For the portion in the United States it is a transform boundaries, while in the Gulf of California it forms a series of transform and divergent portions.
Baja California is on the Pacific Plate and across the Gulf of California, the rest of Mexico is on the North American plate. Both plates are sliding, in a way that the Pacific Plate is moving to the northwest while the North American Plate is moving southeast. This is called a transform boundary between both plates.
Its epicenter was located on the convergent boundary between the Pacific and Cocos tectonic plates.
The Mexican American War.
The Sierra Madre mountain range in Mexico is located near a divergent plate boundary, where the North American Plate is moving away from the Pacific Plate. This boundary is associated with seismic activity and volcanism in the region.
The Treaty of Guadalupe Hidalgo settled the boundary dispute between the United States and Mexico.
Countries that share tectonic plates include Japan, which lies on the Pacific Plate, and the United States and Mexico, which are both situated on the North American Plate. Additionally, Iceland straddles the boundary between the Eurasian Plate and the North American Plate.
The border
One example is the border line that goes from the Rio Grande River in El Paso/Ciudad Juarez west to the Pacific Ocean; such artificial boundary limits the border between Mexico and California, Arizona and New Mexico.
It lies between the United States and Central America, and between the Gulf of Mexico and the Pacific Ocean.
Most of the Mexico-Belize border is defined by the Hondo River (Spanish: Rio Hondo).There is however, a Rio Hondo located in the US State of New Mexico, but it doesn't define any boundary with the country of Mexico.
