GEOLOGY

Detailed explanation-1: -True or False-Scientists can predict volcanic eruptions? FALSE-Scientists are not yet able to predict a volcanic eruption with certainty. There are clues that a volcano will erupt such as earthquakes and small eruptions.

Detailed explanation-2: -Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. Even so, the math doesn’t work out for the volcano to be “overdue” for an eruption. In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago.

Detailed explanation-3: -No. Neither the USGS nor any other scientists have ever predicted a major earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future.

Detailed explanation-4: -Just like earthquakes, predicting exactly when an individual volcano will erupt-and exactly how large that eruption will be-is still impossible. But deposits left by past eruptions, along with live data from volcanoes around the world, might help volcanologists make better forecasts.

Detailed explanation-5: -The warning time preceding volcanic events typically allows sufficient time for affected communities to implement response plans and mitigation measures.
