The M8.7 aftershocks are distributed on a ~ 350-km long x 100 km wide area.
But actually the seismic crisis bagan on July 20 in #Kamtchatka. The foreshock sequence was concentrated on the north-east end of the rupture.
#Tsunami

Magnitude 8.7 #earthquake in Kamchatka, following a M7.4 last week - may be largest earthquake since 2011, 8th largest on record globally, #tsunami warning in place for US west coast and Canada - the historic 1952 M9 closely caused a destructive tsunami across the Pacific

Pyroclastic flows at Etna have been confirmed by INGV ⚒️🌋

On Italy’s Republic Day, Etna isn’t holding back 🌋🇮🇹 Activity started with mild Strombolian explosions that quickly intensified. A small lava flow made its way down the Valle del Bove. A particularly remarkable event just occurred: part of the Southeast Crater collapsed, triggering a PDC

🌡️ Ce samedi 5 avril à Paris, la température a atteint près de 26°C faisant de la ville la capitale la plus chaude en Europe. Par le passé, les 26 °C ont déjà été atteints à la station plus tôt dans l’année, le 31 mars 2021, ou encore le 3 avril 1946.

🌀Situation post-cyclone #Garance. Grâce à la forte mobilisation des équipes de l’OVPF-IPGP, l’observatoire a de nouveau le contact avec 65% de ses stations sur le terrain (contre 15% à la fin du cyclone).
L'OVPF-IPGP reste mobilisé pour remettre en état ce réseau le plus rapidement possible.

Bonjour,
Veuillez trouver ci-dessous le lien vers le bulletin mensuel de l’Observatoire Volcanologique et Sismologique de Guadeloupe (OVSG-IPGP) concernant l’activité volcanique de la Soufrière de Guadeloupe et la sismicité régionale pour le mois de Janvier 2025.

Moment magnitudes and corner frequencies calculated for 437 events from the Santorini crisis (Ml>3.5, Jan 24 - Feb 13) using SourceSpec. Big thanks to the EIDA node of the National Observatory of Athens for keeping their services online during this critical period.

The latest events (white dots) seem to be concentrated at the north-eastern end of the swarm.
#Santorini #Amorgos

Hi Seismo-Bluesky! I decided to test a pipeline with SeisBench, PyOcto, NonLinLoc, and HypoDD on the Santorini sequence. The level of activity (>4,500 events) is truly stunning! There are repeated bursts migrating backwards and forwards, spreading outwards from a narrow, almost linear channel.

Some of you were waiting for it: Here's our new data visualisation of the earthquakes near #Santorini, provided by our colleague Marius Paul Isken, and located with pyrocko/qseek. It includes yesterday's quakes and starts January 29. Marius included a nice twist, so to speak. Wait for it.

The seismic crisis between #Santorini and #Amorgos has been slowing down a bit during the last 24h and shows a slight migration toward the NE.

Updated version of the seismic activity in the Cyclades Islands, and the Gutenberg-Richter law, with 1022 earthquakes since 27th January. Please refer to the Greek authorities for more information, stay safe.
