Final answer:
Since the late 1960's, most of the Hawaiian volcanic eruptions have occurred due to the hot spot located under the island of Hawaii.
Step-by-step explanation:
The answer to the question is volcanic eruptions.
Since the late 1960's, most of the Hawaiian volcanic eruptions have occurred.
These eruptions are a result of the hot spot located under the island of Hawaii.
The hot spot has been active for at least 100 million years and has generated a 3500-kilometer-long chain of volcanic islands. The Hawaiian volcanoes, including Mauna Kea, are among the largest individual mountains on Earth.
