The distribution patterns of airfall tephras produced by major explosive eruptions from Karkar volcano are unknown. However, these patterns can be estimated theoretically using monthly wind speeds and wind directions recorded at Madang, previously determined terminal velocities for volcanic particles of different sizes and densities, and different equations for the amount of lateral spread in eruption clouds. The western and southern parts of Karkar Island are the most vulnerable to ashfalls from major explosive eruptions.-from Author
