Some warning signs that a volcano may erupt include increased seismic activity such as earthquakes, changes in gas emissions like higher levels of sulfur dioxide, ground deformation or swelling, and increased heat flow from the volcano. Monitoring these indicators can help predict and warn of a potential volcanic eruption.
The temperature of rocks in the volcanic cone increase. There may also be changes in the shape of the volcanic cone. The cone may start to swell or bulge just before an eruption.
A number of increases in small earthquakes or tremors around a volcano are often a warning sign of an impending volcanic eruption which are caused by the movement of magma into a chamber under the volcano under high pressure which can cause fracturing of the country rock leading to seismic activity.
The commencement of emission of gas and steam from a volcano, as well as increase in emission volume or pressure and potentially a change in gas composition may all mark an increase in activity. Changes in groundwater chemistry and temperature may also occur.
Animals often behave strangely shortly before an eruption like chickens not laying. This happened when Krakatoa (now Anak Krakatoa) erupted in 1883.
When the magma gets close to the surface, the gases dissolved in it start to come out, forming gases which help the magma rise further and erupt. If there is a lot of gas in the magma, it may explode as the gases expand. There may also be triggers like a landslide that uncaps the magma reservoir (like at Mt. St. Helens in 1980) or an interaction with groundwater that causes an explosion.
In some cases, yes. A volcanic eruption is often preceded by earthquakes with unique signatures. A volcano preparing to erupt may also bulge outward. In some cases a volcano may start venting steam, or more steam than usual. Sometimes small steam eruptions may occur as rising magma boils groundwater. This is a complicated matter however. In some cases a volcano may show signs of erupting, but nothing will come of it.
The timeframe for a stratovolcano to erupt can vary greatly depending on several factors such as geological conditions, magma composition, and the volcano's history. Some stratovolcanoes can go hundreds to thousands of years between eruptions, while others may erupt more frequently. Monitoring systems can give some warning signs before an eruption occurs, but pinpointing an exact timeline can be challenging.
It can be called an active, dormant or extinct volcano. An active volcano erupts regularly and frequently, however, it might not erupt at some times. A dormant volcano rarely erupts. Therefore, it does not erupt for most of the time. An extinct volcano does not erupt anymore.
The time it takes for a volcano to erupt can vary greatly. Some volcanoes may show signs of impending eruption for weeks or months, while others may erupt with little warning. It depends on factors such as the type of volcano, the amount of pressure building up, and the presence of monitoring systems.
Yes, volcanoes can become restless and erupt quickly after showing signs of increased activity. Some volcanic eruptions can occur with very little warning, while others may show signs of unrest for weeks or months before erupting. It ultimately depends on the specific volcano and its unique patterns of activity.

some say a volcano erupt
Some are now in Iceland.
There is no way to predict with certainty if or when Mount Krakatoa will erupt again. It is an active volcano, so there is always a possibility of it erupting in the future. Monitoring by volcanologists can provide some early warning signs, but eruptions can still occur with little warning.
The time it takes for a volcano to erupt can vary greatly depending on the specific volcano and its activity levels. Some volcanoes can erupt within hours or days of showing signs of activity, while others may take weeks, months, or even years to erupt. Monitoring systems are in place to track volcanic activity and provide warnings when an eruption is imminent.
As many as it wants. Some volcanoes erupt often, some infrequently
sometimes it does and some times it doesn't
Overheating some spaghetti sauce caused an eruption in the cooking class. The historical eruption of Mount Vesuvius destroyed the Greek city of Pompeii. A skin eruption should be kept clean to avoid infection.
