Somma volcano in the context of Fogo, Cape Verde

The Bromo (Javanese: ꦧꦿꦩ), or Mount Bromo (Javanese: ꦒꦸꦤꦸꦁ​ꦧꦿꦩ, Indonesian: Gunung Bromo), is an active somma volcano, a Hindu pilgrimage site, and part of the Tengger mountains, in East Java, Indonesia. At 2,329 meters (7,641 ft), it is not the highest peak of the massif, but is the most active and famous. The area is one of the most visited tourist destinations in East Java, and the volcano is included in the Bromo Tengger Semeru National Park. The name Bromo comes from the Javanese pronunciation of Brahma, the Hindu god of creation. At the mouth of the crater, there is an idol of Ganesha, the Hindu god of wisdom, which is worshipped by Javanese Hindus. Mount Bromo is located in the middle of a plain called "Sea of Sand" (Javanese: Segara Wedi or Indonesian: Lautan Pasir), a nature reserve that has been protected since 1919.

A typical way to visit Mount Bromo is from the nearby mountain village of Cemoro Lawang. From there it is possible to walk to the volcano in about 45 minutes, but it is also possible to take an organized jeep tour, including stops at the viewpoint of Mount Penanjakan (2,770 m (9,090 ft)) (Indonesian: Gunung Penanjakan). The sights on Mount Penanjakan can also be reached on foot in about two hours. Depending on the level of volcanic activity, the Indonesian Center for Volcanology and Disaster Mitigation sometimes issues a warning not to visit Mount Bromo.

Mount Vesuvius (/vəˈsuːviəs/ və-SOO-vee-əs) is a somma–stratovolcano located on the Gulf of Naples in Campania, Italy, about 9 km (5.6 mi) east of Naples and a short distance from the shore. It is one of several volcanoes forming the Campanian volcanic arc. Vesuvius consists of a large cone partially encircled by the steep rim of a summit caldera, resulting from the collapse of an earlier, much higher structure.

The eruption of Mount Vesuvius in 79 AD destroyed the Roman cities of Pompeii, Herculaneum, Oplontis, Stabiae and other settlements. The eruption ejected a cloud of stones, ash and volcanic gases to a height of 33 km (21 mi), erupting molten rock and pulverized pumice at the rate of 6×10 cubic metres (7.8×10 cu yd) per second. More than 1,000 people are thought to have died in the eruption, though the exact toll is unknown. The only surviving witness account consists of two letters by Pliny the Younger to the historian Tacitus.

Cosigüina (also spelt Cosegüina) is a stratovolcano located in the western part of Nicaragua. It forms a large peninsula extending into the Gulf of Fonseca. The summit is truncated by a large caldera, 2 x 2.4 km in diameter and 500 m deep, holding a substantial crater lake (Laguna Cosigüina). This cone has grown within an earlier caldera, forming a somma volcano. The earlier caldera rim is still exposed on the north side, but has been buried by the younger cone elsewhere.

Mount Somma (Italian: Monte Somma, lit. 'Mount Summit') is a mountain located in the Province of Naples, in the Campania region of southern Italy. It is 1,132 metres (3,714 ft) high. It is an integral part of the Somma–Vesuvius volcanic complex and of the larger Campanian volcanic arc, which is known for its high levels of seismic and volcanic activity.

The volcano is believed to have formed over 25,000 years ago. It has a collapsed caldera of an older volcano, with Mount Vesuvius rising up from the center. Despite the potential dangers associated with living near an active volcano, the Somma volcano and its surroundings are a popular tourist destination. The mountain lends its name to somma volcanoes, which have a cone rising from within an older caldera.
