Typical Eruption: (type your description below) – you may include an eruption map with citation (URL)

My volcano is a shield volcano. It is flat and very wide in shape. It has basaltic lava. The caldera is coved with over with dozens of tiny vents that erupt along a circular 4-km diameter fracture system. Somewhere on the volcano there was a fracture that is currently active, that releases basaltic magma, into the lava river at the base of the volcano.

Hazards: (type your description below):

The last eruption that this volcano had was in 2008. So this Volcano is very active. So people need to be cautious. There are very bad hazards, this volcano releases lots of long term vigorous gas admissions. It causes health problems and very bad air for crops. Also the type of lava could potently burn the city. For now the lava river is containing the lava for now. But once a river gets to full, it overflows.

The last eruption from Popcatepetl, is from the beginning of the year and the eruption is still ongoing to this day. The eruption is still on-going and very dangerous. The typical eruption from this volcano is that it just smokes often. But when it actually erupts, it’s a huge explosion. The mixture of dacite and basaltic andesite makes this volcano expload.
The dacite and basaltic andesite makes the volcano and the magma make a huge blast.

Hazards: (type your description below)
The hazards of Popcatepetl; Popcatepetl is surrounded by 3 more volcanos, which isn’t the best so the could all explode at one time. Also Popcatepetl is about a mile and a half away from mexico city. Which is very bad for the people inside the city and outside of the city. And not to say that if the volcanoes explode then Mexico City could be burnt to the ground with lava.

Typical Eruption: My geological setting is usually high in silica and explosive, so my volcano reflects it’s setting by being explosive. It has
andesite rocks and dacite rocks, which are typical in an explosive volcano. I’m on a convergent boundary which are created when plates crash together. I have a stratovolcano. My volcano is very explosive, in fact, most volcanoes on a convergent boundary are extremely explosive.

Hazards:. If, on the off chance it does erupt (this is unlikely as it’s dead…) there is a chance of lahars because of the glaciers on my volcano. People have also set up many agricultural plots one the east side of the mountain, so if it did suddenly decide to erupt, not only would the crops be destroyed, but people who lived on the sides, or tended to the crops would also be caught. There are many major cities in the vicinity of the mountain, and they too may be caught in it’s deadly rampage.

Typical Eruption: (type your description below) – you may include an eruption map with citation (URL)
The summit of Santa Ana (also known as Ilamatepec) has four nested craters, the innermost crater containing a small crater lake. This lake is called Lake Coatepegue, a popular recreation area, is at its eastern foot. There have been numerous historical eruptions since the 1500s, both at the summit and from cinder cones on the lower flanks. Its In October, 2005, the volcano erupted. It killed at least two people, injuring seven people, forcing many to flee their villages. The volcano reportedly discarded rocks for over 1.5 km (1 mile) with rocks the size of cars, also flood of boiling mud and water. The most resent one before that was 1904. The volcano produced a series of eruptions consisting of small explosions, gas emissions, and low or moderate seismic activity.

Hazards: (type your description below)
The city of Santa Ana lies at the foot of the northeastern slope of the volcano. Santa Ana’s eruption produced something else also: sulfur dioxide. The gas can inflame the eyes, skin, and upper respiratory tract. It also leads to acid rain and volcanic smog.
