Question 11 (15 points) List 3 items we can monitor near a volcano to detect volcanic activities.

Three items you can monitor near a volcano to detect volcanic activities are as follows:

1.Seismometers, which are used to measure earthquakes occurring near an eruption.

2. Tiltmeters/GPS satellites, which are used to observe the geographical area. Volcanoes tend to swell up before they erupt.

3. Devices that measure temperature. Volcanoes tend to grow higher in temperature when magma starts to rise from the main vent

i took very good i wish you luck! i hope it .
