Puyehue Volcanic Range Continues Ejecting Ash

Puyehue continues to spew ash as volcanic seismicity re-intensifies: Reports

Chilean officials expand the evacuation zone around a volcanic complex as it continues to eject thousands of tons of ash each hour.

The national emergencies office (ONEMI) fears that volcanic ash and pumice could clog up rivers and waterways causing flooding, or trigger lahars, as rain hits the area.

The rain is expected to continue for at least several days.

“The forecast is for more rain on Tuesday, Wednesday and Thursday,” an ONEMI official told a local news agency.
