Quotes

 * Volcanic ash, despite the name, is dense as rock and can cause significant damage to structures, power lines and communications. It is also toxic because it contains chemicals such as sulfur, chlorine or fluorine, and it can therefore affect water supplies.
 * Marco Brenna (2022) cited in: "Force ‘astonishing’: volcanologist" in Otago Daily Times, 17 January 2022.
