ICI

Five of the 1992-93 shirt sponsors - Commodore, Fisons, ICI, Mita Copiers and Tulip Computers - have since gone out of business.

On the day of the accident, the driver of the tow truck that was called in to remove the campervan told the Ici news website: "I've never seen anything like it in my 22-year career."

The video was recorded from an observation post located next to an evacuation site in a field at Gam Ici village.

At the time of the eruption, the wind was blowing to the west, and as a result the volcanic material was carried by the wind down to a site where people previously evacuated have been living, in a field at Gam Ici village, said National Disaster Management Agency spokesperson Abdul Muhari.

So, they created a model using a technique called variable length Markov chains, which allowed them to estimate the probability of observing a specific ICI, based on the previous one.
