Core Points - A series of earthquakes have awakened seven volcanoes on the Kamchatka Peninsula, leading to a phenomenon referred to as a "volcanic eruption festival" [1] - The peninsula has shifted 2 meters southeast due to these geological activities [1] - The strongest earthquake occurred on July 30, with a magnitude of 8.7, affecting the region and causing significant volcanic activity [1] Volcanic Activity History - Volcanic activity in Kamchatka and the Kuril Islands is believed to have started 50,000 to 60,000 years ago, with the most intense activity occurring around 1,800 years ago [2] - The volume of volcanic debris from that period reached 18 to 19 cubic kilometers, with eruption columns rising up to 23 kilometers [2] - Historical eruptions have caused extensive ecological damage, including the destruction of at least 500 square kilometers of life and approximately 12,000 square kilometers of vegetation [2] Natural Disaster Risks - Volcanic activity can trigger other natural disasters, such as glacier melting and mudslides, posing risks to local communities [3] - The Kamchatka coastline has faced at least 24 tsunamis in the past 300 years, with significant events recorded in 1737 and 1952 [3] - The region is under constant threat from tsunamis, which have historically resulted in loss of life and property [3] Historical Accounts - Historical records by Stepan Krasheninnikov indicate that volcanic eruptions often precede large-scale eruptions with years of smaller eruptions [4] - Local interpretations of volcanic activity have been shaped by cultural beliefs, with some communities viewing volcanoes as the resting place of the deceased [4] - Modern responses to volcanic eruptions have improved, with better housing structures and public awareness regarding volcanic ash [4][5] Preparedness and Response - Strong volcanic eruptions typically have precursors such as small earthquakes and distinctive rumbling sounds, prompting evacuations from danger zones [5] - Historical records show that catastrophic eruptions can lead to severe wildfires and long-lasting ecological changes, turning vast areas into deserts [5]

Group 1 - An 8.7 magnitude earthquake occurred in the Avacha Bay area of the Kamchatka Peninsula on July 30, leading to approximately 1000 aftershocks detected in the region [1] - The aftershocks ranged from the minimum measurable magnitude to about 7, with expectations of thousands more aftershocks in the coming months [1] - The Kamchatka Volcanic Natural Park reported an eruption of the Klyuchevskaya Sopka volcano following the earthquake, with ash reaching approximately 6000 meters above the crater [1] Group 2 - The earthquake caused a tsunami with wave heights reaching up to 5 meters, prompting the evacuation of around 2700 people to the Kuril Islands [1] - Flooding in the tsunami-affected areas has receded as of the same day [1] - Experts believe that the earthquake is likely the final phase of over a year of seismic activity in the Kamchatka region, with a low probability of larger earthquakes occurring within the year [1]

自然资源部海啸预警中心预报员 侯京明：海啸的预警分为红橙黄三级，（海啸波幅）三米以上是红色预警，（海啸波幅）一到三米是橙 色预警，（海啸波幅）30厘米到一米是黄色预警。 海啸来了如何防范 央视网消息：海啸是如何形成的，海啸预警分几级，一起来了解。 海啸是一种具有强大破坏力的海浪，由风暴或海底地震造成，并伴随巨响。海啸通常由震源在海底下50千米以内、里氏地震规模6.5以上 的海底地震引起。海啸的特征之一是速度快，在海洋的传播速度大约每小时五百到一千公里，而相邻两个浪头的距离也可能远达500到650千 米。地震发生的地方海水越深，因海底变动而涌动的水量越多，形成海啸之后在海面移动的速度也越快。海啸破坏力强，给人类带来的灾难是 巨大的。因此，相关部门会视情况提前发布海啸预警信息，提醒人们注意防范。 海啸来临前，所有人员应远离沙滩及沿岸低洼地区。如自己身处海滩，感到地面有强烈震动、发现海水突然退却或听到像即将来临的火车 一样的咆哮声，这是海啸来临前的征兆，应立刻跑往高处或稳固建筑物的高层。 海啸的破坏力与沿岸地形有很大关系，遇到一些坡度比较大的地区或是"U型"港湾，就有可能引起波幅的增大，导致灾害发生。即使小的 海啸 ...

Core Points - A 6.5 magnitude earthquake occurred near the Kamchatka Peninsula on July 30, with a depth of 68 kilometers [1] - An 8.7 magnitude earthquake, the strongest in the region since 1952, was recorded earlier on the same day [1] - Tsunami warnings were issued by multiple countries along the Pacific coast due to the strong earthquake [1] Summary by Category Earthquake Details - The 6.5 magnitude earthquake was located 178 kilometers from the North Kuril Islands [1] - A subsequent 5.3 magnitude earthquake was recorded in the same area [1] - The 8.7 magnitude earthquake is noted as the strongest in the region since 1952 [1] Tsunami Warnings - Tsunami warnings were issued across various Pacific nations, with observed tsunami waves reported [1] - New Zealand's National Emergency Management Agency issued a tsunami warning, advising the public to stay away from beaches and ports [1] - Chile's National Disaster Prevention and Response Center issued a red tsunami alert, requiring coastal residents to evacuate to safe areas [1] Current Status - As of the latest update, the Kamchatka regional emergency department lifted the tsunami warning [2] - Japan's Meteorological Agency downgraded all tsunami warnings to advisory level [2]
