students are learning about volcanic eruptions and their risk factors. hawaii experienced a major volcanic eruption on may 3, 2018. table 1 shows the number of earthquakes by month prior to the volcanic eruption. table 1. number of earthquakes by month in 2018 month number of days in month number of earthquakes january 31 11 february 28 10 march 31 16 april 30 36 may 2 62 source: usgs which statement best describes how the number of earthquakes and volcanic eruptions are related? a a small increase in earthquakes over a long period of time can suggest a volcanic eruption is about to happen. b a small decrease in earthquakes over a long period of time can suggest a volcanic eruption is about to happen. c a large increase in earthquakes over a short period of time can suggest a volcanic eruption is about to happen. d a large decrease in earthquakes over a short period of time can suggest a volcanic eruption is about to happen.

Answer

Brief Explanations:

Volcanic eruptions are often preceded by increased seismic - activity. A large number of earthquakes in a short time period can be an indication of magma movement and stress build - up in the Earth's crust, which may lead to a volcanic eruption.

Answer:

C. A large increase in earthquakes over a short period of time can suggest a volcanic eruption is about to happen.
