Tsunamis can be formed after certain underwater events take place. A tsunami can form after an underwater landslide, earthquake or volcanic eruption.
First volcanic eruptionVolcanologists have found old volcanic rocks in the cratons of most continents. Here's a brief list of places and ages:Canada: 3.5 to 2.8 billion yearsRhodesia (Zimbabwe): 3.4 billion yearsSouth Africa: 3.3 billion yearsWest Australia: 2.8 billion yearsWest Australia: 3.1 billion yearsThe last eruption took place in Chili.
Volcanoes seldom appear suddenly, out of nowhere. Most volcanic eruptions take place in volcanoes that already exist. They are generally quite well known, and thus, easily avoided by those who wish to avoid volcanic eruptions.
Another geologic event that could take place is a volcanic eruption, where molten rock, ash, and gases are expelled from a volcano onto the Earth's surface. This event can lead to the formation of new landforms and potentially pose risks to nearby communities due to lava flows, ash fall, and volcanic gases.
Flowers were often the first to grow back after a volcanic eruption due to their ability to quickly colonize disturbed areas. The nutrient-rich ash from the eruption provides an ideal environment for seed germination and plant growth. Additionally, many flowers have adapted to thrive in harsh conditions, allowing them to establish themselves rapidly in the aftermath of such events. Their fast reproductive cycles enable them to spread and take advantage of the newly available resources.
During a volcanic eruption, three key occurrences can take place: the expulsion of lava, which can flow down the sides of the volcano; the release of ash and volcanic gases, which can spread over large areas and affect air quality; and pyroclastic flows, which are fast-moving currents of hot gas and volcanic matter that can devastate anything in their path. These phenomena can significantly impact the surrounding environment and pose threats to nearby communities.
During a volcanic eruption, animals should try to find shelter in a safe location away from the volcanic activity. They should seek higher ground if possible to avoid potential lava flows or flooding caused by the eruption. It is important for animals to stay away from toxic gases and ash clouds, which can be harmful to their health.

The loudness of a volcano eruption is typically measured using a seismometer to record the seismic waves generated by the eruption. A volcanic explosivity index (VEI) is also often used to quantify the explosiveness of an eruption based on factors such as eruption column height and volume of material ejected. Additionally, infrasound sensors can be used to detect low-frequency sound waves produced by the eruption.
