Aftershocks from Friday's 5.1 earthquake may be moving northeast

If the earthquakes do move to the northeast, they could shift from the Puente Hills thrust fault system toward the Whittier fault.
There is precedent for earthquake aftershocks jumping faults. The Whittier Narrows earthquake, a magnitude 5.9, struck on the Puente Hills thrust fault system on Oct. 1, 1987. Three days later, a magnitude 5.6 aftershock hit on a different fault, Hauksson said.

YVO mentions in their post that this swarm is in area currently in the midst of an uplifting episod….which has some similarity to past events in 1996 and 2003.
[link to earthquake.usgs.gov]

A snippet from the USGS report:
“Today’s event is the largest earthquake at Yellowstone since February 22, 1980, and occurred near the center of a region of recent ground uplift described in a YVO Information Statement on February 18, 2014. The Yellowstone Volcano Observatory has been tracking this uplift episode for about 7 months”. [link to volcanoes.usgs.gov]

“As discussed in the March 3, 2014 YVO Monthly Update, seismicity in the general region of the uplift has been elevated for several months. A previous period of uplift in this area occurred between 1996 and 2003, and it was also accompanied by elevated seismicity”.

While all this data is interesting, the general consensus is no big deal other than “normal” fluctuations in both uplift and related seismicity.

Yellowstone Earthquake: Volcanic Eruption Not Expected After Strongest Tremor in 29 Years

By Nick Wiltgen

Published: Mar 30, 2014, 2:20 PM EDT weather.com

Yellowstone National Park was shaken by its largest earthquake in 29 years Sunday, but scientists say there is no concern that the quake will lead to an eruption of the Yellowstone Caldera, a supervolcano located in the park.

The magnitude-4.8 earthquake struck inside the park boundaries at 6:34 a.m. MDT Sunday. The epicenter was near the middle of the park, near the Norris Geyser Basin, according to Peter Cervelli of the U.S. Geological Survey.


The quake, the largest since another 4.8 tremor in 1985, was preceded by two foreshocks measuring 2.8 and 3.0 at 12:23 a.m. and 4:36 a.m. Sunday, respectively. The main shock was then followed by at least four aftershocks ranging in magnitude from 2.5 to 3.3 later Sunday morning.

There were no immediate reports of damage. There are few visitors in the park this time of year.

Cervelli said the earthquake is interesting scientifically because of the length of time since a quake of equal intensity. He added that data gathered from earthquakes give scientists great insight into volcanoes and tectonics.

However, Cervelli said there are no hazardous implications, and that the Yellowstone Caldera is not about to erupt. [link to www.weather.com]
