Introduction

This report explores two active volcanoes that have erupted within the last 50 years, situated in different parts of the world. The aim is to analyze their geological features, eruption history, and activity types, providing comprehensive insights into their recent volcanic behaviors and characteristics.

Volcano 1: Mount Merapi, Indonesia

Name and Location

- Name: Mount Merapi

- Location: Indonesia, Central Java (7.542° S, 110.442° E)

- Elevation: 2,930 meters (9,610 feet)

- Last Eruption Date: 2020

Geological Setting

Mount Merapi exists due to subduction of the Indo-Australian Plate beneath the Eurasian Plate along the Sunda Arc, a convergent plate boundary. This tectonic activity results in magma generation and frequent eruptions, characteristic of stratovolcanoes in volcanic arcs.

Recent Eruption Activity

Merapi is renowned for its highly active and explosive eruptions, often producing pyroclastic flows and ash plumes. Its 2010 eruption was particularly significant, causing evacuations and ash dispersal over surrounding regions. In 2020, eruptions were characterized by strombolian activity with sporadic ash columns and dome growth, demonstrating its persistent unrest. An unusual aspect of recent eruptions is the occurrence of pyroclastic flows that traveled unusually far, influenced by its steep slopes.

Types of Eruption

- Usually: Strombolian and Vulcanian eruptions

- Recent activity: Predominantly Strombolian with occasional dome collapses

Type of Volcano

- Stratovolcano

Type of Lava

- Mainly andesite

Volcano 2: Mount Etna, Sicily, Italy

Name and Location

- Name: Mount Etna

- Location: Italy, Sicily (37.734° N, 15.004° E)

- Elevation: 3,329 meters (10,922 feet)

- Last Eruption Date: 2023

Geological Setting

Mount Etna is located at a divergent boundary where the African Plate is converging with the Eurasian Plate, and it is also influenced by the subduction of the African Plate beneath the Eurasian Plate. Its volcanic activity is driven by rifting and tectonic divergence, producing a complex stratovolcano with frequent eruptions.

Recent Eruption Activity

Etna has a long history of eruption activity, often occurring with strombolian to lava fissure eruptions. The 2023 eruption featured spectacular lava fountains and extensive lava flows. An unusual aspect of Etna’s recent activity is the formation of new vents and frequent lava fountain phases that can last for weeks, indicating intense magmatic movement.

Types of Eruption

- Usually: Strombolian and fissure eruptions

- Recent activity: Lava fountains with effusive lava flows

Type of Volcano

- Stratovolcano

Type of Lava

- Mainly basalt and andesite

Conclusion

Both Mount Merapi and Mount Etna demonstrate diverse volcanic behaviors consistent with their tectonic settings. Merapi’s frequent explosions and ash emissions contrast with Etna’s extensive lava flows and fissure eruptions, illustrating the variety of volcanic activity driven by different geological processes. Understanding their recent activity episodes offers valuable insights into volcanic hazards and the geodynamics of active tectonic zones worldwide.
