Well, it has been over 3 weeks since the last moderate to major spasmodic tremor swarm hit the Big Island of Hawaii. However, on June 25-26, 2019, volcanic spasmodic tremor has returned to the Big Island! It was not as strong as previous spasmodic tremor this year, however it was a resurgence nevertheless. I will show seismic plots from 4 select seismic stations across the Big Island and I will also include seismic audio for each event.

Well it has been more than a week since the last burst of spasmodic tremor, formerly called deep long period high frequency events by myself. Last night there was a very quick resurgence of spasmodic tremor, occurring in the same location and depths as many of the other ones have since January 2019. I will show a bunch of data pertaining to these events. Seismic audio is also included for the 5 spasmodic tremor events that occurred in Hawaii on June 1, 2019. Hope you enjoy!

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.
