Marapi Volcano Update; Deadly Eruption Occurs, Pyroclastic Flows Generated

Описание: A deadly volcanic eruption just occurred at the towering Marapi volcano in Indonesia. Without any notable warning signs beforehand this volcano unexpectedly erupted, creating a 3 kilometer long pyroclastic flow. It is a scary truth to think about, but believe it or not sometimes volcanic eruptions can occur without any warning signs beforehand. I looked at the available data and noticed no highly elevated signs that would normally be expected before a volcanic eruption occurs.
