Overview
- New 2023–2025 studies from the Institute of Volcanology and Seismology conclude that parts of Petropavlovsk‑Kamchatsky, Yelizovo and Vilyuchinsk could experience shaking up to intensity 10.
- Researchers highlight soil liquefaction as a major driver of destruction that can destabilize buildings and infrastructure during strong shaking.
- Proposals include a statutory move toward 2–3‑storey development and high‑technology vibration testing of building series before approval.
- Scientists call for urgent audits of critical infrastructure and facilities with large public occupancy to assess seismic resilience.
- Authorities reported 12 offshore aftershocks of magnitude 3.5–5.5 in the past day that were not felt on land, with seismicity labeled extremely high and volcano monitoring intensified.
