Data Processing Methods for 3D Seismic Imaging of Subsurface Volcanoes: Applications to the Tarim Flood Basalt
Published on: August 7, 2017
Summary
Stratospheric dust from the Fuego Volcano eruption spread across North America and Puerto Rico in late 1974. This volcanic dust caused unique striated twilight glows observed in New England and other locations.
Area of Science:
- Atmospheric Science
- Volcanology
- Photometry
Background:
- Striated twilight glows were observed in New England starting November 26, 1974.
- These phenomena indicated the dispersal of stratospheric dust previously noted over Arizona.
- Similar observations were made in New Mexico and Florida.
Purpose of the Study:
- To document and analyze the spread of stratospheric dust.
- To correlate twilight observations with volcanic activity.
- To measure previously unrecorded twilight features.
Main Methods:
- Photometric measurements of twilight phenomena.
- Analysis of observational data from multiple locations (New England, Arizona, New Mexico, Florida, Puerto Rico).
- Correlation of atmospheric observations with volcanic eruption reports.
Main Results:
- Striated twilight glows were observed across widespread locations, indicating significant stratospheric dust dispersal.
- Twilight observations in Puerto Rico revealed novel features.
- Photometric data confirmed the presence and spread of volcanic dust.
Conclusions:
- The Fuego Volcano eruptions in Guatemala (October 13-23, 1974) were identified as the source of the stratospheric dust.
- The observed twilight glows were a direct result of volcanic stratospheric dust.
- The study highlights the far-reaching atmospheric impact of major volcanic eruptions.

01:02Flame Photometry: Overview
Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...
01:16Flame Photometry: Lab
In a flame photometer, when a solution like potassium chloride is aspirated into the flame, the solvent evaporates, leaving behind dehydrated salt. This salt dissociates into free gaseous atoms in their ground state. Some of these atoms absorb energy from the flame, leading to their excitation. The excited atoms return to the ground state, emitting photons at characteristic wavelengths. Because only electronic transitions are involved, the resulting emission lines are very narrow. The intensity...
01:20Sulfur Assimilation
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to become...
01:22The Sulfur Cycle
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...
02:45Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

01:10Volatilization
Volatilization gravimetry is an analytical technique that measures the mass lost due to the volatilization of the substance. This technique is used to estimate the amount of volatile material in a sample. To perform this method, heat a known amount of the sample to a high temperature in a crucible or other suitable vessel. The volatile substance in the sample evaporates, and the vapor is completely expelled from the crucible either by heating the sample or bubbling a stream of inert gas through...
