What are some techniques scientist use to try to predict earthquakes and eruption of volcanoes?

Some things were theTiltmeter. It detects changes in the slope of a volcano. A change in the slope of a volcano might mean that magma is moving within the mountain. Also, there was the First Seismograph. It detected earthquakes.

∙ 14y agoVolcanic eruptions are often preceded by many warning signs including:
- minor earthquakes and tremors in the ground around a volcano or potentially volcanic zone;
- bulges in the volcano (as magma builds up and pushes the ground up too);
- increases in steam and gas output;
- increases in temperature;
- increases in minor volcanic activity.
Scientists currently cannot actually predict earthquakes in the same manner as volcanic eruptions; they can provide a probability that an earthquake of a given magnitude will happen in a given area in the next period of time, but that is all.
For further information on the tools seismologists use to monitor earthquakes and earthquake fault zones in an attempt to estimate the risk posed, please see the related question.

∙ 13y agoThere are many tools scientists can use to help predict an eruption. An example of one would be a Tiltmeter which can detect changes in the slope of a volcano. Other examples would be a GPS, camera, thermometer, seismograph, hammer etc, etc

Did the mt st Helen's eruption affect the land around it?
There is always earthquakes when volcanoes erupt, so, yes.
What do tsunami and volcanoes have to do with earthquakes?
When an Earthquake occurs that is when the ground shakes to create a tsunami or volcano eruption.
Is a seismometer used for earthquakes or volcanoes?
As magma, or molten rock, moves underground it creates earthquakes. The signature of magma-driven seismic waves is different from that of normal tectonic earthquakes. With multiple seismometers it is possible to determine where earthquakes are and whether or not they are migrating. If earthquakes are moving closer to the surface and closer to a volcano, that is a sign it might be getting ready for an eruption.
Why do earthquakes and volcanic eruptions frequently occur in the same area?
because a volcanic eruption happens after an earthquake
Are a dormant volcanoes still dangerous?
Yes. Even without an eruption a dormant volcano may be prone to earthquakes, landslides, and gas emissions.
How high does it have to be on the Richter scale to cause a volcano eruption?
Earthquakes do not cause volcanoes. However, magma moving to the surface rapidly can produce tremors. Volcanoes can cause earthquakes, but not vise-versa.
How are volcanoes earthquakes and tsunamis related?
A volcanic eruption can cause an earthquake and an earthquake underwater can cause a tsunami.
Do earthquakes cause volcanoes to explode?
In most cases, no. However, there is evidence that, on a few occasions, earthquakes appear to have triggered eruptions, most likely by disturbing the magma chamber beneath the volcano. Earthquakes often precede a volcanic eruption, be these are not the cause of the eruption, but are rather a result of the movement of magma that leads to an eruption.

What do tsunami and volcanoes have to do with earthquakes?
When an Earthquake occurs that is when the ground shakes to create a tsunami or volcano eruption.
Are volcanes bad or earthquakes?
Both are considered bad. Volcanoes, if the eruption is big enough, can damage a lot of land. However, earthquakes are more frequent and they can be very destructive.
Why do you study earthquakes and volcanoes together?
You study these together because sometimes an earthquake is the cause of a volcano eruption and vice versa.

What causes earthquakesand volcanoes to happen?
The earths plates rub together causing vibrations in the earth. Making Earthquakes If these plates are near volcanoes the friction will melt the magma causing a volcanic eruption.
Can volcanoes cause earthquakes?
Yes, volcano eruptions can cause earthquakes; they can also be caused by earthquakes or occur at the same time.Yes. Earthquakes are common around active volcanoes. They are usually triggered by the movement of magma beneath the earth and the fracturing of rock that results. However, volcanic earthquakes are not very large and generally do not cause much damage directly.
