The new “Geologic map of the northeast flank of Mauna Loa volcano, Island of Hawaii,” the culmination of many years of work by Hawaiian Volcano Observatory geologists, was recently published by the U.S. Geological Survey. The work was spearheaded by
Field engineers at the U.S. Geological Survey Hawaiian Volcano Observatory recently completed a multi-year effort to upgrade a subset of seismic stations at the summit of Kilauea Volcano.
A diverse array of techniques is utilized to monitor volcanoes around the world, including those in Hawaii. These methods include tracking changes in the chemistry and volume of gases emitted from a volcano, recording earthquake activity, measuring changes in surface
Eruptions are not the only hazard created by volcanoes. They can create havoc millions of years after their fires have grown cold, because with time, their deposits can weaken to produce landslides. This happens because volcanic deposits are commonly rich
The lava delta at Kilauea Volcano’s Kamokuna ocean entry continues to grow.
Editor’s note: This week’s Volcano Watch was written by USGS Hawaiian Volcano Observatory geologist Don Swanson, who worked on Mount St. Helens before and after the 1980 eruption.
Seismology is often thought of as “earthquake science” because earthquakes — while not the only cause — are the most prolific producers of seisms, or earth shaking. The largest earthquakes ever recorded release many thousands of times more energy than
On June 13, 1950, Honolulu was suddenly blanketed by the thickest haze seen since recordkeeping began there in 1906. Interestingly, the haze was first noticed four days earlier at Johnston Island, 800 miles southwest of Oahu, and then on June
