Chile Tsunami – review

Yesterday, an earthquake with the magnitude of 8.2 caused a tsunami off the W coast of Chile. SeismoNow had observed some signs that a major earthquake may occurr soon.

The Tsunami most severely affected the coasts of Chile and Peru. Waves of nearly 2m and 11cm above normal sea level were measured with the help of sensors in Chile, but there might as well have been significantly higher waves.

The tsnami was registered throughout the entire pacific ocean.

TSUNAMI IN THE PACIFIC

A tsunami warning remains in affect in Chile and Peru. The earthquake occurred near the coast of northern Chile with a magnitude of 8.2. So far, stations in both Chile and Peru have reported the tsunami to have come ashore. The highest wave reported by a station was 2.11m in Iquique, however the actual hight in many places will most likely have been significantly higher. Based on the PTWC, here is the list of the coming strike locations.

Greece is being rattled by earthquakes

Greece is currently being rattles by large amounts of earthquakes. This is a very unusual state, even for this very country which experiences around 10 earthquakes daily. SeismoNow is watching closely. Because of the high seismic activity in Greece the current world activity status is “high”. This unusual activity started on the 26th of January, when out of the dark, a magnitude 6.1 earthquake struck just W of the Pelopones peninsula. Or was it so out of the dark? The earthquake watch that was issued this morning has recently been upgraded to an earthquake warning in Greece. The earthquake that struck Greece this morning is still the largest toppic on the seismology websites and now also is beginning to flow into the news as well. Especially in greek news, of course. The number of eyewhittness reports has increased to stunning 64 only on EMSC, all the news agencies and other seismology services not included. In only 5 hours so many people reported. The earthquake on the 26th January over 120 people reported it, there were 3 surveillance camera videos that EMSC got access to. Since the earthquake, alone at that very location 13 aftershocks have occurred. At the beginning they came in a two-minute rhythm. Now at the epicenter aftershocks occur around every half an hour. The earthquake in W Greece has caused a sruprising increase in seismic activity in the dodecanese islands, the vocano Nisyros had a very concerning tremmor of magnitude 3 on Sunday. Or actually three earthquakes at the very same time, just at different depths. The seismic activity in Greece seems very dangerous, and could seemingly spread around the globe. Before the earthquake on the 26th of January there were relatively many earthquakes reported from S Greece. Not so many from Greece and especially not from W Greece. But it is surely possible that the earthquakes in S Greece and the ones in W Greece were connected, since the earthquakes in W Greece have now spread to the dodecanes islands, and therefore they seem to be travelling around the faultlines in Greece.

Earthquake watch upgraded: Warning for Greece

The earthquake watch that was issued this morning by SeiosmoNow has now been úpgraded to a warning in Greece. This means that it is very likely that several earthquakes that might as well be felt will strike within the next hours. These will most likely be aftershocks caused by the big 6.1 earthquake this morning. But you cannot be sure if these are aftershocks, since there was a similar case in 2011, just on the other side of the earth; in Japan. 1 (?) or a few days before the 11th of March a magnitude 7 earthquake struck off the E coast of Honshu, Japan. It caused quite significant damage and even a small tsunami that reached a peak altitude of 3m and caused slight damage at the Japanese coast. The news went wild, reporting about the big earthquake that struck Japan and cause “major damage”. Then came teh 11th of March, and soon it was clear that the earthquakes that followed the magnitude 7 earthquake were not aftershocks, but rather foreshocks. This was only noticed by SismoNow, not by larger earthquake services. Is it possible that this earthquake sequence is similar to that case? Will an even larger earthquake follow?

Greece at unrest

Currently Greece is being shaken by one quake after the other. On the 26.1. there was a magnitude 6.1 quake just W of Greece, this morning, about 1 hour ago, a further 6.1 quake struck at the very same location. On EMSC 43 testimonies area already available by people that were right in the earthquake. Here the location of the earthquake. The maps are from http://www.emsc-csem.org

The nearest town to the epicenter was Lixourion. Based on reports that EMSC got, the earthquake was felt still in Italy, in Lecce. On the islands close to the epicenter the earthquake was slightly damaging. Most reports came from Patras, and some came from Athens. Here the map.

02.03 mag 6.1

This was not the first quake of its kind. There have been similar quakes earlier. But the large number of quakes that started W of Pelopones and have now moved E to affect the dodecanes islands (see the page “nisyros” for live seismograms from there), are really interesting and might serve as a warning. This was probably not a strong aftershock from the 26. quake, but rather just a very own earthquake. 19 minutes ago, there has just been another aftershock.
