Re: ** TSUNAMI ** Costa Rica Pacific side

Local news Noticias Repretel said they had phone reports of serious damages in houses in the canton of Santa Cruz.
The Red Cross and National Emergency Commission have not reported any casualties.
In many areas across the country, residents reported cellphone networks down, but local telephone lines and Internet service is working in many areas.
