Tiltmeters: Essential Tools for Volcano Monitoring

Tiltmeters, such as the water tube tiltmeter and electronic tiltmeters, have been crucial instruments in monitoring volcanic activity and studying volcano behavior. The continuous recording of tilt data has provided valuable insights into the inflation and deflation cycles of volcanoes, as well as changes in magma accumulation. By analyzing past records, scientists can make forecasts about future volcanic behavior and gain a better understanding of the plumbing systems of volcanoes like Kīlauea.

"Century-Long Importance of Tilt Measurements in Volcano Monitoring"

Tilt measurements have been crucial for monitoring and understanding volcano behavior for over a century. The Hawaiian Volcano Observatory (HVO) has been collecting tilt data since the early 1900s, initially using seismometers and later developing water tube tiltmeters and electronic tiltmeters. Continuous records of tilt have revealed cycles of inflation and deflation between eruptions, providing insights into magma chamber activity. Recent tilt records at Kīlauea's summit resemble those from the 1950s-1970s, indicating similarities in the volcano's behavior before the 2018 eruption. This historical data helps scientists make forecasts and test hypotheses about future volcanic activity.

Using Ocean Noise to Monitor Kīlauea Volcano

Scientists at the Hawaiian Volcano Observatory are using ocean noise velocity as a tool to monitor volcanic activity at Kīlauea volcano. Changes in the velocity of ocean noise signals can indicate the opening and closing of fracture systems caused by magma movement beneath the surface. By analyzing these velocity changes, scientists can gain insights into the behavior of the volcano and potentially forecast volcanic activity. This technique is being developed for real-time monitoring at Kīlauea and Mauna Loa volcanoes.

Using Lasers to Predict Volcanic Eruptions

Researchers have developed a new method using laser technology to analyze the chemical composition of erupted magma from volcanoes. By isolating the melt signal and analyzing it with mass spectrometry, this method provides a faster and more detailed measure of melt chemistry and its evolution over time. The study focused on the 2021 eruption at La Palma in the Canary Islands and found variations in lava chemistry linked to changes in earthquakes, sulfur dioxide emissions, eruption style, and hazards. This method could help improve monitoring and forecasting of volcanic eruptions, providing valuable insights into why they start and when they will end.
