Probably directly relevant to today’s M6.1 earthquake near Duzce: a map of earthquakes along the North #Anatolian #fault, where in 1999 the Izmit M7.5 #earthquake in August was followed by a M7.2 event near #Duzce a few months later. Both events were devastating, but much larger than today’s #quake.
Mwp6.1 #earthquake Baja California, Mexico 2022.11.22-16:39UTC http://early-est.alomax.net
Somewhat unusual location for an M6 earthquake, clearly to the southwest of the main San Andreas and Gulf of California plate boundary faults.
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

First-motion mechanism (constrained by steeply down-going energy) shows some strike uncertainty (tiny white and grey dots) but is neutral on the question of "normal" or "reverse" - probably the waveform-based mechanisms are too, if uncertainty taken into account. http://alomax.free.fr/projects/early-est/events/hypo.1669082591674.html
What does thawing #permafrost look like? Here's an example from a palsa mire in northern Norway: The permafrost in these peat mounds is thawing, due to #climate change, at which point they collapse. The peat gets submerged, and microorganisms convert soil carbon into #methane – a powerful greenhouse gas. But also: mosses and sedges begin to grow, which again store #carbon. At the University of Oslo, we are studying how this may act as a potential climate tipping point.

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
Earthquake Disaster
@RobinLacassin
Seems to be very high impact for an M5.5 #earthquake
https://www.bbc.com/news/world-asia-63700629
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.
