“May Day is Lei Day in Hawaii,” so the song tells us.

Did you go fishing along the coastline, caught fish but didn’t know the name of the fish, or how to clean or cook the fish?

The production of maps to track the progress of ongoing eruptions has long been part of the USGS Hawaiian Volcano Observatory mission to inform the public about volcanic hazards in Hawaii. The methods used to collect, interpret, and disseminate map data have been evolving ever since HVO’s founding in 1912, and a digital tool newly available to the public continues that legacy of innovation.

Kohanaiki, also known as Pine Trees, was bustling Saturday with families attending the 26th annual Surf for the Earth and Beach Clean Up.

Earth’s magnetic field surrounds us every second of the day, everywhere on the planet. Anyone who has picked up a pocket compass and seen the magnetic needle quickly align itself has seen the action of this ever-present invisible field. But can we harness the magnetic field to forecast volcanic activity? Emerging technology in the field of “quantum” science may aid us in doing so.

Make plans to attend the 11th annual Big Island Chocolate Festival held from April 25 to 27 at the Waikoloa Beach Marriott Resort &Spa.

The Island of Hawai‘i is one of the most seismically active regions in the world. In the last five years, an average of 600-1200 earthquakes per week have been detected by the USGS Hawaiian Volcano Observatory. This regular rumble of activity across the island can be used to our advantage to assess the hazards that Kilauea and Mauna Loa volcanoes represent.
