This is the tephra database for the Mono-Inyo Craters chain, a zone of
active volcanism that extends from Mammoth Mountain and Long Valley caldera in the south to the
islands of Mono Lake in the north. Within these web pages, we sometimes refer
to this as the Mammoth-Mono volcanic zone (MMVZ).
You can view the information in the database in tabular, graphical or map
format. Eventually, the database will consist of a number of tables that can be used by
researchers. The database is currently in the early (alpha) stage of development
as we gather data and develop web-based tools to present it.
One of our main goals is to provide a compilation of all
previous tephrochronological and geochronological studies for the chain.
Some of our other objectives:
Compile all of the information available for the proximal Mono and Inyo Craters
tephra, pyroclastic deposits, flows, and domes
Integrate data for distal tephra with proximal
Remove data inhomogeneities and correct data that have been shown
to be unreliable
Integrate dynamic mapping and graphing capabilities with advanced database
searching and querying
Provide data that can be used to study past eruptive patterns and provide insight about the possibility
of future eruptions
