Welcome to the exotic events page in the "Seismic Events" drop-down menu! This page will be much like all of the other seismic event pages. However, this page will show seismic data for "exotic" events. Some of the events within this page are also under the "Event Examples" page. Please check there first. Exotic seismic events can be nuclear explosions, meteor impacts or air bursts from meteors, sonic booms, building collapses, underground collapses, unknown events, etc... I will try my best to keep this page tidy and just show basic information and seismic plots. This page will always be added to as time moves forward so check back here every now and then to see if I have added something new! If there are any mistakes or if you would like to make any suggestions, please do not hesitate to email me.
I will show the USGS event page for any given event and will then show the seismic data. Be aware some seismic data is in slide show format, due to the amount of images for any given event, and some are not. I try my best to list all of the events below in order, with the most recent events at the top. That means if you don't see anything interesting at first you might have to scroll through the events. Trust me, there is some cool stuff here! All of the events below have been confirmed by USGS and their partners. The event pages you see were NOT generated by myself, but by USGS. The plots were created by myself using SWARM and data obtained from seismic stations through the IRIS and NCEDC databases. The USGS earthquake catalog assisted me in finding these "exotic" events. I hope you enjoy!

Although the USGS event page is shown above, there is much more information on that page than is shown here. Please CLICK HERE to visit the USGS event page for the crazy Michigan meteor of January 2018.
This nuclear explosion, conducted by the North Korean regime, was so strong that the vibrations were felt by seismic instruments all over the planet. Below are the plots for station MCID which resides in Idaho, right on the southwestern tip of Yellowstone National Park. Directly below the MCID plots is the nuclear explosion "collapse" event which occurred in the same location just 8 minutes later. This is most likely a large collapse of the cavity created by the nuclear blast.
This peculiar event was logged as an "experimental explosion" and occurred underwater off the coast of Florida, USA. It is currently unknown what experiment was taking place in this area, during this time period.
About 17 days prior to the event shown above, another "experimental" explosion occurred in the same area off the coast of Florida. It also occurred a couple times prior to this but if you really want to see the data for all of these events in this location, please emaile me. What kind of "experiment" was taking place? This text here will be updated if I ever find out what caused these "experimental" explosions.
The underground nuclear blast was so strong that it was detected on seismic stations thousands of miles way, including MCID in Idaho, USA.
This text is for the event directly below ONLY. Although USGS did not mark this event as a meteorite, this M4.2 event in Chelyabinsk, Russia occurred at the same exact time as the air burst and explosion of the infamous Chelyabinsk Meteor (even down to the second). It is unknown why this was not marked as a meteorite, but the source is undeniable. This event's data will be taken from station ARU in the II network which was the closest station. The vibration from the air burst took about 90 seconds to reach ARU. Again, the event below shows the data for the Chelyabinsk Meteor which struck Russia on February 15, 2013 at 3:20UTC.
This text here is for the event directly below ONLY. I know I already showed what a rock burst looks like earlier on this page, but the event below is extremely peculiar. Usually rock bursts occur in mines and never occur at magnitudes near a M6 earthquake. What caused a rock burst at the SE Indian Ridge in 2010? When I find out I will update this text. As usual I will show the USGS event page, the plots for the closest seismic station, and will also show the plots from MCID in Idaho, USA, since it detected this event as well.
