There’s a new predictive earthquake app circling right now called Terra Watch! Three years ago, this concept was supposed to be only educational, but it’s evolved to become highly predictive. All of the information on this app was taken from preexisting texts and well-respected websites like USGS.
I was able to test out this app for myself in its early development, and it managed to predict several major Philippine and Japanese earthquakes within last year.
So far, Terra Watch is only available on Android, but it has plans to further expand to other app stores in the future. The developers are also planning to add a news feature!!
If you could show your support by visiting and following their Facebook page, it would be greatly appreciated!

I was able to test out this app in its early development, and it managed to predict several major Philippine and Japanese earthquakes within last year with consistent accuracy.
So far, Terra Watch is only available on Android, but it has plans to expand to Apple store and other app stores in the future. The developers are also planning to add a news feature as well!

unfortunately i am the friend that always has weird homework. “sorry i cant hangout i have 28 jars of soil due at 11:59” like who the fuck even says that
The exposure represents a pegmatite body developed within Mansehra Granite.
2) Host Rock
The surrounding rock is Mansehra Granite, characterized by coarse-grained quartz and feldspar assemblage.
3) Quartz
Quartz appears milky to grey, coarse-grained, and fractured. It occurs both as pegmatitic crystals and within the granitic matrix.
4) Feldspar (Soda Feldspar – Albite)
Whitish albite feldspar crystals are visible. Partial alteration is observed near the shear zone.
5) Microcline (K-Feldspar)
Pinkish to creamy microcline crystals are present. Exhibits coarse pegmatitic texture, indicating slow crystallization.
6) Meta-Granite
Granite shows shearing and deformation, locally transformed into meta-granite. Minerals display fractured and crushed textures.
7) Shear Zone
A well-defined shear zone cuts through both the pegmatite and host granite. Marked by crushed grains, brecciation, and enhanced permeability.
8) Iron Oxide / Limonite Staining
Reddish-brown to yellow staining is observed along fractures. Indicates oxidation and hydrothermal fluid movement.
9) Structural Control
Shearing has controlled pegmatite emplacement and mineral alteration. Acts as a pathway for hydrothermal fluids.
10) Economic Significance
Pegmatite and shear zones are favorable for feldspar, quartz, and associated industrial minerals. Represents an important target for feldspar mining and exploration.
How is salt tectonics affected by salt rheology, rift tectonics, and sedimentation rates? ⚒️🧂
In this new article of Zhichen Wang, we present cross-scale geodynamic models bridging lithosphere deformation, evaporite flow and surface processes: https://lnkd.in/dbP2ppP4
My favourite highlight: oceanward translation velocity of post‐salt sediments is highly dynamic. It rapidly increases to peak values during approximately 1 million years before slowing over tens of millions of years as the evaporite layer thins and welds onto the underlying syn‐rift sediments.
The models elucidate the formation of key salt tectonic structures: turtle anticlines in the extensional domain, irregularly spaced collapsed diapirs in the translational domain, and complex diapir structures in the contractional domain. We show how asymmetric minibasins in the translational and compressional domains interact with adjacent diapirs, forming highly upturned and overturned strata.

Hello! For this post, I’m going to be talking about a glacial period, known as Pulse-1a. This was a period in geologic history that occurred around 21,000-14,600 years ago. This time period was originally discovered through coral records back in 1989 on the island of Barbados in the Caribbean.
This time period is so unique because in a very short frame of time, sea levels rose about 120 meters, about 4 meters per century, which is a very rare occurrence. Since then, many scientists have debated how global sea level could have risen to such lengths.
ALT
The main theory is that this meltwater came from retreating ice sheets. During this time, temperatures were rising. Prior to, a portion of the world had been covered by ice sheets, a well known ice sheet being the Laurentide ice sheet, which covered Canada completely and parts of America. Global temperatures were rising, particularly around 14,700 years ago, known as the Bolling-Allerod period, a time of abrupt warming. Not too long before, a Heinrick event occurred, 16,000-17,000 years ago, which also caused global temperatures to spike. This caused ice sheets to melt, particularly the Laurentide ice sheet, which is what caused such a great rise in sea levels.
ALT
However, there are some problems with this theory. The Bolling-Allerod period was more at the end of 1A, so it may not account for the time before when global sea levels were still rising. The same goes for the Heinrich event. There are a few other prominent theories, with some scientists believing that the source could have come from the Southern Hemisphere, instead of just the Northern Hemisphere, from the Laurentide ice sheet. Some also believe that the meltwater may have come from the Antarctic region, using glacial isostatic adjustment. However, there is still not enough evidence to fully prove any theory. Due to constraints with geologic time frames, no method currently has been enough to fully support these theories.
Various methods have been used to find the source of the meltwater. Geologists have derived mathematical equations to find relative sea levels to find the source. Many have also used geophysical modeling to reconstruct past sea levels of 1a. However, more research is needed to conclude what the true source is. However, there is still not enough evidence to fully prove any theory. Due to how limited the scientific methods are, there’s still research being done on this event today, and many geologists are still trying to figure out the source of meltwater. Only time will tell what the true cause is.
