What type of volcano is Krakatau?

Question:

Krakatau a.k.a. Krakatoa:

Mount Krakatau is the Indonesian spelling and pronunciation of the volcano many of us know as Mount Krakatoa. It forms a volcanic island in the South Pacific and is part of Indonesia. In 1883, Krakatoa erupted in one of the most powerful events ever recorded (see figure). While only a few people died from the explosion itself, over 36,000 people died from the tsunamis it caused. Some of these waves reached 40 feet tall.

Mount Krakatau/Krakatoa is the small island in the middle of what was once the island before 1883

Features and Eruptions

• Krakatau forms an island in Indonesia's Sunda Strait, and this strait is located between Java and Sumatra islands. This island, which covers an area around 16 square miles, is made up of the caldera of the volcano, post-eruption. The island is part of the Indonesian Island Arc.
• This volcano's base reaches around 1,000 feet below sea level, while its cone once stretched around 6,000 feet above sea level. However, the volcano's cone now reaches 2,667 feet above sea level.
• Eruptions are the result of the Indo-Australian tectonic plate shifting towards Asia and subducting while doing so.
