Between March 27 and March 28, 2019, three extremely odd seismic events were detected on virtually every seismic station across the Big Island of Hawaii. They are emergent, meaning they slowly build, they primarily occur between 30km and 50km in depth, they travel quite far compared to their relatively low amplitudes, they carry mid to high range frequencies and can last anywhere from 15 minutes to 1 hour.

On March 13, 2019, a very strong M5.5 earthquake struck just to the SE of the infamous Kilauea Caldera volcano on the Big Island of Hawaii. A great many people felt this event and, as you will see in a bit, this was the largest earthquake to strike the Big Island since the volcanic eruptions calmed in early-August 2018.

This blog is specifically for activity that occurs in Hawaii. In light of 2018's eruptions on the Big Island, I felt it necessary to have a section entirely devoted to events in Hawaii. I now mostly use this blog to update people on volcanic spasmodic tremor which occurs deep within the mantle plume conduit(s) under Pahala, HI. Don't know what spasmodic tremor is? Don't fret! Simply go to the Hawaii menu and click the page about Hawaii Spasmodic Tremor.
