Heat Clouds

Yogyakarta, Indonesia:

Indonesia's Mount Merapi volcano spewed hot clouds and ash rain early on Monday, a vulcanologist said, but there was no confirmation of reports of fresh lava flows.

Yogyakarta Administration Secretary Bambang Susanto had earlier told Elshinta news radio that, according to information he had received, the mountain "exploded" in the pre-dawn hours with lava and hot ash.

As I noted in an earlier post, those clouds can kill.
