The earthquake in Kamchatka is the largest worldwide since 2011. Its location has been very seismically active in recent months.
It’s far better to evacuate early and orderly than do it late in a panic. That’s why authorities around the Pacific are taking no chances as a tsunami threat looms.
Underwater waves could also be used to reduce the risks of tsunamis and to improve their early warning systems.
We need early warnings, stronger seawalls, and people who know the risks.
We can’t rule out the possibility today’s earthquake was not even the biggest event in this sequence, although as time passes the likelihood of a larger associated event decreases.
Earthquakes originating underneath the ocean are often accompanied by tsunami warnings. Here’s what determines the tsunami risk.
As Fiji did after 2016’s catastrophic cyclone, Tonga will likely face challenges with building materials and costs, and low levels of technical expertise. But these can be overcome.
We can’t prevent natural disasters from happening, but we can be better prepared for when they do.
Climate change doesn’t just affect the atmosphere and the oceans, it affects the Earth’s crust as well.
