The devastating 7.4 magnitude earthquake that struck western Colombia on August 10, killing hundreds and damaging buildings and infrastructure, is another reminder of how quickly a major earthquake can impact entire communities. For earthquake-prone regions like California, preparedness must begin before the shaking starts.

We cannot predict the next major earthquake, but we can take steps to reduce its impact. Identifying vulnerable buildings and completing seismic retrofits can help reduce damage, protect investments, and, most importantly, save lives. Stronger buildings mean safer communities.

Mayor Bass Applauds LA’s Progress On Retrofits

Venezuela’s doublet leaned toward Caracas

At 18:04 (6:04 p.m.) local time on June 24, 2026, the coast of north-central Venezuela moved — twice.

The devastation some of the quakes have wreaked has, however, been striking.

Japan absorbed two significant earthquakes on the same day Sunday, August 23, 2026 — first a magnitude 5.9 intraslab rupture that awakened millions of Tokyo-area residents at 2 a.m. and injured at least 37 people across five prefectures, then a magnitude 6.0 event off the southern coast of Hokkaido that evening — extending what has already become an unusually active seismic year for the archipelago.

Lead & Asbestos: Do It Right, Make It Safe

Many older apartment buildings contain hazardous materials such as lead and asbestos. While these substances may not always be visible, they can pose serious risks to both human health and the environment if not handled properly.

Unfortunately, some property owners underestimate these dangers or attempt to remove these materials without following the required regulations. Trying to bypass proper procedures can put workers, tenants, and surrounding communities at risk.
