthmus divides North America from Central America.

Mexico – December 22nd, 2012

A plume of smoke can be seen blowing southwestward over the Pacific Ocean near the center of this image, off the coast of the Mexican state of Oaxaca on the Isthmus of Tehuantepec. Another plume, this time composed of sediments rather than smoke, can be seen spilling from the Laguna Superior into the Pacific near the right edge.

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.

Lagoons Near Shores of Gulf of Tehuantepec, Mexico

Mexico - November 21st, 2011

A series of lagoons can be observed near the shores of the Gulf of Tehuantepec, including Laguna Superior (greyish tan, left) and Laguna Inferior (greenish blue, just right of the former), in the state of Oaxaca. The bright green lagoon to the right is shared between Oaxaca and Chiapas.

Laguna Superior marks the the narrowest point of the Isthmus of Tehuantepec, which is 200 km (120 mi) across from gulf to gulf, or 192 km (119 mi) to the head of the lagoon. The Sierra Madre breaks down at this point into a broad, plateau-like ridge, whose elevation, at the highest point reached by the Ferrocarril Transistmico railway at Chivela Pass, is 224 m (735 ft).

Mexico - April 13th, 2009

The Isthmus of Tehuantepec is an isthmus in Mexico that represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. Geographically, the isthmus divides North America from Central America.

The isthmus includes the southeastern parts of Veracruz and Oaxaca, which are on the west, as well as small areas of Chiapas and Tabasco, which are east of the isthmus. Here, part of the Yucatán Peninsula can also be seen to the right.

The Isthmus of Tehuantepec is 200 km (125 miles) across at its narrowest point from gulf to gulf, or 192 km (120 miles) to the head of Laguna Superior on the Pacific coast. The both coasts of the isthmus are relatively free of sediments, while that of the peninsula is not.

The Sierra Madre breaks down at this point into a broad, plateau-like ridge, whose elevation, at the highest point reached by the Tehuantepec railway at Chivela Pass, is 224 m (735 ft).

The northern side of the isthmus is swampy and densely covered with jungle, as can be observed from its green and brown colors.
