Before I start, if you wish to see the USGS earthquake map for this location and time period then please CLICK HERE. This one tremor event is composed of multiple reported "Other Events". That is how USGS is reporting most of these DLP-HFEs. Now these tremor events are for sure signifying the mass transport of magma along the mantle plume conduit, according to the hypocenters. Magma is likely splitting off from the mantle plume and heading into both the Mauna Loa and Middle East Rift Zone reservoirs. However, as of right now, the closer you get to the Lower East Rift Zone (LERZ) the greater the uplift is. My money is on the LERZ for being the next location of volcanic eruptions. That, or Mauna Loa really is next. Who knows!
If you wish to see my previous post about these events, which will contain much more information, please CLICK HERE. I will simply show some plots below of this one spasmodic tremor. Wait a second, spasmodic tremor? Now why would I call it that? It seems these DLP-HFEs (deep long period, high frequency events), as I used to call them, can be called spasmodic tremor. That is what I heard from one of the professionals in the earthquake discussion group I joined on Facebook. If you search "spasmodic tremor plots" on Google, you will find it is an exact replica of what is currently taking place under the Big Island of Hawaii.
IT IS OFFICIAL! I am no longer calling these events DLP-HFEs. I will now refer to them as spasmodic tremor for the rest of my research into these tremor episodes.
On May 23, 2019, we saw one very large spasmodic tremor. This will be shown below. It started at 5:58UTC on May 23 and lasted approximately 30 minutes. I will first show the helicorder plots from the 4 stations labeled on the map above. I will then show the correlation of the 4 stations in the seismic program WAVES and will then detail this event via my custom plots generated by the seismic program SWARM. This will officially now be known as spasmodic tremor.
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. If there are too many posts, don't forget about the archives below!
