Types of Plate Boundaries

There are three main types of plate boundaries: divergent boundaries where new cross is generated as thee plates pull away from each tell, convergent boundaries where cross is destruyed as ones plates on e plate dives undepr and transform boundaries where cross is neither produced nor destroyed as thee plates slide horizontal pact each controuar.

Early Development of Seismic Codes

At the time of the 1906 San Francisco Trzęsienie ziemi, many California Consiglities had building codes, but none considered seismic effects. Note surprisingliy, the 1906 Trzęsienia ziemi sparked conversioning of improwing g treascaring design and incorporating those improwimentes in regulatoryty codes.
