In this simple #python script which uses the @obspy software, I have asked for a whole day's worth of data on staton IU.HNR on the #SolomonIslands following the magnitude 7 #earthquake at 02:03 UT (https://earthquake.usgs.gov/earthquakes/eventpage/us7000irfb/executive)
So more (15 minute) lines of #data appear as the day progresses. Still many #aftershocks of magnitude up to 5.2. It's amazing what you can get with just 12 lines of code. Data via #IRIS

This happened in the night my time: magnitude 7 #earthquake in the #SolomonIslands (2022-11-22Z02:03) Signal on station IU.CTAO (Charters Towers, Australia) Incredible #surfacewaves - it was quite a shallow event. Damage to buildings and power out (c.f. the Guardian: https://www.theguardian.com/world/2022/nov/22/tsunami-warning-after-70-magnitude-earthquake-near-solomon-islands)

There is quite an intensive #aftershock sequence following the #SolomonIslands #Earthquake This is a "mock helicorder plot" from the station IU.HNR (Honiara, Solomon Islands). The data is made freely available via #IRIS and is plotted using the free and open @obspy software. https://earthquake.usgs.gov/earthquakes/eventpage/us7000irfb/executive

According to posts on twitter, there are significant damages and at least 2 fatalities after a moderate magnitude M5.6 #earthquake in western Java island, Indonesia. Inland shallow fault rupture, close to towns, likely explain the destructions.

Magnitude 5.6 #earthquake on #Java #Indonesia about one hour ago (2022-11-2ZT06:21) a little south of #Jakarta. There are reports of damage. Signal on station GE.BBJI (Bungbulang, Garut, Java) courtesy of @geofon and displayed using @obspy software. I hope that damage and injuries are limited. https://earthquake.usgs.gov/earthquakes/eventpage/us7000ir9t/executive

So main #COP27 achievements are an as-yet-unfunded commitment to loss and damage and not quite backsliding on some of the commitments from COP26. Doesn’t really feel like we’re collectively meeting the moment, does it? https://www.theguardian.com/environment/2022/nov/20/cop27-climate-summit-egypt-key-outcomes

Without any binding commitments to rapidly and immediately reduce greenhouse gases, the world stands no chance to deliver on the 1,5°C limit, and by doing so minimising risks of uprooting the life supporting systems we all depend on and endangering countless human lives.
#COP27

Nov. 20, 1933: A M7.3 earthquake struck offshore Baffin Island, #Canada.
This is the largest known #earthquake along the passive margin (east/north coasts) of #NorthAmerica and the largest (known) earthquake north of the Arctic Circle.

A magnitude Mw6.9 #earthquake offshore south-central #Sumatra.

Mechanism and location suggest rupture on the shallow part of the #subduction #megathrust close to the trench (on the very shallow dipping fault plane). However, modelled depth of ~19km, if true, seems little too deep given the closeness with the trench (USGS gives same depth and mechanism). This means that we cannot exclude a rupture on the steep fault plane within the oceanic plate.

I never expected Musk to go to such great lengths to promote the fediverse.... but here we are.

So this is my first post on Mastodon.

Part of my work as a volcanologist with the Italian National Institute of Geophysics and Volcanology (Istituto Nazionale di Geofisica e Vulcanologia, INGV) is the real-time surveillance of seismic and volcanic activity in the volcanic areas of Sicily. This is done in 8-hour shifts in the Operations Room of the INGV seat in Catania, the Osservatorio Etneo. This is me making a stupid face during my latest shift, on 5 November 2022.

Today’s #Texas M5.4 #earthquake (approximate location as a purple blob) in the context of nearby #reinjection wells and other recent #earthquakes on a map from Tung et al. (2020)

Look closely at the center of this image. You probably noticed the bright spot in the center, the central protostar. But did you notice the dark band in front of it? That’s the protostar’s accretion disk, created as material swirls around it.

The material within this disk can sometimes clump up, forming the beginnings of planets. But the protostar will absorb many of these before they can mature.
