Significant magnitude 5.0 quake hits 116 km northwest of Mendoza, Argentina in the morning ![5.0 quake 8 Mar 9:48 am (GMT -3)]()
5.0 quake 8 Mar 9:48 am (GMT -3)
An earthquake of magnitude 5.0 occurred only 9 minutes ago 116 km northwest of Mendoza, Argentina, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at an intermediate depth of 98 km beneath the epicenter near Mendoza, Departamento de Guaymallén, Argentina, in the morning on Monday 8 March 2021 at 9:48 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.7 earthquake.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Los Andes (pop. 56,900) located 100 km from the epicenter, Calingasta (pop. 8,200) 107 km away, and Mendoza (pop. 876,900) 116 km away.

Los Penitentes / Moderate shaking (MMI V)
: Estamos en alta montaña muy cerca del epicentro. Desde anoche se sentia un ruido extraño que no podiamos identificar | 13 users found this interesting.
- Los ruidos provenian del cielo y de la tierra como un zumbido desde aproximadamente 9 hs antes. Estaba a 57 km en línea recta del epicentro.
- Tal vez como algo rompiéndose o como un tren por debajo? Si era ruido como de ruptura puede estar asociado a cambios bruscos de temperatura o a quiebres de roca producidos en el interior de Montes o montañas, lo que se denomina el parto de los montes un fenómeno muy aparatoso con mucho ruido asociado a fenomenos findelmundologicos que suele provocar hundimientos, por el contrario si fue ruido como de tren o algo pesado pasando en dirección a alguna parte se podría tratar de un sismo de cono, se produce en casos de ruptura de sellos el transvasije de agua, rocas y lodo entre dos secciones del cono con el consiguiente arrastre de material rocoso lo que produce un ruido característico
- ¿Fue un ruido extraño en la tierra o en el cielo o? ¿Un estruendo, como un tren o un musical? Thank you
Viña del Mar / Light shaking (MMI IV) / rattling, vibrating / 5-10 s : My partner and I were working in bed and we could feel the earthquake distinctively. It lasted about 10 second with a little pause in the middle. The bed was vibrating but no objects fell around us. | 5 users found this interesting.

Look up aftershocks or earlier quakes
Aftershocks
More info
Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 16 km
2 (=6 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 7 km (4 mi).
Aftershocks typically occur during the days and weeks following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the
map below to verify).
