Nik Wallenda becomes the first person to walk over the Masaya Volcano in Nicaragua.

Nikolas Wallenda is an American acrobat, aerialist, daredevil, high wire artist, and author. He is known for his high-wire performances without a safety net. He holds 11 Guinness World Records for various acrobatic feats, and is best known as the first person to walk a tightrope stretched directly over Niagara Falls. Wallenda walked 1,800 feet (550 m) on a steel cable over Masaya Volcano in Nicaragua, his longest walk, on March 4, 2020.

Masaya is a caldera located in Masaya, Nicaragua, 20 km (12 mi) south of the capital Managua. It is Nicaragua's first and largest national park, and one of 78 protected areas of Nicaragua. The complex volcano is composed of a nested set of calderas and craters, the largest of which is Las Sierras shield volcano and caldera. Within this caldera lies a sub-vent, which is Masaya Volcano sensu stricto. The vent is a shield type composed of basaltic lavas and tephras and includes a summit crater. This hosts Masaya caldera, formed 2,500 years ago by an 8 km³ (1.9 cu mi) basaltic ignimbrite eruption. Inside this caldera a new basaltic complex has grown from eruptions mainly on a semi-circular set of vents that include the Masaya and Nindiri cones. The latter host the pit craters of Masaya, Santiago, Nindiri and San Pedro. Observations in the walls of the pit craters indicate that there have been several episodes of cone and pit crater formation.

March 4 is the 63rd day of the year in the Gregorian calendar; 302 days remain until the end of the year.
