The activity in Hawaii is far from over! For a few days there were extremely low rates of seismicity all across the Big Island of Hawaii. Then, all of a sudden, a strong M5.3 struck the Big Island and almost 2,000 people reported to USGS within hours that they felt this event. Although one would assume this M5.3 struck near Kilauea, it did not! Surprisingly, it struck just to the NE of a dormant volcano called Hualalai. Hualalai has not erupted since the 1800's but if this seismicity was related to a type of magma event, it is possible Hualalai could be recharging for a soon-coming eruption. That is not for sure, but it is possible. Also, just 6 hours or so after the M5.3, another strong deep long period, high frequency event struck near Pahala, Hawaii. If you follow my work, you know I am fascinated with them. In this post I will show some information and data pertaining to these two events.

Here we go once again! On March 30, 2019 more DLP-HF events occurred under the Big Island of Hawaii. These DLP-HF (deep long period, high frequency) events, as I like to call them, seem to be happening much more lately. They occur primarily between 30km and 50km in depth under Pahala, Hawaii and can last a great amount of time. What is causing these events? Mass amounts of magma flowing through the main conduit from the mantle plume to the volcanoes? I don't know and I won't pretend to know. I will simply show some data and I suggest, if you know how to analyze seismic data, to check these events out for yourself.

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.
