Semeru is erupting, 51 km south
Ash from the ground up to 15,000 ft, drifting northeast
That is over this city.
While ash is falling
Shelter indoors and close the windows.
Turn off air conditioning that draws air from outside.
An N95 filters ash best; a well-fitting surgical mask is second. Cloth is poor, and wetting it does not help.
Masks do not fit children — keep them inside.
Goggles protect the eyes; ash scratches them.
If you have a respiratory condition, carry your medication.
Dampen ash before sweeping it. Do not vacuum indoors.
An N95 does not stop volcanic gases.
