8. Hydration cracks [Heiken and Wohletz, 1985] can be found on the surface of ash particles erupted on July 19–21. A broad range of texture and shape of vesicles is present in the samples: sideromelane and tachylite are the most and the least vesicular, and show smooth‐walled and jagged‐walled bubbles 300–10 μm in size, respectively.
