I thought giving blood on Halloween would be scary, but Dr. Acula really put me at ease!

This week saw the return our seismometers from the glaciers of Iceland after 5 months of deployment.
The sensors recorded earthquakes around the Bárðarbunga caldera beneath the Vatnajokull glacier, allowing for a greater understanding of the volcano's interior.

At 9 AM on a Saturday, hundreds of runners gather to Leicester Victoria Park for #parkrun.

The start kicks off a seismic swarm of runners, releasing energy with every step. This creates a peak in ground displacement in our seismometers every Saturday morning.

Between May 2022 and Dec 2023, 35 of our seismometers were deployed across Zambia as part of the CuBES project.

Utilising shear-wave splitting, researchers were able to constrain lithospheric features from the Precambrian to Phanerozoic across the region.

A seismic section showing the #earthquake's travel time across the Earth is shown below, with the earthquake's location and the presented seismometers plotted on the map.

This was a significant earthquake, with seismometers on the other side of the globe detecting seismic motion.

A M7.5 #earthquake occurred within the Drake Passage (between South America and Antarctica) at 02:16:19 (UTC), detect on my @raspishake.bsky.social seismometer in Leicester, UK.

The earthquake was a strike slip earthquake, meaning a tsunami is highly unlikely.

Large earthquakes are followed by many smaller earthquakes nearby, called aftershocks. The rate of aftershocks decreases with time.

After a significant quake the USGS releases an aftershock forecast. Below is the aftershock forecast for the M8.8 earthquake off the coast of Russia. 1/ 🧪

Graph showing the number of earthquakes along the Y axis and time along the X axis. The graph shows the main shock and then a sloping curve showing the number of aftershocks decreasing with time.

Last night at 23:24:50 (UTC time), a M8.8 #earthquake rocked the Kamchatka Peninsula in eastern Russia. The event was detected by seismometers in our test bays, taking only 12 minutes to arrive.

This event was the largest since the 2011 M9.1 earthquake in NE Japan.

Part of Northern California (from the CA/OR border to Cape Mendicino) is now under a Tsunami Warning. The rest of California remains under a Tsunami Advisory.

The M8.8 Kamchatka earthquake can be seen here arriving at several @raspishake.bsky.social seismic stations across the globe.

At 23:24:50 (UTC time), a M8.8 #earthquake struck eastern Russia causing a tsunami that is crossing the Pacific. The event was detected on my @raspishake.bsky.social seismometer in Leicester, UK.

The #earthquake is the largest since the M9.1 earthquake that struck NE Japan in 2011.

In 2010, an increase in seismic activity at the Northern Volcanic Zone in Iceland led to a deployment of our seismometers. The seismicity was located in the mid/lower crust, which was attributed to the flow of dyke intrusions as they moved through the Earth.

Last year saw the return of Kasabian to Victoria Park, Leicester for their Summer Solstice II tour.

During the gig, our seismometers picked up the movement of the band and crowd, distinguishing the songs in the set list by their BPM.

First successful bat detection on my #πpistrelle bat detector in Leicester UK.
I believe (and I'm no expert) that the descending frequency from a high of 100 kHz to a long trail at 50 kHz is the chirp of a #pipistrelle, probably a common one. 🦇🦇🦇 #bat

M6.2 strike-slip #earthquake occurred near the island of Crete in Greece at 03:19:35 (UTC), detected on my @raspishake.bsky.social seismometer.

No major damage has been reported in the region.

Rare for this station, both the P and S wave arrivals can be seen in the unfiltered waveform.

M6.4 #earthquake occurred at 04:15:38 (UTC) beneath the Tonga Island Region in the SW Pacific. This was detected on the @raspishake.bsky.social seismic network.
The focus point (hypocenter) of this earthquake was deep at 243 km depth, which is not uncommon for the region.

M7.4 #earthquake at the southern tip of Argentina in the Drake Passage, detected on my @raspishake.bsky.social seismometer. A tsunami threat was reported, but has since been downgraded.
For some perspective, if the latitude was flipped, the location would be on the same latitude as Scotland.

Large earthquakes can be detected around the world. This animation from @earthscope.org
uses real seismic data to show the seismic waves from the M7.1 Tonga earthquake as they were detected by seismometers across North America.

The M7.0 #earthquake from the Tonga Island Region can be seen around the world on the @raspishake.bsky.social network.
The arrival of the seismic waves from the earthquake are displayed here on a seismic section, with the predicted phase arrivals overlaying the seismograms.

M7.0 #earthquake occurred at 2025-03-30 12:18:47 (UTC) in the Tonga Island Region, detected on my @raspishake.bsky.social seismometer in Leicester, UK.
An initial tsunami warning was declared, but it has since been dropped.

Significant damage has now been reported in Mandalay (Myanmar), with several building collapsed, with the #earthquake felt for a "long time" according to residents in the region.

The Myanmar #earthquakes can be seen in this seismic section from the @raspishake.bsky.social network. The M7.7 earthquake is plotted with the phase arrival times, with a M6.4 earthquake occurring shortly after in the same region being seen later (higher up) in the closest seismograms (left).
