If you were around the Island of Hawaii — or even other Hawaiian Islands, or Guam — between May and August of 2018, you likely know that Kilauea’s lower East Rift Zone eruption released a lot of sulfur dioxide (SO2). But how much is a lot?

Underwood Farms, who produced all the jalapeno peppers for the famous Huy Fong Srirarcha for 28 years, now has a line of their own line of sauces.

The past two years of “Volcano Watch” articles from late May focused on commemorating the 49th and 50th anniversaries of the Mauna Ulu eruption. However, the end of May has several other notable Kilauea eruption beginnings, changes, and endings. Here we reflect on some selected anniversaries spanning 1823–2018.

It takes a village to run a volcano observatory. The position of Deputy Scientist-in-Charge (DSIC), once called Operations Manager but always known as the right hand to the Scientist-in-Charge, has long been key to the Hawaiian Volcano Observatory’s success, especially as technology has advanced and staff size increased. Continuing in the tradition of skilled and dedicated leaders including Reggie Okamura, his brother Arnold Okamura, and recently retired Steve Brantley, HVO is proud to welcome David Phillips to the team.

The mission of the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) is “to monitor, investigate, and assess hazards from active volcanoes and earthquakes in Hawaii, and communicate results of this work to the public, emergency managers, and scientific community.”
