In addition to earthquakes, floods, and mudslides triggered by eruptions at Mount St. Helens, secondary events can include lahars (mudflows), pyroclastic flows, ash fall, and gas emissions. These events can impact surrounding areas, infrastructure, and ecosystems, posing hazards to human health and safety. Emergency response efforts typically involve monitoring, evacuation plans, and communication to mitigate risks and protect affected populations.
Mt Kilauea is a shield volcano in Hawaii that is typically associated with volcanic activity rather than issues like earthquakes, floods, mudslides, or lahars. However, eruptions on the volcano can lead to related hazards like lava flows and volcanic gases.
Earthquakes and volcanoes are hazards typically associated with convergent boundaries where tectonic plates collide. Mountains can also form at convergent boundaries due to the collision of plates. Trenches are associated with subduction zones at convergent boundaries where one plate is forced beneath another. Mudslides are not directly related to convergent boundaries.
Earthquakes themselves are natural disasters, and they can trigger secondary events such as tsunamis, landslides, and liquefaction. Volcanic eruptions can also be associated with earthquakes, especially in regions with active volcanic activity.
Volcanic activity does not result in aftershocks like earthquakes do. However, there can be secondary eruptions or explosions associated with a volcanic event that can occur in the days or weeks following the initial eruption.
The number of mudslides each year can vary significantly based on factors such as weather patterns, geography, and human activity. On average, thousands of mudslides occur globally, with some regions experiencing more frequent events due to heavy rainfall, earthquakes, or volcanic activity. For example, in the United States, the National Weather Service estimates that there are approximately 25 to 50 significant mudslides annually. However, comprehensive global statistics are challenging to compile due to varying reporting methods and regional definitions of what constitutes a mudslide.

Earthquakes, volcanoes, and tsunamis.
Earthquakes are usually associated with the shifting of tectonic plates beneath the Earth's surface. The sudden release of energy due to this shifting causes seismic waves to radiate outwards, resulting in ground shaking. Earthquakes can also be associated with volcanic activity or human activities such as mining or reservoir-induced seismicity.
Most seismic activities are associated with areas of active tectonism. So earthquakes occurs principally in such areas.
Mudslides commonly occur in areas with steep slopes and loose soil or rock, often in mountainous regions or areas that have experienced wildfires. Regions with heavy rainfall, snowmelt, or earthquake activity are also prone to mudslides.
Sound waves are not characteristic of earthquakes. Earthquakes are typically associated with seismological waves, such as primary (P) waves, secondary (S) waves, and surface waves, that travel through the Earth's crust. Sound waves, on the other hand, are mechanical waves that require a medium, like air, to travel through, and are not directly related to seismic activity.
The study of earthquakes is called seismology, while the study of volcanoes is called volcanology. Both fields involve understanding the processes and phenomena associated with seismic activity and volcanic eruptions.
There are three forms of earthquakes which are the convergent boundary, divergent boundary, and the transform fault. The earthquake waves may be in P-waves (primary) and in S-waves (secondary).
