Has Sunset Crater caused damage?
Sunset Crater, a basaltic cinder cone in the San Francisco Volcanic Field, Arizona, erupted in 1085 A.D. Colton saved the cone from severe damage by averting the attempt of a Hollywood movie company to blow it up in order to simulate an eruption.
What hazards does Sunset Crater have?
The seismograph at Sunset Crater Volcano will give a short- term warning of an impending event. Earthquakes can also create hazardous landslides and rockfalls. Unconsolidated material found on the slopes of Sunset Crater Volcano is especially susceptible to failure when the earth trembles.
Is Sunset Crater still active?
Local cinder cones are created by a one-time eruption event and are not known to erupt more than once. Sunset Crater Volcano erupted over 900 years ago, making it the youngest cinder cone in a field of over 600 volcanoes. It is now extinct and not anticipated to erupt again.
When was the last eruption of Sunset Crater?
Sunset Crater in northern Arizona is one of the youngest volcanoes in the USA. It is named for its brilliantly colored scoria deposits on the cone and only one of more than 550 vents of the vast San Francisco volcanic field. The last eruption took place sometime between about 1080 and 1150 AD.
Has Sunset Crater killed anyone?
No evidence has been found that people died as a direct result of the eruption, so it seems there was enough warning for people to evacuate from their homes. After the eruption, pithouses for miles around were burned and filled with cinders, and others were buried beneath the lava.
When was the last volcanic eruption in Arizona?
about 1,000 years ago
Our volcanic past The last major eruption was about 1,000 years ago at Sunset Crater, about 20 miles northeast of Flagstaff. About the same time, there was another eruption near the north rim of The Grand Canyon in the Uinkaret volcanic field.
What type of volcano is the Sunset Crater?
cinder cones
The San Francisco Volcanic Field Sunset Crater Volcano is one of around 600 cinder cones in the Flagstaff area. This is a region of intense volcanism that began around 3 million years ago with the formation of a lava dome called Bill Williams Mountain.

What caused Sunset Crater?
Sunset Crater is a colorful volcanic cone composed of lava fragments called cinders. It was created when molten rock spewed from a crack in the ground, high into the air, solidified, then fell back as cinders or ash. Over the next 200 years, the heavier debris accumulated around the vent creating the 1,000-foot cone.
How are cinders created?
Cinder cones form from ash and magma cinders–partly-burned, solid pieces of magma, that fall to the ground following a volcanic eruption. This type of eruption contains little lava, as the magma hardens and breaks into pieces during the explosion.
Is Mt Lemmon a volcano?
No volcano is found in or near Mount Lemmon, AZ.
How big was the eruption of Sunset Crater?
The Sunset Crater eruption produced a blanket of ash and lapilli covering an area of more than 2,100 square kilometers (810 sq mi) and forced the temporary abandonment of settlements of the local Sinagua people. The volcano has partially revegetated, with pines and wildflowers.
How did H’s Colton save Sunset Crater?
In the 1920’s, H.S. Colton saved the cone from severe damage by averting the attempt of a Hollywood movie company to blow it up in order to simulate an eruption. This led to the establishment of the Sunset Crater Volcano National Monument.
How did people interact with the Sunset Crater?
There is evidence of humans interacting with the volcano as it erupted – there are pieces of Sunset Crater scoria with impressions of corn kernels and husks. These “corn rocks” are believed to have been made when people placed ears of corn near hornitos, spattering vents that form above lava flows or tubes.
How old is the Sunset Crater in Arizona?
A lava field at the foothills of the crater, estimated to be about 1000 years old. Sunset Crater Volcano National Monument is a U.S. National Monument in the north-central part of the U.S. state of Arizona, created to protect Sunset Crater, a cinder cone within the San Francisco Volcanic Field.
