Overview

• The instrument measures lava viscosity directly in volcanic environments, capturing data missed in lab conditions.
• Field trials in Iceland's Litli-Hrútur eruption demonstrated the tool's effectiveness and durability.
• Accurate viscosity data helps predict lava movement, crucial for evacuation plans and infrastructure protection.
• The tool's design includes a force gauge and displacement rod, making it lightweight and easy to use.
• Researchers aim to refine the instrument and distribute it to volcano monitoring stations globally.
