In this post I wanted to quickly show data and information pertaining to a certain event that happened at about 23:23UTC on Feb. 5, 2020. Please click the title of this post or "read more" to continue...

Quakes, spasmodic tremor, and continued deformation is the name of the game during these past two months. Spasmodic tremor continued to decline in December 2019 and January 2020. There was even an increase in swarming and M3+ earthquakes late-January. Please click the title of this post or "read more" to continue...
As for the past few months, spasmodic tremor has continued to decline. Regardless, we are still seeing a good sized spasmodic tremor event once per month. I will continue doing monthly spasmodic tremor updates until they increase or die off altogether. As usual, please click the title of this post or "read more" to continue... Spasmodic tremor continues to weaken and be replaced by high frequency earthquakes. As spasmodic tremor diminishes from its original stature, I believe high frequency earthquakes will continue to occur in swarms in the same location and depth as spasmodic tremor. This is the current pattern that is occurring and could change at any moment. Nevertheless, there were 4 spasmodic tremor events from Oct. 16 - Oct. 31.

There were only 4 spasmodic tremor events from Sept. 1 through Oct. 9, 2019. This is far less than the preceding months and could signal a weakening in the spasmodic tremor sequence we have been witnessing since Jan. 23, 2019. However, deep seismic activity seems to be increasing as the spasmodic tremor decreases. Could the tremor be in the process of being replaced by normal earthquakes? Only time will tell.

Hey guys! In this post I will show some quick data pertaining to an energetic swarm that broke out under Pahala, Hawaii, recent spasmodic tremor, and a deep M4.2 under the Loihi Seamount off the coast of Hawaii. Please click the title of this post or "read more" to continue...
Spasmodic Tremor, M4.5 and M3.2 near Hilo and Mauna Kea, and Growing Pond in Halema'uma'u Crater8/17/2019 Well, the Big Island of Hawaii never ceases to amaze. Not only are the wildlife and plants abundant in diversity, but so are the volcanoes! Many different aspects of volcanic activity continue to take place under, and on, the Big Island of Hawaii.
Spasmodic tremor continues sporadically, though rates seem to have dropped over the past several weeks. This does occur from time to time and magma continues to pour into the Mauna Loa summit, Kilauea summit, and Kilauea East Rift Zone reservoirs. There were also two earthquakes I will quickly mention in this post: a very strange M4.5 in Hilo Bay and a M3.2 under Mauna Kea. Also, if you haven't heard, a pond/lake is growing at the bottom of Halema'uma'u Crater inside of Kilauea Caldera. It is not a lava lake, but in fact a lake or pond of water. It was discovered on July 25, 2019 and was originally thought to be rain water. However, recent studies indicate that the pond is constantly growing and that recent rainfall has been minimal. Basically, it appears that groundwater is intruding into the crater, seeing that rainfall has been insufficient to create a constantly growing pond. Regardless, either groundwater or rainfall could be the cause. Either could be true, but the research done by HVO/USGS points more favorably toward groundwater. This could cause explosive eruptions in the near future if certain conditions have been met. And according to USGS/HVO, this type of situation has occurred at Kilauea before.

Also, earthquakes continue to slowly increase at Kilauea and Mauna Loa, with magnitudes seeing a sharp rise just since July 21, 2019. In this post I will show the usual seismic data and audio to recent spasmodic tremor events. Afterward, I will show plots of the largest earthquakes on the Big Island we have seen as of late.

Sometimes it doesn't occur for almost a week, however it seems to always return. Will we continue to see these until the next eruption in Hawaii (whenever that may be)? I think it is likely. As usual, please click the title of this post or "read more" to continue...
Hey guys! In this post I am going to show the usual seismic plots and audio associated with the spasmodic tremor events in Hawaii for July 4-5, 2019. I will also detail a reminder about what spasmodic tremor is and what it is likely caused by in Hawaii. As usual, please click the title of this post or "read more" to continue...

About
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. Archives
