'Strength is the most influential factor that affects primary and secondary hazards during an volcanic eruption'. To what extent do you agree. (more A-level)

Strength is a considerable factor, it affects the how severe primary affects will be, these can include pyroclastic flows, ash fall tephra, lava bombs and ground shaking. Increased ash fall tephra can also affect the secondary impacts, i.e destruction of housing leading to displacement and increased exposure to contaminated water leading to risk of water-borne diseases and resulting in loss of life. Also Hawaiian style eruptions verses Plinian style leads to less/no loss of life, but instead can lead to economic gains, as seen in Hawaii
However, level of development can be a important factor. For example, countries like the Philippines can are very vulnerable to the impacts of volcanoes due to lower standard of public services in LIDCs. Furthermore, in LIDC, limited funding can affect the effectiveness of primary response during a volcanic eruption potentially leading to more death, even if the eruption isn't as severe compared to more famous eruptions such as Mount Pinatubo (1991) or Mount St.Helens (1980)
