Shōwa-shinzan is a volcanic lava dome in the Shikotsu-Toya National Park, Hokkaido, Japan, next to Mount Usu. The mountain was created between 28 December 1943 and September 1945. Initially, a series of strong earthquakes shook the area, and wheat fields were rapidly uplifted. Lava broke through the surface and the current peak was created. The peak is now 398 m (1,306 ft) tall, and still actively smoking.

Parícutin is a cinder cone volcano located in the Mexican state of Michoacán, near the city of Uruapan and about 322 kilometers (200 mi) west of Mexico City. The volcano surged suddenly from the cornfield of local farmer Dionisio Pulido in 1943, attracting both popular and scientific attention.
