In 2015, researchers found that the volcano's structure bore patterns of magnetic striping on either side, indicating that the volcano is likely a hybrid of a mid-ocean ridge and a shield volcano. Geologic data also indicated that Tamu Massif formed at the junction of three mid-ocean ridges, which was a highly unusual occurrence. [14]
The volcano formed when magma worked its way to the surface and encountered water-laden, unconsolidated sediments with the existing water rapidly vaporizing into steam resulting in an enormous explosion that formed an explosion crater. Explosive eruptions continued at Pilot Knob as new magma encountered more water in the volcanic ash.
There are around 200 volcanoes in Texas that have been extinct for millions of years, making them unlikely to erupt again, because the volcano no longer has a magma supply.
World map with the middle latitudes highlighted in red Extratropical cyclone formation areas. The middle latitudes, also called the mid-latitudes (sometimes spelled midlatitudes) or moderate latitudes, are spatial regions on either hemisphere of Earth, located between the Tropic of Cancer (latitude 23°26′09.7″) and the Arctic Circle (66°33′50.3″) in the northern hemisphere and ...
Texas has been the leading state in petroleum production since discovery of the Spindletop oil field in 1901. [11] As of October 2017, the State of Texas (if treated as its own nation) is the 7th largest oil producing nation in the world, with production totaling approximately 3.78 million barrels (600 thousand cubic meters ) per day of oil ...
The geography of Texas is diverse and large. Occupying about 7% of the total water and land area of the U.S., [1] it is the second largest state after Alaska, and is the southernmost part of the Great Plains, which end in the south against the folded Sierra Madre Oriental of Mexico.
Big Bend National Park is a national park of the United States located in West Texas, bordering Mexico.The park has national significance as the largest protected area of Chihuahuan Desert topography and ecology in the United States, [3] and was named after a large bend in the Rio Grande/Río Bravo.

The Texas cities of Midland, Odessa and San Angelo serve as headquarters for some of the oil production activities in the basin. The Permian Basin is also a major source of potassium salts . Potash mines are located in Lea and Eddy counties, New Mexico, and are operated by the room and pillar method.
