Yellowstone Volcano On Map
The major features of the caldera measure about 34 by 45 miles 55 by 72 km. We don t exactly know.
Simplified Map Of Yellowstone Caldera
A second cycle concluded with the eruption of the much smaller mesa falls tuff around 1 3 million years ago.

. It also encompasses the entire lower half of the numeral eight. This crater is over 42 miles at its widest point. The usgs arm of yvo is also responsible for monitoring and reporting on volcanic activity in the intermountain west u s. Yellowstone national park covers some 3 472 square miles of land across three states in the northwest.The caldera and most of the park are located in the northwest corner of wyoming. The map also includes an outline approximating the crater left by the last major eruption of the yellowstone volcano called the yellowstone caldera. It encompasses all of the central plateau most of the hydro thermal areas in the park and a substantial portion of yellowstone lake. The 2450 km 3 588 mi 3 huckleberry ridge tuff erupted about 2 1 million years ago creating a large approximately 75 km 47 mi wide caldera and thick volcanic deposits.
The yellowstone caldera is a volcanic caldera and supervolcano in yellowstone national park in the western united states sometimes referred to as the yellowstone supervolcano. It is an irregular circular shape and is southwest of center in relation to the park as a whole. Map of the yellowstone caldera purple border with older calderas green border the last time the yellowstone supervolcano erupted was 640 000 years ago. The supervolcano would blanket the us in volcanic ash eruption maps accompanying the study suggest not one part of the us save the southernmost tips of florida.
This simple map outlines the extent of the yellowstone caldera as well as some basic physical features of the region. How old are yellowstone s large geysers. The yellowstone eruption area collapsed upon itself creating a sunken giant crater or caldera 1 500 square miles in area. Activity subsequently shifted to the present yellowstone plateau and culminated 640 000 years ago with the eruption of the 1000 3 km 240 mi 3 lava creek tuff and consequent formation of.
Yellowstone volcano is one of the world s biggest and most active supervolcano systems. Yellowstone volcano eruption simulations show an unexpected blast would produce ash fallout from the northwest us down to the southern tip of florida. Volcanic ash fallout of more than 39 4 inches one metre would blanket yellowstone s immediate vicinity in the states of wyoming montana and utah. When it did it left behind a caldera a landform created by the inward collapse of a volcano s peak.
It seems like. The yellowstone volcano observatory yvo is a consortium of nine state and federal agencies who provide timely monitoring and hazard assessment of volcanic hydrothermal and earthquake activity in the yellowstone plateau region. The yellowstone supervolcano last erupted about 640 000 years ago.
