Abstract/Description

Mapping Volcanic Eruptions of Modern Day Mount Kilauea using Remote Sensing.

Abstract

This research will be focused on mapping the volcanic activity of Mount Kilauea in Hawaii. Kilauea is a volcano that is 12,000 meters above sea level and takes up 14% of the land area of the big island, in other words, it is a huge volcano that has been continuously erupting for 30 years. These eruptions have drastically changed the landscape around it. Landsat 8 thermal infrared imagery will be used to assess and compare 3-5 different images from different dates of eruption from 2014 to the present day. Specific focuses will be on NDVI for land cover change, NDVI threshold for emissivity, and Stefan Boltzmann equation for studying radiative heat flux in the images. A supervised classification will be used to further assess land cover change and provide a simple way to look at how far the volcanic eruptions have reached into neighboring areas, including towns and infrastructure.
