Volcanic ash reduces post-eruption road and runway surface safety

Volcanic ash settling on paved surfaces poses a major safety hazard. A study of skid resistance on road asphalt and airfield concrete surfaces helps inform recommendations for effective cleaning and road safety maintenance.

On the road to solutions for volcanic ash-affected transport links

Volcanic ash can play havoc with transport infrastructure, disrupting vital networks. The degree of disruption depends on particle size and deposit thickness, weather conditions, road surface materials and mitigation actions.

Role model for post-volcanic eruption clean-up

Volcanic ash fall (tephra) can damage or even destroy buildings and infrastructure and threaten health and well-being, along with having a massive impact on both the local and national economy.
