Who writes earthquake in Hawaii
Top insurer groups from the NAIC market share report; the state's list carries no lines of authority.
Ms & Ad Insurance Group wrote the most earthquake in Hawaii in 2025, $6.0M and 19.6% of the state's premium; the top five groups hold 57%. Hawaii's company list doesn't say which lines each company is licensed for, so the ranking below is the NAIC's top 10 groups; every licensed company is on the Hawaii page.

Method and source
Source: the Hawaii insurance regulator company list, read 2026-10-18. Source is the directory of authorized insurers inside the 2025 Annual Report of the Insurance Commissioner (PDF pages 47-92; business year 2024, directory current as of the report date). Every row has a 5-digit NAIC code. No company type (stock/mutual/etc.) is given, so type is empty for all; the list mixes life/health, P&C and title insurers and 'lines' carries the report's classes-of-insurance letters as given: AH=Accident & Health or Sickness, L=Life, C=Casualty, M=Marine, IM=Inland Marine, OM=Ocean Marine, P=Property (Fire), S=Surety, T=Title, V=(Motor) Vehicle. 'classes_raw' is the verbatim class string; 'note' holds the report's parenthetical restrictions/remarks (e.g. Credit Only, Workers Comp Only, Reinsurance, V added effective ..., Redomesticated ...). 'domicile' is the state of the home office printed under each name (blank for Canadian home offices and one entry whose state is missing in the PDF); 'home_office' is the city. 'since' is the Hawaii admission date. Risk retention groups registered in Hawaii appear in the same directory and are kept. Captive insurers (no NAIC codes) and HMOs/mutual benefit societies/dental insurers listed on later pages are not included. Hawaii publishes no surplus lines eligibility list (export-list state), so surplus_lines is empty. "Premium" is direct premium written in the state for the year shown; "share" is that company's part of the state total for the line. A company can be licensed for a line and write none of it, and a surplus lines insurer can write a line without a state license for it.

Someone will insure it. I find who.
Send what you need covered and what happened before. I match it to the companies that take it, down to the last-resort plan if it comes to that. I'm licensed in 48 states and Washington, DC and your request stays with my agency, not passed to another agent. In Florida and Washington, where my licenses are still being issued, a partner agency in your state helps in the meantime.
