Look for signs of moisture or water damage (water leaks, standing water, water stains, condensation, etc.). Check around air handling units (air conditioners, furnaces) for standing water. Routinely inspect the evaporator coils, liner surfaces, drain pans and drain lines. Search areas where you notice mold odors.
1 Where do tsunamis most often occur in the world? 2  Tsunamis occur most often in the Pacific Ocean and Indonesia because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones. Tsunamis occur most often in the Pacific Ocean and Indonesia because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones. 2  However, tsunamis have also occurred recently in the Mediterranean Sea region and are expected in the Caribbean Sea as well.
Earthquakes that generate tsunamis most often happen where Earth's tectonic plates converge, and the heavier plate dips beneath the lighter one. Part of the seafloor snaps upward as the tension is released. The entire column of seawater is pushed toward the surface, creating an enormous bulge.
