As it is our policy to keep you informed, it seems our old friend El Heirro is threatening to reawake. The concern here is if El Heirro has a significant quake causing a massive landslide, the East Coast of the US could experience a significant tsunami of 10-30M and with only a 6-8 hours notice.
Two years after a new underwater volcano appeared offshore of El Hierro in the Canary Islands, earthquake swarms and a sudden change in height suggest a new eruption is brewing near the island’s villages, officials announced Friday (Dec. 27).
After the announcement, one of the largest temblors ever recorded at the volcanic island, a magnitude-5.1 earthquake, struck offshore of El Hierro at 12:46 p.m. ET (5:46 p.m. local time) Friday,December 27, 2013, the National Geographic Institute reported. Residents on the island reported strong shaking, and the quake was felt throughout the Canary Islands, according to news reports. The earthquake’s epicenter was 9 miles (15 kilometers) deep.
Before the earthquake struck early Friday afternoon, the island’s volcano monitoring agency, Pelvolca, had raised the volcanic eruption risk for El Hierro to “yellow.” This warning means that activity is increasing at the volcano, but no eruption is imminent. A similar burst of activity prompted a yellow warning in June 2012, but the volcano soon quieted down.
Parts of El Hierro have swelled nearly 3 inches (7 centimeters) in the past week, with the growth centered between El Pinar and La Restinga, according to Involcan, the Volcanological Institute of the Canaries.
More than 550 earthquakes rattled the island between Monday and Wednesday, also centered on La Restinga. About 30 of the earthquakes were greater than magnitude 3, Involcan said. The earthquakes are triggered by magma rising underground, fracturing rocks and swelling the surface as the hot rock reaches upward. “The earthquake swarm corresponds to a new magmatic intrusion,” Involcan said Friday morning in a statement.
Friday’s preliminary magnitude-5.1 earthquake was on the opposite side of the island from the ongoing swarm.
Our concern is that MSM is not reporting this and our USGS site has only reported the 5.4 quake that occurred today. So heads up East Coasters and let everyone you know what is going on. Pay close attention for the next few days and be aware of what is going on in La Palma. You can monitor activity closely at European Seismology Center and monitor for a tsunami at Atlantic Tsunami Warning Center. As always make sure you have your bug-out bag at the ready and your evacuation route well planned. Since there is such a high density population on the East Coast, the sooner you are aware, the more likely you will get to high ground in time.
To be clear here, we are not saying a large quake is eminent or that a tsunami will be generated. What we are saying is earthquakes have been swarming and growing in intensity. It is time to pay close attention as the potential for a large quake with a resultant tsunami has significantly increased in the last 48 hours.
