Why are there so many volcanoes in the Mediterranean and the western United States in August?

1. Climate issues In 2020, temperatures in California and even the entire West Coast of the United States were unusually high in August. For example, August in California became the hottest August on record. In addition to high temperatures, there is also a dry climate, and some places have even reached the point of "severe drought." In addition, thunderstorms in California have been particularly severe this year. For example, in August in San Francisco, there was a thunderstorm in the surrounding areas, with more than 10,000 lightning strikes and more than 300 fires. Three wildfires around San Francisco, California were all caused by lightning. 2. Human factors: On the one hand, many activities of people in the wild may inadvertently trigger wildfires. Many highways in the United States are close to patches of woods. If a driver throws away a cigarette butt, it may cause a fire. In addition, many young people in California may shoot fireworks into the sky during parties, and sparks may also fall on dry and flammable plants, eventually causing wildfires. On the other hand, more and more residents in California are moving to the suburbs. In order to ensure the smooth flow of current services, such as electric services, more and more people need to pass through the woods. If there is a problem with the electric equipment, it is likely to cause a fire. 3. Natural causes The California Fire Department has actually been trying to suppress wildfires for more than a hundred years. However, wildfires are actually a natural phenomenon. As time goes by without wildfires, more and more dead plants will dry out and accumulate in the forest, forming flammable materials. Therefore, once a spark appears, it is more likely to turn into a large-scale wildfire.
