Mauna Loa is the largest active volcano on earth and makes up more than half of Hawai'i Island's land mass. Its last eruption was nearly 34 years ago, but over a longer time frame time. It’s erupted every 5 to 6 years with the potential to reach far flung parts of the island. As part of “Volcano Awareness Month,” scientists at Hawaiian Volcano Observatory are hosting workshops to inform the community. From Hawai'i Island, contributing reporter Sherry Bracken has more.

It’s been 33 years since Mauna Loa last erupted, but an alert level remains in place at the world’s largest active volcano. Scientists at Hawaiian Volcano Observatory raised the alert level two years ago. HPR Contributing Reporter Sherry Bracken says that although scientists say no eruption is imminent, they want Hawai'i Island residents to be aware of the likelihood of a future eruption.

Hawai'i Island’s Kīlauea Volcano gets a lot of attention with its two spectacular eruption locations. But the island’s dominant active volcano is also under close observation from scientists. We get details from HPR contributing reporter Sherry Bracken.

For Stargazer this week, we have a nice line-up of morning time planets to look for and a return visit to dwarf planet Ceres where NASA is coming up with some incredible new photos. Hear the report with HPR All Things Considered Host Dave Lawrence and Christopher Phillips.

For the first time in more than thirty years, scientists at the Hawaiian Volcano Observatory have raised the alert level for Mauna Loa.

The elevation from normal to advisory indicates the volcano is showing signs of activity that are greater than normal levels.  Seismic stations have recorded heightened levels of shallow, small magnitude earthquakes beneath the summit of the upper south-west rift zone.  Janet Babb is a Geologist with the U.S. Geological Survey.

  Although Kilauea is the most active volcano on Hawai'i Island right now, Mauna Loa is also still an active volcano. In  the last year, it has begun showing some changes that could indicate future activity.  Hawaii Island HPR's Sherry Bracken has more.
