Two largest marsquakes to date recorded from planet's far side
Phys.org ^ | APRIL 23, 2022 | Seismological Society of America

Posted on 04/23/2022 3:03:19 PM PDT by BenLurkin

The two marsquakes differ in some important ways. S0976a is characterized by only low frequency energy, like many of the quakes identified so far on the planet, while S1000a has a very broad frequency spectrum. "[S1000a] is a clear outlier in our catalog and will be key to our further understanding of Martian seismology," Horleston said.

S0976a is likely to have a much deeper origin than S1000a, she noted. "The latter event has a frequency spectrum much more like a family of events that we observe that have been modeled as shallow, crustal quakes, so this event may have occurred near the surface. S0976a looks like many of the events we have located to Cerberus Fossae—an area of extensive faulting—that have depths modeled to be around 50 kilometers or more and it is likely that this event has a similar, deep, source mechanism."

Compared to the rest of the seismic activity detected by InSight, the two new far-side quakes are true outliers, the researchers said.

"Not only are they the largest and most distant events by a considerable margin, S1000a has a spectrum and duration unlike any other event previously observed. They truly are remarkable events in the Martian seismic catalog," Horleston said.

I have no idea of what this means to an Earth long here in Texas

Any bets as to the cause being a large meteor strike?

I bet it was fracking. Danged Martian rednecks.

My first thought as well, but apparently these both occurred well under the surface.

Meanwhile the geniuses at the Seismological Society of America don’t bother giving us a clue as to what that would be on the richter scale. Useless information to 99.99999% of people here on this planet.

People are actually paid to do this?

Eggheads gotta work somehwere. Especially when it’s too hot to fish, too hot to golf, and too cold at home.

We need to see if it was caused by CLIMATE CHANGE on Earth! 🤓 The Dems will raise taxes for a study..

It is my excerpting to which you are taking excpetion. Elsewhere in the article:

“The seismometer placed on Mars by NASA’s InSight lander has recorded its two largest seismic events to date: a magnitude 4.2 and a magnitude 4.1 marsquake. The pair are the first recorded events to occur on the planet’s far side from the lander and are five times stronger than the previous largest event recorded.”

Silly me. I scanned the article and did a Ctrl+F search for “richter” LOL. Didn’t think to look for seismic.

So basically, it’s like living in California though I haven’t heard much about seismic activity in Cali lately. Maybe it’s just so normal, no one thinks or talks about it?

I live real close to the New Madrid fault. The same one that rung church bells in Massachusetts. I knew a lady several years ago that bought into random youtube stuff and some allegedly Navy guy said the big one was coming for this fault line and that everything West of here would drop into the ocean. She was living on a hill and couldn’t wait to have that ocean front property. Crazy shiot.

I can’t even get an accurate 7 day weather forecast. Who’s going to predict an earthquake? DARPA?

“Nope. Caused by the vaxxes”

Or Global warming

I thought tectonic activity on Mars was over. Can you get a marsquake without tectonic activity? Any chance they picked up a couple of meteorite strikes?

We had a 6.2 quake about four months ago but in a NorCal rural area. No one cared. Get a 3.3 in Los Angeles and it's headlines:

6.2 E quake off Petrolia
