Which is more dangerous- an earthquake or a volcano? While earthquakes cause many disastrous incidents every year, volcanoes are at least a triple threat, which makes them ultimately more unfavorable. First, when volcanoes erupt, they explode hot magma which is treacherous and destroys everything in its flow path. Magma is also deleterious before it rises to the surface. Magma movement in the Earth’s mantle causes seismic activity, which can lead to to tremors, earthquakes, and tsunamis. (source: http://volcanoes.usgs.gov/activity/methods/seismic/ )This seismic activity is the second reason volcanic eruptions are more ruinous than earthquakes, and their ensuing results. Volcanic activity can also cause limnic eruption, or lake overturn, which is a rare but calamitous natural event. Limnic eruption is set off by the seismic activity of an active volcano and causes dissolved CO2 to billow out in huge clouds that suffocate humans, wildlife, and livestock. (source: http://www.design4disaster.org/disasters-2/natural-disasters/limnic-eruption/) ) ) These three dire natural occurrences caused by volcanic eruptions support the thought that they are more menacing than earthquakes.

volcanoes kill 600,000 people in one explosion and change global climates

earthquakes are very rare any way and only kill up to 600 people

also eruptions are harder to predict than earth quakes. also eruptions cause bigger tsunamis and they have more hazards like poisonous gases, having your skin burnt off and getting hit by hurtling rocks. also its much easier to survive an earthquake

although earthquakes are more frequent than volcanoes are more deadly one volcano eruption can kill more people than in three earthquakes and you can build houses which withstand earthquakes but not volcanoes.
