Think about Volcanic Hazards (Grades 9-12)
Activity 11 is an exercise designed to make students aware of the
and responsibilities of living on the Island of Hawaii. The hazard map
that is need for this activity is available on the
Hawaiian Volcano Observatory
Activity 11 Think about Volcanic Hazards
Read the following information about lava flow hazards on the island of
Hawaii and answer the questions below.
In 1974 Don Mullineaux and Don Peterson of the U.S. Geological Survey
published a report on the volcanic hazards on the Island of Hawaii.
Although the report was well written, accurate, and told of the dangers
of living on active volcanoes, it was largely ignored by the public. The
lack of dissemination of this useful information was probably due to
access to, or interest in, reading scientific reports. To remedy this
situation and in response to the hazard posed by the current eruption and
future eruptions the Hawaiian Volcano Observatory, in cooperation with
Hawaii County Civil Defense published Volcanic and Seismic Hazards on the
Island of Hawaii. This pamphlet is easy to read, well illustrated, and
available at public libraries. The pamphlet contains a lava flow hazard
map with 9 zones. Zone 1 is the summit areas and rift zones of Kilauea
and Mauna Loa Volcanoes. Zone 2 is the area adjacent to, and below, the
rift zones of Kilauea and Mauna Loa Volcanoes. The current eruption
originated in zone 1 of Kilauea's east rift zone and sent lava flows
downslope into areas designated as zone 2.
- What zone do you live in?
- Would you build your home in zone 1 or 2? Why or why not?
- Why do you think geologists make maps showing the hazards associated
- What would be the best way to disseminate this information to the
- Do you think the County of Hawaii should use the lava flow hazard map
to restrict new construction and development to only certain areas?
- Should government agencies supply funds to families that have lost
their homes to rebuild in zones 1 and 2?
