Sakurajima volcano in Japan: Detection of volcanic ash:

At the active Sakurajima volcano in Japan, it demonstrated its ability to measure volcanic ash (tephra). The study highlights the following points:

• Precision down to the last detail: Detects particles as small as 0.15 mm – ideal for fine volcanic ash.
• Real-time individual detection: Measures the fall velocity of each particle and distinguishes individual grains from aggregates.
• Robust & cost-effective: Developed for field use, more cost-effective than comparable systems.
• Complete grain size distribution (TGSD): Relevant data for ash dispersion models and aviation safety.
