I've been having a certain amount of fun posting here, as well as on Twitter and Facebook, about how warm LA has been as the rest of the country freezes. This seems to have annoyed many friends and longtime readers, so I thought I should take note of a major downside of life in LA. Or, more precisely, life in my part of LA.
The state has just released an updated map of the active Hollywood fault. I won't tell you exactly where my house is on this map. Suffice it to say, however, that it's not on the dashed red line but it is well within the part of orange fault zone west of the 101. Yikes!
FWIW, here's what I know about the potential for activity on the fault:
- TYPE OF FAULTING: left-reverse
- LENGTH: 15 km
- NEARBY COMMUNITIES: Hollywood, Beverly Hills, Glendale
- MOST RECENT SURFACE RUPTURE: Holocene
- SLIP RATE: between 0.33 mm/yr and 0.75 mm/yr
- INTERVAL BETWEEN MAJOR RUPTURES: 1600 years (?)
- PROBABLE MAGNITUDES: MW5.8 - 6.5, alone; larger if rupture is simultaneous with an adjacent fault
