Geological | Solid material of all sizes explosively ejected from a volcano into the atmosphere. (Teacher's Packet) * Tephra is the general term now used by volcanologists for airborne volcanic ejecta of any size. Historically, however, various terms have been used to describe ejecta of different sizes. Fragmental volcanic products between 0.1 to about 2.5 inches in diameter are called lapilli; material finer than 0.1 inch is called ash. Fragments larger than about 2.5 inches are called blocks if they were ejected in a solid state and volcanic bombs if ejected in semi-solid, or plastic, condition. (Tilling, Heliker, and Wright, 1987)* See: Ash, Lapilli, Blocks, Bombs. (references) |
| General term for all sizes of particles ejected into the air during volcanic eruptions. Includes particles as tiny as volcanic ash and as large as bombs and blocks (= pyroclastics). (references) | |
