Our transcription: The research currently underway has several goals.

Geologists hope to chart the underground structure of the vent and uncover clues to the explosive process.

They would further like to understand how heat escapes from the eruption deposit.

In order to do this indirect techniques are needed to survey the area because important evidence is buried too deep to examine directly.

The clever ways these surveys are designed illustrate how scientists have risen to the challenge of studying volcanoes.
