I live in Los Angeles, CA and according to the Nathan World Map, we face a few natural hazards. The most prominent hazard in the area is living in a Zone 4 Earthquake area. Earthquakes happen regularly in Southern California and I have experienced quite a few, although none have been seriously threatening or damaging, the experience can still be scary. The area is also a Zone ¾ wildfire areas. It is very dry in Southern California, especially with recent drought and in the dry season there are frequent wildfires. Fortunately in an El Nino year, like this year, we experience a wetter season and have seen fewer wildfires. I think the Nathan Map has a fair representation of Los Angeles area hazards.
On the RDOE and EDIS map, I chose an event in Puebla, Mexico near Mexico City. On March 31, 2016 there was a volcanic eruption. Mile high Plumes were went up into the air and environmentalists warned of falling ash. Mexico’s National Center for Disaster Prevention raised the environmental alert level to the second degree out of three, meaning nearby residents should be prepared to evacuate.
This phenomenon would not occur in the Los Angeles area because there are not any volcanic region nearby. The nearest active volcanic field is in Northern California so it would take a massive eruption to affect the Southern California area. Volcanic eruptions in Mexico have caused tremors though and there is a lot of earthquake activity. However, the tectonic plates in Southern California Slide past each other instead of the submersive variety seen at eruption sites, therefore there is no risk of magma eruption.
This volcanic region is very near Mexico City, Mexico, which is a large city and could compare to the large population of Los Angeles. The active volcano is one of the world’s most dangerous. A mass evacuation of a large city like that is a big deal and would affect the Los Angeles Metro area in a similar capacity. Luckily, there are more warning signs for volcanic explosions than there are for Massive Earthquakes, so maybe being near a volcanic region is a safer location than living on a slide past earthquake system. If evacuations in such a large metro area were necessary I think that a similar solution to Hurricane Katrina traffic could be considered, where both sides of the highway are used for outbound traffic and incoming traffic is prohibited. This would be the only feasible way of getting such a large metro area out of the danger zone.
