Heavy earthquake in front of Alaska: Tsunami warning canceled!

Heavy earthquake in front of Alaska: Tsunami warning canceled!

Popof Island, USA - On July 17, 2025, a strong earthquake of the strength 7.3 shook the coast off Alaska. According to the information from OE24 , the ground breath occurred on Wednesday at 12:37 p.m. The earthquake stove was at a depth of about 20 kilometers in the sea. At first a strength of 7.2 was reported, but the USGS later corrected them to 7.3.

The authorities temporarily published a tsunami warning for a coastal section of over 1.100 kilometers in southwestern Alaska. However, this was lifted late Wednesday afternoon, as 20min . The population was initially asked to go to higher areas or inland, but was soon able to return to their houses because the municipality of Unalaska gave the all -clear. Fortunately, there have been no reports of major damage or injuries so far.

tsunami warning and their cancellation

The national tsunami warning center had confirmed that there was a tsunami with "some effects", but the USGS estimated the risk of damage or victim as low. The security measures in the region, where the residents live in earthquake -proof buildings, have apparently proven themselves. In Anchorage, the largest city of Alaska, no Tsunami risk was found.

A look at the history of Alaska shows that the country is in the geographically active Pacific fire ring and is therefore regularly affected by earthquakes. In March 1964 the strongest earthquake in North America occurred with a strength of 9.2 that triggered a devastating tsunami and demanded over 130 fatalities.

research and early warning systems

While the security measures in Alaska are still in focus in Alaska and the reaction to earthquakes, research is intensifying its efforts to better understand the risks of earthquakes and tsunamis worldwide. The Multi-Marex project was recently launched, under which innovative early warning systems are tested. Here, sensors are used on the sea floor to recognize dangers at an early stage, which should contribute to improving coastal protection in the long term. The Geomar Helmholtz Center for Ocean Research in Kiel reports more on this on its website geomar.de .

The importance of such systems is also illustrated by the events in Alaska, which show how important fast action and preventive measures are to protect the population from natural disasters. The connections between earthquakes and tsunamis must continue to be researched more intensively in order to increase the safety of the coastal regions worldwide.
