first smoke then top blows and magma leeks out
not sure
They detect volcano's by using seismographs.
High-precision GPS can be used to detect shifts in the ground on and near a volcano. This can be used to infer the underground movement of magma, which can help in predicting an eruption.
Yes. A volcanic eruption is often preceded by earthquakes and steam coming from the volcano. Sensitive instruments can detect small changes in elevation as molten rock moves underground. Large volcanic eruptions are often preceded by a series of smaller ones.
They may infer that the volcano has become more active - an increase in seismicity (an increase in the number of earthquakes) may be caused by the movement of magma into a high level magma chamber near the earth's surface, causing an increase in the magma pressure which can cause fracturing of the surrounding rock mass. This may be a warning sign of an impending volcanic eruption.
The arenal volcano is a cindercone volcano not a composite.
A tilt meter is an instrument that helps scientists detect small changes in a volcano's slope. This can help scientists figure out when a volcano will erupt. hehehe cherry poo bum. hehehe
Animals have much much better developed senses that humans do. They detect volcanoes and earthquakes by feeling minor vibrations in the ground

A tilt meter is often used on volcanoes. they measure the angle of the mountain/volcano. A basic tilt meter is a tub with some water in it and as the mountain gets taller the water moves this is marked. Most modern tilt meters are automatic and send the information my radio.
A Strato volcano or a composite volcano.
No. It is a composite volcano.
creating bomb shelters would protect people in cover from lava and having tilimeters which would detect when the volcano swells up as the magma rises. also boreholes would help and having an education on evacuation during a volcano or when one is about to occur. i hope this helps anyone for homework or just interested :)
