California just shook again. Most property owners still have no earthquake insurance.

On Thursday, August 13, 2026, a magnitude 3.8 earthquake struck the East Bay near the Oakland–San Leandro border, on the Hayward Fault. USGS first reported it as high as 4.1, then revised it to 3.8. BART trains stopped. Thousands of people felt it from Santa Rosa and Sacramento down to Santa Cruz. Two aftershocks followed. The same night, a magnitude 2.5 hit off Malibu. The day before, a 2.6 was recorded near Valencia.

This is not one isolated tremor

California has been reminding property owners all summer. According to the U.S. Geological Survey and contemporaneous news reports:

• August 13, 2026 — M3.8 Oakland / San Leandro. Centered near the Oakland Zoo and Bishop O’Dowd High School, essentially on the Hayward Fault. Felt across the Bay Area. Aftershocks of M3.0 and M2.8. No major damage reported this time. That is luck, not a guarantee.
• August 13, 2026 — M2.5 near Malibu. USGS, about 3 miles west of Malibu, later revised from 2.7.
• August 12, 2026 — M2.6 near Valencia.
• July 13, 2026 — M4.3 west-southwest of Johannesburg.
• July 12, 2026 — M4.1 near Frazier Park.
• July 11, 2026 — M4.4 near Covelo (revised up from 4.2), felt in Fort Bragg, Willits, and Ukiah.
• June 24, 2026 — M5.6 north of Redwood Valley / near Willits. Mendocino County’s strongest in that area since 1940. Items thrown off store shelves, thousands without power, some injuries, hundreds of thousands of MyShake alerts. USGS later reviewed it as M5.6 after an initial 6.0-class alert.

None of these events tells you the date of the next damaging earthquake. They do tell you the ground is active on the same fault systems that run under Bay Area homes, Los Angeles County properties, and Northern California towns. The Hayward Fault, in particular, is the one Bay Area owners should not shrug off. Thursday’s epicenter sat on it.

Your homeowners policy will not rebuild the house after shaking

The California Department of Insurance is blunt: standard homeowners, renters, and condominium insurance generally excludes damage caused by earthquake. You buy earthquake coverage separately, through a participating insurer offering California Earthquake Authority (CEA) coverage or through a stand-alone earthquake market.

Fire that starts because of an earthquake is usually still covered by the regular homeowners or renters policy. Cracked foundations, shifted structures, broken contents, collapsed chimneys, and the hotel bill while the house is uninhabitable from shaking are not. That is the gap.

CDI’s 2024 earthquake data call found only about 15% of homeowners policies and about 12.5% of the overall residential market also carried earthquake coverage. After the 1994 Northridge earthquake (M6.7), take-up climbed toward 40%. Then it faded. The faults did not.

What an uninsured loss actually looks like

Imagine a $1,000,000 rebuild cost on a San Francisco, Oakland, or Peninsula home. Without earthquake insurance, that repair bill, plus temporary housing, plus the mortgage you still owe, is yours. FEMA is not a rebuild fund. A large share of federal disaster help, when it exists, is loans you repay.

With earthquake insurance, you still have a deductible, and it is usually a percentage of the dwelling limit, not a $1,000 flat amount. A 15% deductible on $1,000,000 of dwelling coverage is $150,000. That is still a serious number. It is a different universe from funding the entire rebuild yourself.

Condo owners have a second problem: the HOA may have little or no earthquake coverage on the building, or a huge master-policy deductible that gets assessed back to owners. Landlords can lose rental income and still owe the loan. Renters lose furniture, electronics, and a place to sleep.

You may not be able to buy it after the one that matters

Earthquake insurance does not pay for damage that already happened. After a significant event, insurers can pause new applications in the affected area. Waiting until the house is already cracked is waiting too long.

Thursday’s 3.8 did not close the market. A larger Hayward or San Andreas event could. The time to compare CEA and stand-alone options is while you can still get a quote, not while you are standing in the street looking at the chimney.

What to do this week

1. Pull your current homeowners, condo, or landlord declarations. Confirm there is no earthquake endorsement.
2. Estimate rebuild cost, not Zillow value. Those are different numbers.
3. Decide what deductible you could actually fund in cash or credit.
4. If you own a condo, get the HOA master policy and any earthquake deductible or assessment language.
5. Ask us to shop CEA and stand-alone earthquake options for the address. Retrofit records (bolting, cripple-wall bracing) can matter for price.

How ESI Insurance Brokers helps

ESI Insurance Brokers is a California brokerage. We help homeowners, condo owners, landlords, and renters compare earthquake options next to the underlying property policy, turn percentage deductibles into dollars, and flag condo loss-assessment and loss-of-use gaps. We work with multiple markets. The point is not to scare you into the first form you see. The point is to stop treating “I felt a quake on Thursday” as entertainment and start treating it as a balance-sheet risk.
