Friday morning an earthquake of magnitude 7.8 occurred in the Kamchatka Peninsula in Russia. The quake hit at 6:58 a.m. in local time, which is about 80 miles east of Petropavlovsk-Kamchatsky. It was reported by the US Geological Survey that the depth of the quake was approximately 10 kilometres. The earthquake triggered tsunami alerts on the eastern coast of Russia as well as sections of the Kuril Islands. The emergency services were rapidly on the move placing every team on high alert.

Tsunami Alert and Impact
Tsunami warnings were declared on the eastern coast of Kamchatka which cuts deep into the Bering Sea and the Pacific Ocean. The waves of tsunamis were between 30 and 62 centimetres (one to two feet) at different points of the coast of the peninsula. Part of the Kuril Islands which are located north of Japan, was also covered by a tsunami warning.
Precautions were taken by the US Pacific Tsunami Warning Centre giving warnings to the coasts of Alaska. A few hours later however, it lifted the advisory after it had confirmed that there was no major threat of a tsunami. The US National Weather Service assured that it was not threatened by destructive waves along the US West or Canadian coastline. The authorities urged people around the impacted regions, particularly those who reside in Alaska, against visiting the beaches and waterways until the authorities give the word that it is safe.
Vladimir Solodov, Governor of the Kamchatka region, commented on the situation. “This is once again testing the resilience of Kamchatka residents,” he said on Telegram. He confirmed that emergency services were on high alert and highlighted immediate assessments of social and residential structures. So far, there have been no reports of damage or casualties from the earthquake or tsunami waves.
Background: Kamchatka’s Seismic Activity
The area has had a number of strong earthquakes this year. In July, an earthquake of magnitude 8.8 was felt and caused massive tsunami warnings across the Pacific. That tsunami created 3-4 metre waves along certain parts of the coast, causing evacuations of people in most settlements. The area had another 7.4 magnitude earthquake last week.
The ongoing quake highlights a shaky seismic profile of Kamchatka. The common faulting at shallow depths, typically between 10 kilometres and the ocean floor, has been observed by geologists which increases the chances of sudden and powerful tremors. The present list of earthquakes since July gives credence to the idea of continued geophysical instability of the area.

Tsunami Formation Explained
Tsunamis are usually created when there is violent movement of water as a result of huge underwater earthquakes. These are waves that move across oceans and may result in intensive flooding and powerful torrents and in some cases lasting hours or days. The geography of the place and the ocean bottom contribute to the magnitude and extent of tsunami waves.
The coastline of the Kamchatka Peninsula with its massive exposure to the Pacific Ocean and the Bering Sea, is still highly susceptible to such wave activity. This weakness has resulted in the authorities responding promptly to tsunami warnings after the earthquake.
Emergency Response and Precautions
Emergency services in Kamchatka went into response to the protocols in response to the quake. Governor Solodov urged residents to calm down. His message highlighted the urgency and the government intervention and monitoring of the possible affected infrastructure.
Other neighbouring areas were also covered by similar warnings, which allowed precautionary evacuations of shorelines and limited access to coastal areas. The reaction as a whole indicates the lessons learnt in the past earthquake and tsunami in the Pacific rim.

International and Regional Effects
The earthquake was of concern not only in Russia but also in the Pacific Basin. Pacific Island community members of Alaska, Hawaii and others were the first to receive tsunami watches or advisories. The Hawaii Pacific Tsunami Warning Centre in Honolulu had confirmed that there was no destructive tsunami to Hawaii or any US territory.
This was a rather tremendous earthquake but it did not have a tremendous tsunami damage along the coast of Russia. Nevertheless, analysts indicate the persistent danger in the area and they urge continued vigilance.
Kamchatka is also a sensitive region of seismic studies and surveillance because it is known to have experienced major earthquakes and tsunamis. The occurrence of this in the recent past demonstrates the fact that international coordination in disaster preparedness remains necessary.
