Earthquake Hazards Mitigation
Here on the Big Island, we feel small earthquakes on a regular basis, and magma movement underground that precedes eruptive activity produces low-level tremor.
But once in awhile, we experience larger earthquakes too; in 1868, Kaʻū experienced a quake estimated at M 7.9 that knocked down every wall and building in the district, and took the lives of 81 people. These large earthquakes originate deep within or below the island, in areas where the rock itself is structurally weak.
Compared with other natural hazards, earthquakes are unique, because there is no warning. For all other natural disasters, you have a few minutes to a few days of advance notice that the tsunami, lava flow, or hurricane is on its way. But there is no warning for earthquakes. They can happen at any time. That means you have to be prepared at all times, because you never know when the next one is coming.
You can’t stop an earthquake. But you can lessen the effects of that earthquake--thus protecting your home, your life, and your family. Don’t make the mistake of thinking, “Well, there's nothing I can do anyhow; if it comes, it comes.” You can make your house safer…and after all, isn’t your family worth it?
