Will Krakatoa explode again?

As the volcano collapsed into the sea, it generated a tsunami 37m high – tall enough to submerge a six-story building. And Indonesia has no advanced early warning system in place for volcano-generated tsunamis. At some point in the future, Anak Krakatoa will erupt again, generating more tsunamis.

What is Krakatoa lava type?

Mount Krakatoa’s lava was known to be made of dacite or rhyolite. This explains the magnitude of its eruption. Generally speaking, volcanic eruptions are more explosive if their lava is composed of dacite or rhyolite. They are cooler and stickier than basalt, allowing them to accumulate pressure before being set free.
