Lava shoots 1km high

Volcano monitors say Ecuador's Tungurahua volcano shot lava 1km above its crater overnight and blasted hot rock and gas nearly 3km down its flank.

The regional director for the government's emergency agency is Lourdes Mayorga and she said officials had prepared shelters and were working to evacuate any people in danger.

The country's National Geophysics Institute said the volcano blasted lava well above its crater overnight and sent out a plume of ash and gas about a 1.5km high.

The renewed eruption in central Ecuador began last week and plumes on Sunday (NZT Monday) rose as high as 5km above the 5023m crater.
