Why do scientists want to know about volcanic eruptions in remote areas?

Because volcanoes in remote places are difficult for scientists who study volcanoes to know when one is erupting.

The Ring of Fire has many earthquakes and volcanic eruptions.?
Why do the areas along the ring of fire experience many volcanic eruptions and earthquakes?
Which of the following can lead to areas of frequent volcanic eruptions?
The movement of tectonic plates
Where are some of Earth's youngest rocks found?
Areas of recent volcanic eruptions such as the circum pacific regions.
Large depressed areas on the moon's surface once thought to be remnants of ancient seas?
These dark areas are called maria. They are thought to be formed by volcanic eruptions in the moon's history.
What instruments do scientists use to predict eruptions?
Scientists can not actually predict eruptions precisely, they can only detect changes in the earth that COULD precede an eruption and indeed eruptions could happen that were not predicted at all. They monitor volcanic areas with Seismometers (to detect earthquakes and sounds that may indicate the movement of magma). Monitor the gases and water coming out of volcanic areas to detect changes that could indicate magma is moving and also monitor the changes in level of the Earth's surface in volcanic areas to see if magma at depth is "inflating" the ground. Finally they use satellites to monitor changes in the heat of the ground in volcanoes. They also look at past event to try and determine the character of the volcano. With all this they try and inform officials as to what is happening so that people can be evacuated. Sometimes their predictions are correct and sometimes the volcano does not erupt. The scientists value life so the tend to err on the cautious side, recognising that there is a danger of the "cry wolf too often" effect. The decisions are hard.
Do volcanic eruptions only cause destruction?
No. Volcanic eruptions can build mountains and form new land. Many occur in remote areas where there is not much to destroy.
The Ring of Fire has many earthquakes and volcanic eruptions.?
Why do the areas along the ring of fire experience many volcanic eruptions and earthquakes?
Why are farmers attracted to volcanic areas?
Volcanic eruptions include minerals which plants need and which improve soil fertility.
What are some areas that show signs of eruptions or volcanic activity in California?

Where is tuff rock found?
Tuff is usually found in and near areas that have experienced explosive volcanic eruptions.
Where are some of Earth's youngest rocks found?
Areas of recent volcanic eruptions such as the circum pacific regions.
What are the maria?
Lunar maria are areas on the moon where volcanic lava has flowed in the past. It is surmised that they result from asteroid or meteor strikes followed by volcanic eruptions.
Why do volcanic eruptions affect the temprature?
The volcanic eruptions affect the temperature due to the ash cloud it injects into the atmosphere. The ash cloud insulates the earth, preventing some of the warm of the sun from being absorb by the earth. This results in cooler temperatures in the affected areas.

Can lightning cause earthquakes?
No There are two main causes of earthquakes. Firstly, they can be linked to explosive volcanic eruptions; they are in fact very common in areas of volcanic activity where they either proceed or accompany eruptions. Secondly, they can be triggered by Tectonic activity associated with plate margins and faults. The majority of earthquakes world wide are of this type.
