Mount Lewotobi Laki Laki, one of Indonesia’s most active volcanoes, is erupting for a second straight day, spewing towering columns of hot ash 6 miles high. Ash and debris blanketed villages, but no casualties were immediately reported. Indonesia’s Geology Agency said the volcano had two eruptions Wednesday after erupting three times Tuesday. One lit up the night sky with glowing lava and bolts of lightning. Officials warned residents to be vigilant about heavy rainfall that could trigger lava flows in rivers originating from the volcano. The volcano has been at the highest alert level since June and an exclusion zone was widened as eruptions became more frequent.
