I agree with this statement. Great argument and supporting evidence!!

Your information is correct, but I have to disagree. While earthquakes are dangerous, people can only be hurt by buildings and buildings can be built to withstand earthquakes. No building can withstand lava. Lava is not the only danger. Volcanoes spew toxic gases that spread for miles. Volcanoes destroy more buildings and harm more humans then earthquakes. http://volcanoes.usgs.gov/hazards/lava/

Earthquakes and volcanoes are both very dangerous and sometimes deadly. However, I believe volcanoes are the more perilous of the two. Volcanoes spew hot lava, rocks, and poisonous gas when they erupt. The hot lava with obliterate anything and anyone in its path. It can also change directions suddenly, and move faster than 40 miles/hour!! The flying rocks and debris will crush and kill anyone that’s left. The ash and gas could remain around for a year or more after it is done erupting, and spread for miles and miles. The extremely high levels of CO2 in the volcano can suffocate anyone around it. This is shown in a process called lake overturn, where CO2 rapidly rises to the surface of a lake and suffocates humans, livestock, and wildlife. This phenomenon is most likely caused by volcanic eruptions. Another danger of volcanoes is that some can grow and spread, making them even more dangerous. An example of this is the stratovolcano Nyiragongo in Africa. Veins of volcanic lava have spread underneath a nearby town and could erupt at any moment. These veins are also giving off CO2, and have the potential to kill many people. Volcanoes are very dangerous, and are much more deadly than earthquakes.
