Recent regional and teleseismic events recorded at the @geo3bcn-csic.bsky.social Educational Seismic Network in NE Spain @raspishake.bsky.social
Following the magnitude 8.8 Kamchatka earthquake, the Earth's normal modes are visible on broadband seismometers around the world, as here at the San Pablo (PAB) station in central Spain. The lowest mode, 0S2, shows that the Earth deforms every 52 minutes @geo3bcn-csic.bsky.social
On August 10, a massive landslide in Tracy Arm Fjord, Alaska, resulted in ground shaking recorded by seismic instruments around the world, as these in Spain, located at distances of 8,000 km aprox. Weak P waves arrive around 13:38 UTC, followed by S waves and surface waves.
Broad-band seismometers of the EPYSIM project in NE Spain have recorded the passage of surface seismic waves orbiting the Earth. At least five passages have been identified in each sense, meaning that seismic waves are still detected after traveling more than 200,000 km. @geo3bcn-csic.bsky.social
Els terratrèmols de magnitud 6.5 i 6.0 amb epicentre prop de l'illa de La Guadeloupe, enregistrats per les estacions de la Xarxa Sismica Educativa del @geo3bcn-csic.bsky.social
Last night magnitude 7.4 earthquake in the Philippines Islands, recorded by the seismometers of the @geo3bcn-csic.bsky.social Educational Seismic Network in NE Spain
Seismic record of ocean waves generated by Storm Harry, recorded at an EPYSIM project station near Tor, in the Baix Empordà area (NE Iberia) @geo3bcn-csic.bsky.social
After a major earthquake, surface seismic waves orbit the planet Earth. Their passage can be recorded by broadband seismometers, such as this station from the @geo3bcn-csic.bsky.social EPYSIM project
Comparing the amplitudes of the mag 8.8 and mag 7.4 Kamchatka earthquakes at a @GEO3BCN_CSIC broad-band seismic station located in NE Spain. Amplitudes for today's earthquake are almost 6 times larger.

Los efectos de las ondas generadas por el terremoto de Kamchatka, en Rusia, han sido detectadas en los sismógrafos de Toledo (España), más de 20 días después del seísmo.
