Question: What is the name of the active volcano in Mexico that has the city of Tetela del Volcan located on its slopes?
Context: Santo Domingo Hueyapan is a small town in the rural northeastern part of the Mexican state of Morelos, in the municipality of Tetela del Volcán.  It lies at an elevation of ca 2000–2500 metres above sea level on the southern slopes of the active volcano Popocatépetl.  To the west of Hueyapan runs the Amatzinac river, to the north is the Popocatépetl-Iztaccíhuatl natural reserve, and to the south the town of Tlacotepec and to the east is the municipality of Tochimilco which belongs to the state of Puebla.  located in the midlands. Cerro Tipas (also known as Cerro Cazadero or Cerro Walther Penck) is a massive complex volcano in the Andes, located in northwestern Argentina.  It is just southwest of Ojos del Salado, the highest volcano in the world.  Tipas itself is perhaps the third highest active volcano in the world, and it consists of stratovolcanoes, lava domes, and lava flows.  Its summit is 6668 m above sea level and the complex covers a surface area of 25 km2 .  There are reports of fumarolic activity, and de Silva and Francis (1991) considered that the volcano was last active in the Holocene.  The Tipas-Cerro Bayo complex was active 2.9-1.2 million years ago with dacites and rhyolites. Magma composition is typical for Andean stratovolcanoes.  Tomographic studies of the underlying crust indicate a pattern of seismic attenuation beneath Tipas. Mt Bagana is an active volcano located in the centre of the island of Bougainville, Papua New Guinea, the largest island of the Solomon group.  It is the most active volcano in the country, occupying a remote portion of central Bougainville Island. Barren Island is an island located in the Andaman Sea, dominated by Barren Volcano, the only confirmed active volcano in South Asia.  And the only active volcano along a chain of volcanoes from Sumatra to Myanmar.  Along with the rest of the Andaman Islands, it is a part of the Indian Union Territory of Andaman and Nicobar Islands, and lies about 138 km northeast of the territory's capital, Port Blair. Mount Shishaldin is a moderately active volcano on Unimak Island in the Aleutian Islands chain of Alaska.  It is the highest mountain peak of the Aleutian Islands.  The most symmetrical cone-shaped glacier-clad large mountain on earth, the volcano's topographic contour lines are nearly perfect circles above 6500 ft .  The lower north and south slopes are somewhat steeper than the lower eastern and western slopes.  The volcano is the westernmost of three large stratovolcanoes along an east–west line in the eastern half of Unimak Island.  The Aleuts named the volcano Sisquk, meaning "mountain which points the way when I am lost."  The upper 2,000 meters is almost entirely covered by glacial snow and ice.  In all, Shishaldin's glacial shield covers about 35 sqmi .  It is flanked to the northwest by 24 monogenetic parasitic cones, an area blanketed by massive lava flows.  The Shishaldin cone is less than 10,000 years old and is constructed on a glacially eroded remnant of an ancestral somma and shield.  Remnants of the older ancestral volcano are exposed on the west and northeast sides at 1,500–1,800 meters elevation.  The Shishaldin edifice contains about 300 cubic kilometers of material.  A very steady steam plume rises from its small summit crater which is about 500 ft across and slightly breached along the north rim. The Amatzinac river also called Tenango is a Mexican river in the states of Morelos and Puebla.  It flows south from its spring in the foothills of Popocatepetl and south through the canyon which is also called Amatzinac and reaches the dry plain near Chalcatzingo.  It gives waters to the municipalities of Tetela del Volcán, Zacualpan and Temoac.  In dry season the river is little more than a shallow stream but at the end of the rainy season it grows due to the meltwaters from the volcano. State Road 347 (NM 347) is a partially completed road that starts at Interstate 40 on the West Mesa, approximately 8 mi west of downtown Albuquerque.  It runs north-northeast, following Paseo del Volcan to its northern terminus at US-550 in Bernalillo.  Currently it exists in two discontinuous segments: the southern segment is 9.4 mi long, and follows Paseo del Volcan from I-40 to Paseo del Norte (NM 423) near Double Eagle II Airport.  The 10.2 mi northern section begins at Unser Boulevard in Rio Rancho and ends at US-550 in Bernalillo, which incorporates a 3.4 mile extension of Paseo del Volcan from Iris Road to US-550 that was completed in February 2011.  The remaining 10 mi segment from Paseo del Norte to Unser Boulevard is not yet built.  While the New Mexico Department of Transportation owns the right-of-way for the unbuilt section, its completion is contingent upon future growth within Albuquerque and Rio Rancho and the availability of funding. Santa Ana Star Center is a 7,000-seat multi-purpose arena in Rio Rancho, New Mexico, a suburb of Albuquerque.  The arena is located near the intersection of Unser Boulevard and Paseo del Volcan.  It is part of a larger "City Centre" project, which also includes a new city hall. Popocatépetl (] ; "Popōcatepētl" ] ) is an active volcano, located in the states of Puebla, Mexico, and Morelos, in Central Mexico, and lies in the eastern half of the Trans-Mexican volcanic belt.  At 5426 m it is the second highest peak in Mexico, after Citlaltépetl (Pico de Orizaba) at 5636 m . Tetela del Volcán or simply Tetela, is a town and municipality in the Mexican state of Morelos.  It is located on the slopes of the volcano Popocatépetl.  .
Answer: Popocatépetl
