Overview

• The National Center for Seismology recorded a 4.3 magnitude earthquake in Tibet at 06:58 IST on July 30, followed by a 4.0 magnitude event at 11:31 IST, both at a depth of 10 kilometres.
• Shallow depths increased the strength of ground shaking and raised concerns about additional aftershocks, prompting local authorities to declare heightened alert status.
• Earlier on July 30, an 8.8 magnitude quake off Russia’s Kamchatka Peninsula triggered tsunamis across the Kuril Islands and Japan’s Hokkaido, sparking warnings for Japan, Alaska, Hawaii and parts of China’s east coast.
• Japan’s Meteorological Agency detected waves up to 40 centimeters in 16 locations, and China’s Tsunami Warning Center issued coastal alerts for Shanghai and Zhejiang provinces.
• Heavy rainfall in Tibet on the same day caused flooding in Nepal’s Rasuwa District and along the Trishuli River, leading Nepalese officials to issue flood warnings for several districts.
